What type of soldering Tool do you recommend I find that using a 40 watt pencil (Radio Shack sells an inexpensive one) and some Chemtronics solder wick (available from Digi-key) works well to get the solder out of the holes. You may also need to apply a bit of solder flux in order to heat the solder properly and get it to flow. Do not grind the pencil into the hole. Solder flux is a liquid that comes in a little bottle, often with a brush attached to the inside of teh lid. But, flux needs to be removed when you're done, so if you use flux, you'll want some flux remover, though swabs and alcohol will work in a pinch to clean it up. Another method, which may be easier is to use a pin (sewing pin). Set the board on its edge. Holding the pin in one hand, rest the point against one of the solder filled holes. Now, apply the hot soldering pencil to the other side of the hole. When the pin sinks into the and meets teh tip of the soldering pencil, move the pencil slightly to the side, and continue to push the pin through. Keep the pencil touching the edge of the hole and the pin as the pin slides through. When the pin is sticking out a good distance, remove the pencil and leave the pin. After the solder has cooled (a few seconds) remove teh pin. The solder will not stick to it (or shouldn't). Now most of the solder will be sticking up in a volcano shaped structure making it easy to remove with pencil and wick/braid. The above method is a little tricky dexterity-wise. You may need to employ your chin or teeth to help steady the board. I recommend the Chemtronics desolder braid because I think it works better than the more commonly available Easy-Braid. But that may be my imagination. It's hard to make an objective comparison. One you have the solder out of the holes, installing the pins is pretty easy. I use a 15 watt grounded Radio Shack (blue handle, ~$8) soldering pencil for the installation. >3. Is it worth all this, for a slight performance gain or is it? I can't speak to that question. But I think Will S. has already recommended a software solution which is probably a better choice (certainly cheaper in terms of not buying tools) for most folks.
