Quoted from Wiggy:Are these tough to remove from the board, can I damage something easily?
You just have to be really careful about lifting traces and through holes when you desolder. It's really easy to overheat the joints (or underheat) and pull something off you're not supposed to.
TerryB wrote an excellent guide to soldering if you're not too familiar with the process.
