Metal Core PCB

In recent years, the LED industry has been rapidly developed, but the problem of heat dissipation has been puzzling the application and development of LED, especially high-power LED in the field of lighting. The application of metal substrate provides a new way to solve the heat dissipation of LED effectively.

Metal Core PCB, abbreviated as MCPCB, is made of the thermal insulating layer, metal plate, and metal copper foil, which has special magnetic conductivity, excellent heat dissipation, high mechanical strength, and good processing performance. For metal core base material, there are aluminum and copper base materials. An aluminum substrate is a kind of metal-based copper clad plate with good heat transferring and dissipation function. The copper substrate has better performance than aluminum, but its price is relatively more expensive than aluminum.

Clients order aluminum PCBs more often because the price of aluminum PCB is much more economic, they are used for LED lighting, audio frequency apparatus, and communication electronic equipment.
