What is PCB and PCBA?

Understanding the difference between PCB and PCBA is the first step when entering the electronics world.

  • PCB stands for Printed Circuit Board. It’s the bare board that holds all the components. It can be single-sided, double-sided, or multilayered depending on the design.
  • PCBA means Printed Circuit Board Assembly. This refers to the finished board with all components mounted. It’s the working version of the circuit that can be used in a product.

So, the key difference: PCB is the blank base, while PCBA is the complete board with parts soldered on.

How is a PCB Manufactured?

PCB manufacturing is a detailed process. Let’s simplify it into key steps:

Step 1: Design

  • Everything starts with a PCB design using CAD software. Gerber files are generated to guide the production.

Step 2: Printing the Inner Layers

  • The copper pattern is printed onto a laminate sheet. This forms the board’s inner circuits.

Step 3: Etching

  • Excess copper is removed using a chemical process, leaving only the desired traces.

Step 4: Layer Alignment

  • For multilayer boards, layers are stacked and aligned with precision.

Step 5: Drilling

  • Holes are drilled to create pathways between layers.

Step 6: Plating and Copper Deposition

  • The drilled holes are plated with copper to form conductive connections.

Step 7: Solder Mask Application

  • A green solder mask covers the board, except for areas where components will be soldered.

Step 8: Surface Finish

  • This step protects the exposed copper and improves solderability.

Step 9: Silkscreen Printing

  • Markings are printed to identify parts and polarity.

Step 10: Electrical Testing

  • Each PCB is tested to ensure the circuit paths are correct.

The board is now ready for assembly.

How Much Does PCB Assembly Cost?

PCB assembly cost depends on several variables. Here’s what affects the price:

  • Component types: SMT parts are usually cheaper to place than through-hole ones.
  • Quantity: Higher volumes lower per-unit cost.
  • Board size and layers: More layers or larger sizes mean higher assembly fees.
  • Turnaround time: Rush orders add to the price.
  • Testing requirements: If functional or in-circuit testing is needed, it adds cost.
  • Location of manufacturer: Prices vary by country or region.

On average, a basic PCBA could start at $10–$30 per board for small quantities. Higher-end boards cost more.

How Much Does a Custom PCB Cost?

Custom PCBs are priced based on the following:

  • Number of layers – A 2-layer board is cheaper than a 6-layer one.
  • Board dimensions – Larger boards use more material.
  • Surface finish – ENIG or immersion gold costs more than HASL.
  • Material – FR4 is standard. Ceramic, aluminum, or polyimide costs more.
  • Volume – A prototype might cost $100+, but bulk orders can drop it below $2 per piece.
  • Fabrication complexity – HDI boards or those with fine traces cost more.

What is PCB Heat Sink Pad? How to Design a Thermal Relief Pad?
Monday, April 21st, 2025

What is PCB Heat Sink Pad?

In high-power electronics, heat is a persistent issue. When left unmanaged, it leads to failure, reduced life span, or poor performance. One of the smart ways to address this is by using a PCB heat sink pad. Sometimes referred to as thermal relief pads, these are conductive areas on a printed circuit board that channel heat away from components. They play a critical role in thermal management, especially in compact and high-density board layouts.

These pads are often seen near power components, processors, or any part prone to heat buildup. By connecting to thermal vias or copper pours, they guide excess heat to ground or large copper areas. Thermal pads improve overall stability without the need for bulky external coolers. A well-designed thermal pad saves cost, space, and ensures better thermal cycling performance.

What is PCB Heat Sink Pad?

Importance of PCB Heat Sink Pad

The importance of a PCB heat sink pad lies in its ability to support both thermal and electrical performance. As devices get smaller and more complex, the demand for thermal balance grows. Traditional cooling methods, like fans or heatsinks, aren’t always viable in a tight layout. That’s where these pads step in.

They serve as an internal heat escape path. By reducing the junction temperature of critical parts, the heat sink pad ensures devices function at optimal levels. Without it, hot spots develop, possibly leading to delamination or component drift. In automotive, aerospace, or industrial environments, this can’t be ignored.

Another key advantage is manufacturing. During reflow soldering, thermal pads help maintain consistent heating. This improves solder joint quality, avoiding cold joints or solder bridges.

What Is the Function of a PCB Heat Sink Pad?

