What is a Metal Core PCB ?

Metal core aluminum PCB is an aluminum-based copper clad laminate with good heat dissipation function. Generally, the single layer aluminum-based PCB is composed of a three-layer structure, which is a circuit layer (copper foil), an insulating layer and a metal base layer. Also used for high-end use is designed as a double sided and multilayer aluminum PCB.

A metal core PCB is a special PCB having a metallic base layer. This base layer is usually made of aluminum or copper. As it contains a metallic layer, it is named Metal Core PCB (MCPCB).

An aluminum PCB is a printed circuit board that contains a thin layer of conductive dielectric material. They are also called aluminum cladding, aluminum base, MCPCB (metal clad printed circuit board), IMS (insulated metal substrate), thermal conductive PCB, etc. Aluminum PCBs were developed in the 1970s, and soon their applications increased sharply. The first application is their use in amplifying hybrid integrated circuits. They are being used on a large scale, so we must understand aluminum PCB and its importance.
