Failure Analysis in Electronic Components

  • Posted by Manuel Padial Pérez
  • On April 21, 2020
  • 0
Failure analysis is the process of analysing the component data or the component itself to determine the reason(s) for degraded performance or catastrophic failure of a component either, during component manufacturing and testing, during incoming inspection, or after delivery to the customer, at the final application. Since there is an infinite number of variables in play at any one time, it is important as the first step in any failure analysis to understand how and when the failure occurred.
