Title:
METHOD FOR PREPARING GREEN-BODY CHIP OF THREE-TERMINAL MULTI-LAYER CERAMIC CAPACITIVE FILTER
Document Type and Number:
WIPO Patent Application WO/2024/088387
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing a green-body chip of a three-terminal multi-layer ceramic capacitive filter. The method comprises: providing a printing plate and cast ceramic thin films, wherein the printing plate comprises tab-containing electrode patterns and penetrating electrode patterns, the tab-containing electrode patterns and the penetrating electrode patterns are arranged at intervals in columns, avoiding portions are provided at the positions, which correspond to tabs of tab-containing electrodes, of the two sides of penetrating electrodes, and supporting patterns are provided at the two ends of the tab-containing electrodes; placing the printing plate on the cast ceramic thin film to perform electrode printing; according to a certain number of staggered positions, stacking ceramic thin films which have been subjected to electrode printing, and performing lamination after stacking, so as to obtain bars; and cutting the bars to obtain the green-body chip of a three-terminal multi-layer ceramic capacitive filter. The method for preparing a green-body chip of a three-terminal multi-layer ceramic capacitive filter in the present invention has the advantages of reducing sawteeth, burrs and connections between electrodes, ameliorating the defects of a bread form during high-capacitance lamination, bending of a sintered electrode, etc., and reducing the failure probability of short circuiting of a chip, etc.
