Aluminum PCB

Aluminum PCB

Metal core PCB provides effective thermal dissipation for electronic products. Aluminum printed circuit board is most commonly used in metal core PCBs; the base material is aluminum core with standard FR4. The thermal aluminum clad layer dissipates heat efficiently, cool components and increase the performance of products. They are widely used in LED lights, power equipment, automotive systems, etc.
