How to Cut a Stripboard to Size?

Cutting a stripboard to size is essential when working on custom electronic projects, as the default size of the board might not always fit your design requirements. While the process may seem simple, precision is important to ensure a clean cut and a properly functioning circuit. Here’s a step-by-step guide on how to cut a stripboard efficiently:

1. Measure the Required Size

Before making any cuts, it’s crucial to measure the exact size of the stripboard you need for your project. Use a ruler or measuring tape to determine the length and width of the area you will be working with.

After measuring, use a pencil or fine-tip marker to draw cutting lines on the board. It’s essential that the lines are precise and straight. You can use the pre-drilled holes on the stripboard as a guide, ensuring that your cuts are aligned with the rows and columns of the board.

2. Prepare the Work Area

Set up your workspace to ensure that you have a safe and stable area for cutting. Place the stripboard on a flat, stable surface, such as a cutting mat or a workbench. To avoid slipping while cutting, use clamps or a vise to secure the stripboard in place.

3. Cutting Tools

Choose the right tool for the job. A few common tools for cutting a stripboard include:

Fine-toothed hacksaw: Ideal for making precise cuts through the stripboard material without damaging the copper strips.

Rotary tool (Dremel): A rotary tool with a cutting wheel can make cleaner and more controlled cuts. It’s especially useful for intricate or delicate work.

Score and snap method: For small, simple cuts, you can score the board with a sharp utility knife along the marked lines. Once scored deeply, you can snap the board along the cut line.

4. Cut Carefully

Once your stripboard is secure and you have chosen the right tool, it’s time to cut. Begin by gently sawing along the marked line. Use steady, even pressure, allowing the saw to do the work. Avoid rushing the cut, as this could lead to uneven or jagged edges. For more precise cuts, guide the rotary tool along the cutting line with steady pressure. The rotary tool can provide smoother edges, but take care to maintain control over the tool for safety and accuracy.

5. Finish the Cut

After the board has been cut, you may notice that the edges are rough or uneven. Smoothing the edges will prevent accidental shorts or damage to the board’s components.

File the edges: Use a fine-grit file or sandpaper to carefully smooth out the rough edges of the board. This step is particularly important if you are working with sensitive components or high-density circuits, as sharp edges can lead to unwanted contact with other parts.

Check the copper strips: After smoothing the edges, inspect the copper strips on the cut board. Ensure that no copper traces have been damaged during the cutting process. If necessary, you can use a small utility knife or a file to clean up any rough spots near the copper strips.

6. Cutting Strips (Optional)

In many cases, you’ll also need to cut the copper strips on the underside of the board to isolate specific circuits or prevent unwanted connections. Use a small drill bit, sharp knife, or strip cutter to make small breaks in the copper strips where needed. Carefully break the strip without damaging the surrounding area. These cuts should align with your circuit design to ensure proper functionality.

Difference Between a Strip Board and a Breadboard

While both strip boards and breadboards are used for prototyping, they have distinct differences:

Strip boards have fixed copper strips on one side, which makes them suitable for permanent or semi-permanent circuit assembly. They require soldering to connect components.

Howevery, breadboards are used for temporary circuit designs. They have a grid of holes that allow for easy insertion and removal of components without soldering. They are ideal for testing and experimenting with different circuit configurations.

What Size is a Stripboard?

Stripboards come in a variety of sizes, allowing engineers, hobbyists, and professionals to choose the right one for their projects. A standard stripboard typically measures around 100x160mm, but smaller or larger sizes are available depending on the complexity and scope of the circuit being designed. One of the most commonly used sizes for prototyping is the 95x64mm stripboard, which offers a compact but functional area for small to mid-range circuits, like:

1. 25 x 64 mm: Has 9 rows and 25 holes

2. 64 x 95 mm: Has 24 rows and 37 holes

3. 95 x 127 mm: Has 36 rows and 50 holes

4. 50 x 80 mm: Also known as the ST1 StripBoard, this is 1.97 x 3.15 in and 1/16 in thick

5. 160 x 100 mm: A common size in the United Kingdom

6. 160 x 233 mm: A standard double height (6U) Eurocard/VME size, which is 9.2 in wide, 6.3 in long, and 1/16 in thick

Stripboards are prototyping boards made from insulating material, like fiberglass or resin-bonded plastic. One side of the board has parallel copper strips that are typically spaced 2.54 mm apart.

Layout of a Stripboard

The layout of a stripboard is quite functional:

Copper Strips: One side of the board has copper strips running parallel to each other. These strips can be cut to create breaks and allow for more flexible circuit designs.

Holes: The board is drilled with a grid of holes that line up with the copper strips. Components can be inserted into these holes, and connections can be made by soldering to the copper strips.

Breaks and Jumps: To customize the circuit, you can cut the copper strips or use wire “jumps” to make connections that don’t follow the copper strips.

Difference Between Donut Board and Strip Board

Board Structure and Layout

Donut boards, also known as perfboards, have isolated copper pads around each hole, meaning no automatic connections between adjacent holes. In contrast, stripboards have parallel copper strips that connect rows of holes, allowing predefined electrical connections.

Component Placement

On donut boards, components can be placed freely without layout restrictions. Stripboards, however, require components to align with the copper strips, which can limit layout flexibility but simplify organization for linear designs.

Wiring and Soldering

With donut boards, each connection must be made manually, which increases soldering time. Stripboards reduce wiring by offering predefined connections, but cutting the strips may still be necessary for more intricate designs.

Fault Diagnosis

Diagnosing faults on a donut board is easier because each connection is made manually, allowing clear visibility of potential issues. On a stripboard, diagnosing faults can be more difficult due to the copper strips, which may cause unintentional short circuits.

What is Copper Clad Laminate?

Copper clad laminate short for CCL, it is a foundational material in the electronics industry. It consists of a thin copper foil bonded to one or both sides of a non-conductive substrate like fiberglass or resin. This combination creates a durable and conductive material that serves as the base for creating printed circuit boards (PCBs). The copper layer facilitates the transmission of electrical signals, while the insulating substrate supports the board’s structural integrity.

CCL comes in various thicknesses and types, depending on the application. It’s a critical part of most electronic devices, from smartphones to industrial machines. Its main role is to support the etching of circuit patterns, where unnecessary copper is removed, leaving conductive paths that enable electrical connections. Below is a structure of a double sided copper clad laminate:

What is Copper Clad Board Used For?

Copper clad boards are widely used in PCB manufacturing. Their role is to provide a surface for electrical components to connect through conductive copper traces. CCLs are widely used in applications including, but not limited to:

Electronic products: Copper clad board is the basic material of electronic products, used to manufacture various electronic equipment circuit board, such as TV, radio, computer, computer and so on.

Communication equipment: Mobile phones, tablet computers, routers and other communication equipment a large number of copper clad laminate.

Computers and peripherals: Computer motherboards, graphics cards, hard disks, etc., need a large number of copper-clad boards.

Automotive electronics: Electronic equipment in modern automobiles, such as ABS, air conditioning, navigation, etc., need to use copper clad board.

Military: Electronic components in military equipment also need to use a large number of copper-clad boards.

In addition, copper clad boards are also used in industrial control, medical instruments, national defense, aerospace and other fields. With the development of technology and the increase of application demand, the use of copper clad plate in electronic products is more and more extensive, which plays an important role in promoting the renewal of social production and living tools. For example, the development of the Internet of Things and artificial intelligence, as well as the application of 5G communication technology, have greatly increased the demand for copper clad sheets. ‌

What is the Market Report for Copper Clad Laminate?

The market for copper clad laminate has grown steadily due to the increasing demand for consumer electronics, automotive advancements, and telecommunication developments. The global CCL market is expected to expand significantly over the next few years, driven by technological advancements in 5G, renewable energy systems, and electric vehicles.

Key players in this market are working to develop lighter, thinner, and more efficient CCLs to keep pace with the growing need for high-performance electronics. Manufacturers exploring new materials and production methods to reduce costs while enhancing performance. The future looks promising, with a forecast of rapid growth driven by the electronics industry’s evolution.

Is Copper Clad Better Than Copper?

Copper clad laminate is a more practical option for PCBs than solid copper because it provides the required conductive properties at a lower cost. While copper is an excellent conductor, using copper as metal core PCBs would be expensive and impractical. CCL offers the same conductivity benefits but adds a lightweight, non-conductive layer that provides structural support.

