MCPCB, Aluminium PCB, or call LED PCB are the circuit boards which use a base metal material as the heat spreader portion of the printed circuit board, Aluminum PCB has good thermal conductivity, electrical insulation and mechanical processing properties, it's the most excellent and cheap cooling solutions.

MCPCB/Metal core PCB 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 PCB transfer heat 8 to 9 times faster than Rigid FR4 PCB. MCPCB laminates dissipate heat, keeping heat generating components cooler which results in increased performance and life. Metal core PCB are most widely found in LED technologies, using a metal core PCB in these LED products and applications help to greatly reduce the heat emitted.

A-TECH Circuits has been working with Metal PCB/LED PCB for several years. We have gained extensive knowledge and experience in manufacturing Aluminum PCB from single-sided to double-sided which mainly used in LED lighting industry.
