Alpha® EcoSol

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.

Alpha EcoSol Bar and Reel Features:

  • Low Cost – Over 30% below the price of most other Pb-Free alloys
  • Low Melt Point relative to other popular Pb-free alloys
  • Exhibits Mechanical Reliability, Soldering and Electrical Conductivity performance deemed acceptable to PV Module Assemblers and Industry Standards (IEC-61215 and 61730)


Benefits:

  • Low price supports transitioning to Pb-free without incurring substantially higher solder costs
  • Has a liquidus temperature near Sn60Pb40 solder and above conventional lamination temperatures. This, combined with excellent wetting characteristics, means ALPHA EcoSol can generally be “dropped in” to most current cSi module assembly processes with no change in throughput.
  • High mechanical strength ensures long module service life
  • High conductivity means no module power loss after transitioning to ALPHA EcoSol
