First in the line up is i-SAC 387 Solder, with the addition of Cobalt. The melting characteristic of silver containing alloys has been improved with the addition of Cobalt to offer an optimized lead-free solder solution. Cobalt produces shiny solder joints with a fine grain microstructure, in comparison to standard SnAg3.8Cu0.7. It also has the addition of Germanium, which plays the role of antioxidant, preferentially reacting with oxygen to protect the solder from the oxidation that results in the formation of dross. i-SAC387 has a melting point of 217°C and a specific gravity of 7.5 g/cm3. The second in the new series is Tin Silver based i-SAC105. Also added with Cobalt and Germanium, i-SAC105 has a melting point of 217°C to 227°C and a specific gravity of 7.4 g/cm3. Balver Zinn’s Solder i-SAC105, with silver composition on request between 0.5 to 1.5%, offers a combination of the advantages of silver free alloys and the characteristics of silver containing alloys – as for example SnAg3.0Cu0.5.
