Types of Aluminum PCB:

There are a number of types of aluminum PCBs which are used in many applications based on their construction and design. However, the main purpose of all the aluminum PCBs is almost the same; providing heat dissipation solutions for applications involving high temperature. Following are the main types of aluminum PCBs.

1. Hybrid Aluminum PCB

In hybrid aluminum construction, non-thermal material is processed and refined separately before it is applied to the thermal materials with an aluminum base.

The most common practice is developing 2 layers or 4 layers structure that comprises of FR4 material normally.

A non-thermal material that is bonded with thermal material and the aluminum base provides rigidity and helps in the dissipation of heat.

This non-thermal bonding is preferred over using all thermal materials because it features less cost and encompasses efficient thermal conductance over regular FR4 products.

No heat sinks or assembly steps are required for the development of this product.

Through-hole components can be easily adjusted using component windows on the aluminum base.

This helps in passing the cables and connectors through the substrate. Also, the seal created by the solder fillet eliminates the need for costly adapters.

2. Multilayer Aluminum PCBs are very common in power supply products and come with multiple layers of thermally conductive dielectrics.

These materials are very useful when they are combined with one or more layers of circuitry in which thermally conductive dielectric is buried between the layers with the help of blind vias which also act as a signal or thermal vias.

Single-layer construction of these designs is not very effective, however, when they come with more complex designs they provide an ideal solution for many applications involving heat dissipation.

3. Through-Hole Aluminum PCB

When it comes to most complex constructions, a single layer of aluminum is back-filled and pre-drilled with before applying lamination, forming a Core of multilayer constructions.

Thermal bonding materials are then used to laminate the thermal materials on both sides of the aluminum.

Once lamination is done, drilling is applied to the assembly.

In order to maintain proper electrical insulation, the plated through holes created as the result of drilling must pass through aluminum clearances.
