Abstract : Continued difficulty has been encountered in producing the 750 1.0 mfd polycarbonate capacitor pilot run. Two lots of approximately 800 polycarbonate capacitors each were produced. Both lots had poor yields due to shorting at the clear ing operation. A large number of those capacitors which survived the clearing operation had poor IR's and poor Q's. Failure analysis has revealed a number of possible causes and remedial actions are being taken to improve quality and yields. The exact cause or causes for poor yields has not been fully determined as yet and effort continues in this direction. (Author)
