Failure analysis and construction analysis of electronic and electrical components have been the primary emphases of the Southwest Research Institute (SwRI) Component-Analysis Group since 1978. Using specialized equipment, experienced analysts perform:
Normal wear out of the contact-arm pivot in this snap-action switch diverted some of the load current through the spring in the over-center mechanism. Joule heating raised the temperature of the spring high enough to melt the thermoplastic
actuator, thus allowing the spring to move into a neutral position that disabled the over-center snap action and made the switch inoperative.
Package opening and decapsulation
Mounted cross sectioning
Unmounted cross sectioning
Wire-bond strength measurement
This integrated circuit die failed because of an accidental short circuit during manual probing of the circuit board. Future failures were avoided with more careful probing techniques.
