[R-390] Another newbie question...

[Sheldon Daitch]

Far to many years ago, when I had a job with the  USAF at Robins AFB, I went to a 40 hour
school on NASA soldering techniques.

I seem to recall if you could not see the weave of the strands of the stranded wire on a terminal,
there was too much solder.

Hi

Yes they were soldered. They *may* have been soldered by NASA trained techs. The objective there was to use as little solder as possible in order to create a connection. Anything past that was "dead weight".
