MC PCB (you also can call it Metal Core PCB, Aluminum PCB, Metal-Based PCB) is a kind of PCB board with metal base material instead of woven glass FR4, FR3, or others. There is a single-sided, double-sided, and multilayer board. The most of MC PCB Manufacturers are commonly used metal core material is aluminum, copper, and alloy. Aluminum Based PCB is the most frequently used among them due to its good heat transfer ability, dissipation ability and relatively cheaper costs than copper, even which may have better performance, we are high thermal conductivity PCB suppliers in china and Chinese Customized OSP Surface Finish MCPCB Metal Based PCB Factory.

Metal-Based 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.

Metal Core PCB (MC PCB) feature:

Effective treatment of thermal diffusion in PCB circuit design.
Reduce operating temperature, increase power density and reliability, extend the life of the product.
Smaller footprint, lower hardware, and assembly costs.
Replace the fragile ceramic substrates PCB with better mechanical durability.
