Aluminum PCB

 

Aluminum PCB is a metal-based CCL(Copper Clad Laminate) with good heat dissipation ability. Generally, PCB consists of three layers, namely the circuit layer(copper foil), the insulating layer, and the metal substrate. For high-end applications, it is also designed for double-layer boards, whose structure is the circuit layer, the insulating layer, the aluminum base, the insulating layer, and the circuit layer. There are few applications of multi-layer boards, and they can be made by bonding ordinary multi-layer boards with insulating layers and aluminum substrates.

 

Advantages:

1) Protect the environment: Aluminum is non-toxic and recyclable. Since aluminum is easy to assemble, it helps save energy.

2) Heat dissipation: High temperature can seriously damage electronic devices. Aluminum can help components to dissipate heat, thereby minimizing the harmful effects(heat) on circuit boards.

3) Durability: Aluminum has the strength and durability that ceramic or glass fiber substrate cannot provide, which can reduce accidental damage during manufacturing, handling, and daily use.

4) Lightweight: Aluminum is a surprisingly lightweight metal. Aluminum adds strength and elasticity without adding any extra weight.

 

 

Application:

The biggest advantage of aluminum PCB is its excellent heat dissipation efficiency. It transfers heat and rapidly cools the components, which can improve the overall performance of the final product. Therefore, aluminum PCB is an ideal solution for high-density and high-power products (such as LED applications, power supplies, computers, etc.).
