And pin outs of both. Once I saw a SOT-6 replaced with a miniSOT-6 (IIRC) The pin outs of the two parts were different. We did make an adaptor board and it wasn't too bad. We populated a panel of the adaptor boards, depanelized them and put them in t

Here are the nozzles that soaked, but didn't get tinned. Since the solder joints also had yellow, I am wondering if the contamination is lingering in the solder pot, and getting on the joints. The Superior is never applied to a board. In the board

Try adipic acid to clean your nozzles. It is a powder and can be awkward to work with as a result. But you might end up preferring it. Also look where the substance is not. There are two PTH joints without it. And that chip cap is closer to the PT

If it was ROHS I would suspect copper migration. In my experience an acceptable copper finish should last up to at least 6 reflow cycles. If you have bubbles or blow holes in the solder joint, that is a sign of voids in the walls of the copper barre

Thank you for sharing the helpful information. Let's say the PCB is a double-side assemble process and this PCB has completed the first reflowing SMT assembly process, is there any concern if the board is kept on the production floor with temperatur
