Advantages of Metal Core PCB

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.
