General Information About Metal Core PCB

As Metal Core PCB means the base material for PCB is metal, but not normal FR4/CEM1-3, etc, and currently what the metal used are Aluminum, Copper alloy. MCPCBs are used instead of traditional FR4 or CEM3 PCBs because of the ability to efficiently dissipate heat away from the components. This is achieved by using a Thermally Conductive Dielectric Layer.

The main difference between a FR4 board and MCPCB is the thermally conductive dielectric material in the MCPCB.

Advantage of MCPCB

1.heat dissipation

 The purpose of a MCPCB is to efficiently remove the heat from all topical IC's (not just LEDs). The aluminum base and thermally conductive dielectric layer act as bridges between the IC's and heat sink. One single heat sink is mounted directly to the aluminum base eliminating the need for multiple heat sinks on top of the surface mounted components.

2. thermal expansion

Thermal expansion and contraction is the common nature of the substance, different CTE is different in thermal expansion. As its own characterics, aluminum and copper have unique advance than normal FR4, thermal conductivity can be 0.8~3.0 W/c.K.

 

Application of MCPCB

LED

High-current LED, high-current PCB

Industrial power equipment
