I desoldered a bunch of remnant computer boards this way back in high 
school (and got in trouble for filling the classroom with fumes.) I would 
put them in a vise, solder side up, heat the whole board with the torch, 
and smack the board with a hammer; everything falls out.

I still have a big pile of TTL chips left over from those days... I tested 
a bunch and the survival rate was over 90%.
