Flux HW 139

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.

Product Advantages

  • Good activity, wetting and wicking
  • No visible residues
  • High surface insulation resistance
  • No obstruction for ICT

Application

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.
