With the development of society, the demand for heavy copper PCBs in different industries has become increasingly greater. At present, heavy copper PCBs have been widely used in various electronic industries. Generally speaking, heavy copper technology can realize complex switches in a limited space, combine circuits with high current levels, and is conducive to heat dissipation. Multilayer and double-sided are the most common designs we know. More importantly, heavy copper PCB technology makes it possible to combine good layout structures on the outer layer and Heavy copper layers on the inner layer.

What is a heavy copper PCB?

Heavy copper PCB is a special printed circuit board (PCB) characterized by a very high concentration of copper, usually up to 200 ounces per square foot, and the copper content of the inner and outer layers of the circuit board is above 3 ounces (oz), which enables heavy copper PCBs to conduct extremely high currents, achieve good heat distribution, and realize complex circuit layouts in a limited space.

In the design and manufacturing process of heavy copper PCBs, thermal stress handling is an important consideration. Engineers need to eliminate thermal stress as much as possible to maintain the circuit while minimizing the power budget, while taking into account environmentally friendly design.

With the development of PCB manufacturing process, modern manufacturing technology such as the use of aluminum PCB can better handle thermal stress problems.

The heat dissipation capacity of Heavy copper PCB is better than the traditional solution of using external heat sink, because it prints the heat sink directly on the circuit board during the manufacturing process, and achieves rapid heat transfer through conductive through-holes, thereby improving heat dissipation performance.

In general, Heavy copper PCB is a high-performance electronic component carrier, which provides an ideal solution for applications requiring high power and high reliability through its high copper content and optimized thermal management characteristics.

What is the difference between PCB and Heavy copper PCB?

Copper board and Heavy copper board look similar in name, and people tend to think that they are the same PCB, but in fact they refer to different things.

1. PCB:

PCB refers to a copper-based PCB. The use of copper as a substrate is to better dissipate heat and extend the life of components on the PCB. The copper substrate is to allow heat to be quickly transferred from the PCB to the outside, such as a heat sink or a metal casing. Because the thermal conductivity of copper is several times that of aluminum or other metals, up to 401W/MK.

2. Heavy copper PCB:

Heavy copper PCB refers to PCB with copper thickness exceeding 3OZ. The substrate can be aluminum or FR4. Heavy copper is to enable PCB to carry large current. Please note that Heavy copper here does not refer to the thickness of PCB, but the thickness of copper foil on PCB. Both aluminum PCB and FR4 PCB can thicken the copper foil.

What is the maximum copper thickness on Heavy copper PCB?

‌The maximum thickness of copper on Heavy copper PCB can reach 20oz. ‌

In circuit board design and manufacturing, copper thickness is an important parameter, which directly affects the electrical performance, heat dissipation capacity and mechanical strength of the circuit board. For applications that need to carry large currents, it is necessary to choose a thicker copper layer.

The copper layer thickness of Heavy copper ultra-thick PCB is generally between 2oz and 20oz. This range of copper layer thickness can ensure the stability and reliability of the circuit board while providing good heat dissipation performance.

In practical applications, according to international standards, the copper thickness of PCB boards can be divided into standard copper thickness and non-standard copper thickness. Standard copper thickness includes 1oz (35um) and 2oz (70um), while non-standard copper thickness covers 0.5oz (17um), 3oz (105um) and 4oz (140um). For some special applications, such as high-power LED lights, electronic high-frequency circuits, etc., a higher copper thickness may be required. At this time, non-standard copper thickness will be selected, up to 20oz.

During the manufacturing process, a Heavy copper foil is first adhered to the substrate, and then the circuit pattern is transferred to the copper foil through a photolithography process. Then chemical etching is performed to remove excess copper, and finally the thickness of the copper layer is further increased through an electroplating process to ensure that the Heavy copper PCB can meet the requirements of high current and high power applications.

Finally, surface treatment is performed to protect the copper circuit from oxidation and corrosion. Common surface treatment methods include hot air leveling (HASL), lead-free tin spraying, nickel gold (ENIG), etc. During the entire manufacturing process, process parameters must also be strictly monitored to ensure the uniformity and thickness consistency of the copper layer.

What are the advantages of Heavy copper PCBs?

1. Heavy copper PCBs have better current conductivity and can withstand excessive current loads. Because thicker copper wires have higher current carrying capacity, their current carrying capacity can be increased by increasing the copper wire width.

2. Heavy copper inner layers are ideal power distribution layers in multi-layer PCBs, which minimize ground bounce and power supply noise

3. Improve thermal performance and increase heat dissipation. Can withstand repeated thermal cycles during manufacturing and assembly.

4. Provide high mechanical strength in connector locations and plated through holes.

5. Due to the presence of copper layers, the size of the circuit board is reduced.

What are the disadvantages of Heavy copper PCBs?

1. Heavy copper PCBs are more expensive to manufacture than standard PCBs because more specialized equipment and richer expertise are required.

2. Heavy copper PCBs are more difficult to process because the PCBs may be heavier and bulkier than other PCBs.

What are the properties of Heavy copper PCBs?

High mechanical strength: After Heavy copper is applied to the circuits and vias of the board, the printed circuit board has super high mechanical strength, and the weather resistance of the circuit board and electrical system is more stable and has a high melting point. Hot melt welding methods such as oxygen blowing can be used, and it is not easy to become brittle at low temperatures. Even in an extremely corrosive atmospheric environment, Heavy copper PCBs can form a strong, non-toxic passivation protective layer.

Excellent weather resistance: Because Heavy copper PCB boards support the selection of a variety of dielectric materials. It improves the overall weather resistance of the board and can ensure the stability of circuit transmission signals under certain high temperature or extreme special environments.

Thermal management: With the advancement of modern technology, PCBs are becoming more and more complex, and high-density currents increase the difficulty of thermal management. Excessive temperature will affect the normal operation of electronic equipment and even cause damage. Heavy copper PCB boards can provide stronger heat dissipation capabilities. With heat sinks and copper plating on through holes, the heat generation of the board can be greatly reduced.

Excellent current conductivity: In the operation of electronic equipment, Heavy copper printed circuit boards are excellent current conductors that can connect and transmit power between various boards.

Diversity: Plating of Heavy copper circuits allows Heavy copper PCB manufacturers to increase the copper weight of via sidewalls and plated holes, thereby reducing the number of layers and occupied space.

