Learning About Flux

I’ve read that flux is a useful thing to use when soldering, but I never really knew what it does or what the real uses were. I was aware that it helps solder stick, and that the usual soldering tin I used contained flux, but I just wasn’t sure exactly what it was or when to use additional Flux. The advice I read most often was when you try to solder an SMD chip, flux is really handy to drag solder pins. However, that just tells me when to use it, but not what it does. However, I saw a simple video that really drove the point home to me. It simply shows examples of soldering with and without flux, and changes some variables around so you can directly see the effect. Now that’s some educational material!
