PCB Global manufacture 1 layer, 2 layer and the high tech 4 layer Aluminium PCB’s for the worldwide electronics manufacturing industry.  A standard Aluminium Printed Circuit Board stack up for 1, 2 and 4 -Layer PCB’s is shown below:

Base Metal Layer:  Aluminium – generally 1.0 to 4.0mm 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; 1W/m-k and 2W/m-k being the standard.

Copper Foil:  The copper foil will be processed and etched to the required circuit layer design.
