QA MODELING
Are Current Qualification Practices Adequate?
It is well known that devices and systems pass existing QT only to fail in the field. Other devices undergo extensive – and expensive – testing. Is this a problem? And do we truly understand the cost not just of failure, but of excessive test? A new approach to qualifying electronics devices could ensure a predictable, and low, probability of failure.
