thermal management precautions for handling and mounting
Introduction
The behavior of a semiconductor device depends on the temperature of its silicon chip. This
is why electrical parameters are given at a specified temperature.
To sustain the performance of a component and to avoid failure, the temperature has to be
limited by managing the heat transfer between the chip and the ambient atmosphere. The
aim of this note is to show how to calculate a suitable heatsink for a semiconductor device
and the precautions needed for handling, mounting and soldering techniques.
