Title:
METHOD FOR MANUFACTURING HIGH-CONDUCTIVITY WIRE, ALLOY AND NEW-SHAPED TERMINAL ELECTRODE
Document Type and Number:
WIPO Patent Application WO/2022/246589
Kind Code:
A1
Abstract:
A method for manufacturing a high-conductivity wire, an alloy and a new-shaped terminal electrode, which improves the conductivity of a thick-film aluminum electrode, such that the conductivity thereof is equal to or close to that of a thick-film printed silver electrode or a copper electrode, which is sintered in a reducing atmosphere, and manufacturing the terminal electrode of a new-shaped laminated ceramic assembly comprises replacing the thick-film aluminum electrode with a high-conductivity thick-film metal or alloy electrode by means of chemical oxidation-reduction replacement; and coating a thin film on the surface of metal aluminum particles by means of a chemical or physical process to form a core-shell structure, sintering and heating same to generate a film-coated metal and aluminum alloy, and then liquefying the alloy to connect same with the closest packed aluminum particles to obtain a thick-film printed aluminum electrode with ultra-high conductivity. By being applied to the terminal electrodes of laminated ceramic assemblies, pentagonal terminal electrodes, which are dipped and sintered at a high temperature, are changed into low-temperature two-three-sided terminal electrodes, which are printed and made by wet electroplating or chemical plating.
