Abstract:
Large sized CeSn3 and ErSn3 phases precipitated in the Sn-3.8Ag-0.7Cu-1.0Ce/Er solder alloy are oxidized when they are exposed in air, and tin whiskers can rapidly grow on the surface of the oxidized CeSn3 and ErSn3 phase. The growth behavior of tin whiskers formed on the surface of the oxidized CeSn3 and ErSn3 phases was investigated. The results indicate that not only traditional cylinder-like tin whiskers but also some special ones are observed on the surface of the oxidized CeSn3 and ErSn3 phases, such as stripe-like tin whiskers, distorted tin whiskers, tin whiskers with variable cross sections, branch-type tin whiskers, merging-type tin whiskers and jointing-type tin whiskers and so on.
