PRODUCTION ENGINEERING MEASURE FOR THE IMPROVED RELIABILITY OF CAPACITORS, FIXED, SOLID ELECTROLYTE, TANTALUM HIGH-RELIABILITY 100 MFD-20 VOLT CAPACITORS.
Abstract
Process improvement studies were conducted primarily on the 100 MFD - 20 Volt capacitor; some of these studies were applied to the 6.8 - 35 volt rating. The areas of process improvement studies were: (1) tantalum powder control; (2) binder and binder ratio; (3) anodizing and reforming; (4) carbon and silver coating; and (5) ageing. Evaluations of combinations of these process improvement studies were made through a series of matrix tests which included temperature cycling, 40-hour burn-in, temperature stability, surge voltage tests, surge voltage tests followed by short term life-tests (40 hours), and life-tests. A reliability prediction is given in which the basis for confidence in attaining the objective of a failure rate of 0.001 percent per thousand hours at a 60 percent confidence level is given.
