Abstract:
Silver sintering technology is one of the most promising high performance lead-free die-attach technologies. The work presented focuses on the thermo-mechanical and electrical performance evaluation of double side sintered modules. Die and clip attachments are processed with pressure assisted Argomax(r) silver sintering technology developed by Α Assembly Solutions. Power cycling tests following automotive requirements (200A, 5s ON and 10s OFF, until failure) and thermal cycling tests (liquid to liquid, -55deg C/+165deg C, 3 minutes dwell time for 1000 cycles) were applied to the devices. Thermal impedance measurements along with optical observations (metallographic and CSAM analysis) showed a significant increase of the 650V/200A IGBT device reliability when compared with best in class solder technology.
