Life character analysis methods of storage electronic components

Lots of military equipments are in storage, and the equipments are need to evaluate whether showing degenerate character or not, or whether meeting the requirements to use continually or not. Electric components are basic elements, and it is important to evaluate the life character in storage. In this article, the typical components, tantalum capacitor, electromagnetic relays and resistor included, are analyzed with the way of external visual inspection, key electric meters test, inner visual inspection and 3 analysis cases show that external and inner visual inspection can find life characters of electric components, degeneration of key electric meter can be analyzed by key electric meter test. It can be analyzed effectively for life character of electric components in storage with those analysis ways.