Electrical Conductivity and Cost Efficiency

While pure copper has excellent electrical conductivity, copper clad laminates (CCLs) provide a balance between cost and performance. In a copper clad board, only a thin copper layer is used, which significantly reduces the amount of copper needed compared to using solid copper. For applications like PCBs, where large surfaces need copper conductivity but do not require the full thickness of copper, copper clad is more efficient and economical.

Thermal Management

Copper clad materials often have better thermal management properties due to the substrate’s ability to dissipate heat while maintaining the copper layer’s high conductivity. Pure copper, while an excellent heat conductor, may not offer the same level of thermal dissipation when used alone in complex electronic assemblies. For instance, in multi-layer PCBs, copper clad boards help balance the need for heat management and conductivity by using the copper layer efficiently while the base material manages thermal stress.

Structural Support and Durability

Copper clad laminates provide added structural support compared to pure copper sheets. The non-conductive substrate, often made of fiberglass, resin, or other materials, adds durability and rigidity to the thin copper layer. By contrast, is soft and flexible, making it unsuitable for structural applications without some form of backing material.

Corrosion Resistance

Copper, though highly conductive, is prone to oxidation and corrosion over time, which can affect its performance in certain environments. Copper clad laminates, however, are often treated with protective coatings or layered with other materials to enhance their resistance to corrosion.

Weight Considerations

Another important factor is weight. Copper is a dense metal, and using thick copper layers can significantly increase the weight of a product. In contrast, copper clad laminates achieve high conductivity with only a fraction of the copper’s weight.

How Thick is Copper Clad Board?

The thickness of a copper clad board depends on its intended application. Standard copper thicknesses for CCL are measured in ounces per square foot, typically ranging from 0.5 oz to 2 oz per square foot. This translates to about 17 to 70 microns. For high-power applications, thicker copper, such as 3 oz or more, may be used.

On the other hand, the thickness of the laminate itself can also vary, depending on whether it’s a single-layer, double-layer, or multilayer board. The insulating substrate can range from 0.2 mm to several millimeters, depending on the application. The total thickness of the copper clad board is a combination of the copper foil and the insulating material.

How Much Does Copper Cladding Weigh?

The weight of copper cladding is typically expressed in ounces per square foot. A common weight is 1 oz of copper, which means that a square foot of copper clad board has a 1-ounce copper layer. This is approximately 35 microns thick. Heavier copper cladding, such as 2 oz or 3 oz, is also used for applications that require higher current-carrying capacity or greater durability.

It’s important to balance the weight with the application needs. Higher copper weight provides better conductivity and durability but adds cost and weight to the final product. Therefore, the choice of copper weight in CCL depends largely on the required performance and cost considerations.

Copper Clad Laminate Price

The price of copper clad laminate varies based on several factors such as copper thickness, substrate material, board size, and production volume. Standard-grade CCL is more affordable, while high-end options with specialty substrates like Teflon or ceramic tend to be more expensive.

On average, copper clad laminate costs range from $5 to $15 per square meter for common types. However, high-performance laminates designed for demanding environments, such as those used in aerospace or military applications, can be significantly more expensive.

Global market trends, material shortages, and the demand for electronics heavily influence pricing. Recently, fluctuations in copper prices and supply chain disruptions have impacted the cost of CCL. Still, bulk orders or long-term contracts with suppliers can help reduce costs for large manufacturers.

How to Cut Copper Clad Laminate?

CCL requires careful handling to ensure precise cuts without damaging the copper layer or the substrate. The cutting method will vary depending on the thickness and material, but overall, clean and accurate techniques are key.

1. Choose the Right Tools

The tools you use depend on the thickness of the copper clad laminate. Thin CCL can be cut with a utility knife, while thicker boards require specialized tools like a PCB shear or laser cutter.

2. Prepare the Work Area

Before cutting, ensure that your workspace is clean and stable. Use a flat surface to keep the laminate steady during cutting. For larger boards, use clamps to secure them in place. Always wear protective gear like goggles and a mask, especially when working with power tools to avoid dust and debris.

3. Measure and Mark the Cutting Line

Accurate measurements are crucial for a clean cut. Use a ruler or measuring tape to mark the cutting line and draw it clearly with a permanent marker. Double-check your measurements to avoid mistakes before cutting.

4. Score the Copper Clad Laminate

For thin laminates, use a utility knife to score along the marked line. Score the copper side first, then flip it over and score the substrate. Once both sides are scored, gently bend the laminate along the line until it snaps cleanly.

5. Cut Thick Copper Clad Laminate

For thicker CCL, use a guillotine PCB shear or a Dremel tool. A PCB shear provides a clean, straight cut, while a Dremel is useful for cutting complex shapes. For high precision, a laser cutter is the best choice, especially for intricate designs.

6. Deburr and Smooth the Edges

After cutting, the edges may be rough. Use a file to smooth out any jagged areas, then finish with fine-grit sandpaper.

Safety is important when cutting CCL. Fiberglass and other substrate materials can produce harmful dust. Always wear a dust mask and safety goggles, and work in a well-ventilated area to minimize exposure to particles. In addition to this, avoid over-scoring the laminate, which can damage the substrate or cause copper peeling. Make sure to apply consistent pressure while cutting to prevent uneven edges. Always prioritize safety by using proper protective gear to avoid injuries.

What is Dam in PCB?

A dam PCB refers to the solder mask dam in a circuit board, a thin barrier that separates areas of exposed copper. The dam is created to prevent solder from flowing across areas where it isn’t wanted, especially during the assembly process. These barriers ensure precise and clean soldering, which is critical for the functionality of the circuit board.

What is a Solder Mask Dam?

Solder mask dam, some engineers also call it solder resistance bridge. It is a narrow strip of solder mask material placed on the PCB between closely spaced pads or traces. It acts as a protective shield, ensuring that the solder sticks only to the pad used for the component and does not spread to adjacent areas.

By introducing a small barrier, the solder mask dam ensures that solder joints are created only in the intended areas, thereby preventing electrical shorts and other types of damage that could lead to device malfunctions or failures. They safeguard copper traces and other metal features from oxidation, contamination, and other forms of damage. In the process of batch placement in the factory, the “isolation belt” of the solder resistance bridge can effectively avoid short circuit in the welding process of the SMD component pin, so as to ensure the normal operation of the electronic equipment. It can be said: without a proper solder stop dam, solder can flow uncontrollably, causing a short circuit or damaging other parts of the board.

Types of Solder Mask Dams

There are various types of solder mask dams, primarily depending on their width and the area of the PCB they protect. Each offering different advantages depending on the PCB design’s specific requirements. The main types include open, hatched, and round dams.

Open Solder Mask Dams

Open solder mask dams are the simplest and most commonly used type. They are created by leaving a small gap around each pad or through-hole, allowing solder to flow onto these areas without spreading to nearby conductive features. Here are their advantages:

Simple to design and implement

Suitable for most PCB designs

Compatible with various soldering techniques

Hatched Solder Mask Dams

Hatched solder mask dams are similar to open dams but use a pattern of diagonal lines to create barriers around each pad or through-hole. These diagonal lines form small gaps in the solder mask, directing solder to the pad or through-hole while minimizing spreading.

It offers better protection against solder bridging compared to open solder mask dams and suitable for designs with closely spaced components or high-density PCBs.

Round Solder Mask Dams

Round solder mask dams use circular shapes to encircle each pad or through-hole. This circular barrier effectively prevents solder from flowing onto adjacent conductive features. Round solder mask dams provide the highest level of protection against solder bridging and damage. So it ideal for designs with fine-pitch components or high pin-count devices.

Role of Solder Mask Dams

The primary role of solder mask dams is to prevent solder from creating unintended connections between pads or traces. During the soldering process, when molten solder is applied to the PCB, it can sometimes spread beyond the desired area. A solder mask dam prevents this by creating a physical barrier.

Prevention of solder bridges

Solder mask dams help prevent solder from flowing into unintended areas, reducing the risk of solder bridges and electrical shorts.

Improve precision in soldering

By controlling where solder can flow, solder mask dams ensure that solder is applied only to the intended pads and through-holes.

Protection against oxidation and contamination

Solder mask dams shield underlying copper traces from oxidation and contamination.

Improved design flexibility

Solder mask dams allow for greater flexibility in PCB design by accommodating various component layouts and soldering techniques.

Cleaner soldering process

By preventing solder from spreading to adjacent conductive features, solder mask dams contribute to a cleaner soldering process, resulting in fewer defects and a more polished final product.

How Solder Mask Dams Work?

