Whenever I teach soldering to someone, I try to keep it short - and tell that the only things they really need to know is
1) Keep the surfaces of the two metals you want to solder clean. That means removing rust, oxidation, dirt, etc. If possible, make a mechanical connection.
2) The three metals (surface A, surface B, solder) need to be equal temperature.
9 out of 10 times, the solder errors I see are due to the above points. It is important to purchase an iron that can get hot enough for the things you want to solder together, and which can control the temperature well enough.
- atoav 4y agoYeah the most common mistake is actually not cleaning well and not heating all things up that need to be heated (e.g. trying to use the soldering iron like a "brush").
- CarVac 4y agoWhen I instruct people to solder, I emphasize that heat transfer improves when you press very firmly with the soldering iron tip. Too bad most PCB holders are flimsy. I recommend a solid metal vise instead of those contraptions.
