Abstract
ABSTRACT This paper describes a particular incident which occurred on a 360 pin, 1.27mm pitch plastic ball grid array (PBGA or BGA). Early on in our use of this part, we received reports of intermittent field failures. The failure was described as a “blank screen” or “dead on arrival” defect, meaning there was no functionality in the product. The Root Cause Analysis (RCA) department confirmed this defect but reported that they could make the product “boot up” by putting pressure on the processor (the part that this study focuses on). Analysis and inspection led us to the corner connections on the part. This paper describes this analysis, reports on the findings and makes specific recommendations on how to avoid this defect in the future.

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
