This course is intended for those who are involved in the design, analysis, material selection, manufacture and test of microelectronic components, printed circuit/wiring boards and assemblies. Participants will receive an understanding of the various reliability tradeoffs in electronic packaging.
Dr. Abhijit Dasgupta, Professor of Mechanical Engineering at the University of Maryland, has conducted over 20 years of research on Physics of Failure (PoF) approaches for developing reliable, complex multi-functional systems that perform electronic, photonic, and mechanical functions. This research, sponsored by a consortium of leading electronics builders/users at the Center for Advanced Life Cycle Engineering (CALCE), focuses on industry-relevant projects in reliability assurance of electronic systems, MEMS, sensors, actuators, and ‘smart’ composite systems. Examples include avoidance of failures caused by thermal and power cycling, multi-DoF vibration, shock/drop, combined stresses. He applies these PoF principles to develop effective virtual qualification tools, for optimizing manufacturing process windows, for real-time health monitoring and prognostics, and for devising quantitative accelerated testing strategies used in qualification and quality assurance of complex electronic and electromechanical systems. He has consulted for many major electronics manufacturers, published over 250 journal articles and conference papers on these topics, presented over 35 short workshops nationally and internationally, served on the editorial boards of three different international journals, organized several national and international conferences, and received seven awards for his contributions in materials engineering research and education. He has critically evaluated the use of HALT/HASS test methods and has presented PoF seminars and workshops at Hobbs Engineering over the past 15 years.
