Low temperature sintering-bonding using mixed Cu+Ag nanoparticle paste for packaging application
Bibliographic record
Abstract
In this study,the two kinds of nanoparticle pastes were prepared by using the modified polyol chemical reduction process,respectively,and the mixed nanoparticle paste was prepared by mechanically mixing of the two pastes.The sintering characteristics of the mixed paste were investigated,and the results show that the mixed paste had good oxidation resistance.Ag-coated copper bulks were bonded through the sintering of mixed paste.The results indicate that the increasing of Ag content in the paste was beneficial to high quality of joints,and with the bonding conditions of sintering at 250 ℃ for 5 min under 5 MPa pressure,the average shear strengths of joints using nano-Cu paste,mixed paste consisting of 50% mole Ag and 50% mole Cu,and nano-Ag paste,were 15 MPa,22 MPa and 56 MPa,respectively.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
