Synchrotron radiation imaging technique is applied for thermomigration study.

The thermotransport of Cu in Sn has been modelled using FEM.

Higher temperatures enhances the rate of increase of cold end intermetallic compound size.

The smaller cold end Cu6Sn5 in Sn–3.5Ag than Sn may be attributed to the role of Ag3Sn.
