Title:
MULTILAYER CERAMIC CAPACITOR AND PRODUCTION THEREOF
Document Type and Number:
Japanese Patent JPH0696986
Kind Code:
A
Abstract:

PURPOSE: To protect the ceramic part of a multilayer ceramic capacitor against crack when the external electrodes, fixed to the opposite ends of the multilayer ceramic capacitor, are soldered to a board conductor.

CONSTITUTION: Content of glass frit in a silver baked terminal 3, conducting with an internal electrode 2 of a multilayer ceramic capacitor, is set at 5-15wt.% with respect to silver. End face of the silver baked terminal is then subjected to mechanical grinding, e.g. sand blasting, or corrosion with acid thus removing the surface layer by several μm thick and exposing a silver face which is then subjected to nickel plating of several μm thick. Furthermore, an external electrode is formed at a part of the silver baked terminal 3 where a solder plating layer 5 is formed on a nickel plating layer 4.
