Quoted from ChrisHibler:Here's what I do. I haven't torn a through hole since I started doing this.
1. Clip the leads of the existing cap close to the board.
2. Add solder to the leads, creating a small "dome" of solder
3. Heat both leads simultaneously with a broad iron tip. I have a "spade" type tip that can stretch across 9X .156 header pins at one time. It was pricey, but worth it since I perform this action so frequently on boards sent to me for repair. If you don't have a wide tip, use two irons. Heating the pads alternately and "rocking" the part is a poor substitute.
4. Once the solder on both pads is molten, see if light pressure can be used to "rock" the part out. If more than light pressure is required, then the through hole solder isn't completely melted.
Here's a video I posted using the tip to remove headers...nice.
Rock on...

Wow, that's a lot quicker than desoldering each pin individually. I wonder if weller has anything comparable to that tip.
