TIP: Another method which works well for clearing solder from holes (especially on repairs like AC Jacks on laptops) is to use compressed air to clear melted solder from holes. A quick blast with a duster can works well (I have even used a drink straw in a pinch and blown out with a blast of air from mouth). Heat the solder until it liquefies, put the duster straw right above the solder and quickly hit the melted solder with an air blast to instantly clear the hole of solder. This works well on very small holes as melted solder does not always push out cleanly with metal tools. You have to be quick with the air blast because the solder re-hardens rapidly.
