Selective Soldering Fluxes
Superior SSF-NC50 is a VOC-free, No-Clean selective soldering flux. This No-Clean flux promotes the rapid activity necessary for selective soldering. SSF-NC50 is also formulated to withstand the higher temperature requirements of selective soldering applications. SSF-NC50 leaves a clear residue and is effective for both lead-free and lead-bearing solder alloys. SSF-NC50 is classified as an ORL0 per J-STD-004.
Superior SSF-NC400 is an alcohol-based, No-Clean flux designed specifically for selective soldering. SSF-NC400 contains a specialized rosin/resin blend that leaves a clear residue and is effective for both lead-free and lead-bearing solder alloys. This No-Clean flux’s activity level is robust to meet the rapid activity required in selective soldering, leaving a bright solder finish and no visible residue. SSF-NC400 is classified as an ROL1 per J-STD-004.
Superior SSF-WS80 water-soluble, selective soldering flux is a neutral, alcohol-based flux ideally formulated for selective soldering applications. SSF-WS80 provides the activity of a water-soluble flux, but as it is neutral, it should not corrode the stainless steel components of the selective soldering apparatus. SSF-WS80 is classified as an ORM0 per J-STD-004.
Superior SSF-RMA20 is a Type RMA rosin flux formulated for selective soldering applications. SSF-RMA20 has the controlled activity of an RMA flux, but contains the ideal amount of solvents to reduce the clogging of the flux sprayer nozzle typical with rosin-based fluxes. (Note: The clogging of flux spray nozzles with rosin residue can often by cleared up by flushing the flux spray apparatus with Isopropyl Alcohol 99%.) This rosin flux conforms to Mil-F-14256, Type RMA, and ROM1 per J-STD-004
