Aluminium PCB Advantage:

 1.  Dissipation of heat without using additional heatsinks.

 2.  Mechanically rigid, increasing the physical strength of the assembly

 3.  Reduces the effect of thermal stress on all components, increasing life and durability

 4.  Improved thermal conduction leading to versatility in component and tracking layout enabling PCB dimensions to be reduced.

 5.  Reduces component operating temperatures, improving reliability.

 6.  Substrate aluminum can be drilled / machined and routed, aiding PCB mounting
