Metal Core PCB MCPCB is kind of PCB with metal base material instead of woven glass (FR4), cotton paper (FR3) or others. It is with single layer metal core PCB, double layers MCPCB, double sided MCPCB, COB MCPCB and multilayer MCPCB. The common used metal core is aluminum, copper and alloy. Aluminum is the most frequently used among them due to its good heat transfer ability, dissipation ability and relatively cheaper cost than copper, although which may has a better performance.

Single Layer Metal Core PCB MCPCB consists of a metal base (aluminum or copper alloy), dielectric layer, and copper conductor layer. The single layer MCPCB can be used with surface mount and chip & wire components, and provides much lower thermal resistance than FR4 PCB. The metal core provides lower cost and allows much larger areas than ceramic substrates.

Metal Core PCB is used to replace traditional FR4 or CEM3 PCBs because of the ability to efficiently dissipate heat away from the components. This is achieved by using a thermally conductive dielectric layer.

The prepreg dielectric provides excellent heat transfer from the foil and components to the base plate, while maintaining excellent electrical isolation. The base aluminum/copper plate gives the single-sided substrate mechanical integrity, and distributes and transfers the heat to a heat sink, mounting surface or directly to the ambient air.

Metal core PCB feature:

1. Use of surface mount technology (SMT)
2. Effective treatment of thermal diffusion in PCB circuit design

3. Reduce operating temperature, increase power density and reliability, extend the life of product
4. Smaller footprint, lower hardware and assembly costs
5. Replace the fragile ceramic substrates PCB with better mechanical durability.
