Which is the best performance and the cheapest cooling solutions?
To answer this question we have to discuss this issue.
There were many PCB types know by decades’ experience PCB designers.
Like ENIG PCB, HASL PCB, immersion tin PCB, MCPCB etc.
Aluminum base PCB is the most commonly used among them.
The material of aluminium base PCB
If you have read our before articles about the MCPCB board.
You may know some of the material.
Anyway, we want to all guys know the correct the material of aluminium base PCB.
The metal core of the thermal PCB can be aluminum, copper (copper clad PCB) or mixture of special alloys.
Advantages of Three layer aluminium base PCB
Aluminium base PCBs are composed by a unique 3-layer structure includes copper (conductor layer), dielectric Layer and metal substrates.
Its metal base heat dissipation plate is a low-alloyed Al-Mg-Si-based high plasticity alloy plate, which has a good thermal conductivity, electrical insulation performance and mechanical processing properties.
This enables aluminium base PCB outpace conventional FR-4 in the capability of loading currency with the same spec.
