We have had some components that popped off in our IR oven. It was attributed to the solder paste. The humidity was above 60% the temp was about 70 degrees.

If you have a board that you've run several times, now you run it and like before all settings are the same, but now you have 0603's randomly skewed or an inch or so away from their intended pad (as if popped up in the air), or an occasional 7343 cap

C-SAM is a non-destructive alternative that a lot laboratories and chip manufacturers use. Dye and Pry would work I suppose although I have never done it in practice with PoP but it should be any different for PoP.

I have Electromagnetic Transport Frequency in one of my electrical physics books. Is that it? I really don't know either.

Even when you run a board several times, the machine may not make the same travel path every time. This in itself does not create a problem, but the vacuum on the nozzles could be different, dependent on the configuration of components on the heads.

We saw this condition over 3 years ago. It sometimes is called "champagne bubbles". The intemetalic formation is interrupted due to the micro voiding reducing mechanical strength. I discovered this on lead free test vehicles for a major computer
