I clean up the board when I'm done with 99% IPA, and blow it dry with air. It is tried and true, even if it does leave a sticky mess behind. Personally, I use liquid rosin-type flux. If your board is just popcorn analog or digital stuff with no high voltage, no high impedance, no precision requirements, etc.- then by all means, go ahead and use no-clean flux. I think the no-clean flux actually eats into the solder mask or something. 95 Tinning Flux is NSF-listed for potable water applications. It cleans, tins and fluxes most commonly soldered metals. The worst part is that you can *try* to clean a board that has been soldered with no-clean flux using water or whatever chemicals you might have in your kit, but it is almost impossible to get it all off of the board, and it still causes problems with high voltage and/or impedance circuitry. 95 Tinning Flux is a petrolatum-based flux containing tinning powder to help pre-tin the pipe. This is due to the fact that it leaves a slightly conductive residue behind. There is a slight problem with "no clean" flux though- on very high impedance circuits, or high voltage, the no-clean flux can cause problems. Turnout Control Devices, Signaling, & Detection.Quote from: on December 20, 2014, 01:51:15 am "No-Clean" flux is all "the rage" these days, and if you are having your boards built by an outside assembly contractor, they probably use this by default.Layouts, Design, Planning, & Operations.Photography/Videography (Techniques & Equipment).If you do that and tin the wire ahead of time you can set the wire on the pad and literally "tap" the iron to the top of the wire and you get an instant perfect joint, no need to add solder. Use a pen like the Kester pen to just tap a decoder pad before soldering a wire. Watch your feeder stick the first time, really easily. Use a micro-brush to apply some flux to the rail where you are going to solder a feeder and let it sit for 60-120 seconds to "clean" the area. Watch the solder suck down inside it 10x faster. Use a toothpick to put a small amount of flux inside a rail joiner before you solder it on, then solder. Putting flux in the right place makes a HUGE difference in your soldering. Lastly, I have a Kester pen with "no-clean" in it I use for all of my electronic work (e.g. repairing a feeder, or soldering a replacement segment of rail) where the best cleanup I can do is a swab with a damp paper towel. Regular acid-based "electronics" grade flux, generally used on in-place track work (e.g. fastrax fixtures) if you can clean the part afterwards. I keep three fluxes around, plumbing flux bought at home depot this is good for some track work or other heavy soldering (e.g. "No clean" fluxes have no acids in them and thus need no cleaning when you are done. Generally acid based fluxes should be washed in a water bath after soldering which is not practical on in-place track work, or electronic boards. what you use on plumbing pipes) may have some acid left behind that slowly eats the metal over time. Generally the heat of soldering consumes all of the flux, but not always. It can clean the area to be soldered, and solder is attracted to flux when you do the actual soldering. You’ll notice the difference right away if you use flux before you apply the rosin core solder, not only will it be faster, but you won’t have as much heat dissipated through your piece.įlux serves two purposes. This where dipping the tip and wiping it on a damp sponge comes in. Well that’s because the tip is dirty and there isn’t enough flux in the solder to clean it. Have you ever noticed when the solder just doesn’t want to go on the soldering iron tip and you know it’s hot. ![]() ![]() I’ve seen the flux inside the solder leak out in hot weather so how do you know if there is enough. I’d rather just let the flux do the cleaning so use additional flux before. If you’re soldering something that takes a lot of heat, the flux inside the solder will burn off before it gets a chance to clean the surface. Even if you thoroughly clean everything with a file or sandpaper it still isn’t enough and how do you clean inside a joiner. Rosin core solder isn’t always enough especially in track work when there are a lot of machine oils. ![]() What's that do? Does it help the solder to flow even better than it already does?Dipping helps clean the tip of the soldering iron fast. Somebody above mentioned that they dip the tip of their soldering iron into it. Now that I think about it, I've always used rosin core solder without really wondering why. My initial question was, "What does rosin flux do / what's it for?" BUT, then I went and did a little homework and found out the answer. Get the best deals for rosin soldering flux at.
