Your cart is empty. Syringe-type rosin solder paste, made of no-clean, halogen-free, acid-free, non-corrosive, and residue-free, helps to make the soldering firm. This electronic solder flux has a medium viscosity and can automatically inject tin into the soldering position.
The role of rosin solder flux in soldering: support heat transfer, remove oxides, reduce the surface tension of the soldered material, remove oil stains on the surface of the soldered material, increase the soldering area and prevent re-oxidation.
No-clean, halogen-free, acid-free, non-corrosive, moderate viscosity, no residue
Flux paste product applications: suitable for sensors, wires, motors, fuses, connectors, metal housings, lighting, electronic components, SMT repair, BGA chip implants, etc.

This is a nice little kid of flux for any soldering project. It works just as you'd expect, helping clean services and getting the solder to flow smoothly. I like the included tips that allow for way more precise application. The flux has been very easy to use and pretty effective. I recommend it!

So when a certain computer manufacturer (whose name sounds like Snapple) decided to become more "eco-friendly", they made their motherboards with lead-free solder. Sounds great until you suddenly see your entire screen go into pink and white circus lines--graphics board failure from cracked solder joints!And oven re-balling only lasts for a short time--not good either. The only solution is to remove all the old solder and re-ball the board using solder with a little bit of lead in the mix--lasts forever. But this product is the way to get everything prepped for the job the right way! It removes the oxidization layer that so often screws up a soldering job--and makes the new solder joint flow like butter on a hot piece of toast.Highly recommended!

I do a lot of soldering. My projects include restoration of vintage radios, including ham radio transceivers. Many times I’m working with old soldering joints that used lead solder. Those solder joints are particularly hard to remove, they are more like cement than solder. I saw this 4-pack of soldering flux and thought it would be a great value for the price based on how much flux was included and the additional fine needle attachments that I often need. I have used many different brands of solder flux - form the top expensive brands to the inexpensive and you never quite know what you are going to receive until you put it through the paces. I’m very happy to say that this soldering flux works great. It helped me to remove those stubborn solid solder joints. I also like to use it in a general way to help my regular solder flow even better when laying down long lines and areas of solder. This is really good flux - it cleans up easily and well, it’s easy to use with the included needles, and having a full 4-pack at this price is incredible. Definitely a recommend from me to any electronics enthusiasts out there.

This flux comes with short and longer application tips. It's a low viscosity flux and dispenses very easily without a tip, so be caution with application. Flux works perfectly fine with solder joints and not much if any residue in work area, but still needs cleaning from what I have experienced. Not much, but does seem like sticky residue afterwards. No problems with redoing solder points applying this flux with new or existing solder. Leaves a nice finish to solder joint.

Great flux workls very well and its kind of thick so easy to place it right where you need it without getting it on other components.

I’ve been doing a lot more surface mount work lately and so I appreciate a flux that I can place with a needle and it’ll stay put. This complete kit comes with 4 syringes and 4 plungers, 4 longer needles and 4 shorter ones. There are plenty of spares in case of accidents. This flux flows well when heated and has really helped me up my precision soldering game. It doesn’t put off excessive fumes and appears to be no-clean but I usually do a little final cleanup with alcohol anyway. It’s a great value for 4 tubes of flux. Highly recommended!

I like the syringe supplied soldering flux and how precise the flux can be applied. Four tubes of flux along with needles for precise application at a great price. This is an easy to use system that is a definite must to any electronics professional or hobbyists bag.

This flux is a little more viscous, and great for working with surface mount electronics.The previous one I was using was a rosin flux, which was more liquid. It came with a squeeze bottle with a thin nozzle. It typically ended up running wider than the specific area of the board I was working on. I think I will use this more fluid one for helping copper braid wick better.This flux does a nice job staying where you apply it, and seems to burn off fairly cleanly. I think since it stays put, it's easier to burn off all the flux while soldering. I don't know if rosin is the only primary ingredient, so make sure to use a fume extractor when working with this stuff.
