Abstract
ABSTRACT The control of moisture-sensitive devices (MSDs) prior to SMT reflow is a critical assembly issue that has a direct impact on final product reliability and customer satisfaction as well as manufacturing costs. The guidelines for storage and handling of MSDs are clearly defined in the joint IPC/JEDEC standard J-STD-033. However, the proper identification, logging and date/time calculations have always been very challenging to implement with manual procedures and they are prone to a high level of human errors. In most cases, implementation of an internal manual control procedure requires major simplifications to the industry standard. This results in baking parts that that do not need it while assembling some that should be baked. Both will affect manufacturing and material costs while increasing the risk of early life failures in the field. The solution to address all these issues consists of an automated control system that is both simple-to-use and can insure a very high level of control. The foremost objective of the system is to avoid assembling components that have exceeded their allowable limit. This is achieved by automatically tracking each reel or stack of trays from the time they are removed from their original dry bag until all parts are placed prior to reflow. The second objective is to minimize the number and duration of bake cycles by taking into account all applicable rules from the industry standard and ambient conditions, while providing real-time status and advance warnings of expiration.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
