Aluminum PCB Advanced Circuits Specification
Among all Metal core PCBs ,Aluminum PCBs is the most common type - the base material consists of aluminum core with standard FR4. It features a thermal clad layer that dissipates heat in a highly efficient manner, while cooling components and increasing the overall performance of the products.
