The performance test of silver paste includes resistivity, adhesion, fracture, hardness and other aspects after silver paste printing. Most of them are done by printing the pattern of silver paste on the film, drying and sintering it to solidify it, and using an ohmmeter to test the resistance performance of the silver paste and the degree of deviation of the ratio of resistance and line width.
