Abstract
The purpose of this paper is mainly to develop a method to use the Taguchi method with the L 18 (2 1 × 3 7 ) orthogonal array to obtain an optimal geometrical design of the vertical probing needle and base on various criteria to minimize the stress on the probing needle during wafer-level probing test. Furthermore, importance of the factors on the probing mark area ratio was also ranked. The results shows that as probe length, offset, and lower die gap increase, stress on the probing decrease. On the contrary, vertical probe bends decrease, stress on the probe increase. Furthermore, the body of vertical probe with rectangle cross-section is better than square and circular sharp.

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
