-
- You have probably never soldered *without* flux. The rosin core in
- ordinary electronic solder is the flux.
-
- The purpose of flux is to clean the metal that you're about to solder to.
- The idea is that the flux melts and gives the metal a quick cleaning,
- flowing just ahead of the solder.
-
- BUT I hope that when you used a separate flux, you used a kind that is
- suitable for electronic work! The kinds used in plumbing (zinc chloride,
- etc.) are not reliable, over the long term, in electronic gear. They
- have a nasty habit of continuing to corrode over the years. This wouldn't
- be a problem in plumbing, where the soldered joint is _big_, but in
- electronics, a millimeter of crud isn't tolerable.
