Proc. ASME. InterPACK2022, ASME 2022 International Technical Conference and Exhibition on Packaging and Integration of Electronic and Photonic Microsystems, V001T04A003, October 25–27, 2022
Paper No: IPACK2022-97452
... characteristics of undoped SAC105 and doped SAC-Q solder alloys at low operation temperatures (−65°C to 0°C) at high strain rate after varied thermal aging periods up to one year. In addition, the evolution of Anand parameters for SAC solder alloys after prolonged thermal aging has been studied. The Anand model’s...
