[R-390] Another newbie question...

[Ed Tanton]

Yeah... I had a VERY hard time doing that somewhere around the late 70s
early 80s when I was-finally (and reluctantly by the head QC guy)-qualified.
Just goes against my grain-even if I DO understand the reasoning in

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".
