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

I bought 10ML of MG Chemicals - 8341 on 4-2020 and I forgot I had it for over 5 years! Well I popped the top and to my surprise it was absolutely perfect. I quickly noticed it was really thick and moderately difficult to push out of the large nozzle. I was testing my new Sequre ht 140 hot tweezers. With the assistance of this flux it worked like a dream. When heated the thick opaque cream turned sticky and runny. Spanning out away from the heat source. As I heated the pad on the board and feed the Kester to the tip the flux did it's magic and a beautiful mound of solder formed on the board pad. Not much smoke at 350C and no smell was detected. Being 5 plus years in storage it worked perfectly. I felt that satisfaction well up inside me as I moved to the next pad. The only let down was cleaning the flux off of the board. I was as sticky as a glue trap for mice. ISP had to be applied and scrubbed 4 times to remove it. Aside from that, the flux functioned perfectly and was easy to use. 5 star product as I see it.

This stuff is amazing if you get it in the "pneumatic dispenser" I just call it a syringe. The stuff in the tube is not that easy to work with, and not a good refill for the dispenser if you have an empty one; it has some included solids that block up the applicator tube. I like that I can dispense a very small amount, and with the cap it lasts for years. I have bought 3 of these in the last year because I don't do that much soldering, but each time it's because I ran out, not that the flux went bad.

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.

Pricey, but definitely awesome flux!

Order the stuff to do motherboard on a cluster on a Chevy vehicle. It worked well and helped easy to use. It came sealed. The value was pretty good compared to the others

This flux makes you feel like a pro when soldering. Very easy to work with too!

Easy and works

I never knew how much I needed this until I saw it. I always tried to use the solder suckers and always ran into issues. One use with this stuff and I'm sold for life. Just heats up the entire area and gives you that freedom to move the solder around or pick it up rather than having to risk burning some stuff up (I'm not a very skilled solderer but I try, and this stuff makes me feel a little more skilled). Will definitely be buying a few packs of this just to keep stocked up and avoid any painful desoldering days. The setup is easy. Everything connects together simple. Instructions make it very easy. Application onto the surface is controlled and not just shooting out like crazy glue in a tube. I really feel more in control of my projects with this stuff than I ever have before. It's like finally having that stuff I saw in tutorials that made it all look so easy. Best thing ever for my soldering confidence. Buy it if you need it.
