An aluminum substrate is a kind of metal base with a good ability to dissipate heat. Generally, a single panel is composed of three layers of structure, namely the circuit layer (copper foil), the insulation layer and the metal base layer. For high-end use, there are also designed as double panels, structure for the circuit layer, insulation layer, aluminum base, insulation layer, circuit layer. Among them, the PCB aluminum substrate has excellent thermal conductivity, electrical insulation properties and mechanical processing properties.

Today, the aluminum based PCB has been widely used in the market for its low price and good quality. In the content below, we will provide you some reasons for choosing the aluminum based PCB.

Here is the content list:

1. The features of the aluminum based PCB.

2. The advantages of the aluminum based PCB.

1. The features of the aluminum based PCB.

The core technology of the PCB aluminum substrate is the thermal insulation layer, which is generally composed of a special polymer filled with special ceramics. It has a low thermal resistance and thermal aging resistance. The aluminum based PCB can withstand mechanical and thermal stress. The metal base layer is the supporting member of the aluminum substrate. It is suitable for conventional machinings such as drilling, punching and cutting.

2. The advantages of the aluminum based PCB.

First of all, compared with the traditional FR-4, the aluminum based PCB can reduce the thermal resistance to the minimum, so that the aluminum substrate has excellent thermal conductivity; Compared with the thick film ceramic circuit, its mechanical properties are very good.

Second, the aluminum based PCB is more environmental-friendly. It can reduce the assembly of radiators and other hardware, so as to lessen product volume and the costs of the hardware and assembly. This kind of PCB complies with RoHS requirements and the SMT process. It produces fewer wastes to the world.

Third, ordinary glass fiber PCB has poor heat dissipation performance, while ceramic PCB is relatively stable and it is not easy to deform under high temperature and humidity environment, but the price is relatively expensive, and it is often used in high-end products. The aluminum based PCB mixes both advantages of the glass fiber PCB and ceramic PCB. The aluminum based PCB is cheap, meanwhile, it can dissipate high temperatures effectively.

During operation, the surface of the power device is mounted on the circuit layer, and the heat generated during the operation of the device is quickly transmitted to the metal base through the insulation layer, and then the metal base transfers the heat out, so as to realize the heat dissipation of the device. Aluminum substrate insulation layer is the largest thermal conductivity barrier in the power module structure. The better the heat conduction performance of the insulation layer is, the more conducive to the diffusion of heat generated during the operation of the device, and the more conducive to reducing the operating temperature of the device, so as to improve the power load of the module, reduce the volume, prolong the life, improve the power output and other purposes.
