摘要
为了解决多层片式陶瓷电容器(MLCC)在高可靠产品应用、研发验证和产品改进等环节对快速可靠性评价技术的需求,提出了一种基于Procopowicz-Vaskas模型(P-V模型)的高加速寿命试验(HALT)评价方法,开展了某10μF 6.3 V MLCC产品在9组不同高温、高电压下的HALT研究。获得了样品在不同温度和电压应力下的失效分布特征,其P-V寿命模型参数的激活能为1.30 eV、电场加速因子为3.79。建立了高容量MLCC产品的HALT寿命模型,为其可靠性快速评价提供了参考。
In order to satisfy the need for rapid reliability evaluation technology for MLCC in high reliability product applications,R&D verification,and product improvement,a HALT evaluation method based on P-V model is proposed,and the HALT of a 10μF/6.3 V/0805 MLCC product under 9 groups of different high temperature and high voltage is carried out.The failure distribution characteristics of the sample under different temperature and voltage stresses are obtained.The activation energy of P-V lifetime model parameters is 1.30 eV and the electric field acceleration factor is 3.79.A HALT life model for high-capacity MLCC products is developed,which can provide a reference for rapid evaluation of their reliability.
