The semi-aqueous halogen-free No-Clean Flux HW139 consisting of a solvent mixture of alcohol and clean, completely demineralised water complies with the current environmental policy developments. The reduction of the VOC content is particularly beneficial if no VOC-free flux can be used due to application conditions.
· Good activity, wetting and wicking
· No visible residues
· High surface insulation resistance
· No obstruction for ICT
The flux HW139 has mainly been developed for application using spray fluxers. Due to the increased preheat temperature in comparison with purely alcohol-based fluxes, the contained water can be evaporated well. The contained activators are also optimally activated here and the preheating of the circuit boards is ensured.
