Flexible
Flexible Aluminum uses a different technique to provide great insulation. It uses a combination of ceramic fillers along with Polymide resins for insulation purposes. Due to this combination, the manufacturer enjoys aluminum thermal conductivity while retaining the flexibility feature.
Hybrid Aluminum
As the name suggests, it is basically a merger of aluminum with a non-thermal material. The hybrid aluminum uses FR4, which acts as a non-thermal material. Doing this makes it possible for the manufacturer to offer all the supreme thermal conductivity while retaining the rigidity of the Printed Circuit Boards.
Multi-Layer Aluminum
For highly complex Printed Circuit Boards, multi-layer aluminum is an excellent choice due to its outstanding and amazing thermal conductivity. You will not find a heat conductor better than a multi-layer aluminum.