Ductility: Heavy copper PCBs have the best ductility and are not limited by processing temperature.

High performance: Heavy copper plating integrates high current and control circuits, allowing high density with a simple board structure.

Where are Heavy copper PCBs used?

1. Automotive electronics

2. Grid switching systems

3. Power line monitors

4. Security and signal systems

5. Radar monitoring systems

6. Industrial control

7. Aerospace

8. Telecommunications

9. Medical devices

Conclusion:

In PCB production, Heavy copper PCBs require special processes, are difficult to operate, and have certain technical barriers, so the production cost of Heavy copper PCBs is higher than other ordinary circuit boards. Although the price is not cheap, the quality and service are the best.

The influence of copper thickness on PCB

Monday, August 19th, 2024

Copper thickness has a very important impact on the performance of PCB, and PCBs with different copper thicknesses also have very different applications. The fundamental reason why copper is widely used in circuit board manufacturing is its electrical conductivity, so different copper thicknesses correspond to different electrical conductivities. In addition, copper also has low resistance and thermal stability.

Why fill PCB with copper?

The main purpose of using copper to fill PCB (Printed Circuit Board) is to improve the electrical conductivity of the circuit board, enhance mechanical strength and stability, protect the circuit board from oxidation or corrosion, and improve heat dissipation capabilities. ‌

The influence of copper thickness on PCB

As an excellent conductive material, copper plays a vital role in PCB design. By covering the surface of the PCB with copper foil, the conductive performance of the circuit board can be significantly improved and the connection between various components can be ensured to be more stable and reliable.

Copper foil itself has high mechanical strength and stability, which can effectively prevent PCB from being damaged or deformed due to the influence of the external environment. The corrosion resistance of copper foil can also protect the circuit board from oxidation or corrosion, thereby extending the service life of the circuit board and ensuring its stability and reliability during work.

Since metal has good electrical and thermal conductivity, copper coating can increase the heat dissipation surface area of the PCB, help distribute heat evenly, and prevent the generation of local high-temperature areas. This can not only reduce local heat concentration, but also reduce the temperature gradient of the heat source and improve heat dissipation efficiency.

To sum up, the role of copper-filled PCB is multi-faceted. It can not only improve the conductivity and mechanical stability of the circuit board, but also protect the circuit board from environmental influences, while enhancing the heat dissipation capacity and ensuring the stable operation of electronic equipment. and long-term use‌.

Is a thicker PCB copper better?

The copper thickness of PCB is not as thick as possible, but the appropriate copper thickness needs to be selected according to the design requirements and actual application of the circuit board. ‌

The importance of copper thickness in PCB manufacturing cannot be ignored because it directly affects the conductive performance, heat dissipation performance, mechanical strength and signal integrity of the circuit board. Proper copper thickness can provide good electrical and thermal conductivity while ensuring the reliability and stability of the circuit board.

Although an excessively thick copper layer can improve current carrying capacity and heat dissipation performance, it will also increase cost and weight, which may lead to serious glue flow and increased processing difficulty. Therefore, when selecting copper thickness, factors such as circuit board design requirements, application environment, and cost need to be comprehensively considered.

During the PCB design and manufacturing process, the optimal copper thickness should be selected based on specific application requirements and cost considerations to achieve optimal circuit performance, heat dissipation, and mechanical strength‌.

How thick is the copper on a 1 ounce copper PCB?

The thickness of 1 ounce of copper on a PCB is 35 microns. ‌

In the PCB industry, ounces (oz) are the unit used to express copper foil thickness, not weight. Specifically, the thickness of 1oz of copper refers to the thickness achieved by spreading 1oz of copper evenly over an area of 1 square foot.

According to different information, the thickness of 1oz copper can be obtained by different calculation methods, but the generally accepted value is that 1oz copper is equal to 1.4mil (milliinch), which is equivalent to 35 microns. Therefore, whether in international standards or practical applications, the thickness of 1oz copper on PCB is usually considered to be 35 microns.

In addition, the copper thickness of the PCB has a direct impact on the circuit board’s current carrying capacity, heat dissipation, reliability and other performance indicators. Commonly used PCB copper thickness specifications include 1oz, 2oz, 3oz, 4oz, 5oz, 6oz, etc., which correspond to different copper layer thicknesses. The copper layer thickness of 1oz is 35 microns, 2oz is 70 microns, and so on, 6oz is 210 microns. . These specifications provide the basis for selecting different copper thicknesses based on specific application needs to meet different electrical performance and physical requirements.

What is the conventional PCB copper thickness?Thick copper plate, FPC

‌Regular PCB copper thickness is 1oz (35μm). When the thickness of the copper foil reaches or exceeds 2oz, such a PCB board is defined as a thick copper board; for flexible circuit boards (FPC), the copper thickness also has different specifications, for example, 0.5oz copper thickness is used for flexible circuit boards is being manufactured. ‌

In PCB manufacturing, the choice of copper thickness is determined based on specific application requirements. Common copper thickness classifications include:

1. ‌1oz copper thickness: ‌

This is the most common and standard copper foil thickness and is widely used in everyday electronic devices and general applications. 1oz (ounce) means 1 ounce of copper foil weighs 1 square foot. In the PCB manufacturing process, 1 ounce corresponds to a copper foil thickness of approximately 35 microns, which has good electrical and thermal conductivity.

2. ‌2oz copper thickness: ‌

Copper foil of this thickness is usually used in circuits that require higher current carrying capabilities, such as power amplifiers, high-power LEDs, etc. 2oz copper thickness corresponds to a copper foil thickness of approximately 70 microns, which has better performance in electrical conductivity and heat dissipation than 1oz copper thickness.

3. ‌0.5oz copper thickness: ‌

This thinner copper foil thickness is suitable for some light and small electronic products, such as electronic watches, mobile phones, etc. 0.5oz (18μm) copper foil is suitable for equipment that has strict requirements on circuit board size and weight.

How to choose PCB copper thickness?

Choosing PCB copper thickness depends primarily on the board’s purpose, current requirements, signal integrity requirements, cost budget, and manufacturing process capabilities.

