No Pain, No Gain...?
Sometimes the solder just won't come off the soldered spot, no matter how much heat you apply and no matter how well you use the de-soldering pump. We need to open a small hole for the capacitor pin at the soldered spot. So, we take a small metal pin (diameter 0.8 mm), hold it at the soldered spot with small pliers, and carefully heat it with the soldering iron. If all goes well, you will be able to remove the now liquid solder from the small hole in the motherboard. But please be careful when doing so: If you apply too much pressure to the metal pin, you might damage delicate adjacent conducting paths.
Clear the soldering spots with a metal pin.
If you're still not successful in clearing the hold in the motherboard, try drilling a hole in the soldered spot. We advise against this procedure! You should only try it, if neither de-soldering with a soldering iron, nor the metal pin approach works.
Drilling the motherboard - this should only be your last resort.
