Metal Core PCB

Metal Core PCB – Printed Circuit Boards with thermal management

We have been working with customers from industries like automobile, lighting, power conversion and have witnessed the rise of LED based products. With the exponential increase in the LED usage, MCPCB demand has also grown. In fact, it is one of the fastest growing PCB segments. Metal Core Printed Circuit Boards (MCPCB) or a Thermal PCB is a type of PCB that contains a base metal material to redirect heat away from the components.

CCI has been empowering its customers to innovate for the last two decades and we have adopted new technology to manufacture MCPCB with thermal management. MCPCBs are also known as thermal clad PCBs, insulated metal PCBs (IMPCB), insulated metallic substrate (IMS), and metal-clad PCBs.

MCPCB are not the epoxy glass PCB. Aluminum is the most preferred base material for the copper circuit layer and a layer of thermal conductive dielectric. We mostly use Aluminum as a metal core.


Basic Structure of MCPCB manufactured by CCI Canadian Circuits:

  • Metal core layer
  • Dielectric layer
  • Heat Sink
  • Copper Layer
  • Circuit layer
  • Solder Mask

Advantages of Metal Core PCB (MCPCB)

  • High thermal Conductivity, lower thermal impedance
  • High heat transfer rate, keeps the components cooler
  • Ideal for Surface Mounted components
  • Soldermask is white – for use in LED
