The paper presents improved constitutive models for SnAgCu solder. In the present study, the constitutive behavior for creep performance of 95.8Sn-3.5Ag-0.7Cu lead-free solder was investigated. The secondary creep stage was focused on. It is shown that the stress exponent n can be well-defined into...
