Abstract
Thermal management and especially cooling attracts more and more attention during phases of conception and fabrication of power modules to increase their field operation time and/or power density. Indeed thermal power losses impact the reliability of power systems, which are in a same time converging towards always higher power density and performances. Since standard solder die attach and wire bonding are reaching their limits, a novel concept of assembly has been realized with double sided cooling (DSC), as fully integrated part of the power module. Half-bridge modules either based on IGBTs and silicon diodes or based on SiC-devices have been assembled by combining Transient Liquid Phase Bonding (TLPB) and Transient Liquid Phase Soldering (TLPS). SiC and silicon wafers were prepared by deposition of a high density area array of Cu posts. In order to switch 1200V / 25A copper posts were electroplated 80 μm in height with a thin tin cap for flip chip bonding by TLPB. To attach a second DCB substrate on the backside, a TLPS paste was used. All interconnects of the modules are formed by intermetallic bonds for the target purpose of increased capability in heat dissipation, improved reliability and higher operation temperatures. Results on fabrication, thermal characterization and active power cycling (ATj = 125 K) are here also reported.

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
