Works on old enough boards - double-sided mostly. Multilayer boards
have thicker plating and smaller effective-diameter through-holes.
Doesn't work well if the leads are clinched.
Personally, I reflow the board over a solder pot that's overfilled, and
remove the ICs with a chip puller (to keep my hands away from them, and
to provide enough grip to make clinched leads release). I have recovered
a few pounds of 41256 chips that way (from boards that were previously
stripped of other things) and a wad of things off ISA motherboards.
