This is more of a FWIW comment. When I was in the USAF back in the
1960's we were not allowed to solder any wire splices in airplanes but
rather, used gas-tight crimp connections for the job. The logic was that
when stranded wire was soldered the solder would wick up to a point in the
wire that then became a transition between a solid and a stranded wire. This
in turn became a weak point that would break when the wire was flexed.
Supposedly, the crimp connection system overcame the wicking problem and
spread out the bending radius of the wire enough that the damage caused by
the flexing inherit from the vibration in an aircraft was minimal.
Not sure how this applies to soldering vs. crimping coax connectors but
it might be important if a connector is subject to much flexing or
vibration.
