MCPCB & Metal Core PCB & LED PCB

Advanced PCB Solutions

MCPCB, Aluminium PCB, or LED PCB are circuit boards which use a base metal material as the heat spreader. Aluminum PCB has good thermal conductivity, electrical insulation and mechanical processing properties.

MCPCB / Metal core PCB integrates a dielectric polymer layer with high thermal conductivity. Metal core PCB transfers heat 8–9 times faster than FR4 PCB.

Nexay has extensive experience manufacturing Aluminum PCB from single-sided to double-sided, mainly used in LED lighting industry.
