As PCB supplier china knows that, like other printed circuit boards, aluminum PCB boards comprise a circuit layer, a thermal insulation layer, and a base layer.

Circuit Layer – The circuit layer in an aluminum PCB is made using copper foil. Typically, this layer is slightly thicker than a standard circuit board, allowing the board to carry a larger current.

Dielectric Layer – A layer of thermally conductive material insulates the board from stress caused by heat. This layer is often made of ceramic polymer sandwiched between the circuit and base layers.

Base Layer – An aluminum PCB has a base layer made from an aluminum alloy substrate, which has high thermal conductivity and is ideal for electronics that create high heat levels.
