摘要：結構分析（CA：construction analysis ）是一種通過對元器件的結構進行一系列深入細致的分析來確定元器件的結構是否存在潛在的失效機制的方法。通過CA可以評估制造商的設計能力和工藝水平，也可以確認元器件的結構是否能夠滿足特定的應用環(huán)境要求。CA對應用于高可靠領域內(nèi)的元器件的質(zhì)量保證尤為重要。
Abstract:Construction analysis (CA) is a method to determine if the construction of device have the latent failure mechanism through a series of analysis. CA can evaluate the capability of design and the level of workmanship. In the other way CA can determine if the construction of device can meet the requirement of the particular usage environment. CA is very important for the device using in high relibility applications.
