MG Chemicals 8342 RA Rosin Flux Paste, Amber, 50 g Jar (8342-50G)

Great product

I love this stuff for desoldering through hole components. The synthetic and no clean fluxes on the market just aren’t penetrative enough when mixing unleaded with leaded for through hole desoldering work. This is the only stuff I trust that won’t have me overheating the PCB. Synthetic stuff is great for surface mount but you just can’t beat real Rosin flux for through hole! It does have the downside of having to clean it much more thoroughly but it’s worth it to not be battling different heat settings for different types of solder.

Once I opened the container, the smell told me all I need to know. Perfect quality! I was going to give up on my soldering Iron tip as I couldn't clean the oxidized at all. Tried different method, unsuccessful. This paste cleand it in a matter of seconds. Although it's not good for soldering tips, but sometimes I have to use it. Just keep in mind to keep your soldering iron tip covered with tin to prevent it from corrosion.

The flux works really, REALLY well - as expected of MG Chemicals, but the way the syringe is put together is kind of annoying, since the plunger part keeps falling out.

Packaged well and works as advertised. Glad to have it in my soldering arsenal.

Works great no problem at this time a must have

Definitely does what I needed, it performs great 👍 clean up afterwards with the highest content of ipa % you can get and Bob's your uncle! The smell reminds me of the rosin that used to come in the Deoxit jars.

Used for soldering and desoldering. I have a couple of MG Chemical flux "pens" that work MUCH better, but they don't last very long, so I figured I'd order the syringe and get some more mileage out of it. It doesn't work *nearly* as well as the pens did. It's a little better than 'bargain bin' flux syringes, but I was expecting this stuff to blow my doors off, and TBH it didn't. You might as well either buy the pens or buy the cheap stuff because this isn't markedly better than the cheap stuff, and it is noticeably worse than the pens.
