Yes, obviously humidity changes with temperature. I don’t see how that’s important. 99% of dead boards out there are not dead because of indoor, room temperature level humidity fluctuations, and the plenty of PCBs still working from the 70s don’t seem much affected by them either. There’s thermal cycling concerns, but that’s dominated by the board’s own heat generation. Do you have some data that would indicate that modern boards are sensitive to this?