The solder mask dam works by setting specific isolation strips on the printed circuit board (PCB) to prevent short circuits in the pins of the SMD components. The solder mask covers the part of the PCB that does not need to be welded, and the exposed part is the copper sheet that needs to be welded. The solder stop layer is set to follow the principle of negative output, that is, after the shape of the solder mask layer is mapped to the PCB, the exposed is actually copper, rather than the part with green oil. This design helps ensure the accuracy of the welding and the stability of the circuit.

In reflow welding process, solder mask layer is very important to control welding defects. The designer should minimize the spacing or air gap around the pad features to avoid the formation of tin Bridges. For closely spaced components, such as QFPS on four sides, the openings or Windows of the solder shield may require special consideration in order to facilitate control of the tin bridge between the element pins. In addition, the thickness of the solder mask is also an important factor, if the thickness is more than 0.04mm, it may affect the application of the solder paste.

Solder mask materials can be used by liquid wet process or dry film lamination. Dry film solder resistance materials are usually available in a thickness of 0.07-0.1mm and are suitable for some surface mount products, but are less recommended for close pitch applications. Liquid photoresist materials are often specified for surface mount applications due to their economy and accuracy.

What is the Minimum Solder Mask Dam?

The minimum width of a solder mask dam depends on the design rules of the PCB manufacturer and the capabilities of the solder mask material. Typically, the minimum solder mask dam width ranges from 6 to 8 mils. In high-density designs, where components are packed closely together, achieving a consistent and effective solder mask dam at the minimum width can be challenging. Here is the PCB manufacturing capability in Best Technology of FR4 PCB:

How Thick Should Solder Mask Be in PCB?

The thickness of the solder mask plays a crucial role in its effectiveness. Standard solder mask thickness is usually between 15 to 25 microns. This thickness provides adequate protection against solder bridging while allowing the mask to withstand the heat and pressure of the soldering process. If the solder mask is too thin, it may not provide sufficient protection, leading to solder bleed. Conversely, if it’s too thick, it can cause misalignment issues during the assembly process.

How to Design a Solder Mask Dam?

Designing an effective solder mask dam requires careful planning and attention to detail. Here are key steps to follow when designing a solder mask dam:

1. Evaluate Component Density: Start by assessing the layout of your PCB. For high-density boards, you’ll need to design thinner dams that still provide sufficient protection.

2. Check Manufacturer’s Guidelines: Manufacturers have specific design rules for solder mask dams. It’s important to consult these guidelines to ensure your design meets the minimum and maximum dam widths allowed.

3. Optimize Pad and Trace Spacing: Ensure that there’s enough spacing between pads and traces to accommodate the solder mask dam. The spacing should be consistent to prevent solder bridges.

4. Simulate Solder Flow: Use simulation tools to visualize how the solder will flow during the assembly process. This helps identify areas where the solder mask dam may need to be adjusted for optimal performance.

5. Review Tolerance Requirements: PCB manufacturing involves tight tolerances. Make sure your solder mask dam design accounts for potential variations during fabrication.

What is the capacity of a circuit?

The capacity of a circuit, often referred to as PCB current-carrying capacity, is the maximum amount of electrical current it can handle without overheating or causing a fault. This capacity is crucial for ensuring that the circuit operates safely, powering all connected devices without causing damage. A circuit’s capacity is typically measured in amperes (amps), which shows the flow of electrical current. The capacity of a circuit is determined by its components, such as the wire size, the circuit breaker, and the connected devices.

Circuits need to be designed and maintained within their safe capacity. If you overload a circuit, it could lead to overheating, equipment failure, or even an electrical fire. The circuit breaker is the main defense against this, as it cuts off the current flow if the circuit exceeds its capacity.

How can an electrician predict a circuit’s capacity?

Electricians can predict a circuit’s capacity by analyzing the components of the electrical system. The wire gauge, breaker rating, and the types of devices connected to the circuit are all factors in this determination. The wire gauge (or thickness) is one of the most important factors—thicker wires can carry more current.

Another key element is the circuit breaker or fuse. These devices are rated for a specific current. For example, a typical household circuit breaker may be rated for 15 or 20 amps. Electricians calculate the expected load, considering how many devices are likely to run on that circuit at the same time.

To predict the capacity accurately, electricians follow safety codes and standards like the National Electrical Code (NEC). This ensures that the circuits can handle the loads without risks of overload.

What determines the size of a circuit?

The size of the circuit is mainly determined by the supply voltage and resistance. ‌

The size of the current is affected by a number of factors, of which the power supply voltage and resistance are the most direct and critical factors. The power supply voltage directly determines the driving force of the electron flow in the circuit, and the resistance is the obstacle of the electron flow, and the two work together to determine the size of the current in the circuit. To be specific:

‌Power supply voltage

The power supply voltage directly affects the size of the current. According to Ohm’s law, current is proportional to voltage. This means that the higher the voltage, the greater the current in the circuit.

‌Resistance size

The larger the resistance, the less current passes through the circuit. According to Ohm’s law, current is inversely proportional to resistance. This means that the greater the resistance, the smaller the current in the circuit.

In addition, the series-parallel relationship of the circuit and the temperature also affect the size of the current. In a series circuit, the total current is equal to the sum of the currents of each resistor; In a parallel circuit, the total current is also the sum of the individual resistance currents. A change in temperature will affect the value of the resistance and thus the magnitude of the current.

What is the making capacity of the circuit?

The making capacity of a circuit refers to the ability of a breaker or switch to handle the initial surge of current when it is first energized. This initial surge, often called inrush current, can be much higher than the normal operating current. The making capacity is crucial because it ensures that the breaker can handle this brief spike without tripping unnecessarily.

In industrial applications, the making capacity is even more important, as many machines and motors draw a high inrush current when starting up. The breaker must be able to manage this surge without interrupting the power flow. Typically, the making capacity is higher than the breaker’s rated current capacity to account for these surges.

What determines circuit capacity?

The factors that determine the capacity of a circuit mainly include the structure of the capacitor itself, environmental conditions, and application scenarios. The structure of the capacitor is a key factor in determining its capacity, specifically including:

Distance between the plates

The smaller the distance between the plates, the greater the capacitance. This is because reducing the distance increases the electric field strength, allowing the capacitor to store more charge.

Relative area of the plates

The larger the relative area of the plates, the greater the capacitance. A larger area makes the electric field more uniform, thus increasing the capacitor’s capacitance.

Dielectric constant of the insulating material

The higher the dielectric constant of the insulating material, the greater the capacitance of the capacitor. The dielectric constant reflects the material’s ability to influence the electric field, affecting the capacitor’s capacitance.

Material of the metal plates

The material of the metal plates also affects the capacitance. Factors such as the purity and conductivity of the metal can influence the capacity. Higher purity and better conductivity in the metal plates can increase the electric field strength, thus enhancing the capacitor’s capacitance.

Environmental conditions and application scenarios can also affect the circuit’s capacity, including:

Ambient temperature

Changes in ambient temperature can affect the resistivity of the metal plates and insulating material, which in turn affects the capacitance. An increase in temperature typically lowers resistivity, which may either increase or decrease capacitance, depending on how temperature influences resistivity.

Load resistance

In practical applications, when the capacitor works together with load resistance, the size of the load resistance affects the capacitor’s charging and discharging process, thereby influencing its capacitance. The size of the load resistance determines the speed at which the capacitor stores and releases charge, thus impacting the capacitor’s performance.

How do you calculate circuit load capacity?

To calculate circuit load capacity, electricians follow a few simple steps. First, they determine the total wattage of all the devices on the circuit. For example, a room may have several light bulbs, a television, and a computer, each with their own wattage rating.

Once they have the total wattage, they divide this by the voltage (typically 120V in homes). This gives them the total current in amps that the circuit is using. Electricians then compare this value to the circuit breaker’s rating. For safety, the total load should not exceed 80% of the breaker’s capacity. So, on a 20-amp circuit, the maximum continuous load would be 16 amps.

What is the maximum load on a 20-amp breaker?

A standard 20-amp breaker can handle up to 2,400 watts, based on a 120V system (20 amps x 120 volts = 2,400 watts). However, the NEC recommends only using 80% of the breaker’s capacity for continuous loads. That means a 20-amp breaker should typically handle no more than 1,920 watts (80% of 2,400 watts) for ongoing use.

This buffer is important because many appliances and devices draw more power when they first turn on, especially if they have motors or heating elements. By keeping the load below 80%, you avoid overloading the circuit.

In practical terms, a 20-amp breaker is commonly used for kitchen appliances like microwaves, toasters, or coffee makers. It’s also used in rooms where many devices might be connected, like living rooms or offices. By calculating the load and making sure it stays below the maximum, you can safely use your circuit without causing it to trip.

