55℃ to 100℃. The working temperature of silver paste is (℃)-55℃ to 100℃, the volume resistivity (ω/cm) is 0.002ω/cm, the thermal conductivity (w/m k) is 2.5w/m2℃, and the silver content is 60%. Silver paste is a kind of viscous paste made of high purity (99.9%) metallic silver particles, adhesives, solvents and additives. Conductive silver paste has very strict requirements on composition.
