    Intermetallic compound layer and fatigue crack evolution of Bi-contained Sn-1.0Ag-0.5Cu solder under thermal aging and thermal fatigue by Junjie Zhao, Jun Wu, Jiayu Zhang, Mingqin Liao, Fengjiang Wang

    Published 2025-01-01
    “…The shear strength, intermetallic compound layer, and fatigue evolution in solder joints were then investigated under thermal aging and thermal fatigue. During isothermal aging, the size of Sn grain and intermetallic compound (IMC) thickness in solder joints were greatly decreased due to the addition of Bi, especially with 5 wt% addition because the atomic migration to produce IMC layer was hindered by the Bi diffusion layer formed at the IMC interface, which means that Bi can play a role in refining the grains. …”
