Abstract
ABSTRACT The purpose of this study is to examine the thermal properties of various halogen-free laminates used in handheld electronic products and to correlate these properties with the manufacturing requirements. Thermal properties investigated are the z-axis CTE, time to delamination at 260°C and 288°C and temperature to decomposition. SEM and EDS mapping analyses have been done on the laminates to determine the chemical composition and volume fraction of the fillers used in the epoxy. Three different fillers were identified: Al(OH) 3, Mg(OH) 2 and SiO 2. Results show that the SiO 2 fillers reduce the z-axis CTE and increase the time to delamination. The decomposition of the Al(OH) 3 fillers above 200oC contributes to increases in z-axis CTE and promotes delamination.

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
