WebAug 22, 2014 · As shown in Fig. 2 a–d, the interfacial IMC is an intermetallic compound between Sn and Ag in the as-wetted sample. Based on the Sn-Ag binary phase diagram in Fig. 3, the IMC can be determined to be Ag 3 Sn. Additionally, Ag 3 Sn can be found inside of the bulk solder. WebDec 10, 2024 · As solder joints are being scaled down, intermetallic compounds (IMCs) are playing an increasingly critical role in the reliability of solder joints, and thereby an in-depth understanding of IMCs microstructure evolutions in micro-joints is of great significance. This study focused on coarsening behaviors of Ag3Sn compounds in Sn-3.0Ag-0.5Cu …

WebNov 1, 2016 · These Ag3Sn particles have a diameter of 1 μm to 2 μm. The initial Cu6Sn5 intermetallic phase is slightly thicker as compared to the Sn60Pb40 solder joint with 0.6 μm. Furthermore, the initial Ag3Sn layer is between 0.8 μm to 0.9 μm, which marginally exceeds the initial Ag3Sn thickness of the Sn60Pb40 solder bond. WebIt was found that bulk Ag 3 Sn intermetallic compounds (IMCs) separated out only in the slowly cooled Sn-4.0Ag solder. This would be explained by the strong kinetic undercooling, arising from the rapid cooling conditions, which leads to the actual eutectic point shifts in the direction of higher Ag concentration.
