Why is Aluminium Used in Circuit Boards?

Aluminum can actually transfer heat away from vital components, thus minimizing the harmful effect it could have on the circuit board. Higher durability: Aluminum provides strength and durability to a product that ceramic or fiberglass bases cannot.

Structure of Aluminum PCB

Aluminum PCBs are aluminum based CCLs (CCL is a type of base material of PCBs). AluminumPCBs are actually quite similar to FR4 PCBs. The basic structure of Aluminum PCBs is four layered. It consists of a layer of copper foil, a dielectric layer, an aluminum base layer and aluminum base membrane.

Copper Foil Layer: the copper layer used is relatively thicker than normal CCLs ( 1oz-10oz). A thicker layer of copper means a larger current carrying capacity.

Dielectric Layer: the Dielectric layer is a thermally conductive layer and is around 50μm to 200μm thick. It had a low thermal resistance and it suitable for its application.Aluminum Base: The third layer isthe aluminum base which is made up of aluminum substrate. It has a high thermal conductivity.Aluminum Base Membrane Layer: Aluminum base membrane is selective. It has a protective role by keeping the aluminum surface safe from scraping and unwanted etching. It is of two types i.e. Lower than 120 degree or around 250 degrees (anti high temperature).

WHAT IS AN ALUMINUM PCB?

A PCB generally consists of three layers. A conductive copper layer at the top, a dielectric layer in between, and a layer of a substrate at the bottom. Standard PCBs have a substrate layer made of fiberglass, ceramic, polymers, or any other non-metal core. An ample amount of PCBs uses FR-4 as the substrate.

Aluminum PCBs use an Aluminum substrate. Instead of standard FR-4 as the substrate material.

Circuit Copper Layer

This layer transmits signals over the entire PCB board.

The movement of charged particles generates heat.

This heat is transferred to the Aluminum substrate. Which dissipates it efficiently.

Insulating Layer

This layer is also known as the dielectric layer.

It is made of materials that are poor conductors of electricity.

It absorbs the heat generated in the above layer. And transfer it to the Aluminum substrate below it.

Substrate

The substrate acts as a foundation for the PCB.

It firmly holds the components above it. By changing the characteristics of the substrate, the performance of PCB varies.

For example, a rigid substrate provides strength and durability to the PCB board.

While a flexible substrate opens up more design options.

The aluminum substrate is used in power electronics-based applications where high thermal dissipation is required.

Due to its good thermal conductivity, it keeps heat away from vital electronic components. Thus ensuring minimal circuit damage.
