Description
This water-based flux was specially developed for solar technology, especially for soldering solar modules, tabber and stringer material as well as for connecting cells. EO-S-023 is a No Clean flux, VOC-free, halide-free, resin/rosine-free formulation and optimised for use in wave, selective and hand soldering processes.
EO-S-023 is powerfully activated and leaves no sticky residues. The activators are specially designed for the higher temperatures required in the manufacture of solar modules without compromising their effectiveness. The application can be carried out using all standard application methods (except foaming). The solids content is 2 %. EO-S-023 is completely free of corrosive effects.
Customer added value
Non-flammable (no legal restrictions on transport, storage and handling)
Very good soldering properties (wetting)
Available as a concentrate in granulate form
Wide process window (high thermal stability, good activity over a long interval)
Very good residue behaviour (optically very clean, high SIR)
