The importance of the various available fluxes used in soldering
- Now let's talk about flux and what it is and what it does. Flux is a chemical based on rosin that helps reduce the amount of corrosion when heating up the metal of the solder and making that electrical and mechanical connection. The solder is like a pipe and inside of it is a small amount of flux. So while you solder, the flux actually melts and keeps that connection clean of oxidation and help with the wetting. So why would you need flux? That's a good question. And typically you don't. If you need to rework something and you need to add more flux, sometimes you can just add a little more solder and you're actually adding more flux from the solder. But if you do a lot of soldering, at some point, you're going to say, "Wow, I really wish I had something "just to clean that joint up "so that I could go in and rework it, "fix a mistake, change a component." And that's where flux comes in handy. My favorite way of…
