I shall now teach you guys the best way to desolder a suface mount IC.
1. Get a Stanley knife with an absolute spanking new blade.
2. Press down gentle on each IC leg of the IC with the sharp tip of the blade till the blade has cut through the leg. It is important that you press down on the leg! Don't try it any other way.
3. Once you have cut out all the legs, whip the IC out.
4. Use a soldering iron with a flat end on the tip.
5. Rest the tip on each of the cut out leg that is still soldered to the PCB for about 2 to 3 seconds.
6. Now move the solder tip in the direction of where the IC body used to be. This will dislodge the soldered leg. Because there is no soldered component in the area where you just swiped the iron tip towards, the leg will not stick to any adjacent part.
7. If you lift the tip up now, in most cases the leg will still be stuck to the iron and you can then clean it off on a wet sponge.
8. The area from which you just removed the IC should now be cleaned with something like meths or so. Then you can just put the new IC in the same space.
9. Press down on each leg with the flat end of the solder iron tip for about 3 seconds. When you lift the soldering iron tip up the IC leg should now be soldered onto the PCB as if by magic.
Notice that at no time did I mention to use solder to solder anything. All donations are most welcome
