Center for AdvancedLife Cycle Engineering4th International Symposium on Tin WhiskersJune 23-24, 2010Samuel Riggs Alumni CenterUniversity of MarylandCollege Park, MD, USAScopeThe Center of Advanced Life Cycle Engineering at the University of Maryland in collaboration with TheInstitute of Scientific and Industrial Research (ISIR) at Osaka University is pleased to announce the call forparticipation for the Fourth International Symposium on Tin Whiskers. Tin whiskers present a uniquechallenge to the electronics industry. There have been numbers of electronics failures in the marketcaused by tin whiskers since 1940s. After 2000, as a result of the global transition to lead-free electronics,the majority of the electronic component manufacturers are now using pure tin or tin-rich alloys forterminal and lead finishes. The increased used of tin based lead-free finishes and materials, focused concernand research on tin whiskers particular for long life and mission critical applications, such as space,aviation, and implantable medical devices.A tin whisker is a conductive tin crystal, which can spontaneously grow from tin based lead-free finishedsurfaces even at room temperature, often in a needle-like form. Oxidation in humid atmosphere, corrosion,intermetallic formation, stress under thermal cycling, external pressure in fine pitch connectors andelectromigration have been shown to promote whisker formation. However, acceleration models forwhisker growth are very limited or not existent.
