Abstract :
This article discusses the estimated failure rate of electronic components when these are exposed to harsh environment involving vibration, dust, humidity, high temperatures, and others. So, it presents a compilation of the resulting physical-chemical effects upon stressed electronic components, and how such effects can reduce the component life. Also presented here is a compilation of the results of an ample and thorough research of different standards of reliability prediction, making it a critical and comparative analysis between the different techniques, methodologies and applications of each standard studied. Furthermore, for the reader to have a broader understanding of the methodology used in standards, an example is presented of a typical SV-PWM converter used in motor drive systems under different environmental aspects, in order to compare the methods under study.
