Abstract

fetched live from OpenAlex

The efficiency of short fault isolation in flip-chip packaging has been increased greatly using the newly developed infrared lock-in thermography (IR-LIT) technique. Because the current concentration is always higher at the short location, shorts are equivalent to a heat source that can be detected by IR-LIT. This paper presents case studies using IR-LIT as a fault isolation tool and shows IR-LIT is more useful in isolating defects in flip-chip-packaged microprocessor devices than other techniques like superconducting quantum interface device (SQUID) and photon emission (PEM) microscopy. This paper also demonstrates integration of IR-LIT into the standard electrical failure analysis flow for short failures.

Teacher imitation

Not 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.
