Information related to thermal ratings and characteristics in the part datasheets influences decision-making regarding the use of components. Inconsistent and incomplete information in the datasheets can lead to incorrect decisions in the part selection and management process, which adds costs and delays product development. Users fail to recognize the flaws in the information presented in the datasheets and assume it to be complete.

In this presentation, we discuss the impact of the missing information on decision-making regarding component selection. An analysis is conducted on representative datasheets selected across select component classes to identify those inconsistencies and incompleteness in reporting thermal information in the datasheets. Based on this analysis, this webinar will discuss the necessary information that should be included in part datasheets and other technical documentation and how such information enhances the process of part selection and management, and integration of parts into a system.

About the presenters:

Harsha Walvekar is a graduate research assistant and an M.S. student at the University of Maryland. She received her Bachelor of Engineering degree in mechanical engineering from the Visvesvaraya Technological University, Bangalore, India. She worked as a mechanical design engineer focusing on component selection and new product design in the automotive industry before returning to graduate school. Her thesis focuses on component selection for electronics applications, including the use of parts beyond manufacturer-provided ratings.

Dr. Diganta Das is an Associate Research Scientist at the Center for Advanced Life Cycle Engineering. His expertise is in reliability, environmental and operational ratings of electronic parts, uprating, electronic part reprocessing, counterfeit electronics, technology trends in electronic parts, and parts selection and management methodologies. He has been the technical editor for two IEEE standards and is currently vice chair of the standards group of the IEEE Reliability Society. He is a group leader for the SAE G-19 counterfeit detection standards group.

He has been the Founding Chair of the CALCE/SMTA Counterfeit Parts and Materials Symposium since 2007. He is chair of the SAE committee developing counterfeit product detection standards. He also participates in several other SAE standard developments related to counterfeit electronics.
