Abstract

A method of screening a lot of capacitors is provided. The method includes measuring a first leakage current of each individual capacitor in a first set of capacitors and calculating a first mean leakage current; removing each of the individual capacitors having a measured first leakage current equal to or above a first predetermined value, forming a second set of capacitors; subjecting the second set of capacitors to a burn in treatment; measuring a second leakage current for each of the individual capacitors in the second set and calculating a second mean leakage current; comparing the second leakage current for each of the individual capacitors to the first leakage current for each of the individual capacitors; and removing each of the individual capacitors having a second leakage current equal to or above a second predetermined value and/or having a second leakage current that does not change by a specified amount compared to the first leakage current for each of the individual capacitors.
