Aluminum substrate as a special kind of PCB, its application field has long been all over the communication, power, power, LED lighting and other industries, especially high-power electronic equipment will almost use aluminum substrate, and aluminum substrate is so popular, are due to its following characteristics:
Excellent heat dissipation performance: As we all know, heat dissipation is particularly important for high-power electronic equipment, and the biggest feature of aluminum substrate is its excellent heat dissipation performance, compared with other metals and alloys, aluminum has a higher thermal conductivity and lower heat capacity, which makes aluminum substrate can more effectively conduct and disperse the heat generated by electronic components. Thus improve the reliability, stability and service life of the equipment.
Strong machinability: aluminum is relatively soft compared with other metal materials, so its plasticity is strong, and it can be processed into various shapes, so as to apply to a variety of different PCB design needs.
Excellent corrosion resistance: Aluminum exposed to the atmosphere, it is easy to form an oxide film on the surface, this layer of oxide film can provide some protection for the aluminum substrate, so the aluminum substrate itself has a certain corrosion resistance, of course, this layer of oxide film in response to high alkaline or acidic environment is too sufficient, so, in order to enhance the corrosion resistance of the aluminum substrate, In the production process, some surface treatment processes are usually taken to further provide the corrosion resistance of the aluminum substrate, and the aluminum substrate after surface treatment can work stably in some special environments.
