3pcs No Clean Soldering Pen Rosin Solder Pen for Electronics Tabbing Wiring Solder, Welding Maintenance of PCB Board, Liquid Solder Pen, Solder Braid Wick Liquid Solder Flux.

Makes a huge difference trying to solder without any flux. My joints were clean and strong. These pens are very easy to use on something like FPV stack.

no mess and accurate , good for hobbyist

Easy to use pens the flux allows the solder to run well. Very good value but instructions are not in English

Does the job

I got these as a no clean flux pen seems to be a good idea for small work to be done on PCB boards, I used these pen for working on a TF socket I wanted to remove as it was broken and needed some flux to go o a really small area of solderI wanted to remove. The pens may be ideal for your purpose, one of the pens was partially on the dry side (did not try the other two pens as I finished what I was working on). Useful on small jobs, can't tell how much flux is left inside as you cannot see through the pen. Recomended.

All 3 seem to work, a few repairs yielded success so far.

Not ideal pens had leaked a fair bit in the packaging. I found the tip size to be relatively clunky for smaller elctronics. The flux seemed to do a decent job when I managed to get some on the board. I would not waste my money on this product again. Much better options available.

je suis decu de cette achat la quantite de liquide sortant de ces stylos est mediocre vz ne pouvez pas les utiliser facilement sur des pieces hors circuit pas assez de liquide sortant du feutre du stylo.je vais commender l'autre version celle qui foncionne avec seiringe
