MG Chemicals8341-10ML 8341 No Clean Flux Paste, 10 milliliters Pneumatic Dispenser (Complete with Plunger & Dispensing Tip)

This stuff is pricey compared to other generic flux, but its worth it. It performs MUCH better than the flux paste I previously used. It seems to reduce the viscosity and allows the solder to flow much better/faster than before. Also, the syringe applicator is significantly easier to work with than the toothpicks I used to use. Happy with the purchase.

1. The No Clean Flux Paste is an essential tool for professionals engaged in the touch-up and repair of surface mount assemblies. Packaged in a convenient syringe dispenser, it allows for precise application, ensuring efficiency and accuracy in repairs.2. Formulated with a unique blend of high-grade synthetic resin and thixotropic agents, this flux paste is specifically designed for use with both high-temperature lead-free and conventional Sn/Pb alloys. It delivers optimal fluxing activity, promoting rapid wetting action and extensive wetting spread.3. As a no clean formulation, the residues left behind do not require removal for most applications, making it an ideal choice for streamlined processes. Its excellent wettability, non-conductive, and non-tacky residues ensure compatibility with both lead-free and leaded solder systems, enhancing overall performance in electronic assembly tasks.

I love this for easily adding a touch of flux.As others have said the back part, plunger, tends to fall out. No big deal, but you can add a small rubber band or o-ring near the inner end and it will stay in place. Experiment.Also, if you are in a cool room and the flux is hard to push out, heat the tip with something like a soldering iron, heat gun, or even your fingers.

This is the second MG syringe I buy. When my first ran out I decided to try a different flux (quick chip) and instantly regretted it. I returned the other flux and bought this item again. I will continue to use this flux until I can no longer find it. It works extremely well even at low temperatures and cleans up easily compared to other fluxes I've used. The only time I have issues cleaning is when I use way too much heat and burn it.My primary use is SMD rework with 60/40 and 63/37 MG chemicals solder.

Like others have mentioned, this flux takes way too much effort to get it out of the tube. It also continues to flow once you break the skin on your thumb pressing so hard and then set it down which gets a bit messy and is somewhat wasteful.The plunger does stay attached unlike the chipquik brand.Once it is applied, solder flows really well and the residue is easy to clean up.Overall, it worked well. The force required was a drag but then again, the chipquik plunger that falls out bothered me too. I am going to try the Kester brand next which is about twice the cost but...

Very good flux

It is what it is—a flux paste. It works and does exactly what you need when the time comes. No complaints!

I've been using a flux pen and other types of rosin flux for a while and none have given me the results that this product has given me. The cheapest of solder wicks will work great with some of this smothered on it before application. I just swapped out every single capacitor on a Vectrex gaming system and this along with a lot of wick Made the job so much easier. Highly recommended.