What is Resistance in a Circuit Board?

Resistance in a circuit board determines how easily electric current flows through the board. Every component and trace on the board offers some resistance, but the goal is to minimize it. Resistance happens when the flow of electrons is blocked or slowed down by the material they travel through. This blockage causes energy loss, often as heat.

In printed circuit boards (PCBs), low resistance is preferred in traces and paths to ensure smooth current flow. However, resistors are intentionally added in circuits to control and manage current flow, protecting sensitive components.

Does A Circuit Board Base Have Low Resistance?

What is the Base of a Circuit Board?

The base of a circuit board is the foundation on which components are mounted and connected. The copper layers, laminated onto the base, provide the conductive pathways that allow current to flow between components. It usually consists of layers of different materials, including a non-conductive substrate like fiberglass, often referred to as FR4. Some other materials also can be used as the base of circuit board, like:

Glass fiber cloth substrate: commonly used in the production of double panels and multi-layer boards, with good mechanical properties and cost effectiveness.

Paper substrate: lower cost suitable for cost-sensitive applications.

Epoxy resin substrate: it has good mechanical properties and thermal stability, widely used in electronic products

Polyimide substrate: it has excellent high temperature resistance, suitable for high performance electronic products.

Polytetrafluoroethylene (PTFE) substrate: very high temperature resistance and low dielectric constant, suitable for high frequency and high temperature environments.

Ceramic substrates: such as alumina, aluminum nitride, etc., with high thermal stability and low dielectric constant, suitable for extreme environments.

Teflon (ETFE) substrate, it has good corrosion resistance, high frequency properties and low dielectric constant.

Metal substrates: metal materials like aluminum or copper are always serve as the base of metal core PCBs, they have very good thermal conductivity, and suitable for high power applications where need good heat dissipation.

How Does a Basic Circuit Board Work?

The basic circuit board connects various electronic components through conductive paths called traces, and performs specific functions through the interaction of electronic components. These tracks are made of copper and are designed to create specific circuits that control the flow of electricity. The circuit board uses insulating materials to isolate the conductive layer of copper foil on the surface, so that the current flows in each component along the pre-designed path to complete the functions of work, amplification, attenuation, modulation, demodulation, coding and so on.

Components such as capacitors, resistors, transistors, and diodes are soldered onto the board. The current flows through the components, following the paths designed in the layout, executing the required tasks, such as powering an LED or processing signals.

For the circuit to work, all components must be properly connected and powered. Any break in these connections can disrupt the flow of current, leading to malfunctions.

The main components and functions of the circuit board:

Pad – metal holes for welding the pins of components.

Through hole – there are metal through holes and non-metal through holes, used to connect the component pins between each layer.

Conductor – the conductive path connecting electronic components.

Components – such as resistors, capacitors, inductors, etc., are connected to each other by conducting lines.

Connector – used to connect external devices.

Electrical boundary – defines the electrical characteristics of the board.

Does an Open Circuit Have Low Resistance?

No, an open circuit has high resistance, often considered infinite.

Open circuit refers to the circuit state when no current passes between two points in the circuit or is connected by a conductor with a very large impedance value (or resistance value). When the branch between two points in the circuit is open, the potential difference between the two points is called “open voltage” and can be measured by a voltmeter. In the open state, because there is no current flow, the resistance is very high, this is because the current path in the open circuit is interrupted, resulting in the current cannot flow, so that the resistance in the open state is extremely high ‌

In contrast, a short circuit refers to the situation where the current does not pass through the electrical appliance and directly constitutes a path. In a short circuit, the resistance in the circuit is small, because the current flows directly through the wire, rather than through the load, resulting in a large current. In this state, the fuse may automatically blow due to excessive current, to prevent the wire from causing a fire due to heat ‌

How to Tell If a Circuit Board is Shorted?

Identifying a shorted circuit board involves looking for signs like:

Burn marks or discoloration on the board.

Swollen or damaged components.

Overheating, causing the board to feel hot to the touch.

The device or board not powering on or malfunctioning.

To confirm a short, a multimeter can be used. By measuring the resistance between points where there should be separation, a very low resistance could indicate a short. This can help pinpoint faulty components or traces.

How to Check Resistors on a Circuit Board?

To check resistors on a circuit board, you can use a multimeter in resistance mode.

Turn off the power to the board and discharge capacitors to avoid any residual current.

Set the multimeter to the appropriate resistance range.

Place the probes across the resistor’s terminals and read the value displayed on the meter.

Compare this value with the expected resistance value, usually printed on the resistor or found in the circuit’s schematic. A large discrepancy could indicate a faulty resistor.

How Are Circuit Boards Grounded?

Circuit boards are grounded by connecting the ground plane, often a large layer of copper, to a grounding point. The grounding modes of the circuit board mainly include single point grounding, multi-point grounding, floating ground and virtual ground. ‌

Single-point grounding

Single-point grounding ‌ is suitable for low-frequency circuits where only one physical point in the entire circuit system is defined as the grounding reference point and all other points that need to be grounded are directly connected to this point. This approach can reduce common ground impedance coupling and low-frequency ground loop interference, and is usually used for circuits with frequencies less than 1MHz.

Multi-point grounding

Multipoint grounding ‌ is suitable for high-frequency circuits, where each ground point of the electronic device is directly connected to the nearest ground plane (that is, the metal base plate of the device). This method can reduce the interference generated by the common ground impedance, and also reduce the parasitic capacitance and inductance, which is usually used for circuits with frequencies greater than 10MHz.

Floating ground

‌Floating ‌ that is, the ground of the circuit is connected to the ground without a conductor, but at a higher potential. The advantage of floating ground is that the circuit is not affected by geoelectrical properties, and can prevent electromagnetic interference caused by the coupling of common ground impedance circuits. However, the disadvantage of this method is that it is affected by the parasitic capacitance, which leads to the change of ground potential and increases the inductive interference to the analog circuit.

Virtual ground

Virtual ground ‌ is similar to floating ground and can be understood as the “floating ground” when the operational amplifier is short and broken.

What is the Rule for Resistance in a Circuit?

The fundamental rule of resistance is governed by Ohm’s Law: V=IR, where voltage (V) is equal to the current (I) multiplied by resistance (R). This shows that the resistance directly affects how much current flows for a given voltage.

In circuits, resistors are used to control current, and their value determines how much current is allowed through. For example, higher resistance lowers the current flow, while lower resistance allows more current to pass.

PCB Full Form

PCB stands for Printed Circuit Board, a key component in almost all electronic devices. It connects and supports electronic components using conductive tracks, pads, and other features. The design and production of PCBs require precise engineering, as they are crucial for the functionality of the final product.

What is PCB Quote Packaging?

PCB quote packaging refers to the process of gathering and organizing all the details needed to estimate the cost of producing a PCB. This includes not only the design specifications but also the materials, manufacturing processes, and other engineering considerations. It’s not just a financial calculation but a complete engineering analysis that ensures the quote is accurate, feasible, and optimized for production.

The quote must consider every detail that affects production—like material types, size, complexity, and production volume. The aim is to package all these details into a clear, comprehensive quote, ensuring the client understands what they are paying for and why.

Why is Engineering Important in PCB Quote Packaging?

Engineering plays a vital role in the PCB quoting process because it’s not just about estimating costs. It’s about understanding the technical requirements and ensuring that every aspect of the design and production is accounted for. Engineers analyze the design, materials, and manufacturing methods to ensure the quote reflects the real cost of production.

Without engineering insight, a quote could be inaccurate, leading to cost overruns or production delays. Engineers make sure that all technical details, such as layer count, trace width, and component placement, are properly considered.

What Are the Key Factors in a PCB Quote?

Several factors come into play when preparing a PCB quote:

PCB Quote Packaging is What Type of Engineering?

1. Type of manufacturing process

The technical type of PCB determines its complexity and cost. For example, simple single panels cost much less than multi-layer panels, while flexible circuits (FPC) or rigid and flexible panels require more complex manufacturing processes and naturally cost more. In addition, whether advanced technologies such as microvias, laser drilling, blind holes or buried holes are required can also have a significant impact on the quotation.

2. Material type

Materials are an important part of PCB costs. Common materials include FR4, ceramics, metal substrates, etc. FR4 is the most common base material and is suitable for most conventional applications, but for high-frequency, high-temperature environments, ceramic or metal-based materials may be more suitable, but their price is relatively high. Choosing the right material not only affects the performance, but also directly affects the cost.

