Product Description: Aluminum PCB, also known as Aluminum Clad PCB, is a printed circuit board made of aluminium metals and other non-conductive materials. It is highly efficient in heat dissipation with its excellent thermal conductivity. Aluminum PCB has a layer of 1-4 mils, and the copper thickness is 1oz. It has surface finish of HASL, but without impedance control. The circuit board is lightweight, yet strong and reliable, making it ideal for a variety of applications.
