835-PX2 Flux Pen Soldering, 2 x 10 mL, Amber

This was one of my best experiences using flux at home. My other syringe of MG Chemicals flux worked well with soldering but was a slow messy process to get out of the syringe. With these pens it is SOO much easier. These are no clean but it still leaves a flux trace after soldering. This residue does dry firm so it is not a goopy mess like previous fluxes which is also a huge plus.

After reading several reviews here on amazon, I was a little hesitant to purchase these pens. I did not experience any of the issues others have complained about while using them. When I first opened the pen, I was careful to only press down enough to prime the pen. The tip will turn yellow when it is saturated with the flux. Once the tip is primed you really do not need to pump it or press hard for the flux to flow. I used this to modify the motherboard inside an original xbox console and the solder points were very small. This pen put just enough flux to board to allow a good solder connection without drenching the board in flux. It worked exactly like it needed to. I would recommend this product to anyone, just use it as intended.

I love rosin flux in pen form. I used to use it all the time for assembling really small surface mount components and this product hit the nail on the head m as to what I was wanting for all applications! Doesn't gel up, cleans up great with isopropyl alcohol and a Q-tip or what not. Shipped quickly and works great!!

Purchased these before. The felt tips wear out quickly if not careful to avoid rough areas or component stems. This last set leaked during shipping, making them un usable.

I bought the 2x pack of flux pens. The first one was extremely difficult to press down and ended up breaking and just leaking flux everywhere. BUT amazon refunded me half of this order. The second pen was very easy to press down and saturate the tip. Probably just a fluke on the first one. If that happens to you, maybe saturate the wick in ethanol or IPA and then press down again, don't force too hard.

Recently got into some small electronics repair. And I knew I needed to pick up some flux. Saw these on a YouTube video I was watching and thought it looked like a nice easy convenient package for when I was doing. Only used it once or twice so far but very impressed thus far

Of the flux pens I currently have, it's the one I'm most certain will work without problem. When I use this to apply flux to the surface and pins, I solder pretty quick. Like nearly every flux pen you have to be careful running it over the pins as the tip will fray, but I've seen other that do worse.

It's flux in a pen. Not a lot of room to mess up.

Great for novice solderers! It enables the user to replace chips without bridging! Great product

I will buy this again.

I have used some no clean flux pens and I find when heated the fumes are really bad. This flux is not. Leaves residue but not conductive and easily cleaned off. Dispenses nicely from the fiber tip.

Nice for sparingly applying on old solder joints for desoldering

worked well once it got flowing. flux formulation is decent.
