Abstract: The purpose of the secondary screening is to eliminate the early failure products with potential defects through non-destructive screening test and to guarantee the reliability of the whole machine.In order to achieve a good screening effect,effective screening items and methods are very important.Capacitor and discrete components may easily introduce defects or cause failure in the process of secondary screening due to improper operation.The quality control of capacitor and discrete components in secondary screening process is particularly important.The article highlights the two typical tests during the secondary screening to give detailed explanation of the quality control for secondary screening.

Key words: secondary screening, electrostatic protection, test, electrical aging
