PRODUCTION ENGINEERING MEASURE FOR THE IMPROVED RELIABILITY OF CAPACITORS, FIXED, SOLID ELECTROLYTE, TANTALUM HIGH-RELIABILITY 10MFD-20 VOLT CAPACITORS.
Abstract
Work was performed in six areas of process improvement studies, and includes the initiation of a pre-Pilot Line Test Run; the areas are: (1) binder control; (2) pressing and sintering; (3) pressed density control; (4) pyrolytic conversion; (5) carbon and silver coating studies; and (6) X-ray analysis and encapsulation. The major results obtained were: (1) the variation in the average CV per gram for the several experimental pressing and sintering runs, using the BR-150 binder and binder ratio, was within five percent; (2) the average CV per gram for the pre-Pilot Line Test Run was fifteen percent lower than that obtained on the experimental runs, again using the BR-150 binder and binder ratio, but a different powder lot was used which had a different particle size distribution than that used for the experimental runs; (3) pressed density control data showed that the pressed densities obtained with the BR-150 binder were well within the control limits for both the Mean and the Range Control Charts; and (4) capacitors fabricated with the carbon curing temperature twenty percent greater than the control curing temperature had, comparatively, a significantly lower average dissipation but not a significantly different average d-c leakage.
