DC-DC converter, which is widely used in system and equipment, is a kind of complex component. The technology maturity of the device seriously influences the reliability of the system and equipment. AHP combined with KPA was proposed to evaluate the technology maturity for DC-DC converter. The failure modes and failure mechanisms of the device were studied. The CTEs belonging to the different dimensions...
Failure analysis is a vital tool used in the development of new products and for the improvement of existing products. And electromagnetic relay is indispensable and widely used in automatic electrical system, which has complex special structure and every component might fail. The failure analysis for electromagnetic relay have a series of methods applying for a number of failure models. The different...
Water vapor is one of the most important contaminants which caused devices failure. Internal water vapor content of hermetic package devices is closely related to the sealing performance, water absorption substances inside the package, leak plugging and other factors. The main mechanisms of leak plugging and water absorption by moisture absorbing substances are theoretically analyzed in this paper...