The core function of a PCB heat sink pad is to pull heat away from the component body. This prevents overheating and promotes reliability. A pad usually sits beneath a hot-running device and connects to a ground or power plane through thermal vias. These vias act like vertical pipes that carry heat down to larger copper surfaces.

Besides thermal performance, the pad also serves mechanical purposes. It supports the component body, helps with proper alignment during placement, and aids in reflow stability. In power ICs, LEDs, and RF modules, such a pad is more than a convenience—it’s a necessity.

Often placed under QFNs, D-Pak, or Power MOSFETs, thermal pads are essential for packages where direct contact to the PCB is required for heat dissipation.

PCB Thermal Pad vs Heatsink

Understanding the thermal pad vs heatsink comparison helps in design decisions. A thermal pad (on PCB) is a built-in copper area, often plated and connected via thermal vias. It is internal and does not add extra height to the device. It’s subtle, efficient, and passive.

PCB Thermal Pad vs Heatsink

A heatsink, on the other hand, is a physical attachment—usually a metal block or finned structure—mounted on top of the component. It dissipates heat through air convection. While highly effective, heatsinks increase weight and require space. They may also need fasteners or thermal paste for better performance.

PCB Thermal Pad vs Heatsink

In low to medium-power circuits, thermal pads do the job silently. When current levels increase or the ambient conditions are harsh, heatsinks may be added. However, both solutions often work together. A pad draws the heat from the chip, and the heatsink then transfers it to the air.

Why Do We Need Thermal Pad on PCB?

We need thermal pads on PCBs to manage heat efficiently within confined board layouts. As chips grow more powerful and boards become smaller, heat density rises. Left unchecked, this can stress the materials, warp the PCB, or trigger thermal shutdowns in sensitive ICs.

Thermal pads provide a compact and cost-effective solution. Unlike external cooling systems, these pads are part of the board design. They reduce the thermal resistance between the component and the ground plane, making heat transfer faster and more efficient.

In LEDs, they stop lumen drop due to temperature spikes. In CPUs or RF amplifiers, they prevent drift in performance. Across industries, from smartphones to satellites, thermal pads are silent protectors against damage caused by thermal fatigue.

Design Consideration of Thermal Relief Pads on PCB

The design of thermal relief pads is not just about placing a copper square under a part. It demands precision. Several factors shape the design.

1. Pad Size: The area should match the component’s thermal tab. Oversized pads can cause solder wicking; undersized ones fail to transfer heat efficiently.

2. Vias Count and Diameter: Vias enhance heat transfer. Placing multiple small vias (0.3mm diameter with 6+holes) within the pad connects it to inner or bottom layers. These must be filled or tented to avoid solder leakage.

Design Consideration of Thermal Relief Pads on PCB

3. Copper Weight: Thicker copper layers enhance thermal conduction. A 2oz or 3oz copper layer works better than standard 1oz in high-heat zones.

4. Solder Mask Clearance: The pad must be free from mask to allow full thermal contact.

5. Connection to Planes: The pad should tie to ground or power plane, depending on the circuit. Use thermal relief spokes when needed to balance heat dissipation and solderability.

6. Component Package Type: Each package, whether QFN or TO-263, demands unique pad sizing and via patterns. Manufacturer datasheets offer recommended layouts—follow them closely.

When to Use Thermal Relief PCB?

Using a thermal relief PCB becomes necessary in several scenarios. One key use is in multilayer boards where copper planes absorb too much heat. Without thermal relief, soldering becomes difficult as heat spreads too quickly. This leads to cold joints or poor wetting.

Thermal reliefs help balance the heat flow. They allow soldering while still ensuring strong thermal performance. Another situation arises with through-hole components connected to large copper areas. Thermal relief spokes prevent the pad from acting like a heat sink during soldering.

Power applications like inverters, motor controllers, and regulators benefit from thermal relief PCBs. So do high-brightness LED arrays. In RF boards, where impedance matters, thermal pads also stabilize the electrical response by providing consistent grounding.

Use them when heat buildup could impair function or reduce board life. Proper relief design improves both manufacturing and operational performance.

What is a Metal Core PCB?

A Metal Core PCB (MCPCB) is a type of printed circuit board that utilizes a metal substrate instead of traditional fiberglass or plastic materials. The main function of a metal core PCB is to provide higher thermal conductivity, which is especially beneficial in applications requiring efficient heat dissipation like LED lights. In a typical PCB, heat can accumulate and negatively affect the performance and lifespan of electronic components. However, the metal core serves as an effective medium for channeling heat away from sensitive areas, optimize the operation and longevity of the circuit.

