a simple, efficient and cheap way is to make a dedicated tip for your
soldering iron to remove the socket. (material CuCrZr with 0.3/1.2% Cr and
0.03/0.3% Zr)
of course, you need then to empta the holes and hand solder the new part.
according to our experience, it works pretty well (of course, the tip will
be totally destroyed at the end)
good luck

  Subject: [TN] PLCC socket removal


  Hi TechNetters,

  I have run into a situation where I may need to remove and replace a 68
pin through-hole socket that is used to house an SMT PLCC device. The board
is .062" @ 4 layers, and the socket is somewhat isolated in a corner of the
board. Potentially, this might be done on a few thousand units. My first
thought is selective soldering. >From your experiences, whom should I
consider? Do you have any other thoughts?
  Thank you,
  Paul Black
