导致MLCC失效的常见微观机理
Microcosmic mechanism of causing failure of MLCC
【摘要】 多层陶瓷电容器(MLCC)在实际使用过程中,电参数会发生不同程度的偏离,降低了可靠性,直到MLCC失效。其失效原因可分为外部因素和内在因素,分析讨论了影响MLCC可靠性的内在因素——MLCC内部分层、导电粒子、金属离子迁移和介电老化等常见微观失效机理,并提出了主要应对措施。
【Abstract】 In practical application of MLCC,its electric parameter will change and reliability will degrade until it fails.Failed reasons of MLCC can be divided into two kinds: internal and external.The former are inner layer,migration of conduct particle and metal ions,dielectric ageing and so on.And main overcoming ways are discussed.