1. ‌Circuit board usage and current requirements‌: For circuit boards that need to handle large currents, such as power boards, it is recommended to use thicker copper foil, such as 2oz (about 70μm) or 3oz (about 105μm). For signal transmission, a copper thickness of 1oz (~35μm) is usually sufficient. Ordinary double-sided boards generally use 1oz copper thickness, while multi-layer boards generally use 1/2oz, 1/3oz copper thickness for the inner layer, and 1oz, 1/2oz, 1/3oz copper thickness for the outer layer.

2. Signal integrity requirements: For high-density interconnect (HDI) boards or high-frequency circuits, thinner copper foil may be required to reduce parasitic effects and ensure signal integrity.

3. ‌Cost considerations‌: The thicker the copper foil, the higher the cost is usually.

4. Environmental factors: For PCBs in extreme working environments (such as high temperature, high humidity or high vibration environments), the thickness of the copper foil may need to be adjusted to enhance the stability and durability of the circuit.

In summary, selecting PCB copper thickness is a process that comprehensively considers multiple factors and needs to be determined based on specific application scenarios and design requirements.

What is the difference between different copper thicknesses on PCB?

‌The main differences between different copper thicknesses on PCBs are their conductive properties, load-bearing capacity, anti-interference performance, cost and manufacturing difficulty. ‌

‌Outer copper thickness‌ is commonly used for circuit board routing and connections, and its selection depends on the application requirements and design needs of the circuit board. The outer copper thickness range is generally between 1-5oz, and the more common ones are 1oz, 2oz, 3oz and 4oz. The thicker the outer copper layer, the stronger the circuit board’s load-bearing capacity, and the better its anti-interference performance and electrical conductivity. But at the same time, the increase in the thickness of the outer copper layer will also lead to an increase in cost and manufacturing difficulty.

‌Inner layer copper thickness‌ is used for internal connections and signal transmission of the circuit board, and its selection also depends on the application requirements and design needs of the circuit board. The thickness of the inner copper layer generally ranges from 0.5-2oz, with the more common ones being 0.5oz, 1oz, and 2oz. If the circuit board needs to transmit high-speed signals, a larger inner copper thickness should be selected. The increase in the thickness of the inner copper layer will also lead to an increase in cost and manufacturing difficulty.

‌Copper Thickness Standard‌According to international standards, the copper thickness of PCB boards can be divided into standard copper thickness (such as 1oz and 2oz) and non-standard copper thickness (such as 0.5oz, 3oz and 4oz). In practical applications, some special PCB boards may require higher copper thickness, such as high-power LED lights, electronic high-frequency circuits, etc.

To sum up, the choice of different copper thicknesses is to meet specific circuit board design needs, including conductive performance, anti-interference performance and other requirements. At the same time, the choice of copper thickness also needs to consider aspects such as cost and manufacturing difficulty.

Conclusion:

By controlling the thickness of copper on the PCB to meet different usage requirements, applications that require large currents will naturally require PCBs with thicker copper foils. However, PCBs that require thicker copper foils are a great test of the capabilities of PCB manufacturers. BEST Technology has accumulated rich production experience in the PCB manufacturing industry and has many years of manufacturing experience for PCBs with different copper thicknesses. We can meet any PCB copper thickness requirements.

Let you know about PCB copper layer thickness

Friday, August 16th, 2024

In the printed circuit board industry, the most common way to express the copper layer thickness on a PCB is in ounces (oz). 1oz means 1oz of copper evenly covers an area of 1 square foot, which is about 1.4mil. It uses the weight of the tissue area to express the average thickness of the copper foil. Expressed in terms of formula, 1oz=28.35g/FT2 (FT2 is square feet, 1 square foot = 0.09290304 square meters).

What is the standard thickness of a copper layer on a PCB?

In the manufacture of printed circuit boards (PCBs), the thickness of the copper layer is an important parameter that directly affects the electrical performance and reliability of the circuit board. Depending on the application requirements, the thickness of the copper layer can vary within a certain range. Generally speaking, the conventional copper layer thickness is between 1-35μm, with 35μm being the most commonly used thickness. For some applications with high reliability requirements, the copper layer thickness may reach more than 50μm.

The selection of the thickness of the copper layer is a decision-making process that takes into account a variety of factors, including the conductivity, heat dissipation, mechanical strength, cost and manufacturing difficulty of the circuit board. A larger copper thickness can reduce resistance and improve the conductivity and heat dissipation of the circuit board, but it will also increase material costs and production difficulties. Therefore, when designing PCB boards, engineers need to select a suitable copper thickness standard range based on specific application scenarios and design requirements to ensure the performance and reliability of the circuit board.

1oz copper thickness in mm = 0.035mm

0.5 oz copper thickness in mm = 0.0175mm

1.5 oz copper thickness in mils = 0.0525mm

2 oz copper thickness in mils = 0.07mm‌

How thick is PCB copper after plating?

PCB printed circuit boards are usually bonded to glass epoxy substrates with a layer of copper foil, usually 18, 35, 55 and 70 microns thick. The most commonly used copper foil is 35 microns thick.

The copper foil used by PCB manufacturers is generally 35~50 microns thick, and some are thinner than this, such as 10 microns, 18 microns, and thicker such as 70 microns. The thickness of the composite copper foil on a 1~3 mm thick substrate is about 35 microns. The thickness of the composite copper foil on a substrate with a thickness of less than 1MM is about 18 microns, and the thickness of the composite copper foil on a substrate with a thickness of more than 5 mm is about 55 microns.

The copper layer thickness of PCB (printed circuit board) can be adjusted according to different needs and designs. Common copper layer thicknesses include 1oz (35μm), 2oz (70μm), 3oz (105μm), and other thicker options. For most applications, a copper layer thickness of 1oz is sufficient and suitable for general signal transmission. ‌For circuit boards that need to carry large currents, such as switching power supplies, a copper layer thickness of 2oz or higher is usually used. ‌In addition, there are some special cases where manufacturers provide extremely heavy copper up to 20 oz/ft2 (26.8 mils or 0.34 mm) to meet special needs. ‌

When choosing the thickness of the copper layer, factors such as the purpose of the circuit board and the magnitude of the signal voltage and current need to be considered. ‌For example, for circuit boards that require excessive current, a copper thickness of 70μm or 105μm may be used. ‌For thin laminates that require ultra-high density patterns, a copper thickness of 12μm may be used. ‌Therefore, the specific thickness of the PCB after copper plating is determined according to design requirements and specific applications.‌

How thick is 2 oz copper for PCB?

