it takes a LOT of force to shift even small BGAs from those boards.
surface tension is amazing. even with the solder fulyl melted and a
sharp smack on the side of the board, sometimes the things just dont

I have a method which wont turn the board crispy black - use a hot air
gun - the type for stripping paint / wallpaper. heat the board and use a
screwdriver to push (not lift) the chip sideways. once the solder melts,
the chip will move. once it starts to move, slide the blade under the
chip and twist (gently! the boards get plyable at these temperatures)
