Aluminum PCB has three main layers as follows:
☆Circuit Layer: Printed circuit foil with thickness of 1 oz to 10 oz.
☆Dielectric Layer: The Dielectric layer is a thermally conductive layer and is around 50μm to 200μm thick. It had a low thermal resistance and it suitable for its application.
☆Base Layer: The base layer is most often Aluminum but can also be copper. The most commonly used thickness is 0.040" (1.0mm) although many alternative thicknesses are available.
