Rush PCB makes Aluminum PCBs, the most popular among metal core boards. Our aluminum substrate PCBs use the aluminum core as the base material and standard FR4 over it. The aluminum base acts as a thermal clad layer for dissipating heat efficiently, keeping heat-producing components cool, thereby increasing the overall performance of the board and the device. Among all the aluminum-based PCB manufacturers, our customers consider our aluminum PCBs as the most useful solution to high-power applications.
