From the world’s leading manufacturer of electronic grade solder materials comes ALPHA EcoSol, the industry’s first Low Melt Point, Pb-free Solder Alloy designed specifically for PV Ribbon Tinning and cSi Module Assembly. ALPHA EcoSol is also low cost, priced well below conventional Pb-free solders, closer to the price of standard Sn60Pb40 solder. The low melt point means it has a liquidus temperature near Sn60Pb40 and above conventional lamination temperatures. It can generally be “dropped in” to most current assembly processes. ALPHA EcoSol has mechanical, electrical and thermal conductivity properties considered acceptable to PV Module Assemblers and passes IEC-61215 and 61730 reliability requirements.
