Liquid Solder Flux Dropper (30 ml/1 Oz.) I RMA Liquid Solder Flux I Soldering Flux I Electrical Solder I No Clean Liquid Flux I Rosin Flux I Soldering Flux for Electronics I Lead Free Liquid Solder I

This flux is some of the best flux I have ever had for the money definitely get this product is very versatile it works on all boards and components bleeding into boards as extremely easy to use you do not waste very much at the bottle is easy to grip and it fits in your hand so very well squeezing it and not too much comes out which is perfect it has great control on the nozzle I would say that this is a very superb product and anybody that works on electronics and does soldering needs this product

This flux worked great for soldering lugs and helped the solder bond well. The needle applicator is convenient, and the thin rosin flows nicely, making it easy to apply. While it requires a bit more cleaning than clear no-clean flux, it performs exceptionally well. Getting back into electronics after a long break, I've found this to be much better than the paste flux I used before. The bottle makes application easy, and you don't need much. This is a great addition to any electronics bench, and highly recommended for its affordability and effectiveness.

No smoke, Clean, good results, the only thing bad it’s a little bit sticky but with alcohol 95% problem solve

They definitely mean **liquid** when they say “liquid flux.” That’s on me—I was hoping for something with a consistency somewhere between paste and liquid, but their description is accurate. As a flux, it does exactly what it’s supposed to do and helps the solder flow nicely. Because it’s a true liquid, it also flows *everywhere*. This can be helpful, but sometimes problematic. When soldering through-hole components, for example, it drips straight through and coats the underside of the component, which isn’t always ideal. For those situations, I’m finding I still prefer traditional paste flux. Cleanup is typical, maybe a bit stickier than what I’m used to. You’ll definitely want IPA on hand to clean it properly. One small note: The package didn't come with instructions on how to install the finer-point nozzle. However, if you scroll through the product photos on Amazon, you can see how it’s done. Once I figured that out, installation was easy and the fine tip works really well for getting flux into tight areas. Overall, it’s not a bad flux at all—just make sure you know what you’re getting and whether a fully liquid flux fits your workflow.

It's thin, and it's runny, and if that's what you need then this is what you want! It works well both with leaded, and lead free solder. A bit messy but it does the job!

Great item. Worked good. Good quality!

This liquid flux is fantastic! The dropper never clogs and works wonderfully well; it drops just the right amount that you want onto your board. The flux itself is very effective and makes soldering SMD parts with a regular iron so much easier. Cleanup is quick and easy with alcohol.

I’m not a big fan of using flux. Most times you can avoid using it, but there is the occasion where you need to use just a teeny tiny a bit of liquid solder flux, just to get things going. If you watch the YouTubes you may see several video creators that do retro computer restoration or what have you, just swathing that gunk all over the place by the half gallon at a time! Don’t believe it people! Melt a little new solder onto an old blob if it’s being stubborn, and you never have to use flux. Again, except for in certain circumstances. I do computer and video game console PCB repair, recaps, etc. I also work with solid state pinball machines by the plenty. There are times when components are just too close together or just stubborn going through a ground plane that you just gotta add a little flux. That’s why this teeny tiny bottle comes in handy. It’s got two types of applicator tip, one is molded into the model and the other is a screw on metal needle, which is super tight! Especially if you’re tighten it! My first use with this bottle was on a Bally pinball MPU board from the late 1970s. That suffered from battery leakage. Which means removing a whole bunch of components, cleaning the alkaline damage, repairing the alkaline damage, and then reinstalling new components that were damaged. This was actually the first time I used liquid solder flux on a board. Typically, I go without, as mentioned earlier, or use solder flux paste. This is much easier, and you don’t have to crank up the heat output on your solder iron nearly as much to get things free. My choice heat range is about 625°F, but with liquid flux, I could go slower, at about 550°F. These are my observations, your results may vary! Ask for value for money, it’s a little pricey for how little you get, but at the same time, I’m not going to be using this whole bottle in a day or in a week or maybe even a year, so the price isn’t too terribly bad in the long run. The quality is good, it’s not incredibly slimy like the flux paste, and much easier to clean off after being worked with. Yes, I would recommend this! It’s kind of the tool that you don’t use too often, but it sure is nice to have around!

Really good stuff, cleans the metal well for soft soldering. East to fit parts. good value for money, not particularly sticky, but runs well into joints, Would recommend.

Huge fan of this flux, because it is easy to apply where you want it and very effective in improving flow and adhesion. I get really clean joints that flow so easily with this flux. It says it's "no clean," and I think that's a bit of a stretch, but it does clean up pretty easily, especially compared to other fluxes I've used. Also, it lasts a long time. I've used it on every joint (and there have been a lot of joints) for a couple of months now, and I'm maybe 1/6 of the way through the bottle. Plus, it's a Guatemalan company, which I appreciate. It's nice to actually have global goods in a global market, and not just all the goods coming from the same city in the same country (no shade, Shenzhen).

Excellent product for clean soldering, worth the cost

Probablemente un buen producto pero llegó en mal estado, la tapa no estaba bien cerrada y había una fuga en el embalaje. Espero novelas…

It's a nice product
