A Metal Core PCB (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 Metal Core 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 core. Base metals in the Metal Core PCB are used as an alternative to FR4 or CEM3 boards.
