Aluminium PCB Advanced Circuits Specification
Among all Metal core PCBs (aka MCPCBs, known for their ability to provide effective thermal dissipation for electronic products), Aluminium PCBs is the most common type – the base material consists of aluminium 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. Currently, Aluminium Backed PCBs is regarded as the solution to high power and tight tolerance applications.