Metal core PCBs are made with materials like aluminum or copper that allow for effective thermal transfer. They are primarily used in high-power applications, where managing heat is crucial to maintaining the functionality of devices.

What is MCPCB Core Made of?

The core of a Metal Core PCB is typically composed of a metal material that has superior thermal conductivity properties. The most commonly used metals are aluminum and copper, with aluminum being the most popular due to its cost-effectiveness and excellent thermal performance.

  • Aluminum: Aluminum is often the metal of choice for MCPCB cores because it offers a combination of high thermal conductivity, light weight, and affordability. Its relatively low cost compared to copper makes it an attractive option for mass production, especially in consumer electronics and lighting applications.
  • Copper: Copper has a higher thermal conductivity than aluminum and is typically used in more demanding applications that require superior heat dissipation. It is particularly useful in industries like telecommunications and automotive, where components generate significant amounts of heat and need to be efficiently managed.

What Are the Materials Used in Metal Core PCB?

The materials used in Metal Core PCBs are carefully selected to ensure high performance and reliability. The primary materials include:

What Are the Materials Used in Metal Core PCB?
  • Base Material (Metal Core): As mentioned earlier, the core of the PCB is typically made of aluminum or copper. The choice of metal directly impacts the thermal conductivity and cost-effectiveness of the PCB.
  • Insulating Layer: Above the metal core, there is an insulating layer that electrically isolates the metal core from the copper traces on the PCB. This layer is typically made from a thermally conductive dielectric material, such as epoxy resin or fiberglass. The insulating layer ensures that the metal core doesn’t short-circuit the copper traces while still allowing for efficient heat transfer.
  • Copper Foil: The copper foil is used to create the circuit traces. Copper is chosen for its excellent electrical conductivity and reliability. The copper is etched to form the required circuit pattern, allowing electrical signals to flow seamlessly through the PCB.
  • Solder Mask: The solder mask is a protective layer that covers the copper traces to prevent oxidation and improve durability. It also provides electrical insulation to prevent short circuits and ensures that components are properly soldered.
  • Silkscreen Layer: The silkscreen layer is used to print labels, markings, and other necessary information onto the surface of the PCB. This layer aids in component placement during assembly and provides identification for troubleshooting.

Together, these materials form a Metal Core PCB that is capable of efficiently managing heat while ensuring electrical performance and durability.

How Thick is a Metal Core PCB?

The thickness of a Metal Core PCB depends on various factors, including the application’s thermal and mechanical requirements. Typically, the total thickness of a metal core PCB ranges from 1.6 mm to 3.2 mm, but it can vary depending on the design and intended use.

  • Core Thickness: The metal core itself typically ranges from 0.3 mm to 2.0 mm in thickness. Thicker cores provide better heat dissipation but may increase the overall cost of the PCB.
  • Overall PCB Thickness: The overall thickness, including the copper traces, insulating layer, and solder mask, can vary depending on the complexity of the design and the type of components being used. For high-power applications, a thicker PCB may be necessary to ensure adequate heat management and mechanical strength.

How is a PCB Manufactured Step by Step?

The manufacturing of a Metal Core PCB (MCPCB) is a highly specialized process that involves several crucial steps to ensure thermal efficiency, reliability, and electrical performance. Below is a detailed breakdown of each step involved in the MCPCB manufacturing process.

1. Design and Layout Preparation

The first step in the manufacturing of an MCPCB is the design phase. Engineers and designers create the PCB layout, including the placement of components, traces, vias, and pads. This layout must consider factors like thermal management, electrical conductivity, and mechanical strength. The design is usually done using specialized software like AutoCAD or Altium Designer.

In the case of MCPCBs, the layout also includes specific considerations for the metal core, insulating layer, and the heat dissipation needs of the application. The thermal conductivity of the material, as well as the required heat dissipation paths, are factored into the design.

2. Core Material Selection

The next step involves selecting the appropriate core material. For MCPCBs, the core is typically made from metal, usually aluminum or copper. The choice of metal affects both the thermal performance and cost of the PCB.

Aluminum is lightweight, cost-effective while copper has superior thermal conductivity compared to aluminum, and is often used in more demanding applications that require exceptional heat dissipation, such as high-power electronics or automotive applications.

