Conductive paste and its usage

摘要

Thin, smooth conductive layers for internal electrodes of multilayer ceramic capacitors are produced by a method including the steps of forming a conductive paste layer on a green ceramic sheet with a conductive paste by screen printing so as to have a center-line mean roughness of not more than 1.0 mu m, a ten-point mean roughness of not more than 5.0 mu m and a thickness of metal in the dried conductive paste layer of 0.5 to 2.0 mu m. The conductive paste consists essentially of 50 to 70% of an organic vehicle and 30 to 50% of a metal powder with a particle size range of 0.1 to 1.5 mu m and a mean particle size of 0.3 to 1.0 mu m.
