Abstract:

The primary areas of process improvement studies were 1 binder control 2 anodizing and reforming 3 pyrolytic conversion 4 carbon and silver coating and 5 materials control. In addition, capacitors were examined for parametric stability after 1000 and 2000 hours of life test. After 2000 hours of life test the average value of capacitance and dissipation factor remained unchanged, within the error of measurement, for sample sizes from Lots 1939-B and 1939-D the average value of d-c leakage increased 23 percent for Lot 1939-B, and it decreased a factor of 16 for Lot 1939-D. Based upon the 2000 hour life test performance the best electrical characteristics have been obtained with Lot 1939-D. Author
