Generally, the only real issue is with the organic stuff (water washable). Weeks of trying to figure out why the boards didnt work ensued. Solder flux is a chemical cleaning agent that serves three key purposes in soldering: Flux removes oxidated metals and corrosion from the surfaces youre. We went through hell at the day job where the person doing the ordering wasn't exactly the coldest beer in the fridge and she arbitrarily restocked all the rosin based solder with organic based and all our cleaning procedures went out the window (ultrasonic cleaner with IPA doesnt work on organic flux). To add to the OP: Dont use solder that you cant get a data sheet for. The silicone is a natural desiccant so it absorbs moisture to cure The flux residue left after soldering is non-conductive and non-hygroscopic. And solder flux pcb clean, can quickly remove soldering pcb without damaging. The result was a hermetic thin layer of a soft silicone-ish material. It can be applied by foam, dip, spray or brush. Shop soldering rosin flux cleaner online with fast shipping and fast delivery. There are tons of spray on conformal coatings for this, the way we did it was to wash the board with methanol, dry with compressed air, and simply spray on. I'd like to get this sorted out eventually. The tricky bit is that unless I can be completely certain of having removed all of the moisture, I would just be sealing it onto the board instead. Ideally, I would like to seal my boards better against moisture, as I live in a coastal town. If I see that perf or pcbs need cleaning before I solder them, I use acetone. Rosin Flux: This type of rosin flux is not active at all it Is used. If gunk from tap water remain upon the board and non-porous parts, it's because they were sticky and not 100% clean in the first place. Rosin Mildly Activated: You can use this flux to clean plated lands or solder coated leads. As for residual minerals, the way I see it, they are not likely to just deposit themselves onto a clean surface. If they need especial cleaning, I use isopropyl.
I do not even use flux most of the time - just clean parts, a hot tip, and the flux which is in the solder already. Flux-Off is available in aerosol, BrushClean System, and liquid form for vapor degreasers, spray systems, ultrasonics, and dip tank applications. What I have been doing is cleaning them with extremely hot tap water and a brush.
