What is a Metal Core PCB (MCPCB)?
A Metal Core Printed Circuit Board (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.

PCBs that require a lot of power usually generate a lot of heat. If your PCBs need fast cooling it is better to use Metal Core PCB than FR4. The following list includes some of the most popular applications that work great with this technology:
■LED Lighting
■Power Conversion Systems
■Power Supplies
■Telecom & Industrial
■Automotive Electronics
