Abstract:

The purpose of this program was to study, investigate and develop non-destructive techniques for the reliability screening of metallized mylar capacitors that are potential failures, from a lot of high quality production parts. This was an 18-month effort and comprised of three phases 1 Investigation and application of certain complex measurements of quality, based on dispersion 2 A study of clearing and burn-in tests under various temperature and voltage conditions, and their effect on capacitance dissipation factors and insulation resistance and 3 A proof test in which the optimum conditions selected from the Phase II evaluations were further evaluated and compared to a control group. The predominant failure mode was identified as low insulation resistance. The most effective test was an insulation measurement condition in conjunction with a burn-in. The most efficient test was the standard dissipation factor measurement condition for eliminating potential failures. Author
