Aluminum PCB
Aluminum PCB Advanced Circuits Specification
Among all Metal core PCBs (aka MCPCBs, known for their ability to provide effective thermal dissipation for electronic products), 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. Currently, Aluminum Backed PCBs is regarded as the solution to high power and tight tolerance applications.
GreenPCB’s been manufacturing aluminum PCBs for 10+ years. Our full feature aluminum circuit boards making capabilities and Free DFM Check allow you to get high-quality aluminum PCBs done within budget. Our printed Aluminum PCBs are widely used for LED lighting, power equipment and automotive systems.
