SRA Solder 135 Rosin Paste Soldering Flux For Electronics, No Clean Flux Made for Lead and Lead-Free Solder Circuit Boards and Copper Electrical Wire - Safe Clean Residues with No Goopy Mess (2oz Jar)

Seems to do what it's made for.

Great product.. I like that.

My flux came inside the container and not stuck to the lid, for what that's worth! Im using a toothpick to coat my wires with the flux (consistency reminds me of bee's wax). I have also used my 2nd hands metal base, plopped a chunk of the flux there and used my heat gun to melt to dip wires. As a hobbyist these two cans will last me a while!

I generally just use flux paste when de-soldering, this paste works well and cleans up easily.

This was the first flux I ever bought and it made a world of difference. I tried to make my own liquid flux and a real paste to put in a syringe with 91% and 95% ipa. It didn’t work very well at all. I got a tiny amount of liquid flux but a paste is pretty much impossible to make with this drug and ipa. I found it hard to use the proper amount of flux and put it where I want it so I’m more of a paste in a syringe guy but this stuff is still useful. It’ll last you a long time

Fast delivery, quality products

Only 6 or 8 $ but worth it in gold !!!High quality staff here.Yes . Buy it !!!

Often solder will come with a rosin flux core, which is usually fine for basic soldering things together. But for trickier projects having a bin of this stuff is a must. For years I've been plagued with desoldering woes "Why wont this wick work", "why isn't the factory solder melting", "do I really need to run my iron at 410°C to melt lead-free?", etc... No longer. This flux is thick and waxy cold but melts instantly, doesn't evaporate, and can tolerate a lot of heat before burning. It's easy to apply, just use a brush, toothpick, or dip the leads of your component into it. By stripping away oxidation it allows solder to easily adhere to other metals improving your thermal transfer and the resulting joint. If you've ever tried soldering but it won't stick to your wire, it's because you need some of this stuff.I will say, if you let it burn it can be a bit of a hassle to clean up. Isopropanol dissolves it, but once burned you're going to need to scrub. Not that it really matters, leaving the residue of rosin flux isn't really harmful because it's not very corrosive.
