摘要
MLCC是经过多层材料堆叠共烧后制成的,在其制作过程中,产生分层是比较严重的质量缺陷之一,严重影响MLCC在使用过程中的可靠性。对MLCC产生分层的原因进行分析归类,总结出MLCC产生分层的原因为:制作MLCC内浆与瓷粉TMA(热机械分析)曲线匹配性不佳;MLCC在烧结前存在排胶不良;烧结回火温度或氧含量高。
MLCC consists of multi layers of dielectric and metal electrodes sintering together.delamination is one of the main quality defects during the manufacturing,which has a significant effect on the reliability during the application.Classify the reasons of delamination,and find failure reasons are non-matching between ceramic dielectric and inner electrode paste,not well of binder burn out before sintering;high reoxidation temperature or high oxygen content during the sintering.
