Product Details

Aluminum PCB is a unique layered system consisting of the following layers (circuit layer, dielectric layer, base layer).
Printed circuit foil, from 1 ounce to 5 ounces thick.
There are many different options for the dielectric layer to provide electrical isolation and minimal thermal resistance. It is also used to bond the circuit layer and the substrate together.
The base layer is usually aluminum, but it can also be copper. Although there are many alternative thicknesses, the most common thickness is 0.040 inches (1.0 mm).
