摘要
多层陶瓷电容(MLCC)是目前广泛使用的无源器件之一,其失效将会严重影响到机载计算机产品的可靠性,从内在因素、环境因素、电应力情况分析讨论了影响MLCC可靠性、造成MLCC失效的各种原因,提出了应对的预防措施,并在机载计算机产品上进行了相应的实践应用,从而剔除不良品,预防使用中MLCC的失效,提高产品可靠性。
The MLCCis among the abroad use of parts of an apparatus, It＇s make a full impact on aircraft computer reliability, Failed reasons of MLCCcan be divided into a lot of kinds： intrinsiCfactor, external environment, foul weather, eleetriCstress, and main overcoming ways are discussed, The application of new ways to aircraft computer, eliminate the false and retain the true, new ways precluded MLCCfrom invalidation and increases reliability.
