Aluminium Core PCB

Aluminium Core PCB is a metal-based copper clad laminate with good heat dissipation function. Generally, the single panel is composed of a three-layer structure, which is a circuit layer (copper foil), an insulating layer and a metal base layer. Also used for high-end use is designed as a double panel, the structure is circuit layer, insulation layer, aluminum base, insulation layer, circuit layer. A very small number of applications are multi-layer boards, which can be made of ordinary multi-layer boards combined with an insulating layer and an aluminum base.

The material of the circuit board is aluminum alloy. In the past, the material of our general circuit board was glass fiber, but because the LED heat is large, the circuit board for LED lamps is generally Aluminum substrate, capable of fast heat conduction.

Aluminium Core PCB Characteristics

With good thermal conductivity, electrical insulation performance and machinability, the Aluminium Core PCB has the same thickness and the same line width compared with the conventional FR-4. Also, it can carry higher current and can withstand voltage 4500V, thermal conductivity greater than 2.0, mainly based on Aluminium Core PCB in the industry

 

• Extremely efficient treatment of thermal diffusion in circuit design;

• Reduce product operating temperature, increase product power density and reliability, and extend product life;

• Reduce product size and reduce hardware and assembly costs;

• Replace the fragile ceramic substrate for better mechanical durability.

Aluminium Core PCB plates are commonly used for aluminum substrates, mainly including 1000 series, 5000 series and 6000 series.
