Electronic flux ISO-Flux ClearWave, 25720071, Felder
The 25720071 is an alcohol-based, colophony- and halogen-free no-clean flux for the mechanical soldering of printed circuit boards with THT or SMD assembly. It exhibits excellent activation properties and has excellent spreading properties on all common soldering surfaces. The low solids content ensures optically residue-free soldering. An extremely low acid value and minimal residue after soldering lead to an extremely high surface resistance value in the SIR test. The flux can be applied to the PCB using any known fluxing method. ClearWave is ideally suited for wave soldering systems with spray fluxers as well as for selective soldering systems, especially with dropjet fluxers, as it prevents the jet nozzles from sticking and the spray mist is not sticky.