3. Insulating Layer Preparation

Next, an insulating dielectric material is applied to the metal core. This insulating layer is crucial for electrically isolating the metal from the copper traces while still enabling efficient heat transfer. The material used for this layer is typically a thermally conductive resin or fiberglass composite.

The insulating layer’s thickness depends on the requirements of the circuit. It must be thick enough to provide electrical isolation, yet thin enough to allow heat to pass through it efficiently. This layer is typically applied as a thin film or laminate and is then bonded to the metal core using heat and pressure.

4. Copper Foil Lamination

Once the insulating layer is in place, a layer of copper foil is laminated onto the surface. The copper foil is typically bonded to the insulating layer under high pressure and temperature.

Thicker copper foils are used for high-power applications, while thinner foils are sufficient for low-power circuits.

5. Circuit Etching

After the copper foil has been applied, the next step is to etch the circuit pattern. This is done using a chemical etching process, where the unwanted copper is dissolved away, leaving only the copper traces that form the electrical pathways.

The process including apply a photoresist film onto the copper, and then it is exposed to UV light through a mask. The board is then exposed to a chemical solution that etches away the exposed copper, leaving behind the desired circuit pattern.

6. Drilling and Plating

Once the copper traces have been etched, the next step is to drill holes for vias and component leads. Vias are used to establish electrical connections between different layers of the PCB, if applicable. Drilling is done with precision machinery to ensure the holes are accurately positioned.

After drilling, the holes are plated with copper to create electrical connections. The plating process involves depositing a thin layer of copper onto the walls of the drilled holes using an electroplating process. This creates the necessary conductive pathways for signals to travel through the different layers of the PCB.

7. Solder Mask Application

Next, a solder mask is applied to the PCB. The solder mask is a protective layer that prevents oxidation, protects the copper traces from damage. The solder mask is typically a green-colored epoxy-based material, although other colors can be used depending on the customer’s requirements, like red, black, white. Metal core PCB always use white solder mask to gather a good light reflection.

8. Silkscreen Printing

After the solder mask is applied, a silkscreen layer is used to print component labels, markings, and other important information on the surface of the PCB. This is helpful during assembly, as it indicates the proper locations for components to be placed.

The silkscreen printing is typically done using a screen printing process, where ink is pushed through a mesh screen to form the desired markings. Generally, the white solder mask with a black silkscreen, and black solder mask with a white silkscreen.

9. Inspection and Testing

Once the MCPCB has undergone the necessary manufacturing steps, it is thoroughly inspected for defects and tested for functionality. The metal core PCB always must pass three inspection – electrical, thermal, and mechanical requirements.

10. Final Assembly

The final step in the MCPCB manufacturing process is the assembly of electronic components onto the PCB. This involves placing components like resistors, capacitors, LEDs, and other active and passive elements onto the board and soldering them in place.

Component placement is typically done using automated machinery to ensure accuracy and speed. Once the components are placed, they are soldered onto the pads using either wave soldering or hand soldering, depending on the complexity of the design.

11. Quality Control and Shipping

Once the assembly is complete, the final MCPCB undergoes a final functional inspection and quality control check to ensure that it meets the required specifications. The finished product is then packaged and prepared for shipping to customers.

During the quality control phase, the board is examined for any signs of poor soldering, component misplacement, or other issues. If the board passes all inspections, it is ready for shipment.

FAQs

1. Can I design the dielectric layer much thinner on MCPCB?

    Yes you can. Thinner dielectric layer has better thermal conductivity, but also has a lower breakdown voltage

    2. Can you do gold immersion finish on double sided MCPCBs?

    Yes, we can do gold immersion finish on double sided MCPCB, but the price will be less competitive than HASL-LF.

    3. Top 6 factors affecting the final cost of MCPCB?

    1) Board Dimention: For the non-rectangular board, we will calculate the longest two sides, for example, the circle is calculated according to the diameter.

    2) Cu Thickness: The cost will be more expensive if the copper is thicker. We can provide 0.5 OZ, 1.0 OZ, 2.0 OZ, 3.0 OZ, up to 8 OZ.

    3) Thermal Conductivity: The higher the thermal conductivity is, the more expensive the price is. At present, the highest thermal conductivity we can provide is 3W/m.K

    4) Surface Finishing: The common Surface Finishing for MCPCB is HASL_LF, OSP  ENIG (The normal thickness of gold is 1u”). ENIG is more expensive since the finished color is better than other surface Finishing, and it’s easier for components to solder and less prone to oxidation reaction.

