CLINTON, NY — Indium Corporation’s Strategic Advisor Dr. Dongkai Shangguan will deliver a keynote presentation on interconnect reliability at the IEEE Symposium on Reliability for Electronics and Photonics Packaging (IEEE REPP) in a hybrid event on Nov. 9-10, Santa Clara, Calif., US., and online.

Interconnect reliability is critical to the reliability of semiconductor packaging and electronic systems. As newer forms of interconnects emerge to meet the demand for high density and high performance, interconnect reliability is becoming more complex and more critical.

The growing adoption of heterogeneous integration leads to increased diversity of interconnects (with different geometries, materials, and interfaces) in the same package, with complex (and often interactive) reliability failure modes and mechanisms. Finer pitch interconnects in advanced packaging are more susceptible to failures due to electromigration, interfacial reactions, etc. Cu direct bonding, without solder, presents new considerations in interconnect reliability.

At the same time, as electronic products become more pervasive in application, interconnect reliability must be considered holistically with regard to environmental conditions, from mechanical and thermomechanical to electrical and electrochemical. These considerations will impact reliability engineering for semiconductor devices, from design for reliability to accelerated testing and analysis. Yet another important dimension for interconnect reliability involves sustainability of electronic products, which demands environmentally friendly materials and processes, such as no-clean soldering, lead-free soldering, low-temperature soldering, etc.

Understanding of the failure mechanisms for different interconnect materials is of great importance to interconnect reliability and, ultimately, reliability of semiconductor devices and electronic systems.

Dr. Shangguan is a strategic advisor to Indium Corporation. In this role, he works on specific trends related to the advanced semiconductor packaging and SMT industries, and applies his significant industry experience to supporting customers. Dr. Shangguan is an IEEE Fellow and IMAPS Fellow, and has served on the boards of directors for several professional organizations and industry associations, including IPC, IEEE EPS, and iNEMI. He also serves as a Distinguished Lecturer for IEEE EPS. He has been honored with some of the industry’s most prestigious awards, including IPC’s President’s Award, the Society of Manufacturing Engineers’ (SME) Total Excellence in Electronics Manufacturing Award, the Outstanding Sustained Technical Contribution Award from IEEE EPS, and the William D. Ashman Achievement Award from IMAPS, among others.

Dr. Shangguan received a bachelor’s degree in mechanical engineering from Tsinghua University, China, an MBA from San Jose State University, Calif., and a Ph.D. in materials from the University of Oxford, U.K. He has held postdoctoral positions at the University of Cambridge, U.K., and the University of Alabama, and has served as a guest professor at several universities. Dr. Shangguan has published two books and more than 200 scientific papers and technical articles, and has given numerous presentations to share knowledge and expertise with the industry. He is the inventor/co-inventor of 28 U.S. patents and several foreign patents.
