[Elecraft] K3 mods and methods: smt resistor/capacitor de-soldering

[Don Wilhelm]

Bob,

I have been successful using that technique, but when there is any 
difficulty with the solder re-attaching, I slide a THIN knife blade 
under the first side when the solder melts.  The blade must be thin (and 
must have a sharp edge) so the amount of lift is very small - a thick 
blade could pull the pad that is still soldered to the board.