3. IPC level

IPC grades reflect the quality standards of PCB manufacturing, commonly used are IPC-A-600 grades 1, 2 and 3. The higher the grade, the more stringent the manufacturing requirements, and the corresponding increase in cost. For example, grade 3 PCBS are usually used in high-demand fields such as aerospace and medical equipment, which require higher accuracy and quality control, so the price is higher.

4. Circuit design

PCB circuit design complexity directly affects manufacturing costs. Including wire width, spacing, hole size and so on, the production process has put forward different requirements. High density interconnect (HDI) boards typically require more elaborate wiring techniques and may involve the use of microvias, which will increase the difficulty and cost of manufacturing.

5. PCB size and yield

The size of the PCB directly affects the amount of material used, and the larger the board, the more material is needed. In addition, the yield is also an important factor affecting the quotation. PCB manufacturing with complex design or high density lines is prone to defects, resulting in decreased yield. That means manufacturers may need to produce more boards to meet orders, increasing costs.

6. Material thickness

Different applications require different thicknesses of PCB materials. The standard FR4 thickness is usually 1.6mm, but thinner or thicker boards are sometimes used. Changes in material thickness can affect the overall cost, especially if thicker sheets require special processing or higher strength, and manufacturing expenses will increase accordingly.

7. Copper thickness

The copper thickness in the PCB usually has a standard choice, such as 1oz, 2oz or even thicker copper layers. The higher the copper thickness, the better the conductivity of the PCB, suitable for high-current applications, but the increase in copper thickness will significantly increase the manufacturing cost, especially in the plating and etching process requires additional materials and processes.

8. Stack-up method

The stacking mode determines the number of layers and the interlayer structure of the PCB. Complex multilayer boards or HDI boards require more complex lamination processes. For example, the lamination method may involve multiple pressing, the use of prepregs or special insulation materials. Each additional layer requires more manufacturing steps, resulting in increased costs.

9. Quantity

The quantity of the order has a direct impact on the PCB quotation. High-volume production can reduce unit prices by spreading tooling and setup costs, while small-batch orders are typically more expensive due to relatively high production preparation and start-up costs.

10. Delivery date

The shorter the delivery time, the higher the quotation. Rush orders require prioritizing production, which can disrupt the plant’s production schedule and require additional resource deployment. To meet urgent delivery deadlines, manufacturers may need to work overtime or speed up production, increasing overall production costs.

These are just a few examples, but they show how engineering considerations are woven into every part of the quoting process.

PCB Manufacturing Process

How Do Engineers Calculate PCB Manufacturing Costs?

Engineers calculate PCB manufacturing costs by considering the design specifications and the production methods needed to meet those requirements. They start by analyzing the PCB’s layout and design, which determines factors like layer count, trace width, and hole size. Each of these elements has a direct impact on the materials used and the manufacturing process.

They also consider the assembly process—whether it’s surface-mount or through-hole—and what testing will be required. After evaluating these details, they calculate the costs associated with each step of the manufacturing process. This ensures the final quote is both accurate and comprehensive.

What Type of Engineer Designs PCBs?

Engineers who design PCBs typically have a bachelor’s degree or above in electrical engineering, automation, computer science, or a related field ‌ and understand the basics of electronic design, printed circuit board (PCB), and electronics manufacturing in the PCB industry. These engineers need to master PCB design software such as Altium Designer, Eagle PCB, PADS, or CAD, etc., as well as the use of related manufacturing and testing tools. At the same time, they need to have a knowledge of the PCB industry, a certain circuit design and electronic components knowledge, including digital and analog circuits, signal processing, power electronics, embedded systems, communication technology, etc. In addition, holding certificates such as IPC-2221/2222, IPC-A-600/610, and CID (Certified Interconnect Designer) can prove that they have relevant professional knowledge and skills, which can help improve their career competitiveness.

These engineers also need to have a strong sense of responsibility and team spirit, have good communication and coordination skills, and be able to work effectively with customers, manufacturers, and other team members. For junior engineers, it is recommended to study in a single point of depth, such as PCB design, SI simulation, thermal design, EMC design, product testing, etc., and then start from this advantage point to expand the scope of knowledge

What Materials Are Considered During PCB Quote Packaging?

The type of material used for a PCB is a major cost driver. Common materials include:

This is the most common material used in PCBs due to its balance of cost and performance. It’s versatile and reliable for most standard applications.

Metal Core

Metal core PCBs are used in applications where heat dissipation is a concern, such as LED lighting. These boards are more expensive due to the metal layer.

Ceramic

Ceramic materials are used for high-frequency or high-temperature applications. They are more costly but offer better performance in extreme conditions.

Each material has its own manufacturing process, which also affects the cost. For instance, metal core boards may require different drilling techniques compared to standard FR4 boards. Engineers must consider these details when preparing a quote.

How Does the Choice of PCB Manufacturing Methods Impact the Quote?

The method used to manufacture the PCB can greatly impact the final cost. Common methods include:

Surface-Mount Technology (SMT): This is the most common method for modern PCB assembly. It’s efficient and cost-effective for most applications.

Through-Hole Technology (THT): This method is used for components that require a stronger mechanical bond. It’s more labor-intensive and, therefore, more expensive.

Flexible and Rigid-Flex Manufacturing: These types of PCBs require specialized processes and materials, which can increase the cost.

Additionally, advanced techniques like laser drilling for microvias or selective soldering for complex assemblies may be necessary for high-precision designs. Each of these methods requires careful consideration, and engineers must choose the best process for both the design and the budget.

Why are PCBs 1.6mm Thick?

The 1.6mm thickness has become the standard for most PCBs. But why is this the preferred thickness? One reason is historical—it was a size that worked well for manufacturing processes when PCBs were first developed. Over time, this became the norm due to its balance between durability and flexibility.

From the perspective of process and cost, the thinner the PCB board, the higher the manufacturing cost. Because it is necessary to use higher levels of materials and more refined processes to meet the various requirements of PCB boards in the manufacturing process. At the same time, PCB boards that are too thin are also susceptible to environmental and mechanical forces and have poor stability. Therefore, under the premise of taking into account cost and stability, 1.6mm has become a more common PCB board thickness.

Secondly, from the perspective of compatibility and standardization, in the vacuum tube era, because the development and manufacturing of PCB substrates have not yet achieved industrial production, PCB board thickness is mainly determined according to the equipment housing/installation hardware or the required PCB board thickness. At that time, the 1.6mm specification gradually became the industry standard and provided compatibility and convenience for later PCB manufacturing and design.

In addition to 1.6mm, there are some other common PCB board thickness, such as 0.8mm, 1.0mm, 1.2mm, 2.0mm and so on. These thicknesses are usually selected based on specific application and design requirements.

For example, in the field of communications, the commonly used PCB board thickness is generally 0.8mm; In the field of consumer electronics, the commonly used PCB board thickness is generally 1.0mm. In addition, for some specific applications, you can also choose other non-standard thickness options, such as 0.4mm, 0.6mm, 2.4mm, etc.

How Thick is a 1.2mm PCB?

Compared to the standard 1.6mm, a 1.2mm PCB is thinner, which makes it ideal for compact designs where space is at a premium. The 1.2mm thickness reduces the overall weight of the PCB, which can be critical in devices like smartphones, wearables, and other portable gadgets.

Despite being thinner, 1.2mm PCBs can still provide good mechanical support and electrical performance, though they might not be as resistant to bending or mechanical stress as their thicker counterparts. This makes them better suited for applications that do not require heavy-duty handling or exposure to harsh environments.

1.2mm vs. 1.6mm PCB

So, how do you decide between a 1.2mm and a 1.6mm PCB? It depends on the specific needs of your project. Here are some factors to consider:

Mechanical Strength

A 1.6mm PCB is more rigid and can withstand greater mechanical stress, making it ideal for larger devices or environments where the board may face pressure or force. If your design requires a sturdy board, 1.6mm is a better option.

Compact Design

For smaller, more compact devices, a 1.2mm PCB can save valuable space and reduce the overall profile. This is especially important for handheld gadgets or portable electronics where size and weight matter.

Thermal Management

Thicker boards like the 1.6mm version have better thermal management properties, as they can dissipate heat more efficiently. If your PCB will handle high power or generate a lot of heat, the 1.6mm option may be a better fit.

Cost

While the difference in cost between 1.2mm and 1.6mm PCBs is usually minimal, thinner boards might be slightly more cost-effective, especially for large-volume production. However, always weigh this against the performance needs of your application.

