I am happy that you work in a shop that can build boards right the first time on a consistent basis. Unfortunately, I would say that every place I have been at, we have had a hard time meeting class III standards day in and day out without some kind

Are you sure that you are getting adequate nitrogen flow up through the cap? If your pump isn't seated properly, you may have nitrogen escaping. Also, I have two different height nitrogen bases. The shorter one does not allow as much gas to escape

Contaminating lead-free solder connections with lead is generally a bad idea, but that's not what you plan. You plan to add tin to your tin-lead solder connection. We don't think there is a significant problem for most applications. Adding tin will
