Dr. Jennie Hwang to Address "Tin Whisker – All You Should Know" in SMTA Webtorial Sessions


Reading time ( words)

Dr. Jennie Hwang, a long-standing leader in SMT manufacturing and lead-free implementation, will hold two 90-minute SMTA Webtorial Sessions to address tin whiskers. Dr. Hwang's presentation on "Tin Whisker – All You Should Know" will be held on December 7 and 8.

The webinar provides a working knowledge to all who are concerned with or interested in tin whisker and related issues in electronic packages and assemblies including designers, engineers, researchers, managers and business decision makers; also is designed for those who desire the broad-based information.

For the recent years, concerns about tin whiskers are intensifying although tin whisker and its potential mishaps have been recognized for more than six decades in electronic, electrical and industrial applications. The webtorial provides a holistic coverage on tin whisker from physical/phenomenal occurrence to fundamental scientific base to mitigating measures. The webtorial also explains why the tin whisker propensity under a study should be concluded with a specific alloy composition in conjunction with a specific system; and why a reference point is needed. Relative ranking of the tin whisker propensity among lead-free solder alloys in relation to SnPb alloy will be outlined.

Part 1:

  • Definition & clarification
  • Physical phenomena
  • Reference point & criteria
  • Causes and contributing factors
  • Concerns & impact
  • Reliability implications

Part 2:

  • Test conditions
  • Mitigation remedies - Relative effectiveness
  • Plausible theory / mechanism
  • Tin whisker vs. tin pest
  • Summary
  • Recommendations - prevention & mitigation