Ultimately, the decision comes down to the balance between durability, size, and the operating environment of your product.

Is Thinner PCB Better?

A thinner PCB, like the 1.2mm version, can be better in certain applications, but it’s not universally superior. The key benefit is the reduced thickness, which translates to lighter and more compact products. This is why thinner PCBs are favored in modern consumer electronics where every millimeter counts.

However, thinner PCBs are less rigid, making them more prone to bending or warping under pressure. If the PCB is subjected to mechanical stress or has to endure rough handling, a 1.6mm thickness might be the safer choice.

For low-stress applications, such as small gadgets or tightly packed devices, a 1.2mm PCB can offer the perfect balance of performance and size. The goal is to match the thickness to the demands of your specific project.

What is the Tolerance of a 1.6mm PCB?

PCB manufacturers often specify tolerances to account for minor variations in thickness during production. For a 1.6mm PCB, the typical tolerance range is around ±0.10mm, though this can vary based on the manufacturer and specific requirements of the project.

Tolerances are crucial in ensuring that the PCB fits within the required mechanical constraints of the final product. When designing a product, it’s essential to account for this tolerance, especially if your design requires exact thickness dimensions.

The tolerance of a 1.6mm PCB helps ensure consistent performance, even with minor deviations in the manufacturing process.

How Thick is a Standard 2-Layer PCB?

A standard 2-layer PCB typically ranges from 1.6mm to 2.4mm in thickness. However, 1.6mm is the most common thickness for 2-layer boards used in a wide range of applications.

The two layers refer to the copper traces that are used for electrical connections, and the thickness of the board itself determines its strength, thermal properties, and overall performance. In most cases, a 1.6mm thickness offers an ideal balance for general use, providing both durability and flexibility in terms of design and assembly.

How to Choose a Suitable PCB Thickness?

When choosing the thickness of a PCB, several factors need to be considered:

1. Weight

Weight is a key factor. Thinner boards tend to be more fragile and are more likely to break. Therefore, if lightweight is not a strict requirement, thicker boards are usually the better choice.

2. Flexibility

Flexibility is another important consideration. Thinner boards are generally more flexible, but they are also more prone to breaking. Thicker boards offer less flexibility but provide greater stability.

3. Space

The amount of space available in your device is crucial when deciding on PCB thickness. If your device has enough room to accommodate a thicker PCB, then using a thicker board is advisable. On the other hand, if the device is compact, a thinner PCB may be necessary to fit into the available space.

4. Type of Connectors and Components

The type of connectors and components you plan to use also influences the PCB thickness. Different components may have specific requirements that determine the board’s thickness.

5. Dimensions and Design

When selecting PCB thickness, factors such as the dimensions of the PCB, the number of layers, the weight of the installed components, the installation method, and impedance should all be considered. A general rule of thumb is: when the aspect ratio of the PCB (length to width) is not greater than 2 and the width-to-thickness ratio is not greater than 150, the performance is optimal. The width here refers to the smaller dimension between the depth or height of the PCB.

For plug-in boards mounted in vertical boxes, the thickness should fully consider deformation issues. For PCBs that are not box-mounted, if the size is smaller than 300mm x 250mm, 1.6mm to 2mm thick boards are preferred. Larger PCBs should use 2mm, 2.4mm, 3mm, 3.2mm, 3.5mm, or even thicker boards, but it is best to avoid exceeding 4mm.

6. Copper Thickness, Layers, and Signal Type

When determining the PCB thickness, you should also factor in the copper thickness, the material of the board, the number of PCB layers, the types of signals it will carry, and the type of through-holes being used. The operating environment is another key consideration.

PCB Manufacturing Considerations

Several manufacturing factors also influence the final PCB thickness:

Drilling equipment capability

Copper thickness

Number of layers

Board cutting method

For non-standard thickness PCB designs, additional factors include:

1. Manufacturer Capability

The first consideration is whether your PCB manufacturer has the equipment and capability to produce the specific thickness you need. This decision should be made early in the design process, along with other Design for Manufacturing (DFM) requirements. Otherwise, you may need to make changes and redesign your PCB stack-up.

2. Extended Delivery Time

If your manufacturer does not stock the materials required for non-standard thickness, it could delay the production timeline. Therefore, it’s essential to consider the delivery time when choosing a non-standard thickness.

3. Additional Costs

This is perhaps the most important point: you need to evaluate the cost of special materials, additional manufacturing costs, and the potential impact of delayed delivery to determine if the extra expenses are justifiable.

Opting for standard PCB thicknesses typically results in faster production and lower costs. However, if you decide on a non-standard thickness, it’s crucial to communicate with your manufacturer early in the design phase. This ensures that they can meet your requirements, and you’ll also need to clarify lead times and any additional manufacturing costs.

FAQs

Q1: Can I customize the thickness of my PCB?

Yes, many manufacturers offer custom thickness options ranging from thinner boards like 0.8mm to thicker boards over 2.4mm, depending on your needs.

Q2: What are the benefits of a 1.2mm PCB?

A 1.2mm PCB offers space-saving advantages, making it ideal for compact devices like smartphones and wearables. It also tends to be lighter.

Q3: Will a 1.2mm PCB be more flexible?

Yes, thinner PCBs are more flexible, which may be useful in specific applications where slight bending is acceptable.

Q4: Why is thermal management important in PCB design?

Proper thermal management prevents overheating and ensures the long-term reliability of the PCB, especially in high-power applications.

Q5: What is the standard thickness tolerance for a PCB?

The standard tolerance is usually around ±0.10mm, but this can vary depending on the manufacturer and board specifications.

What is Copper Pour in PCB Design?

Copper pour, also known as copper coating, refers to filled solid copper on PCB where without trace layout area or idle space. Instead of leaving unused areas bare, copper is poured over them, connecting it to the ground or other designated signals. The main purpose of this process is to reduce the ground impedance, improve the anti-interference ability, reduce the voltage drop. Thereby improving the power supply efficiency, and connect with the ground wire to reduce the loop area. By covering large sections of the board with copper, it also minimizes signal interference and adds a layer of protection to the PCB. Copper pour are essential for designers to maintain signal integrity and reduce unwanted noise.

What is Pour Board? What is Copper Pour in PCB?

The process of copper coating is not only very important for digital circuits, because it can effectively reduce the ground impedance, which is particularly important for digital circuits with a large number of spiking pulse currents. However, for analog circuits, the ground wire loop formed by laying copper may cause electromagnetic coupling interference.

Why Use Copper Pours on Circuit Boards?

Copper pours offer several advantages that make them an essential part of circuit board design. When creating PCBs, some engineers tend to leave many copper-free areas on the board. But a high percentage of copper-free areas on the PCB can negatively affect the product, making it vulnerable to early damage, when copper pouring comes in handy.

There are some novices who think that less copper pouring means that the cost will be lower and lower, which is wrong. It is true that the plating area is small, which can save copper, but there is no way to guarantee the quality, and the appropriate amount of copper pouring can improve the quality of the product.

When the PCB board is placed in the plating tank and the appropriate current is applied, the PCB will show the physical state after dry film coverage. After passing a current, the circuit lines exposed to the outside of the dry film will be plated with copper from the plating tank. The total area of the part of the circuit exposed outside the dry film will affect the value of the current distribution during the plating process, if the bare copper area is large, the current input is uniform, and the current received is more uniform. Therefore, a large area of copper plane must be laid in the design to prevent this from happening. If the total plating area of copper is too small or the pattern distribution is very uneven, the received current will not be uniform. In this way, when powered on, the greater the current, the thicker the copper plating layer (so designed, if only 1OZ is required, then the finished copper thickness can reach 2OZ).

If the gap between current traces is too small, for example about 3mil to 3.5mil, a “clip film” will form between the traces. In other words, the dry film is caught in the middle of the gap, which causes the subsequent base to start the copper in the middle, which can lead to a short circuit if the etching process is not cleaned. In order to maintain the high quality of PCB manufacturing, independent lines must be avoided as much as possible in PCB design and layout. In addition, it is recommended to use a large amount of copper on the entire PCB, if there is a separate line that cannot be covered with copper, then the continuation between the lines must be as wide as possible.

Advantages of Copper Pour Board

1. For EMC (electromagnetic compatibility) requirements, a large area of ground or power supply needs to be covered with copper, which will play a shielding role. For some special area, such as protective ground, it plays a protective role.

2. From PCB manufacturing perspective, generally in order to ensure an uniform copper plating, or avoid lamination deformation and bending, manufacturers always pour copper for those less trace layout PCB board.

