The aim is to show how to calculate a suitable heatsink for a semiconductor device and the precautions needed for handling, mounting and soldering techniques.
Thermal resistance characterizes the assembly's resistance to heatflow generated by the junction during operation, which depends on the materials between the junction and ambient air.
