Desoldering

Motherboard Solder Won’t Extract or Melt

manufacturing solder is not the same as what you get from radio shack, it melts at a higher temp. Use a high watt iron that is fully heated then melt some solder on the tip and let that get hot a sec. you can then stick the ball of melted solder over what you are trying to de-solder. the melted solder gives a higher contact area than just touching one spot on the iron (similar to tinning wires before making a joint). the goal is to get the iron as hot as possible with the greatest area of contact possible while staying on the joint. If you do not, you will have the iron on it to long and damage the board itself or a nearby component. Just to be thorough, while you are heating the joint you should be pulling out from the other side with a pair of needle nose pliers
