Tom,

For most double-side PCBs, this shouldn't be a problem with a 
solder-sucker. A somewhat counter-intuitive trick is to first add more 
solder to the pin/pad. Then heat it up well can remove the solder. 
Sometimes it may still stick a little. If you're not trying to save the 
chip, just cut the leads off and pull them out with pliers as you apply 
a little heat.  If it's a power pin and there's a huge power plane on 
the board it can be a pain since all the copper will suck the heat away.
