Indium Corporation's Dr. Ning-Cheng Lee, vice president of technology, will present two SMTA webtorials on Feb. 10 and 17.

Dr. Lee's presentation, Electromigration—The Hurdle for Miniaturization and High Power Devices, discusses critical aspects regarding the electromigration of solder joints, including failure mechanisms, the effect of solder alloy composition, solder joint metallurgy and configuration, pad design and composition, current density, temperature, and current polarity. Dr. Lee will also share recommendations on how to achieve extended life of solder joints and redistribution layers under high current-stressed conditions through optimized designs.

Dr. Lee is a world-renown soldering expert and an SMTA Member of Distinction. He has extensive experience in the development of high-temperature polymers, encapsulants for microelectronics, underfills, and adhesives. His current research interests include advanced materials for interconnects and packaging for electronics and optoelectronics applications, with an emphasis on both high-performance and low cost of ownership.

SMTA webinars and webtorials provide opportunities to learn about the latest information on electronics assembly and advanced packaging without leaving the office. For information or to register, visit
