Heat Soak Test in Electronics

The Heat Soak Test is a test conducted for Electronic Components to see if they are able to perform at elevated temperatures.  The theory behind the test is that  chemical reactions can be accelerated at high temperature.  The failure of electronic components such as transistors, diodes, capacitors, etc occur when the chemical properties of the materials change at high temperature.

The Heat Soak Test helps ensure that the components are chemically stable at high temperature and that they have been sized properly.  

The soak test gives and idea of the components stability over a prolonged period of time.

The soak time can vary from a few hours to a few weeks.
