ALPHA® SOLDERING MATERIALS FOR PV RIBBON MANUFACTURING

Alpha, the worlds largest manufacturer of soldering materials for electronic applications, produces a host of high-performance materials specifi cally designed for the photovoltaic industry.

SnPb and Pb-Free Solder Alloys

All Alpha alloys are manufactured using our proprietary Vaculoy® process which minimizes drossing of the alloy during the coating process. Several alloys are also engineered to minimize copper erosion.

Alpha’s Pot-Rite® Solder Pot Testing Services help keep your solder composition within specifi cation.

Alcohol and Water Based Liquid Soldering Fluxes

ALPHA® Fluxes are designed to promote rapid surface preparation of the copper ribbon during high speed production while leaving minimal post coating residues.

PV RIBBON SOLDER ALLOY TECHNOLOGY

Alpha manufactures many other alloys depending on customer needs.Alloys available in a variety of forms: ingots, bars, chunks, wire, etc.
