    Has all test data been reviewed for trends, oddities, “out-of-family” values, and other indicators of anomalies?

    Suggestions, Observations and Lessons Learned

    Where possible, test sets should collect quantitative data (rather than Pass/Fail) and enable automatic trending

    Excessive current draw during electrical test (suggestive of an impending short) and high G spikes (indicating intermittent rubbing) during acoustic or vibration testing should be carefully reviewed.

    Many problems occur during the first temperature cycle. Therefore, the results after the first cycle should be scrutinized carefully.
