For “Board-level BGA solder-joint fatigue under thermal cycling”, add details that may change the assessment order and check the basis and limits of each candidate.
Engineering conditions
Confirm that board-level BGA solder joints were initially formed, then compare fatigue responses using staged damage, measured specimen loads, and material and geometry controls. Unknowns remain pending confirmation; “assessable” means only that method inputs are complete, not that a diagnosis has been made or qualification passed.
Live assessment
First add initial conduction, crack paths, and staged baselines.
Unconfirmed: Are these package-to-PCB BGA solder joints initially conductive, with cracks or resistance anomalies localized to the solder?; Do time-zero data, staged cycling electrical / crack measurements, and normal contacts share coordinates and failure criteria?First add sample temperatures, support, and staged measurements.

The order changes only with conditions you confirm. Public information cannot establish suitability for your actual samples.
After one round of comparisons, choose the next step based on actual observations.
Results only change the order of the next investigation; they do not modify condition answers, prove a root cause, or qualify a solution.