3. For signal integrity PCB, pour copper gives the high-frequency digital signal a complete return path, and reduce the wiring of the DC network. In another way, pour copper can help to heat dissipation.

Disadvantages of Copper Pour

1. If the pins of the components are fully covered with copper, the heat dissipation may be too fast, resulting in difficulties in dismantling and repairing the components. Therefore, sometimes in order to avoid this situation, cross connections are used for components (pin contact and pad contact are shown in “+”).

2. Pouring copper in the area around the antenna is easy to cause weak signal, interfered acquisition signal, and the impedance of copper will affect the performance of the amplifier circuit. So the area around the antenna section is usually not covered with copper.

Copper Pour vs Ground Plane

There’s often confusion between copper pours and ground planes. While both serve similar purposes, they are not the same. A ground plane is a layer dedicated entirely to the ground signal, covering the entire surface of a board layer. It ensures a low-impedance path for electrical signals, minimizing interference.

Copper pours, on the other hand, are not necessarily tied to the ground. Designers can connect copper pours to any net, including power lines or signal traces. The primary goal of a copper pour is to fill in empty spaces, whereas a ground plane is dedicated exclusively to providing a ground connection.

Implementation of PCB Copper Pours

When designing a PCB with copper pours, a few best practices help in optimizing its performance. Here are some useful tips:

Assign Copper Pours to Ground First

When designing, prioritize assigning continuous copper to ground layers over power planes. A solid ground plane improves overall performance, providing a reliable reference for signals and reducing noise. Every PCB should have strong, consistent ground connections.

Monitor Trace Currents

Although reducing inductance is advantageous, flooding the board with copper can sometimes interfere with circuit tuning. Be mindful of traced paths, especially in high-current areas, to maintain proper load control.

Maintain Symmetry in Copper Pours

Ensure copper pours are symmetrical on both sides of the PCB. This balance helps prevent issues like board warping due to uneven expansion or moisture absorption. Symmetrical copper distribution is essential for the board’s structural integrity.

Avoid Acute Angles

Keep copper pours free from long, narrow protrusions or angles sharper than 45 degrees. Such shapes can become weak points, breaking off or acting as antennas during vibration or shock, potentially causing functional failures.

Incorporate Relief Features

Adding slots, anti-pads, and thermal spokes can relieve stress caused by material expansion, especially for large copper pours used on power planes. These features ensure mechanical stability and ease soldering.

Carefully Review Design Masks

Automated copper pour shapes may need manual adjustments to remove artifacts or undesirable patterns around complex components. Always review and fine-tune these masks to achieve optimal results.

When copper pours are correctly connected to appropriate nets, designers can enhance both the electrical and physical properties of the circuit by distributing copper strategically across the board.

Copper Pour Clearances and Settings

When designing a PCB with copper pours, clearances and settings play a crucial role in ensuring proper functionality and avoiding issues like short circuits. Here are PCB copper pour suggestions based on standard PCB board:

1. Trace to Copper Pour Clearance

Standard clearance: 0.2 mm (200 µm) or 8 mils
High-voltage applications: 1 mm (1000 µm) or 40 mils (or more, depending on voltage levels)

2. Pad to Copper Pour Clearance

SMD pads: 0.2 mm to 0.3 mm (8-12 mils)
Through-hole pads: 0.3 mm to 0.5 mm (12-20 mils)

You can adjust these values based on the pad size and the net to which the copper pour is connected.

3. Copper Pour Width and Thickness

The width and thickness of the copper pour should be chosen based on the current-carrying capacity of the board:

Minimum width: 1.5 mm (60 mils) for low-current signals
Power lines: At least 2-3 mm (80-120 mils), depending on current
Copper thickness: 35 µm (1 oz/ft²) is standard, but for higher currents, you can use thicker copper like 70 µm (2 oz/ft²) or more.

4. Via Clearance in Copper Pours

Standard via clearance: 0.2 mm (8 mils)
High-current via clearance: 0.5 mm (20 mils)

Clearance should be adapted to the board’s layer stack-up and current needs.

5. Thermal Relief Spokes

Spoke width: 0.3 mm to 0.5 mm (12-20 mils)
Spoke count: Typically 4 thermal relief spokes per pad
Clearance to pad center: 0.5 mm (20 mils)

6. Copper Pour to Board Edge Clearance

Standard clearance: 0.5 mm (20 mils) from the board edge
High-voltage boards: 1 mm (40 mils) or more

Layer Placement of Copper Pours

Copper pours can be placed on any layer of a PCB. In multi-layer PCBs, copper pours are often added on internal layers to maximize performance. For example, ground and power pours are frequently found on internal layers to reduce noise and improve thermal dissipation.

On outer layers, copper pours serve to enhance thermal management. They distribute heat from high-power components and help maintain an even temperature across the board. It’s important to balance the placement of copper pours with other components to ensure overall board stability and functionality.

Copper Pour PCB Design Considerations

1. The open areas in the design must be minimized and the open Spaces filled with copper.

2. It’s important to assess the current-carrying capacity. Make sure the copper pour is thick enough to handle the expected current loads, especially in power applications.

3. If there is no room for the copper, the two wires, the two pads, and the distance between the wires and the pads are designed to be 2 ounces thick with a minimum spacing of 8 mil.

4. When pouring copper, keep a certain distance from the ordinary touch pad. The distance between the track, the common plane and the drilled area should be greater than 0.5 mm. The copper must be poured as firmly as possible. Avoid pouring copper on small grids.

5. The inner layer of the gold finger must be all poured copper to avoid thinning of the board at the gold finger. Avoid choosing laminated structures with thin plates.

6. Those thin long, poorly grounded ground copper will have an antenna effect, which will cause poor EMC problems. Therefore, we should try to avoid causing broken copper when coating copper, such as causing broken copper can be removed.

7. Isolated (dead zone) copper problem, isolated copper if relatively small equivalent to broken copper can be deleted. If it is large, it can be defined as a place to add through the hole treatment, at this time there is no isolated copper.

8. Refer to the product design manual and apply copper coating near the antenna. Any interference or interference with the antenna must be avoided when pouring fake copper.

What is pcba?

PCBA is the abbreviation of Printed Circuit Board Assembly, which means “circuit board assembly” or “circuit board assembly”. ‌It refers to installing electronic components on a printed circuit board and connecting the components to the circuit board through welding and other methods to form a complete circuit system.

This process involves multiple important links, including SMT (surface mount technology) mounting, DIP (dual in-line package) plug-in, etc., which eventually form a key component of electronic products.

What is pcba manufacturing

The manufacturing process of PCB (printed circuit board) involves multiple process links, including design, plate making, drilling, filling, electroplating, etc. These steps together constitute the manufacturing process of PCB.

Design: First, according to the needs and layout design of the circuit, the circuit diagram is drawn using computer-aided design (CAD) software. This stage is very critical because it directly determines the function and performance of the PCB.
Plate making: After the design is completed, the designed circuit diagram needs to be converted into a practical PCB board that can be made. This usually involves the use of photosensitive materials and special chemical treatments so that the circuit pattern can be accurately transferred to the PCB substrate.
Drilling: After the plate making is completed, holes need to be drilled on the substrate according to the designed circuit pattern. These holes are used for subsequent wiring connections. The precision and accuracy of drilling are essential to ensure the normal operation of the circuit.
Filling: After drilling, some substances, such as resin, need to be filled in the hole to enhance the structural strength and electrical insulation performance of the PCB.
‌Electroplated‌: In order to ensure good electrical connection, the PCB needs to be electroplated, usually by electroplating a layer of copper or other conductive materials on the copper foil. This step is very important to ensure the conductivity and durability of the circuit.
‌Lamination and cutting‌: After the electroplating is completed, the multi-layer circuit boards are laminated together to form a multi-layer PCB. Subsequently, the PCB boards are cut into specific sizes as needed.
Inspection and testing‌: The manufactured PCB is inspected and tested to ensure that its functions and performance meet the design requirements. This may include visual inspection, functional testing and other methods.

‌‌PCBA testing‌ is the process of testing the electrical conductivity and input-output values of the PCBA circuit board with mounted electronic components to ensure that all the installed circuit boards are completely consistent with the various specifications and parameters of the design. Through strict testing, the performance and reliability of the PCBA board can be improved, customer trust can be won, and cooperation between enterprises and customers can be promoted.

PCBA testing includes various test forms, such as ICT testing (internal circuit testing), FCT testing (functional testing), fatigue testing, extreme environment testing and aging testing.
ICT testing tests the characteristics of devices and circuit networks by applying test probes to the test points on the PCB.

