INDIUM CORPORATION Indium Wf-7742 Voc-Free Wave Solder Flux

No Price Available

Code WF-7742

VOC-free fluxes use water as the dominant solvent. In addition to limiting the amount of volatile organic compounds (VOC) into the atmosphere, sometimes associated with global warming, VOC-free fluxes are also non-flammable. The disadvantage of VOC-free/water-based fluxes is that they require more pre-heat to drive off the water than similar alcohol-based fluxes. In addition, assemblers must be careful to ensure that the top side of the circuit board is dry, otherwise it could lead to reliability issues in the form of electromigration.

WF-7742 is a VOC-free, no-clean fl ux specifi cally developed for Pb-free wave soldering of surface-mount, mixed-technology and through-hole electronics assemblies.

WF-7742 is a water-based, nonfl ammable formulation dramatically reducing VOC emissions and eliminating special storage requirements. A wide process window provides excellent solderability on diffi cult to solder assemblies and reduces solder balling.