    5) Board Thickness: The commonly used thickness is 1.6mm+/-10%, and the thickest we have ever made is 4.0mm+/-10%. The price over 2mm or less than 1mm will be slightly expensive.

    6) Soldermask: White / Black / Blue / Green / Red Oil  (The Taiyo Soldermask is more expensive than normal, the advantage is the reflectivity will be better, which is suitable for LED board.)

    7) Stack up/Construction: The more complex the structure, the more expensive the price, which is mainly executed on your requirements.

    4. Which dielectric layer is recommended for LED (90+W) lighting?

    If it is used for watt more than 90W, considering that the LED power is high, 3W.m.k or 2W/m.k is better than 1W/m.k.

    5. What is Conformal coating of metal core PCB?

    Conformal coating is a specially coating used to protect circuit boards and related equipment from environmental damage. it has good high and low temperature resistance, it can insulation, avoid moisture, leakage, shock, dust and so on.

    One-stop PCB Manufacture And Assembly Service

    What is the difference between PCB manufacturing and assembly?

    PCB manufacturing is the process of creating the board. This includes layering, etching copper, drilling holes, and applying surface finishes. It’s about building the actual platform where your components will sit.

    PCB assembly, on the other hand, places electronic parts on that board. This includes mounting resistors, capacitors, ICs, and connectors. Assembly may use manual or automated methods, depending on the volume and complexity.

    Both stages are vital. Manufacturing builds the structure; assembly brings the board to life. When these are handled by separate vendors, communication gaps may appear. That’s why many turn to a one-stop PCB manufacture and assembly service.

    What is the process of PCB manufacturing?

    PCB manufacturing follows a step-by-step workflow:

    • Design Check: The process starts with verifying your PCB design (Gerber files).
    • Material Selection: The board material (usually FR4, Rogers, or metal core) is selected.
    • Layer Construction: Copper layers are laminated and patterned.
    • Drilling: Holes are drilled for vias and components.
    • Plating and Etching: Conductive paths are formed.
    • Solder Mask and Silkscreen: These protect and label the board.
    • Surface Finish: Finishes like ENIG or HASL are applied.

    Every step needs precision. Errors in early stages may ruin the board. That’s why experienced PCB manufacture and assembly companies use quality control from start to end.

    PCB Manufacture And Assembly

    What is PCB assembly process?

    PCB assembly brings the board into its working form:

    • Solder Paste Application: A stencil is used to apply solder paste to pads.
    • Component Placement: SMT or through-hole components are placed.
    • Reflow or Wave Soldering: Heat melts the paste and fixes parts in place.
    • Inspection: AOI (Automated Optical Inspection) checks for defects.
    • Testing: Functional tests confirm if the board works properly.

    This process can be manual for prototypes or fully automatic for large runs. Choosing a partner with full PCB manufacture and assembly service simplifies coordination.

    PCB Manufacture And Assembly

    What is the difference between a circuit card assembly and a PCB?

    A PCB (Printed Circuit Board) is a blank board with no parts on it. It’s the foundation.

    A circuit card assembly (CCA) is a completed board with all electronic parts installed. This includes ICs, connectors, and other components. In short, a PCB becomes a CCA after assembly.

    Knowing this difference helps avoid confusion when talking to suppliers. When choosing a one-stop PCB manufacture and assembly partner, you get both the board and the assembly done in one place.

    How is a PCB via made?

    Vias connect different layers of a PCB. They’re tiny holes that help route signals across layers.

    Here’s how they’re made:

    • Holes are drilled (mechanically or by laser).
    • The inside of each hole is plated with copper.
    • This connects the layers electronically.

    Types of vias include through-hole, blind, and buried. The right choice depends on your design. Professional PCB manufacture and assembly services help guide that decision.

    PCB Manufacture And Assembly

    What are the cost factors in PCB manufacture and assembly?

    Cost depends on several things:

    • Board Complexity: More layers and smaller traces cost more.
    • Quantity: Larger orders lower the per-unit price.
    • Components: High-end parts can raise the cost.
    • Turnaround Time: Faster delivery adds extra charges.
    • Testing Requirements: More testing increases price but improves reliability.