If 1 ounce (28.35 grams) of copper were flattened to evenly cover a surface area of 1 square foot (0.093 square meters), the resulting thickness would be 1.37mils (0.0348mm). A conversion chart for different units of measurement can be found below.

What is the difference between different copper thicknesses in PCB?

‌Copper is an excellent conductive material, and the thickness of the copper layer directly affects the conductive effect of the circuit board. ‌Thicker copper layers can provide lower resistance, reduce signal transmission losses, and are particularly suitable for high-frequency and high-speed digital circuits. ‌

During the operation of electronic equipment, good heat dissipation is a key factor in ensuring the performance and life of components. ‌Thicker copper layers can conduct and dissipate heat more effectively, preventing components from overheating. ‌

In high-power electronic devices, thicker copper layers can carry larger currents, avoiding burnout or performance degradation caused by excessive current.

Below is the conductivity corresponding to different copper thicknesses.

How thick is high current PCB copper?

In PCB design, copper thickness (also called copper thickness) is an important parameter, which directly affects the performance indicators of the circuit board such as current carrying capacity, heat dissipation and reliability. For PCBs that need to withstand high currents, such as high-power LED light strips, power circuit boards, high-power motor control boards or high-power inverter control boards, thicker copper layers are usually used to increase current carrying capacity.

Different uses have different copper foil thicknesses. Common 0.5oz, 1oz, and 2oz are mostly used in consumer and communication products. Thick copper products above 3oz are mostly used for high currents, such as high-voltage products and power boards.

The thickness of copper foil (track width) will affect the current size. Although there is a formula that can directly calculate the maximum current carrying capacity of copper foil, it is not so simple when actually designing the circuit. Therefore, the safety factor should be fully considered during the design.

How thick is the copper in a flex PCB?

The thickness of copper foil in flexible PCB is generally 18μm, 35μm, 55μm and 70μm. These thickness specifications are suitable for different types of circuit board requirements, among which 35μm is the most commonly used copper foil thickness.

For flexible PCB, the choice of copper foil thickness depends on the specific purpose of the circuit board and the size of the signal voltage and current. For example, for PCBs that require excessive current, some parts will use 70μm copper thickness, while for signal transmission, 1oz (35μm) thickness is usually sufficient. In addition, for substrates of different thicknesses, the thickness of copper foil is also different. For example, the thickness of the composite copper foil on a 1mm thick substrate is about 18μm, and on a substrate thicker than 5mm, the thickness of the composite copper foil is about 55μm.

Conclusion:

PCBs for different usage scenarios correspond to different thicknesses of copper, and its thickness directly affects the conductive effect of the circuit board. If the copper layer is too thin, the conductivity may decrease, resulting in signal transmission attenuation or current instability. If the copper layer is too thick, although the conductivity will be very good, it will increase the cost and weight of the circuit board and easily lead to serious glue flow. In PCB manufacturing, it is necessary to select the appropriate copper thickness according to the design requirements and actual applications of the circuit board to achieve the best conductive effect.

BEST Technology is a professional PCB circuit board manufacturer with a large area of site and equipped with useful and experienced production personnel. Corresponding to different thicknesses of copper, we have rich production and processing experience. We can meet the requirements of any circuit board copper layer thickness.‌

Drone Circuit Board: What It Is and How to Make a Drone PCB Board?

Friday, August 16th, 2024

What is a Drone Circuit Board?

A drone circuit board refers to the electronic component board installed in a drone that controls and manages its various functions. It serves as the core control system of the drone, similar to how a brain functions in the human body. The drone circuit board controls all operations, including flight, photography, and video recording. It is the central system that coordinates all activities.

Depending on different functions and application scenarios, drone circuit boards can be classified into various types, such as flight control boards, video transmission boards, and power control boards. Among these, the flight control board can be considered a type of drone circuit board but is not equivalent to it. The flight control board mainly controls parameters such as flight direction, altitude, and speed, and adjusts the drone’s posture to ensure stable flight. The drone circuit board, however, not only controls flight but can also implement auxiliary functions such as GPS positioning and image transmission.

What Board is Used in Drones?

In drone design, the two most common types of circuit boards are rigid-flex boards and traditional PCB boards. Rigid-Flex PCB is a hybrid type of PCB that combines rigid and flexible circuit boards. It allows the board to bend and fold in tight spaces, which is particularly useful for compact drones that require a highly integrated design. Moreover, rigid-flex boards are lightweight and thin, which is advantageous for drone designers looking to enhance flight time and stability.

Traditional PCB Boards are another common type of circuit board used in drone design. These boards have strong mechanical strength, making them suitable for the core control units in drones, such as flight control boards and ESC boards (Electronic Speed Controllers).

Below are the main types of circuit boards commonly found in drones:

Control Circuit Board

The control circuit board is one of the most important boards in a drone. It typically consists of the main control chip, sensors, and electronic speed controllers (ESC). The main control chip acts as the brain of the drone, receiving wireless signals and controlling the flight posture and movement based on user commands. Sensors can detect the drone’s position and motion in real-time, ensuring stable flight control. The ESC adjusts the motor speed and direction, which directly impacts the drone’s flight.

Power Supply Circuit Board

The power supply circuit board is responsible for providing power to the drone, ensuring proper voltage and current. It must prevent issues like overcurrent, overvoltage, and overheating to maintain the drone’s performance.

Navigation Circuit Board

The navigation circuit board determines the drone’s position and direction, with the GPS module as the core component. GPS helps obtain satellite signals, calculating important information such as latitude, longitude, and altitude, to ensure precise navigation and positioning. The board may also include other sensors like barometers, gyroscopes, and accelerometers to enhance navigation accuracy.

Communication Circuit Board

The communication circuit board typically includes WiFi, Bluetooth, and 4G/5G modules, which allow the drone to connect with ground control stations or user devices for data transmission, remote control operations, and video streaming.

Why Use a Drone Circuit Board?

Besides the central chip, drone circuit boards serve many critical functions, such as power management and signal transmission. Let’s take a closer look at their functionality:

Power Management

The power management chip on a drone circuit board controls and regulates the power supply. Unlike regular circuit boards, the power management module in drones must be efficient, low-power, and lightweight. Since drones often need to fly for hours, improper design of the power management module can severely impact flight time and energy utilization.

