What is Metal Core PCB?

MCPCB Metal Core or Metal Clad PCB Boards, also known as a thermal PCB or metal-backed PCB, is a specialised type of PCB designed to improve the thermal performance of electronic components by using a metal base material for its heat spreader layer.

This layer usually consists of either aluminium or copper, providing superior conductivity and dissipation capabilities compared to traditional PCBs. The metal layer covers one side of the PCB and helps to dissipate heat away from the components, ensuring optimal performance and reliability.

Metal Core PCB Manufacturing Process:

  1. Step 1: Material Selection. The metal core material used for MCPCB fabrication must be chosen according to the application requirements. This includes the metal core (typically aluminium or copper) and the dielectric material, usually a fibreglass-filled epoxy laminate.
  2. Step 2: Drilling. The next step in manufacturing an MCPCB is the drilling of the layers. The holes in the material must be drilled accurately to ensure that all components fit properly when assembled.
  3. Step 3: Dry Film Image Transfer. Once the board is drilled, it needs to be prepared for imaging. This includes applying a layer of photo-sensitive dry film that will transfer the desired layer design onto the board.
  4. Step 4: Solder Mask. An additional layer of solder mask is then applied to protect the surface from oxidation and provide a protective coating for the components.
  5. Step 5: Routing. Once the image has been transferred, it needs to be precisely routed to create connections between components on the board.
  6. Step 6: V-Cut. The next step in the process is to create a V-cut or two intersecting cuts that remove the excess material from the edges of the board.
  7. Step 7: Test. After all, the components have been assembled and connected, and it’s time for testing. At this stage, tests are conducted to ensure the board functions correctly.
  8. Step 8: HiPot. Finally, a high-potential (HiPot) test is performed to check for any shorts between components on the board. This test also verifies that all connections are secure and that no leakage current exists. After successfully completing this final test, the board is ready for shipment.

Benefits of Metal Core PCB India:

    • Improved Heat Dissipation: Metal core PCBs are much more efficient at dissipating heat than their traditional counterparts, making them well-suited for applications with high power requirements.
    • Increased Reliability: The metal core used in manufacturing helps reduce expansion and contraction due to temperature variations, leading to improved reliability and long-term performance.
    • Reduced Cost: The cost of producing MCPCBs is typically lower than traditional PCBs due to the shorter production times and reduced number of components and materials required. This can translate into cost savings for manufacturers needing large boards.
    • Improved Electrical Performance: Metal core PCBs are more effective at conducting electricity, allowing components to be placed closer together and enhancing signal integrity. This can lead to improved electrical performance and reduced risk of interference.
    • Better Strength and Stability: The metal core adds additional strength and stability to the board, making it both more durable and less likely to deform over time. This can reduce maintenance needs and extend the lifetime of your MCPCB.
    • Improved Design Flexibility: Due to their improved thermal performance, MCPCBs allow for greater design flexibility when compared to traditional PCBs. This can lead to more efficient designs that are better suited for high-power applications.
    • Longer Lifetime: MCPCBs have a longer lifespan than traditional PCBs and are often more reliable when exposed to harsh environments. This can help manufacturers save on costs associated with frequent repairs or replacements over time.
