iNEMI to hold tin whiskers conference

May 16, 2007

The International Electronics Manufacturing Initiative (iNEMI) will hold its tin whisker workshop at the Electronic Components & Technology Conference (ECTC) on May 29 from 8:00 a.m. to 5:00 p.m. at John Ascuaga’s Nugget in Reno, Nev. The workshop is co-sponsored by ECTC and the IEEE Components, Packaging and Manufacturing Technology Society.

Tin plating has been and continues to be the preferred surface coating for the leads on electronic components. But tin-based plating is susceptible to the formation of needle-like protrusions or whiskers, and whiskers can potentially cause significant problems. They are especially a concern for applications requiring high reliability and long useful life.

The workshop agenda will cover:

Data on the effects of temperature and humidity on whisker formation
Data collected over several years in manufacturing
Material considerations that either encourage or inhibit whisker formation
Measuring stress in tin film and the relationship of stress to whisker growth
Recommendations for mitigation practices, including conformal coatings
Tools and methodologies for measuring stress
Progress toward a unified theory for whisker formation

CAD/CAE Model Clean-Up: Reduce Iterative Cycles
This webinar featured research and survey results related to problems associated with preparing CAD geometry for CAE applications. We discussed how Recipe-Based Automation can help create "just-in-time" CAE-ready geometry each time a cad model is updated. Watch the Presentation

Light Matters: Systems Level Approach to HBLED illumination applications
Its good practice to apply a systems-level approach to high-brightness LED (HBLED) illumination applications. Minimally, the system includes the optical, thermal and electrical characteristics of the of the HBLED, the lens (if any) which is built-in to its package, secondary optics such as external plastic lenses/reflectors to direct the light as your application requires and power driver electronics.
