Superior No. 312 Photovoltaic Ribbon Assembly (PVA)
Superior No. 312-PVA No-Clean flux is specifically formulated for use in Photovoltaic Ribbon Assembly (PVA) in which tabs are soldered to cell contacts. No. 312-PVA can be manually applied directly to the interconnecting ribbon, or it can be applied automatically via a tabber and stringer soldering system through either dip or spray mechanism.
We offer Superior No. 312-PVA in three different sizes. Sizes available for purchase are 1 gallon bottles, 5 gallon jerrycans, and in 55 gallon drums. For custom sizes or a quote, Contact Us.

Superior No. 312-PVA With its low solids content (around 2%) and unique activator package, as well as it being both halide- and rosin-free, Superior No. 312-PVA leaves virtually no residue on the cell post soldering. Cells are left dry and cosmetically clean as they exit the tabber and stringer machine. In addition, a unique anti-corrosion additive keeps the cells clean and corrosion-free for the duration. Superior No. 312-PVA performs under a wide solder temperature range and can be used in conjunction with both leaded and lead-free alloys.
