Abstract
A process for isolating flaw sites in the dielectric of solid electrolytic capacitor comprising immersing a conductive polymer impregnated capacitor in an electrolyte solution, and then alternately subjecting the conductive polymer impregnated capacitor to a high voltage and a low voltage; wherein the high voltage is between about 10 volts and 50 volts, and the low voltage is between about 0 volts and the voltage corresponding to 90% of the anodization voltage for pellets anodized at less than 20 volts, or the voltage at which the current drops to 50% of the peak voltage current for pellets anodized at voltages greater than or equal to 20 volts. The period of time at or above the anodization voltage is relatively short to prevent damaging the dielectric film.
