Abstract

The invention discloses a silver paste, and the silver paste is characterized in that the silver paste contains the following components by weight: 10 parts of silver powder, 2-4 parts of varnish, 3-10 parts of diluent and 1-15 parts of fluxing agent, wherein the purity of silver powder is 99.99%, and the particle size is 1-10 micrometers. The application technology comprises the steps: carrying out the transferring or coating of silver paste on a carrier, and carrying out sintering under the temperature from 510 DEG C to 980 DEG C to form a film, wherein the sintered film has a conductive function and a decoration function. The silver paste is very high in beauty after sintering, is high in conductivity, and can meet the special conduction demands. The sintered film is more beautiful after polishing.