FCT testing is mainly used to test the electronic and electrical functional aspects of the PCBA board, and is tested under the condition of simulating the actual operating state of the PCBA board. Fatigue testing performs high-frequency and long-term operations by sampling to observe whether failures occur.

Extreme environment testing places the PCBA board in harsh and extreme environments, such as high temperature, severe cold, and falling, to infer the reliability of the PCBA board. Aging testing is to power on the PCBA board and electronic products for a long time to observe whether any failures occur.

What is a pcba number

A combination of letters and numbers used to uniquely identify and track each electronic component on a circuit board. These numbers are often called component numbers, part numbers, or reference designators.

On PCBA boards, the format and meaning of these numbers may vary depending on the manufacturer and designer, but generally follow certain rules.

For example, common numbers are R107, C118, Q102, D202, etc., where:
The first letter usually identifies the type of device, such as: R for resistors, C for capacitors, D for diodes, Q for transistors, etc.
The subsequent digital part may indicate the circuit function number (such as “1” may indicate the motherboard circuit, “2” may indicate the power supply circuit, etc.) and the serial number of the device on the circuit board.

What are AC and DC?

1. Definition of alternating current and direct current:

Alternating current (AC) refers to the current whose direction changes periodically over time, and the average current in one cycle is zero.

The waveform of alternating current is usually a sine curve, but there can also be other waveforms, such as triangular waves and square waves. Alternating current is widely used in power transmission and industrial applications.

Inverters and converters? What effect do they have on current flow?

Direct current (DC) refers to the current whose direction is constant.

The magnitude and direction of direct current do not change with time. Common DC power sources include dry batteries and storage batteries. The direction of pulsating direct current does not change, but the magnitude changes with time. It usually needs to be filtered to become smooth direct current.

2. The difference between AC and DC:

The main difference between AC and DC is whether the direction of the current changes over time.

The direction of AC changes periodically, while the direction of DC remains unchanged. In addition, the average value of AC in a cycle is zero, while the current and voltage of DC remain constant.

3. Application scenarios of AC and DC:

AC is mainly used for power transmission and industrial applications because its waveform is a sinusoidal curve, which is suitable for long-distance transmission. DC is often used in situations where constant current is required, such as battery-powered electronic devices.

How do you convert from DC to AC?

DC can be converted into AC through an inverter. The inverter usually consists of an inverter bridge, control logic, and filter circuits.

Inversion is a current conversion process opposite to rectification, which converts DC into AC. When the inverter side, i.e., the AC side, is connected to the power grid, it is called active inversion, and when the inverter side, i.e., the AC side, is directly connected to the load, it is called passive inversion.

The inverter circuit can convert DC power into AC power of any frequency and voltage under the control of the control circuit, so it is widely used, for example, when DC power is needed to supply power to AC loads.

What is dc to ac inverter?

‌Inverter is a device that converts DC power into AC power. ‌‌

The inverter is mainly composed of an inverter bridge, control logic and filter circuit, which can convert DC power (such as batteries, storage batteries) into fixed frequency and voltage or frequency and voltage AC power, usually 220V, 50Hz sine wave.

Inverters are particularly widely used in automobiles. They can drive various electrical appliances and tools by connecting to batteries, making it possible to use household appliances when driving or traveling.

Inverters can be divided into sine wave inverters and square wave inverters according to the output waveform. Although the sine wave inverter is more expensive, it can be applied to various loads, and the output waveform is closer to the mains, which is friendly to electrical equipment.

The efficiency of the inverter is an important indicator of its performance, which indicates the ratio of output power to input power. With the development of technology, inverters are showing a trend of high frequency, high performance and miniaturization, and are widely used in various fields of power electronics technology.

What is dc to ac converter?

An AC to DC converter is a device whose main function is to convert alternating current (AC) into direct current (DC). Such converters are commonly used in household appliances, computers, mobile phone chargers and other devices to convert the AC power provided by the power grid into the DC power required by the device.

The working principle of the AC/DC converter involves converting the AC power into smooth DC power through a rectification and filtering process. This converter can be bidirectional in terms of power flow, that is, power can flow from the power source to the load (called rectification) or from the load back to the power source (called active inversion).

The working principle of the AC/DC converter involves several key steps:

‌Rectification‌: Converting AC power into unidirectional pulsating DC power is achieved by using a rectifier, which can be a half-wave rectifier or a full-wave rectifier, depending on the specific technology used.

‌Filtering‌: Filtering is performed by using capacitors to eliminate the pulsating components generated during the rectification process to obtain a smoother DC power.

‌Voltage stabilization‌: In some applications, voltage stabilization may also be required to ensure the stability of the output voltage.

The design and application of AC/DC converters are limited by many factors, including safety standards, electromagnetic compatibility (EMC) requirements, and power system optimization design.

In addition, the use of high-voltage, high-current switches increases the power consumption, which to a certain extent limits the modularization process of AC/DC converters.

What is the difference between an inverter and converter?

The main difference between an inverter and a converter is that they have different functions and conversion directions. ‌

Although inverters and converters sound similar, their functions and conversion directions are completely different. The main function of an inverter is to convert direct current (DC) into alternating current (AC), while a converter does the opposite, converting AC into DC. This difference makes them play their respective roles in different application scenarios.

1. ‌Inverter‌:

The main application of an inverter includes converting electricity generated by a DC power source (such as a battery) into AC to meet the needs of AC equipment. The advantages of the inverter include high conversion efficiency, fast startup, good safety performance, etc., but it may also generate noise due to its working principle, and corresponding countermeasures need to be taken to reduce the noise.

2. Converter:

Unlike the inverter, the main function of the converter is to convert AC to DC.

This is usually achieved through the process of half-wave rectification and full-wave rectification, which involves passing the positive half-cycle or positive and negative cycles of AC through the rectifier circuit, and then further processing through capacitor filtering and voltage stabilization circuit to finally obtain DC.

Converters are widely used in various electronic devices that need to convert AC power to DC power.

In general, although inverters and converters are similar in name, their functions and conversion directions are completely different. Inverters convert DC to AC and are suitable for using DC power for AC devices; while converters convert AC to DC to meet the needs of devices that require DC power.

Why would you use an inverter?

The main reason for using an inverter is to convert DC to AC to meet the power needs of various devices and systems. ‌

The main function of the inverter is to convert direct current (DC) into alternating current (AC), which is necessary in many fields and scenarios. Here are some of the main uses of the inverter:

2. Emergency power supply: In the event of a power outage or power outage, the inverter can convert the DC power of the backup power source (such as gasoline generators, solar panels, etc.) into AC power to provide power support for key equipment.

3. Electronic devices: Many portable electronic devices (such as laptops, mobile phones, cameras, etc.) use DC batteries as power sources. The inverter can convert DC power into AC power to provide power for these devices.

4. Industrial applications: In industrial production, the inverter can convert high-voltage DC power into low-voltage AC power to meet the power needs of different equipment and systems.

5. Electric vehicle charging: With the popularity of electric vehicles, inverters are increasingly used in electric vehicle charging stations, which convert direct current from the power grid into alternating current required by electric vehicle batteries.

6. Radio communication: In radio communication, inverters are used to convert direct current into radio frequency power to transmit and receive radio signals.

Therefore, inverters play an indispensable role in modern society and are widely used in various fields to provide necessary power conversion and support for various devices and systems.

What are the disadvantages of an inverter?

1. Harm to batteries: Inverters increase the burden on batteries and shorten the life of batteries. Inverters generate electromagnetic interference and heat when working, which may interfere with batteries, causing unstable battery voltage or internal damage to batteries.

2. Energy loss: The conversion efficiency of inverters is relatively low, and there will be a certain amount of energy loss.

3. High cost: The cost of inverters is high, which may not be suitable for some low-cost applications.

4. May generate electromagnetic interference and heat: The inverter will generate high-frequency electromagnetic waves and a certain amount of heat when working, which may affect the working performance of other electronic equipment and may even cause safety problems.

In summary, although the inverter provides convenience in many applications, its disadvantages cannot be ignored, including energy loss, high cost, possible electromagnetic interference and heat, and potential safety hazards.

Conclusion:

Inverters and converters are indispensable in modern electrical systems to ensure that energy flows to where it is needed in the right form. Whether it is converting DC to AC for renewable energy systems, using batteries to power equipment, or ensuring uninterruptible power supply, these tools can achieve a smooth transition between different types of current.
