Aluminium Printed Circuit Boards
Posted on 25/09/2015

PCB Global manufacture 1 layer, 2 layer and the high tech 4 layer Aluminium PCB’s for the worldwide electronics manufacturing industry. Applications for Aluminium PCB’s are found predominantly in the lighting, motor drives, relays, automotive, power conversion and 3D printer industries. Using Aluminium PCB Technologies assists in lower equipment operating temperatures which improves the LED’s with consistent colour and brightness, in turn, increasing the LED component life.

For solid state relays Aluminium PCB’s offer great thermal efficiency and are mechanically robust for all heavy industry applications. The correct dielectric choice will also provide the electrical isolation required to maintain operating parameters and meet safety regulations as well. Currently 80% of all Aluminium PCB’s are manufactured as 1 layer with the lighting industry being the largest consumers.

The stack as illustrated below consists of:

Base Metal Layer:Aluminium – generally 1.0 to 2.0mm thickness, 1.5mm being the standard.

Dielectric Layer:Not only to bond the copper circuit layer to the aluminium but more importantly offer the required electrical isolation with minimal thermal resistance.

Copper Foil:As per any standard printed circuit board, the copper foil will be processed and etched to the required circuit layer design.
