Abstract
In this paper, the mechanical properties of multiple Sn - based bump are compared. In the experiment, the bumps with different contents of lead, such as 90Pb10Sn of high lead, 60Pb40Sn of medium lead, 37Pb63Sn of low lead and Sn 1.8 Ag of lead-free were selected to investigate the influence of lead-tin content ratio on mechanical behavior. After the preparation of whole bumps, high-temperature storage tests were carried out for different bump, and then the shearing stress test through pushing ball was carried out for the all bump at different timeline, and the morphology of the shearing end face was observed.
