Priority items to confirm · 5
01Initial bonding and solder locations are definedUnconfirmed
Are these package-to-PCB BGA solder joints initially conductive, with cracks or resistance anomalies localized to the solder?
Retain initial non-coalescence, IMC interfaces, and substrate cracks beneath pads as neighboring topics; an overall open cannot establish solder fatigue.
Update engineering conditions →02Baseline and cumulative damage are traceableUnconfirmed
Do time-zero data, staged cycling electrical / crack measurements, and normal contacts share coordinates and failure criteria?
Daisy-chain totals must retain their localization limits; one final crack image does not establish a cumulative damage rate.
Update engineering conditions →03Specimen thermal conditions, support, and timing are definedUnconfirmed
Are actual specimen temperatures, dwell and ramp conditions, board support, and measurement times comparable?
A chamber setpoint is not the solder-joint or board temperature; thermal shock, passive cycling, and powered loading cannot be directly interchanged.
Update engineering conditions →04Measured geometry and material locations are comparableUnconfirmed
Can actual stand-off, ball and pad geometry, contact locations, and board / package materials be aligned?
Nominal ball diameter or board material names cannot establish local strain; hold mechanical support and package dimensions fixed before comparing geometry.
Update engineering conditions →05Material microstructure and thermal history are comparableUnconfirmed
Do solder composition, crystal orientation, microstructure, and reflow / aging histories have representative paired controls?
Availability of EBSD and material-analysis services requires separate confirmation; the same alloy name does not imply the same crystal orientation or aging. Published alloy rankings cannot be applied directly.
Update engineering conditions →Relevant assessment paths
