Production Engineering Measure for Improved Reliability of Subminiature Metallized Polycarbonate Capacitors.
Abstract
The objective of the work program for process improvement and testing of production lots of metallized polycarbonate film hermetically sealed capacitors was to establish a failure rate under static test conditions with a goal of .001% per 1000 hours. In particular, effort was concentrated in the process improvement phase in these areas: (a) Quality of metallized polycarbonate film; (b) Heat Treatment of capacitor sections; (c) Shrinkage of film; (d) Solvent entrapment within the film; (e) Burn-in of the completed capacitor. Information pertinent to the process factors evaluated and results obtained in each area is detailed and the engineering decisions incorporated into the pre-production and production lots are delineated.
