I probably seem like an idiot that I even ask the question, but I'm going to be replacing some components on an old jukebox control board, and want to make sure I do it correctly. Can anyone recommend some good resources so that I learn correctly. I've actually soldered copper pipes with good success, but this is a completely different skill. Are there different soldering irons that are better than others? What about the solder material itself? Any ideas/recommendations would be welcome.
