导电相含量对高银导电银浆微观形貌和性能的影响
Effect of conductive phase content on microstructure and properties of high Ag conductive silver paste
摘要
Abstract
In order to prepare the conductive silver paste required for PET film,a high proportion of conductive silver paste with different contents of conductive phase silver powder was prepared,and the silver paste was printed onto PET film by screen printing.Metallographic microscope,scanning electron microscope,DC low resistance tester,advanced rotational rheometer and ACE-QFH type 100-grid knife were used to test the viscosity,conductivity,bending ability,metallographic analysis and adhesion test of conductive silver paste.In the case of a ratio of silver powder A to B being 5∶1,when the conductive phase content is 65％,the viscosity of silver paste reaches a minimum value of 41.2 Pa·s,the minimum value of the volume resistivity reaches 5.56×10-5Ω·cm,the contact between the point and the surface is also relatively dense,the edge of the printed silver wire is smooth and burr-free,the surface roughness is low,and the adhesion is the best.关键词
