PCB aluminum based circuit board

PCB aluminum based circuit board has good thermal conductivity, electrical insulation and machining performance. PCB aluminum substrate is composed of circuit layer, thermal insulation layer and metal substrate; The metal base is the support component of aluminum substrate, which requires high thermal conductivity. Generally, it is aluminum plate, which is suitable for conventional machining such as drilling, punching and cutting.

1. PCB aluminum substrate can reduce the temperature, improve the power density and reliability of products, and extend the service life of products;
2. PCB aluminum substrate can reduce the volume, hardware and assembly costs;
3. PCB aluminum substrate can replace ceramic substrate to obtain better mechanical endurance.

 
There are generally four kinds of aluminum based plates, mainly because the thermal conductivity of aluminum is different. The higher the thermal conductivity is, the more expensive the price is. It is mainly used for audio equipment, power supply equipment, communication electronic equipment, high frequency amplifier, filter, electric appliance, transmitting circuit, office automation equipment, motor driver, etc., automobile, electronic regulator, igniter, power controller, computer, CPU board, floppy disk driver, power supply device, etc.
