Metal Core PCB

Your Trusted Metal Core PCB Manufacturer

GCS has extensive experience in manufacturing and developing new technologies in the MCPCB markets.

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.
