What type of flux do you use and how do you apply it? Right now I
use some pinkish / red stuff from RioGrande, it seems to work
If the pinkish stuff is Magic Flame, that’s my favorite. You can mix
it with water or alcohol, and I like the latter. You have to swish it
around, but the alcohol just burns off and doesn’t cause things to
move out of position like water-based fluxes.
But I have half-a-dozen fluxes on hand. If the Goddess doesn’t like
one on a given day, maybe she’ll like another, or a combination.
I like to dip or spray. Or dip AND spray. On a bad soldering day,
I’ll dip in Magic Flame and alcohol, burn it off, then heat the piece
and spray on Cupronil or Firescoff or My-T-Flux.