Collecting data

The sensor chip on the drone circuit board is responsible for collecting data, such as GPS location, barometric pressure, and posture. The sensor chip processes data from wireless sensors and transmits it to the control chip for decision-making.

Control the drone

The control chip is the most vital part of the drone circuit board, managing and coordinating all aspects of the drone’s operation, including GPS navigation, servos, and motors. The microprocessor in the control chip uses algorithms to control flight while processing real-time sensor data.

Data Transmission

When capturing aerial photos or videos, the drone needs to send the recorded data to ground devices. The data transmission chip on the drone circuit board ensures that this information is transmitted to ground equipment. Many drones also support wireless network connections for seamless communication.

How to Make a Drone PCB?

To make a drone PCB, you’ll need to prepare the following materials:

STM32F405RGT6 microcontroller, which is stable and suitable for various drone applications.
2.4G CC2500 wireless module based on the UART protocol for data communication with the remote control.
Sensors like accelerometers, gyroscopes, magnetometers, barometers, GPS, etc., to provide sensor fusion for precise drone control.
Power Module
Other components including resistors, capacitors, diodes, voltage regulators, and other basic circuit components.

Here is the way to create the drone PCB step by step:

1. Design

You can use PCB software to design the schematic and PCB layout, determining key parameters like circuit connections and component placement.

2. Printing and Etching

Print the designed circuit board pattern onto transparent stickers and attach them to copper sheets. After etching and removing the stickers, the circuit board will be ready.

3. Soldering

Solder the components onto the circuit board. It’s essential to leave adequate pads for soldering during the design phase.

4. Testing

Test the soldered circuit board to ensure normal functioning of the circuits.

What Should We Consider When Designing a Drone PCB?

Make sure enough power, ground, and data lines are allocated to each component to avoid signal interference and noise.

Take measures to protect components from static electricity during soldering.

Write clear and standardized comments in your program for easier modifications and debugging later.

Double-check that the board’s connections are in the correct order to prevent damage to the control board.

Is a Fuse Board the Same As a Distribution Board?

No, a fuse board and a distribution board serve different purposes in a drone’s electrical system.

Fuse board is designed to protect your components from power surges or short circuits. It contains fuses that blow if too much current flows through them, cutting off power to prevent damage.

Distribution board is simply distributes power from the battery to different components of the drone, such as the ESCs and flight controller. It doesn’t have the protective features of a fuse board.

In some designs, both can be combined into one board, but their functions remain distinct.

How can I Increase my Drone Power?

Increasing your drone’s power can improve performance, allowing it to carry more weight or fly faster. You can use below ways to increase the power:

Upgrade motors

Increase battery capacity

Use better propellers

Optimize power distribution

Improve efficiency: Compared with resin via filling or other materials via filling, via filling plating has a simpler process and higher efficiency.
Process flow and technical challenges of via filling plating
Process flow: including steps such as tank preparation, setting of electroplating process control parameters, and analysis of potion addition.
Technical challenges: including positioning accuracy issues and electroplating quality issues, which need to be solved by strictly controlling parameters such as electroplating time and current density.

Application scenarios of hole filling electroplating

First-order HDI: Suitable for electronic devices with less complex circuits.
Second-order and above blind hole electroplating copper filling: Suitable for more complex electronic devices, such as mobile phones, laptops, etc.
Comparison between hole filling electroplating and full-board electroplating
Full-board electroplating: Although it can provide a uniform surface copper thickness distribution, it may encounter the problem of residual dry film on the board surface or in the hole during pre-treatment, resulting in some areas unable to be plated with copper. In addition, the etching process after full-board electroplating may cause quality defects such as side etching and fine lines.
Hole filling electroplating: Compared with full-board electroplating, hole filling electroplating is more accurate in filling blind holes, avoiding the problems that may be encountered in full-board electroplating, while simplifying the process and improving efficiency.

Materials of HDI PCB

The materials of HDI PCB mainly include coated copper foil (RCC), prepreg, copper foil, etc.

Resin-coated copper foil (RCC): This is a material that coats a special resin film layer on electroplated copper foil, used for HDI insulation layer. The characteristics of RCC include no glass dielectric layer, easy laser and plasma micro-hole forming, extremely high peel strength and good toughness, suitable for micro-narrow line etching. Laser drilling is performed on RCC, and the aperture shape formed is an inverted trapezoid, and the general aperture size is 0.076-0.10 mm. The use of RCC makes HDI PCB more widely used in small portable products, such as mobile phones, digital cameras, laptops, etc.

Prepreg and copper foil: These are basic materials in HDI PCB manufacturing, there are no special requirements, and they are suitable for different types of HDI PCB structures. The inner layer circuits are generally 1 ounce copper thick, while the outer layer circuits are plated with half an ounce of base copper to 1 ounce of finished copper thickness. The thickness of the board is usually thinner to meet the miniaturization requirements of HDI PCB.

Other materials: In addition to the main materials mentioned above, the manufacture of HDI PCBs may also involve other materials, such as FR4, PI (polyimide), BT, etc. These materials are selected according to specific application requirements. For example, FR4 has good electrical and mechanical properties and is suitable for most general applications; PI has higher heat resistance and chemical corrosion resistance, and is suitable for high temperature, high humidity and strong acid and alkali environments, but it is more expensive and difficult to process; BT combines good electrical properties, mechanical properties and thermal stability, and is suitable for application scenarios that require higher heat resistance.

HASL Lead Free vs ENIG: Understanding Their Differences

Tuesday, August 13th, 2024

When it comes to PCB surface finishes, choosing the right one is essential for the longevity and performance of your circuit board. Among the many options available, two of the most popular are Hot Air Solder Leveling (HASL) and Electroless Nickel Immersion Gold (ENIG). These two methods offer distinct advantages depending on the application, and understanding their differences can help you select the best finish for your project.

HASL Lead Free vs ENIG: Understanding Their Differences

What Does HASL Stand For?

HASL stands for Hot Air Solder Leveling. It is a surface finish process used in PCB manufacturing. The term describes the method where solder is applied to the copper pads on a PCB and then leveled using hot air to ensure even coating. HASL is widely used because of its simplicity and effectiveness in providing a reliable solderable surface.

