So, I recently re-capped a few problem capacitors on an old LCD monitor. I had bought all the capacitors to re-cap the whole board, just to be safe, but stuck with the problem capacitors because of a soldering issue.
So, when I go to solder, I'll wash the tip on a wet sponge, and it's all nice and shiny. Then after I tin the tip briefly with some solder, the whole outer surface of the iron will turn a brownish/yellowish/blackish color as if its burning something in the air or oxidizing something. Then, those brownish flecks ended up making it into two of my solder joints. They didn't end up hurting the joint, but they didn't look nearly as pretty as the other 4 joints I made.
Is there a way to avoid getting that brownish crap? Is it just a matter of soldering quickly after cleaning the tip? If its' just a speed thing, then I totally understand why i messed that up.
Just so you know, I was using the CHIP-QUIK kit to de-solder the caps. I sucked most of the solder away with a de-solder pump, and then used de-soldering braid to get the solder that was left. I cleaned the joint with an IPA pad, and then soldered then new cap on.
All the soldering was done, actually, in a clean un-used chemical fume hood at my place of work. I figured that environment would limit my smelling the solder fumes and have the least 'dust' or particulates in the air to get into my work.
