Re: Strange Multi-Turn Potentiometer Problem

Yes, soldering sensitive things can be challenging, but a little tip, most people say heat the object with the iron, and let the heat from the object melt the solder, that works for terminals and wire, and other larger things. But stuff that can be damaged by heat, that kills them most the time.
For those of you reading through this and wondering the correct way, what you do is put the iron on the joint, then add solder at the junction between the iron and the object. I know this sounds like it might produce a cold solder, but the flux lets the solder flow onto the work piece, and it transfers heat to it quicker than just holding the iron on would, letting the joint get done quicker. On ring board, I can get a pin on a DIP IC done in about 3 seconds. This is usually below the lead soldering time, so all turns out well.
If anyone else has a method that works, I'm not saying that is wrong, I'm just saying that this works for me.
