Structure of Aluminum PCBs:
The structure of a basic Aluminum PCB is that of a Copper Clad
Laminate (CCL) backed with an Aluminum base. A Copper foil and a
dielectric layer make up the CCL. The Aluminum base may have an
additional Aluminum base membrane as a protection.

Copper Foil Layer: Manufacturers generally use the same Copper foil
as they use for regular FR-4 boards, unless the applications demand
large current carrying capacity. For the latter, they use
relatively heavy copper, with thickness varying from 1 to 10
ounces. The inner side of the Copper foil goes through a typical
Zinc and Brass plating to improve its peel-off strength, while the
top surface undergoes a chemical treatment to prevent oxidation.
Dielectric Layer: The thickness of this layer varies from 50 to 200
um, and forms the core technology of the Aluminum PCB. The
dielectric layer has excellent thermal conductivity, low thermal
resistance, and high electrical insulation properties. It also has
excellent anti-thermal aging properties and can withstand thermal
and mechanical stress.
The structure of the dielectric layer depends on the application.
For instance, Universal Aluminum PCBs use a pre-preg of epoxy glass
fiber as a dielectric layer, special Aluminum PCBs use resins of
high thermal conductivity, and High-Frequency Aluminum PCBs use a
dielectric layer with a prepreg of Polyimide or Polyolefin resin
glass fiber.
Aluminum Base Layer: This is an Aluminum substrate material acting
as the supporting component. Along with high thermal conductivity,
the base layer must be suitable for regular mechanical
manufacturing processes including cutting, punching, and drilling.
