Overview of Aluminum Substrate

Among all metal core PCBs, aluminum core PCBs are the most common type. The base material consists of an aluminium core and standard FR4. It features thermal cladding to efficiently dissipate heat while cooling components and improving the overall performance of the product. Currently, Aluminum Backed PCBsare considered the solution for high power and tight tolerance applications.

Advantages of aluminum substrates

1. Environmental protection: Aluminum is non-toxic and recyclable. Manufacturing with aluminum also benefits energy savings because it is easy to assemble. For printed circuit board suppliers, using this metal helps maintain the health of our planet.

2. Heat dissipation: High temperatures can cause serious damage to electronics, so it is wise to use materials that help dissipate heat. Aluminum can actually transfer heat away from vital components, minimizing the detrimental effect it can have on the circuit board.

3. Higher Durability: Aluminum provides the product with strength and durability that a ceramic or fiberglass base cannot. Aluminium is a strong substrate that reduces accidental breakage during manufacturing, handling and everyday use.

4. Lightweight: Aluminum is a surprisingly lightweight metal with incredible durability. Aluminum adds strength and resilience without adding any extra weight.
