I have never attempted as delicate a procedure as this. I am soliciting
suggestions on how to do this without damaging the rf board.
I always use two (2) small temp-controlled soldering irons (Hakko 936).
The idea is to heat both ends simultaneously to melt the solder
without dwelling too long on the board. The parts likely have a small
amount of adhesive under them so once the solder is melted, I push one
end with a soldering iron while holding the other end still. This
breaks the part free from the adhesive.
Be certain the soldering irons aren't set too hot. 650 F is about right,
700F is probably OK, higher is a Bad Idea. There is little thermal mass
here. The worst problem will be heat flow from the grounded end of one
of the two resistors.
Or, you may have an iron with a wide enough tip to heat both ends of the
part - that will work too, just keep the temperature under control :-)
I haven't had breakfast yet so I'm not thinking clearly; the RF board
you damage maybe your own; YMMV, ...
