WF-7745 is a water-based, VOC-free, halogen-free, no-clean wave solder fl ux designed for wave soldering through-hole, bottom-side surface mount and mixed-technology circuit boards. It performs well with both Pb-free and Sn/Pb solders and processes.
WF-7745 is non-fl ammable, dramatically reducing volatile organic compound emissions and eliminating special fl ammable storage conditions. WF-7745 easily passes the IPC TM-650 copper mirror test. It also passes the IPC TM-650 copper corrosion test, showing no evidence of green. This high degree of corrosion resistance is virtually unheard of with water-based no-clean fl uxes.
Even with this high degree of corrosion resistance, WF-7745 solders as well as many halogen-containing, low solids, no-clean fl uxes, yielding superior hole-fi ll and reduced solder balling.
Features
- No green from corrosion test, commonly found with other VOC-free fl uxes
- Compatible with Pb-free and Sn/Pb solders
