| Silver paste with different substrates, the glass powder with different composition is needed. The material system Bi2O3-SiO2-B2O3 is used to study the effect Ag2O on the adhesion of Zn2SiO4 dielectric ceramics. When the content (mass fraction) of Bi2O3 is 65%, SiO2 is 15%, B2O3 is 10%, Ag2O is 5%, and Al2O3 is 5%, the prepared silver paste adhesion is larger than≥20N. All the indexes of the silver paste, such as printing performance, square resistance, adhesion, wettability and solder resistance, can meet the requirements index. |
