CHIP QUIK NC191 Smooth Flow Tack Flux No-Clean (30cc Syringe)

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.

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

I like this better than others I have tried. Works well and the dispenser is convenient

I got this because I wanted to fix up some electronics that needed SMD components replaced, I had never done SMD soldering before and was very surprised at how easy this flux made getting decent solder joints while working with smaller leads. Frankly it was like magic with how well it works and I couldn't find myself ever soldering without flux again. The price was good and you get a decent amount, quality product.

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.

If you think your bad at soldering this is why. You were not using good flux. This stuff made me have bad soldering joints, not fully sucking up solder with solder sucker. Solder wick not working. It fixed all of those issues. Also solder stays liquid for a second longer than not using the solder. This is great when cleaning but holding an say SMD ceramic capacitor to a board you have to wait around 2-3 seconds before it hardens. So if you bump what you are doing it will slide even if your iron is not touching. I used wick and cleaned pads to be bare copper, when before I could not do this or lifted a pad because heating it too long. YOU HAVE TO HAVE THIS STUFF ITS LIFE CHANGING! Also buy one of those silicon tip solder suckers, AMAZING.

I am a hobbiest for the most part. I enjoy getting under the microscope and trying to fix smd boards. Flux is a must. I always make sure to buy enough of this flux so I don't run out. I've tried many others. Some are better than others but this is my favorite. NC191, whatever is in it, behaves just how I'm looking for flux to behave. It does give off smoke fumes that you don't want to breathe so make sure to use some sort of ventilation.

it works, no special smell

I’m always looking to buy Amtech, but can never find any in Canada. And it’s available in the US but I’m not willing to spend $50 with shipping on a little tube so this is apparently the next best thing and I found this by mistake too I started micros soldering with this, just because it was available and I have tried other brands in between, and I always end up with this one on my desk. It works for reballing the middle board and bga chips. With quick 861dw and hakko fm203. Just make sure to get a good smoke extractor.

Very useful