What Is HASL in PCB?

In PCB manufacturing, HASL is a surface finish applied to the exposed copper pads to protect them from oxidation and to provide a good surface for soldering components. The HASL process involves dipping the PCB into molten solder, typically composed of a lead-free alloy, and then using hot air to remove excess solder, ensuring a smooth and even layer. This finish is particularly valued for its excellent solderability and cost-effectiveness.

Characteristics of Hot Air Solder Leveling

Hot Air Solder Leveling is a widely used surface finish in PCB manufacturing due to its unique set of characteristics that make it suitable for various applications. Below are the key attributes that define HASL:

1. HASL provides one of the most solderable surfaces available for PCB assembly. The molten solder applied during the HASL process creates a coating that is highly receptive to soldering, making it easy to attach components.

2. Compared to other surface finishes like ENIG or OSP, HASL is generally more affordable.

3. The solder coating provided by HASL serves as a protective layer for the copper pads on the PCB. This layer helps prevent oxidation and corrosion.

4. Variability in coating thickness. The hot air leveling process can result in uneven distribution of solder, leading to variations in thickness across the PCB. While this might be a drawback for designs requiring fine-pitch components or precise tolerances, it is often acceptable in less demanding applications where slight variations are not critical.

5. Thermal resistance. The solder layer provided by HASL can withstand multiple thermal cycles during the PCB assembly process, such as during solder reflow.

6. The HASL process creates a strong bond between the solder and the underlying copper pads.

What Is the HASL Method?

The HASL coating process is a critical step in PCB manufacturing, designed to protect the exposed copper pads and good solderability during the assembly of electronic components. The process is under several steps, each carefully controlled to achieve a uniform and reliable coating. Here’s a detailed look at how HASL is applied to a PCB:

1. Pre-Cleaning the PCB

The HASL process begins with thoroughly cleaning the PCB to remove any contaminants such as oxidation, oils, or residues from previous manufacturing steps. This is typically done using a combination of chemical cleaning agents and mechanical scrubbing.

2. Flux Application

After cleaning, a layer of flux is applied to the PCB. Flux is a chemical agent that serves multiple purposes: it removes any remaining oxidation from the copper pads, improves the wetting of the solder, and helps the solder adhere more effectively to the copper. The type of flux used can vary, but it must be compatible with the solder alloy to ensure a reliable coating.

3. Solder Bath Dipping

The PCB is then dipped into a bath of molten solder. For lead-free HASL, the solder typically consists of a tin-silver-copper (SAC) alloy, which is heated to a temperature between 240°C and 260°C (464°F to 500°F). The molten solder covers the entire surface of the PCB, including the copper pads and through-holes, forming a protective layer.

4. Hot Air Leveling

Once the PCB is removed from the solder bath, it immediately undergoes the leveling process. The board is passed through a pair of hot air knives positioned on either side. These knives blow high-pressure, heated air across the surface of the PCB, removing any excess solder and ensuring a uniform layer remains on the pads.

5. Cooling

After leveling, the PCB is cooled to solidify the solder coating. This cooling is typically done using an air or water-based cooling system, depending on the specific requirements of the manufacturing process. Rapid cooling can sometimes introduce stresses into the solder layer, so the cooling rate must be carefully controlled to avoid defects like cracking or warping.

6. Post-Process Cleaning

In some cases, the PCB may undergo a final cleaning step to remove any flux residues or other contaminants that might remain after the HASL process. And then testing and inspection.

What Is the Difference Between HASL and ENIG Finish?

While both HASL and ENIG are popular PCB surface finishes, they differ significantly in their composition, application, and performance:

Characteristic	HASL	ENIG
Cost	Lower cost, suitable for budget-sensitive projects	Higher cost, but justifiable for high-reliability needs
Solderability	Excellent, but may vary with coating thickness	Consistent, even for fine-pitch components
Durability	Reasonable, but less effective in harsh environments	Superior, with excellent corrosion resistance
Thermal Performance	Good, but uneven surface might cause issues	Excellent, with consistent performance in high-heat scenarios
Best Suited For	General-purpose electronics, consumer products	High-reliability applications, aerospace, medical, and high-density PCBs
Surface Flatness	May have uneven surface, less ideal for fine-pitch components	Extremely flat surface, ideal for precise component placement
Environmental Impact	Lead-free HASL is environmentally safer, but traditional HASL uses lead which is harmful	Environmentally friendly, as it doesn’t use lead or other harmful materials
Shelf Life	Shorter shelf life due to potential oxidation over time	Longer shelf life due to gold’s resistance to oxidation
Reworkability	Easier to rework due to the nature of solder	More challenging to rework due to hard nickel layer

HAL vs. HASL

HAL (Hot Air Leveling) and HASL (Hot Air Solder Leveling) are terms often used interchangeably, but they can refer to slightly different processes. HAL is a broader term that encompasses any method of leveling solder using hot air. In contrast, HASL specifically refers to using solder to coat the PCB’s surface. Essentially, all HASL processes are HAL, but not all HAL processes are HASL.

What Is the Composition of HASL?

At present, the solder of lead-free solder alloy hot air leveling is mainly Sn-Cu-Ni+Ge (germanium) or Sn-Cu-Ni+Co (cobalt). The components of Sn-Cu-Ni+Ge (Germanium) in the OPA2544T are Sn, 0.7% Cu, 0.05% Ni and Ge with a nominal content of 65×10-6. Germanium can not only prevent the growth of oxides, but also prevent the solder joints on the PCB pad coating surface from yellowing and tarnishing during the HASL process and subsequent reflow welding and wave soldering processes. In addition, germanium can also inhibit the formation of slag in lead-free wave soldering.

The biggest problem in the lead-free HASL process is the problem of sinking copper in the tin tank during the use of the equipment.

The typical operating temperature range of the HASL process is 265 to 275 ° C, and this temperature range can be used for almost all actual manufactured laminates. At this temperature, even CEM1, there is no problem of delamination and degradation. However, the actual process temperature increases with the increase of copper composition in the tin tank. When the copper composition is 0.3% higher than the optimal value of 1.2%, then the welding temperature must be increased to 285 ° C, which is not the laminate can withstand. Although a copper-free solder alloy can be added to reduce the copper content in the tin tank, it is difficult to control the proportion.

