Sn96.5Ag3.5

Features:  


Eutectic lead-free solder, melting point 221℃

- Good mechanical properties

Conductivity is better than Sn63Pb37

- Good creep and fatigue resistance

- High reliability of welded joints

- Compatible with all types of flux





Describe:


The melting point of Sn96.5Ag3.5 solder is 221℃, which is higher than that of traditional tin-lead eutectic solder, and its wetting performance on Cu substrate is also slightly worse than that of tin-lead, but its tensile strength, shear strength, fatigue strength and creep resistance. The change properties are better than Sn63Pb37 solder, the mechanical properties and oxidation resistance are superior to Sn-0.7Cu. Sn96.5Ag3.5 has been used in the electronics industry for many years as an alternative to tin-lead solder. The Sn-Ag binary solder with Ag mass fraction of 3.5%~5% has been successfully applied to hybrid circuits, and Sn96.5Ag3.5 has been used in reflow soldering.
