Liquid Solder Flux Dropper 30 ml 1 Oz I RMA Liquid Solder Flux I Soldering Flux I Electrical

This flux worked great, needed to solder some lugs onto some 0 gauge ofc power cable for audio system and this flux worked great to help the solder bond, applicator is nice, no more worrying about finding a clean brush, bottle is leak proof Read more

This rosin is very thin and flows nicely allowing you to flood your work area. I run my iron hot (600c) and it doesn't burn up or leave any residue that can't be easily cleaned up with IPA. I like the vial better than syringes, in my opinion it's easier to manage and you get more rosin for your money. What I like about this flux is that it cleans up really nice. The attached photo is a PCB after I soldered some programming headers, de-soldered them, and cleaned up the pads with IPA. There's no trace of the rosin flux. Read more

Worked as advertised, it make my soldering easier Read more

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. Read more

In terms of soldering, this stuff did its job, the issue I had was my fault due to my own inexperience. If you're a newbie to soldering like I was and are trying to Solder something like Controller Thumbsticks, this stuff is going to get really sticky and sappy. What you want is the "clear no-clean flux" type for controllers and stuff. It cleans better. This stuff is basically like setting syrupy sap on fire on your circuit board, and the more isopropyl you use to clean it off, the more it gets everywhere, never really getting clean. Also, if you're dealing with Thumbsticks/buttons like I was, keep in mind that the stuff is sticky and hardens when cooled off, meaning that the isopropyl has a chance of washing/guiding the flux you're cleaning off INTO the button/thumbstick, HARDENING, rendering your button inoperable. This is fine, you just need to keep flushing out the button with isopropyl and compressed air until you finally flush that sticky flux out preventing the button from working. I noticed my L3/R3 buttons stopped working after a Thumbstick replacement job, just had to keep putting isopropyl drops and blowing out with compressed air can until it finally got flux out. Flux is a necessary evil, you absolutely HAVE to use it when soldering/desoldering, this stuff is just a lot harder to clean than the clear no-clean type flux. Do some research, so if your job actually needs this type, because I wouldn't use it personally if I didn't have to. It works well, the cleaning is just a lot harder. Read more

Good viscosity and workability for my projects. Wish the cap would go over the needle tip but minor inconvenience. Read more

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! Read more

Solder flux works as expected but it’s a very nasty stuff. It’s leaves sticky surface all over the place and it’s very hard to get rid of. This is the only reason I am giving 3 star otherwise not bad Read more
