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.
Advantages and Disadvantages of Aluminum PCB
Aluminum boards are one of the most thermally conductive PCB options. They keep as much heat away from vital components as possible to ensure minimal circuit damage. Thanks to their high heat tolerance, they can handle higher density circuits and larger power levels. Substrates created from aluminum alloys have a high level of physical durability that lowers the risk of breakage. Compared to other metals, aluminum has a lower environmental impact in addition to a reasonable cost.
On the other hand, aluminum PCBs tend to have more niche uses than standard boards. While they cost less than adding conductors to a copper board, they have a higher price than standard PCBs without those components. Investing in an aluminum core may not pay off if your application doesn’t involve high temperatures. If you plan on creating a flex circuit, an aluminum flex PCB can only flex into its initial position. It will bend to fit into smaller electronics, but it won’t withstand the stress of vibration.
