![]() This flux is active, cleaning off the oxides and residues from the soldering nozzle, but since it does not contain Chlorides, it leaves a cleaner residue than fluxes that do contain Chlorides. 515 is based on a Hydrobromic Acid activation system. Place the envelope on the bottom plate and then press your weed by closing the plates (consult your rosin press instructions) Leave the disk between the plates at 220F for 60-90 seconds. I have cleaned the board as best I can with isopropyl alcohol, which gets rid of the tackiness of the rosin, and also. Place your micron bag containing your weed disc at the back of the envelope. 515 is a soldering nozzle conditioning flux that contains no Chlorides. I have a nice looking purple PCB from Laen's batch service, which I have assembled using rosin flux. 23 does not contain any Ammonium Chloride, a chemical that may be regulated in certain countries. 75, is a conditioning flux formulated for tinning soldering nozzles. 75 contains Zinc Chloride and Ammonium Chloride. When not regularly tinned, there is an increased likelihood that the solder will begin to flow unevenly, leading to inconsistent or ineffective soldering of the PCB. Regular and proper tinning of the top and side of the solder nozzle barrel ensures the solder will flow evenly and consistently out of the nozzle. 75 is a conditioning flux specifically formulated for tinning the soldering nozzle on selective soldering machines. (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 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. Superior SSF-RMA20 is a Type RMA rosin flux formulated for selective soldering applications. SSF-WS80 is classified as an ORM0 per J-STD-004. 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 equipment. Superior SSF-WS80 water-soluble flux is a neutral, alcohol-based flux ideally formulated for selective soldering applications. SSF-NC400 is classified as an ROL1 per J-STD-004. This No-Clean flux’s activity level is robust to meet the rapid activity, leaving a bright solder finish and no visible residue. Superior SSF-NC400 is an alcohol-based, No-Clean flux that contains a specialized rosin/resin blend that 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. SSF-NC50 leaves a clear residue and is effective for both lead-free and lead-bearing solder alloys. SSF-NC50 is also formulated to withstand the higher temperature requirements of selective soldering applications. The information may be insufficient or incomplete for manufacturing and production purpose.Superior SSF-NC50 is a VOC-free, No-Clean flux that promotes the rapid activity necessary for selective soldering. Liquid Rosin Flux 1 (Flammable, health hazard)ĭisclaimer: The information provided in this page are for information purpose only. Silver Brazing Flux, Paste, Inorganic, Water washable Liquid/paste Flux, water soluble (Flammable, Irritant, health hazard) Avoid prolonged or repeated contact with skin. Liquid Flux, Inorganic, Water washable 2 (Irritant, health hazard) Liquid Flux 2 (Flammable, Irritant, health hazard) Warning: Keep away from heat, sparks and flame. ![]() ![]() Liquid Flux 1 (Flammable, Irritant, health hazard) Please read the MSDS of all materials before handling them. Many formulas contain flammable or corrosive ingredients. All formulations must be made by chemists or individuals with sufficient experience in making chemical compounds. In most cases you will be able to modify the ratio of the ingredients to fine tune a formula for your own application however, if you need help in doing that please call me or email me for assistance. Many liquid flux formulas contain gum rosin however, I am also writing some formulas that do not contain rosin. Liquid flux is crucial for surface mount soldering and many other soldering tasks. Soldering flux helps solder to spread out and “cling” to metal by reducing the surface tension and removing oxides. ![]()
