SRA Solder No-Clean Electronics Soldering Flux Paste, Safe for Lead and Lead Free Assembly. Non Acid Flux for Soldering Electronic Circuit Boards (PCBs) and Electrical Wire Tinning. USA Made (2oz Jar)

Not too much to say, it's Flux paste. However, it's very easy to use and apply, and clean up afterwards. Works great!

After reading some of the reviews about how hard this is to apply, I was a little hesitant. It works well. On a day to day basis, I'd rather use rosin based liquid solder, but a paste is so much easier to carry around. This paste is a bit stiff which makes it kind of hard to work with - it's about as stiff as Chapstick brand lip balm, but it's not terribly bad. In fact, I melted some of it down and filled an empty lip balm tube to carry this around in my portable electronics repair kit. Works like a charm.

I used to use normal rosin flux for soldering but this no clean flux is much better. Not having to worry about cleaning up your PCB after soldering is very convenient. I can a little bit of flux on all of the parts I'm going to soldering using a toothpick and I've had great results.

Works good to help solder ps4 hdmi

I prefer mg chemicals flux but bought this to try. Overall it’s not a bad flux but not something I’d personally buy again as I rarely use it. No complaints really cause it is decent quality

Great flux. My first time using this brand and had no issues. Appreciate that it is no clean. I wouldn't hesitate to use it.

This product is awesome. Works really well.

No smoke coming up. No crazy/toxic smell. I can do SMD, especially TQFP and SOIC footprints easily. TSSOP/SSOP is still a bit hard for me. Just amazing product. There are so many fake products out there from China that are toxic. I am so happy to have found this product!
