Re: [amsat-bb] NASA SPEC Connectors

Bob,

Crimp connections (if done properly) are better than solder 
connections.  If you are using stranded wire and attempt to solder it 
the solder will wick up into the wire and not allow the wire to flex 
at the pin.  If subjected to vibration the wire will break off 
eventually.
