This is the method we were taught in my apprenticeship in the '60s and was the approved method for aircraft electronic equipment. The NASA standard today isn't significantly different.

Hi Frank,
Interesting you mention the importance of a separate flux. I'd come to this conclusion on my own when soldering larger gauge wires >2mm, but fascinating to see it was taught as good practice on a routine basis. (Although I can't see the point with tiny SOIC IC leads, for example, these days.)
I'd also got in the habit of cleaning the entire soldering iron tip in flux by dipping, after every four or five joints, in plumber's flux, on heavier work.
What (more appropriate) flux would you recommend for the method you describe?
