Title:
CHIP-TYPE CERAMIC ELECTRONIC COMPONENT AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2022/065004
Kind Code:
A1
Abstract:
Provided is a method for manufacturing a chip-type ceramic electronic component that has an external electrode structure which can protect a ceramic element body from cracks due to stress caused by flexure of a substrate and the like, and can have a lower electric resistance than a resin electrode. An external electrode 11 includes a glass-free sintered layer 12 that does not contain glass. A glass-free conductive paste, which contains a thermosetting resin, and conductive metal powder formed of an alloy of tin and at least one selected from among copper and nickel, but does not contain glass, is prepared, the glass-free conductive paste is applied to cover a portion of the surface of a ceramic element body 3, and then the ceramic element body 3 coated with the glass-free conductive paste is heat-treated at a temperature, which is 400 °C higher than the curing temperature of the thermosetting resin, for example at 600 °C. Most of the thermosetting resin is thermally decomposed or burned away by the heat treatment, and the conductive metal powder is sintered to form an integrated metal sintered body 13.