    While cost matters, value is more important. A reliable PCB manufacture and assembly service saves you from rework and delays.

    Why choose a one-stop PCB manufacture and assembly service?

    Here’s why many customers choose one-stop services:

    • Less Hassle: You don’t need to manage multiple vendors.
    • Faster Delivery: Fewer hand-offs mean quicker results.
    • Better Quality: One team manages all stages, reducing errors.
    • Easy Communication: One point of contact simplifies everything.
    • Cost Efficiency: Integrated services often come with bundled pricing.

              4 Layer PCB Manufacturer, 4 Layer PCB Manufacturer India

              What is a 4 Layer PCB?

              A 4 layer PCB is a printed circuit board with four layers of copper traces stacked together. It includes two outer layers and two internal layers. These internal layers are used for power and ground planes or routing signals.

              Compared to a 2-layer board, this type allows for more routing space and better EMI control. That’s why it’s preferred in applications like embedded systems, communication devices, and consumer electronics.

              Thanks to the additional layers, engineers get more room for complex circuits without increasing the board size. This makes it an excellent choice for compact and high-performance designs.

              4 Layer PCB Manufacturer

              What is the Best Stackup for 4-Layer PCB?

              Stackup matters a lot in any multilayer PCB. For 4 layer boards, the best stackup usually balances signal integrity, EMI control, and manufacturability.
              The standard 4-layer PCB stackup looks like this: Top Layer – Inner Layer 1 – Inner Layer 2 – Bottom Layer. Here’s a common configuration:

              • Top Layer (Signal)
              • Inner Layer 1 (Ground)
              • Inner Layer 2 (Power)
              • Bottom Layer (Signal)

              This arrangement keeps the signal layers next to the planes, which helps reduce noise and crosstalk. In some cases, designers may opt for different configurations based on signal speed or isolation needs. However, grounding between signal layers is one of the most effective ways to ensure signal stability.

              How Thick is a 4-Layer PCB Core?

              PCB thickness is an essential spec. In a 4-layer board, the thickness can vary depending on the prepreg and core materials used.

              A typical 4-layer PCB has a thickness of 1.6mm. This includes the core and prepreg materials between layers. For instance:

              • Core thickness: around 0.8mm
              • Prepreg layers: 0.2mm each
              • Copper foil: 35”m or thicker depending on current requirements

              If your design needs specific mechanical properties, you can go thicker or thinner. Many 4 layer PCB manufacturers offer customization for thickness. So, whether you’re working with handheld devices or industrial-grade equipment, there’s a solution that fits.

              4 Layer PCB Manufacturing Process

              The process of making a 4-layer board is more complex than single or double-layer boards. But it allows for higher performance. Here’s a quick walk-through:

              Step-by-Step Overview:

              Inner Layer Imaging and Etching

              • The manufacturer starts with laminates. Patterns are transferred to the inner layers using a photoresist. Then, copper is etched away to form the desired traces.

              Layer Lamination

              • The etched inner layers are stacked with prepreg material and outer copper foils. This sandwich is then laminated under high heat and pressure.

              Drilling

              • Holes are drilled to connect the layers, including vias that link top to bottom.

              Plating

              • The drilled holes are electroplated with copper to ensure conductivity across layers.

              Outer Layer Imaging and Etching

              • Similar to the inner layer, patterns are added to the outer surfaces and etched.

              Solder Mask and Surface Finish

              • A protective solder mask is applied. Then, finishes like HASL, ENIG, or OSP are added to the pads for better solderability.

              Silkscreen Printing and Testing

              • Component labels are printed. Finally, every board goes through electrical testing to ensure performance.

              This process ensures the board meets all functional and quality standards. A professional 4 layer PCB manufacturer maintains tight control during each step to avoid issues later.

              How Much Does a 4 Layer PCB Manufacturer Charge vs 6 Layer?

              Pricing always plays a major role. The cost of a 4-layer board depends on materials, size, and volume. On average, a 4-layer PCB may cost 25%–50% less than a 6-layer PCB of the same dimensions. Here’s why:

              • Material use: Fewer layers mean less copper and prepreg.
              • Processing time: Less time required for pressing and drilling.
              • Testing cost: 6-layer boards need more in-depth electrical testing.

              For basic 4-layer boards, pricing can start at $50–$100 per square meter for large batches. Complex designs or special materials may push it higher. That said, when you’re scaling production, the per-unit cost drops quickly.
