When the heatsink standard demand is high, we should choose aluminum heat sink or skiving heat sink, which is because the aluminum heat sink in the process of extrusion forming. Heat transfer rate is very fast, heat attenuation is very small, but many aluminum heatsinks may not fit users’ electronics space planning, sowe may need to selecting refer to the instruction and then  process and manufacture.

When standard demand is not that specific. We can choose bonded fin heat sink or soldering heat sink. These electronic heatsinks can work out the shape size and craft according to customer's CAD drawings, which can be called custom heat sink.
