Im looking for flux to use when soldering circuit boards will this work?

If you are looking for flux to use for soldering circuit boards, you need to consider looking elsewhere. Will it "work", sure, but it may damage the board you're working on. This kind of flux is acid based, it's meant for pipe fitting, not for electronics. The same goes for stained glass, the acids won't damage it. It says so in its description "ideal for use with 95/5 and other common solders." In electronics soldering, leaded solder is preferred. It flows a lot easier, and a long as you don't eat it you won't be poisoned.

Is this an acid flux? thank you.

I Believe do. I got it to solder a glass piece but haven’t used it yet

Will this work with harris sta-brite solder (96% tin/4% silver, melts at 430 f)?

I use this with a Wen 250 watt soldering gun , and it works Great with Light gage solder [ I use it for rewiring chores all the Time ]
