Superior Flux offers a full range of Flux Pens. The flux pens featured on this page are our three most popular. More fluxes are available in flux pen form upon request. We are happy to work with you on Flux Pen private label projects. In addition to Flux Pens we sell additional fluxes for hand soldering of PCBs including our No. 135 Rosin Paste Flux and our No-Clean Tacky Flux and Water-Soluble Tacky Fluxes.
Superior No. 312 No-Clean Flux Pen is the ideal No-Clean flux pen for PCB hand soldering, rework and repair applications. The flux has a low (2%) solids content, thus leaving a clean residue that has the added benefit of being water washable if one chooses to clean the board after soldering.
Superior No. 80 Water Soluble Flux Pen is a neutral pH halide-activated flux. Its high activity level makes it suitable for difficult-to-solder surfaces, and it is compatible with all non-water-soluble solder masks. No. 80 Flux Pen is water soluble; the post washing solder joint is shiny without worries about post-solder corrosion.
Superior No. 99-20 Rosin Flux Pen offers all of the advantages of a rosin flux in an easy-to-use flux pen format. Though No. 99-20 is classified as a Type RMA flux (per specification Mil-F-14256C), it has also been third-party verified as a No-Clean flux per J-STD-004.
