CHIP QUIK NC191 Smooth Flow Tack Flux No-Clean (10cc Syringe)

Man, I love this stuff! I recently used the Chip Quik Flux to repair a circuit board, and it worked flawlessly. The application is super easy, thanks to the included needle tips, which allow for precise placement without any mess. If you’ve ever struggled with applying flux cleanly, this setup makes a huge difference. It flows well, spreads evenly, and makes soldering a breeze. Seriously u gotta try it! What really sold me on this product was the recommendation from a professional repair shop northbridgfx—and now I see why. The flux activates quickly, helping the solder bond smoothly while preventing oxidation. Whether you’re working on tiny SMD components or larger joints, this stuff just gets the job done. It also cleans up easily with isopropyl alcohol, leaving no sticky residue behind. If you’re into electronics repair, this is a must-have in your toolkit. Just be sure to store it properly to prevent it from drying out, and you’re good to go

Works great for everything, even bga soldering. It doesn't get too smokey, doesn't smell horrendous, and doesn't become super hard and sticky when burned/heated. It has a nice viscosity, it isn't runny, nor is it too sticky. Cleaning it up is also super easy with isopropyl alcohol. For a flux this quality and this price, you can't go wrong. Great value. It also comes with two tips, one being thinner to apply a more controlled amount.

Don't know how I was soldering without flux. Badly probably. Inexpensive, flows nice, and easy to apply with the included tips. This flux is extremely helpful, and virtually no cleaning is necessary. The fumes do smell, which is as expected since some types of flux are not safe to inhale so keep your station ventilated and remember to wear your PPE. :)

As ordered good flow easy application works great

This flux works well, it does leave a thick film but some Isopropyl alcohol and it comes off pretty easy, for bigger jobs a little hot air helps to remove it. The biggest issue is with the fumes, it smoke alot when used to remove IC's with hot air, if you happen to breath it in it literally will take your breath away. So make sure you have a good fan or fume extractor going.

This solder flux works well and easy to apply... Only negative is it smokes a little too much for me, thank God for smoke adsorbers...

Apparently, I was pretty ignorant. I'd soldered here and there for two decades (XLR connectors, repairing joints for loose connectors on PCBs, etc.), and always struggled and didn't understand why other people could make a joint in a second and I'd have the hold the iron on for what seemed like minutes and still wouldn't get a good joint. Flux! Flux transfers the heat to both pieces and lets the solder melt and flow basically instantly. I just tinned some wire ends both ways - four seconds or so to get solder to flow into the strands with just a wet iron tip, vs half a second with a tiny dab of flux on the wire. Tinned the pads on some WS1812s again in a fraction of a second and then got passable connection to my wires in another second per joint with no flux, just both sides tinned. I am by no means a pro, but I'm beginning to understand how you get to be one. Flux, my friends! Good flux!

This is absolutely amazing stuff , makes soldering so easy . I love it .

Work as expected. More than enough for all the small soldering jobs I would imagine I ould do.

Brilliant flux, it’s well worth the money to spend a tad more to get quality! It has made my hobbyist soldering a doddle.

it works, no special smell

Used this flux for some simple repairs to a PCB with good results but I was lazy and didn't setup my extractor. It was only a small bench job and I;ve used rosin flux in a similar situation without ill effects. However the fumes from this stuff really got to me and was shocked at how toxic they are, leaving me with a sore throat and burning eyes. Don't cut corners with this stuff, use an extractor every time!

Works really good but the fumes are horrendous. I got them for to have for in-field emergency soldering jobs which they are perfect for, but beware of the noxious-smelling fumes.
