Abstract
The effect of the mixing procedure of dielectric materials on electrical Properties for multilayer ceramic capacitors(MLCCs) with Ni-electrode has been studied. When mixing is not enough, the fraction defective of insulation resistance is high and the failure mode of accelerated life of insulation resistance show two types (early failure mode and wear-out failure mode). As a result of analysis, segregated phase of small amount of ingredients was detected at the defective spot. These segregated phases resulted from lack in mixing of dielectric materials. It is concluded that highly reliable MLCCs with Ni-electrode are achieved by controlling the mixing procedure of dielectric materials.
