Abstract

The invention discloses a silver paste suitable for ceramic filter spraying, which comprises the following components in terms of mass percentage: 75-82% of silver powder, 0.2-3% of glass powder, 0.5-1% of aging adhesion promoter, Resin 8-14%, organic solvent 7-15%, auxiliary agent 1-3%; the resin is a hydroxyacrylic resin, the molecular weight of the hydroxyacrylic resin is 1000-5000, and the viscosity is 1000-4000mPa.S. The invention also discloses a preparation method and a film-forming method of the silver paste suitable for spraying on the surface of the ceramic filter. The silver paste of the invention enhances the storage stability, can adapt to the metallization of the surface of the ceramic filter with complex structure and special shape, improves the strength of the silver paste dry film, and improves the adhesion between the silver film and the ceramic surface of the filter. The preparation process and spraying process of the silver paste of the present invention are simple, the silver film after sintering is firm, not easy to fall off, uniform in thickness, and can be adapted to mass production of ceramic filters.

Description

technical field

[0001] The invention relates to the technical field of silver paste, in particular to a silver paste suitable for spraying a ceramic filter and a preparation and film-forming method thereof. Background technique

[0002] With the great development of 5G infrastructure industry, the key component of 5G base station - 5G ceramic dielectric filter will also usher in a big explosion. Metallizing the surface of the ceramic filter with silver paste is a connecting link in the whole process of the ceramic filter, which determines whether the ceramic filter has the possibility of mass production.

[0003] At present, the metallization process used in ceramic filters is mostly screen printing silver paste, but the screen printing process is only suitable for metallization of filters with flat surfaces, because the filter surface needs to be fully metallized, even for bulk devices. Printing on the 6 sides separately, drying 6 times, the production efficiency is low, a...
