What is a Metal Core PCB (MCPCB)?
MCPCB also known as a thermal PCB or metal backed PCB, is a type of PCB that has a metal material as its base for the heat spreader portion of the board. The thick metal (almost always aluminum or copper) is covering 1 side of the PCB. Metal core can be in reference to the metal, being either in the middle somewhere or on the back of the board. The purpose of the core of an MCPCB is to redirect heat away from critical board components and to less crucial areas such as the metal heatsink backing or metallic.
The Advantages of MCPCB
*MCPCBs can be advantageous to use for their ability to integrate a dielectric polymer layer with a high thermal conductivity for a lower thermal resistance.
*Metal core PCBs transfer heat 8 to 9 times faster than FR4 PCBs. MCPCB laminates dissipate heat, keeping heat generating components cooler which results in increased performance and life.
