Fourth International Symposium on Tin Whiskers Call for Participation
Thursday, January 14, 2010 | University of Maryland

Brochure http://www.calce.umd.edu/istw4.pdf

The Center for Advanced Life Cycle Engineering (CALCE) at the University of Maryland, in collaboration with The Institute of Scientific and Industrial Research (ISIR) at Osaka University, is pleased to announce the call for participation for the Fourth International Symposium on Tin Whiskers.

Tin whiskers are needle-like growths that can form spontaneously on tin-based lead-free finished surfaces. Tin whiskers present a unique challenge to the electronics industry. Since the 1940s, there have been numerous electronics failures caused by tin whiskers. As a result of the global transition to lead-free electronics in the early 2000s, most electronic component manufacturers now use pure tin or tin-rich alloys for terminal and lead finishes. The increasing use of tin-based lead-free finishes and materials has lead to focused research on tin whiskers, particularly for long life and mission critical applications in aerospace, aviation and medicine, i.e. implantable medical devices.

Research has shown that oxidation in humid atmospheres, corrosion, intermetallic formation, stress under thermal cycling, external pressure in fine pitch connectors and electromigration can promote whisker formation. Despite these findings, available acceleration models for whisker growth are limited or, in some cases, non-existent.

Over the past three years, CALCE and ISIR have organized meetings to provide awareness and track new findings related to tin whiskers. A listing of proceedings from past International Symposia on Tin Whiskers can be found here.
