Aluminum PCB: The Ultimate Guide to Manufacturing, Features, Advantages, and Selection



Aluminum PCB

minum PCBs, also known as Aluminium-based PCBs or Alu-PCBs for short, are a type of printed circuit board that utilizes an aluminum substrate instead of the traditional epoxy or fiberglass materials. This unique construction offers several advantages over standard PCBs and makes them ideal for various applications in the electronics industry.

Manufacturing Process

The manufacturing process of Aluminum PCBs involves several steps. Firstly, a thin layer of thermally con Multilayer PCB ductive dielectric material is bonded to the aluminum base. Next, a copper layer is added using methods like printing, etching or plating. Multiple layers can be created by repeating this process with different dielectric and copper layers. Finally, the board undergoes surface finishing and solder mask application.
