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 specifically designed for the
photovoltaic industry.
SnPb and Pb-Free Solder Alloys
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.
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 specification.
