摘　　要：为了得到高可靠性、高抗弯曲性能的多层片式陶瓷电容器(MLCC),采用银、环氧树脂、聚乙烯醇缩丁醛树脂以及无水乙醇等原材料制备柔性端电极浆料。研究了固化工艺和表面处理技术对柔性端电极MLCC的电性能和可靠性的影响。结果表明:柔性端电极浆料在250℃温度以上固化至少30 min,保证了树脂层良好的连接性及可镀性;电镀前采用抽真空和填充技术进行预处理,保证了柔性端电极MLCC的耐热冲击性能和抗弯曲能力。In order to obtain multilayer ceramic capacitors （MLCC） with high reliability and bending resistance,flexible terminal electrode paste was prepared by adopting silver, epoxy resin, polyvinyl butyral resin and anhydrousethanol as raw materials. The effects of curing process and surface treatment on electrical properties and reliability ofMLCC with flexible terminal electrode were studied. The results show that good connectivity and platability of the resinlayer can be ensured by curing flexible terminal electrode paste above 250 ℃ for at least 30 min. Adopting vacuumingand filling technology for pretreatment before electroplating ensure high thermal shock resistance and bending resistanceof MLCC with flexible terminal electrode.
