Aluminum Pcb Heat Sink

- Apr 09, 2018 -

As far as the material of the heat sink is concerned, the thermal conductivity of each material is different, and the heat conductivity is ranked from high to low, namely silver, copper, aluminum, and steel. However, if using silver as a heat sink would be too expensive, the best solution is to use copper. Although aluminum is much cheaper, it is clear that the thermal conductivity is not as good as copper (about only about 50% of copper).
