Structure of Aluminum PCBs
Aluminum PCBs are actually quite similar to FR4 PCBs. The basic structure of Aluminum PCBs is four layers. It consists of a dielectric layer, copper foil, an aluminum base layer, and an aluminum base membrane.
• Copper Foil Layer
The used copper layer is relatively thicker than normal CCLs (1oz to 10oz). A thicker layer of copper means a larger current carrying capacity.
• Dielectric Layer
The Dielectric layer is a thermally conductive layer and is around 50micrometer to 200micrometer thick. It has a low thermal resistance and it is suitable for its application.
• Aluminum Base
This third layer is the aluminum base that is made up of aluminum substrate. It has high thermal conductivity. Aluminum Base Membrane Layer
The aluminum base membrane is selective. It plays a defensive role by keeping the aluminum exterior safe from unwanted etching and scraping. It is of two types i.e. around 250 degrees or lower than 120 degrees (anti-high temperature)
