What I do is add extra heat on the opposite side using an extra pencil 
tip solder iron , hold the board vertically[or use a vise], it helps 
control the action this way, and preheat the other side with the 
desolder iron [with the bulb squeezed tightly] for several seconds and 
then release. This also helps with the stubborn power pins on any DIP
