If your gonna use a heat gun to do repair, you have to
figure out a way to pre-heat the board prior to
applying heat to remove the chip. At that point, you
heat both sides simultaneously (Bottom of the board
gets lower heat than the top of the board). This is
how all of the hot air machines from Hart, Pace and
others work.
If you don't do it like this, layers in multilayer
boards can and will seperate. If that happens,
salvaging the board is next to impossible.