The so-called “freeze-drying” method can also be used. When the tin lead eutectic solder (63Sn-37Pb) temperature drops to about 190℃, the melting tin copper intermetallic compound (Cri6Sn5) will be “freeze-dried”. In high-density lead solders, Cu6Sn5 floats on the surface of the molten solder and can be skimmed out using a slotted spoon. However, in lead-free solder, Ct16SIl5 is denser than lead-free solder, and CLJ6Sn5 will settle to the bottom of the tin tank. There is a mechanism to reduce the temperature to about 235 ° C (about 8 ° C higher than the melting point temperature), the tin tank shut down for at least two hours, preferably all night, at this time, most of the alloy is still in a molten state, you can design special tools, from the bottom of the tin tank out of the precipitation of Cr16Sn5, but it is still very difficult.

What Is the Minimum Pitch for HASL?

The minimum pitch for HASL refers to the smallest distance between two adjacent pads that can be reliably soldered using the HASL process. Due to the nature of the hot air leveling process, which can create uneven surfaces, HASL is generally not recommended for very fine-pitch components. The minimum pitch is typically around 0.65mm, but it can vary depending on the specific requirements and the quality of the HASL process used.

Does HASL Oxidize?

One of the main concerns with any PCB finish is oxidation, which can affect solderability and reliability. While HASL provides a protective solder layer that helps prevent oxidation, it is not entirely immune. Over time, especially in harsh environments, the solder can oxidize, leading to potential issues during assembly. However, proper storage and handling can minimize this risk, making HASL a reliable choice for many applications.

How Thick Is the HASL Coating?

The thickness of the HASL coating can vary depending on the process parameters and the type of solder used. Typically, the thickness ranges from 1 to 25 microns. This variability can be a drawback for applications requiring precise and consistent thickness, especially for fine-pitch components. However, for many general-purpose applications, the thickness provided by HASL is more than sufficient.

What Is the Black Pad Syndrome?

Black pad syndrome is a phenomenon associated with the ENIG finish, not HASL. It occurs when there is an issue with the nickel layer during the ENIG process, leading to poor solder joints and potential failures. The term “black pad” refers to the appearance of the affected nickel layer, which turns black due to oxidation and contamination. While this issue is unrelated to HASL, it’s important to note that HASL does not suffer from black pad syndrome, making it a more straightforward and reliable finish in this regard.

What is Ceramic PCB? Its Types and Manufacturing Process

Tuesday, August 13th, 2024

Ceramic PCB is an innovation of traditional PCB circuit board. Ceramic PCB will use an organic compound called polyimide as solder paste, and ceramics (aluminum nitride, aluminum oxide, beryllium oxide) are often used as substrate materials. In the electronic power industry, ceramic PCB is a substitute for the traditional PCB technology based on FR-4 glass epoxy resin laminated with a thin copper layer.

The market of ceramic PCB is growing faster and faster because of its unique performance and cost-effectiveness. Compared with traditional FR4-PCB, they have many advantages, including thermal conductivity, chemical resistance, electrical insulation and high thermal shock resistance. So it is widely used in military, aerospace, consumer electronics industry and Internet of Things equipment.

What is Ceramic PCB? Its Types and Manufacturing Process

What is a Ceramic PCB?

Ceramic PCB or ceramic circuit board is a kind of printed circuit board using ceramic material as substrate. Different from the traditional PCB which often uses FR4 and other materials, ceramic PCB has better heat dissipation and electrical insulation. These characteristics make ceramic PCB an ideal choice for high-power applications such as LED lighting, power electronics and automotive electronics.

Commonly used ceramic materials for ceramic PCB generally include alumina (Al2O3), aluminum nitride (AlN) and silicon carbide (SiC). These materials can provide the necessary thermal conductivity and mechanical strength for ceramic PCB applications, and ensure that the circuit board can withstand high temperature and harsh working conditions.

One of the main advantages of ceramic circuit boards is that they can handle higher power load without overheating risk, which significantly improves the service life of ceramic PCB. At the same time, the low coefficient of thermal expansion (CTE) in ceramic materials also reduces the risk of thermal stress and further improves the durability of ceramic PCB.

How to Make Ceramic PCB?

Due to the unique properties of ceramic materials, the process of manufacturing ceramic PCB is more complicated than traditional PCB. The manufacturing process usually involves several key steps:

Firstly, the first step is to select the appropriate ceramic materials according to the specific requirements of the circuit board.

The second step is to press and sinter the ceramic powder into the required shape and thickness after selecting the material. The sintering process involves heating the material to a high temperature to fuse the particles together, thus forming a dense and solid substrate.

The third step is to deposit a layer of metal (usually copper or gold) on the surface after the substrate is formed, then apply photoresist material to the metal layer, and use ultraviolet rays to expose the required circuit pattern, and then etch away the exposed area, leaving the circuit pattern.

Finally, after the circuit is formed, the circuit board should go through a finishing process to improve its performance and durability. Finally, the quality of the finished circuit board should be checked to ensure that it meets all the required specifications.

This process can make ceramic PCB highly reliable and can work normally under extreme conditions.

How Many Layers in Ceramic PCB?

Ceramic PCB can be made of multiple layers like traditional PCB, and its number of layers depends on the complexity of the circuit and the application requirements.

Single-layer ceramic PCB is composed of a single-layer ceramic material and a metal circuit at the top, which is usually used for heat dissipation applications.

Multilayer ceramic PCB is more complex, consisting of multilayer ceramic materials and metal circuits, which are stacked together and interconnected by vias. The extra layer allows more complex circuit design, enabling the circuit board to handle more signals and power for applications requiring higher functions.

The number of layers in ceramic PCB can range from one to several. Each additional layer will increase the complexity and cost of the circuit board, but it will also increase its function and performance, depending on its application scenario.

How Thick is Gold Conductor Printed on the Ceramic PCB?

The thickness of gold conductor on ceramic PCB is an important factor affecting the performance and durability of circuit board. The thickness of gold conductor depends on the application and required performance characteristics, and is usually in the range of 0.5 micron to 10 micron. Of course, a thicker gold layer can also be provided, which also brings better conductivity and more stable performance, especially in high-power applications, which also brings higher costs.

In high frequency applications, the thicker gold layer can reduce the signal loss, improve the overall performance of the circuit, and also better prevent wear and prolong the service life of PCB.

