Validation of different SAC305 material models calibrated on isothermal tests using in-situ TMF measurement of thermally induced shear load

摘要

In the past, a large number of material models for Sn-based solder alloys have been proposed, which are usually calibrated based on the material testing under isothermal the conditions. However, their ability to map the lifetime differences depending on the temperature rate under the field and test-lab conditions, as well as on the mean operating temperature, is still not completely investigated and validated.
