They are PCBs that have a layer or layers of silkscreen, solder mask, and copper coat. Also, these aluminum PCBs come with metal substrates instead of a plastic substrate or fiberglass material.
The base material of aluminum PCB comes with the regular FR4 and an aluminum core. Also, aluminum PCBs are usually an ideal solution for tight-tolerant and high-power devices.
Hence, the PCB comes with a thermal layer that is clad and efficiently dispels heat. In summary, aluminum PCB’s presence helps to cool down components and increases electronic devices’ performance.