Considering the specific requirements of the application, the exact thickness of the gold conductor has been determined in the design stage. Our advanced manufacturing technology enables us to accurately control the thickness of the gold conductor and ensure that each circuit board meets the required specifications.

What is the Ceramic insulator on the Circuit Board Used For?

Ceramic insulators are generally used to electrically insulate different components and conductive paths on a circuit board, prevent short circuits and ensure that the circuit operates as expected. It plays a vital role in the performance and reliability of ceramic circuit boards.

Even a small amount of current leakage will cause serious problems. Ceramic materials of insulators provide excellent electrical insulation performance, which means that they can withstand high voltage without allowing current to pass through. In addition to electrical insulation, ceramic insulators also have thermal insulation properties, which can help control the heat generated by components on the circuit board.

Ceramic insulators are usually placed between metal conductors on the circuit board, which allows multiple conductive paths to be placed closely together without the risk of short circuit because they are electrically insulated from each other.

Generally speaking, ceramic insulator is a key component of ceramic PCB, which helps to improve its performance and reliability.

What equipment does BEST Technology have?

We use advanced machines at every step of the production process, from substrate molding to circuit molding and surface treatment, to ensure the highest quality ceramic PCB.

For substrate forming, we have high-precision press and sintering furnace, which can produce dense and uniform ceramic substrates.

Our metallization process is also supported by advanced sputtering and chemical vapor deposition equipment to ensure that a consistent high-quality metal layer can be formed on the substrate.

At the same time, we also have cutting-edge lithography equipment for circuit formation, which enables us to create complex and accurate circuit patterns on the circuit board.

how to design flex rigid pcb?

Rigid-Flex Circuit Design Guidelines

To form a rigid-flex, follow these considerations to ensure the best results.

Considerations When Designing Rigid-Flex Circuits

To produce a rigid-flex PCB with unmatched quality and functionality, you must follow the correct manufacturing specifications. This is the set guidelines and standards that manufacturers must consider when designing and manufacturing flexible circuit boards.

Determine Manufacturing Process and Materials Beforehand

Depending on the flexibility you require, you need to decide beforehand what materials to use and the methods to use. Example; When the board you are designing only needs to be folded during manufacturing and thereafter be in a fixed position without bending, you can decide the following

Copper type and grade
Manufacturing method
Number of layers to be used.

On the other hand, if the board is for an application with frequent movement, vibration, and impact, you must be clear in choosing the following:

Copper Coils
Adhesives and
Number of Layers

Place Copper Traces at Right Angles to Rigid-Flex

Copperworks is a great fit when placed on the right edge of the board. Avoid bending copper traces at corners as it will pull stress and may not create the best bend. For PCB flex that requires bending, use sharp radius bends to avoid smudging copper traces.

Provide adequate pad support for exposed copper

Repetitive stress from frequent bending can cause copper on the circuit to break away from the polyimide substrate. Support exposed copper with pads to prevent separation.

Use hatched polygons

Hatched polygons instead of solidified copper help maintain the flexibility of flexible PCBs.

Leave at least 1/2mm gap between copper ring and adjacent vias

1/2mm helps avoid fatigue caused by frequent bending. Placing vias in fixed areas of the board helps avoid frequent movement and bending, resulting in the best rigid-flex.

An audio board, often referred to as a soundboard or mixer, is a crucial device in the world of sound engineering. Whether you’re working on a live concert, recording in a studio, or simply enhancing audio for a video production, understanding the role of an audio board is essential. This guide will walk you through what an audio board does, its various names, and how to set one up effectively.

What Does an Audio Board Do?

An audio board, or soundboard, manages and controls audio signals. It’s used in many settings, from live concerts to recording studios. The primary function of an audio board is to mix different audio sources, such as microphones and instruments, to create a balanced sound output. This device allows sound engineers to adjust levels, equalize sound frequencies, and add effects to enhance the overall audio experience.

In more technical terms, an audio board receives input signals, processes them, and sends them to an output device. This processing can include adjusting volume levels, panning audio between speakers, and applying effects like reverb or delay. The result is a well-mixed audio output that sounds harmonious and professional.

What is Also Called an Audio Board?

An audio board goes by several names, depending on its use and context. Commonly, it’s known as a soundboard or mixing console. In professional settings, you might hear it referred to as an audio mixer or sound mixer. These terms are often used interchangeably, but they all refer to the same essential device that manages and manipulates audio signals.

Whether you’re shopping for an audio board online or looking to upgrade your studio equipment, understanding these terms will help you find the right product for your needs.

What is the Working Principle of Audio Board?

The working principle of audio circuit refers to the process of audio signal transmission and processing in the circuit. In general, the frequency range of audio signals is 20Hz to 20kHz, and they are electrical signals used to transmit sound. The processing of audio signal includes amplification, mixing, filtering and so on.

Amplification refers to increasing the amplitude of the audio signal so that it can drive the speaker to produce a sound. The amplification process is generally achieved using an amplifier, the principle is to use the amplifier tube of the amplifier to amplify the input signal and then output it to the speaker.

Mixing refers to the process of mixing multiple audio signals into one signal. In a mixing circuit, multiple audio signals are mixed together through a mixer to output a composite signal. The mixer is generally composed of an operational amplifier and a mixer. The operational amplifier is responsible for adding multiple input signals, while the mixer is responsible for adjusting the volume ratio of each input signal.

Filtering refers to filtering the audio signal through a filter to remove unwanted frequency components. Filters are generally divided into low-pass filters, high-pass filters and band-pass filters. A low-pass filter only allows low-frequency signals to pass through, a high-pass filter only allows high-frequency signals to pass through, and a bandpass filter only allows signals in a certain frequency range to pass through.

Is a Sound Board the Same as a Mixer?

Yes, a soundboard and a mixer are essentially the same device. Both terms describe equipment used to blend and adjust audio signals. The term “mixer” is often used in professional audio production environments, while “soundboard” is more common in live sound settings.

The confusion between these terms arises from their varied applications. A soundboard is typically associated with live events, where audio engineers manage the sound in real-time. A mixer, on the other hand, might be used more broadly, encompassing both live and studio environments. Regardless of the term, the device’s primary function remains the same: to mix audio signals and produce a balanced sound output.
