Check also the specs / recommendations of your PCB manufacturer. We bake boards 4h/120°C before reflow and after automated cleaning (it´s not FR4!) and also if we have to rework with the autometd rework- stations (massive IR underheating ,..). Regar

What would be a recommended way and were to attach therms for profiling on a board with a BGA or BGA's. Evtimov had mentioned drilling a hole and attaching to the BGA? We do not always get sacrificial boards when we do a job. Is attaching to the PCB

If you think the root cause is excess moisture in the pcb then try to bake it for longer. Even longer then the manufacturers recommendation. It takes a long time for excess moisture to come out of a pcb. Try 24 hours , then 36 hours and see if there
