Have to agree with Martin C. The hardest thing to learn is how to solder properly. These are tiny, VERY tiny points you are soldering. Practice on something you are not going to use anyway...like an old MB. You can read, read, read look at YouTube vids all day long, but until you practice, practice, practice you run more risks of just tearing stuff up. Martin is always....ALWAYS helpful. I would recommend always following his advice.
