Metal Core & Metal Back

metal back pcb printed circuit board
Heat dissipation, metal core (MCPCB) is thermally conductive. The most common material is an aluminum and copper alloy – used as a thermally conductive dielectric layer.This allows air to escape, and eliminates the need for multiple heat sinks on top surface-mounted components. Excellent attributes for metal-backed PCB layout include grounding, heat dissipation and rigidity.
