Hi all,

Anyone got any tips on how to avoid the unpleasant situation where you
try to de-solder a part on an elderly board and end up removing more than
just component leads? Most of the stuff I work on is at *least* 25 years
old and things start to get fragile.

thanks


At least you don't need fume extraction as no throat-grabbing noxious
PbF stuff.
Go around each blob with fresh multicore solder, heating just enough to
introduce some new solder, but no great depth.
Then long nose pliers on the other side of the board and as much tug as
you can give, while reheating the solder. Repeat for each pad.
