Solar cell assembly materials

The 979T VOC-free no-clean flux, 951 alcohol-based no-clean flux , and 950E alcohol-based no-clean flux targeting tab attachment in solar module assembly.

The 979T VOC-free no-clean flux is a low-residue flux targeting high-reliability applications. It is solvent-free and designed for tab attachment.

The minimal residues left after soldering are benign and non-conductive. The 951 alcohol-based no-clean flux is designed to solder various metallizations easily. The residues are non-tacky, minimal, and non-conductive.

The third flux in the solar industry product line is 950E alcohol-based no-clean flux. It also targets multiple metallizations and has non-tacky, minimal, and non-conductive residues.

Flux content is available in 2% and 3% concentrations within the company’s solder wire for solar applications. There are 275 high-reliability no-clean flux wires available in leaded and lead-free alloys.
