Analysis of the Factors Influencing the Insulation Resistance in Preparation of Microwave MLCC

在即定原材料和多层电容器整体结构设计基础上,立足于微波片式多层陶瓷电容器的规模化生产工艺,对各种影响绝缘电阻的生产工艺因素进行了系统研究。结果表明,工艺因素对微波片式多层陶瓷电容器(MLCC)绝缘电阻的影响较大;在实际生产过程中,优化流延工艺改善陶瓷膜片性能,在印刷中采用合适的内电极烘干温度,叠层后采用合适的干燥工艺、合理的排胶烧结制度和电镀工艺均能有效提高微波MLCC的绝缘电阻。

Based on the determinate raw materials and the whole structure design, the factors influencing the in- sulation resistance in the preparation of microwave multilayer ceramic capacitors （MLCC） were investigated. The results showed that the parameters in the process technique have very important effect on the performances of ML- CC, and the insulation resistance of the MLCC could be improved effectively through optimizing the tape casting process, drying the tape casting and electrode at appropriate temperature, and optimizing the process of hinder re- moval, sintering and plating.
