Professor Rajan Ambat

 

Biography: Dr. Rajan Ambat is currently Professor of Corrosion and Surface Engineering at Division of Materials and Surface Engineering, Department of Mechanical Engineering, Technical University of Denmark. He is also the Manager for the Centre for Electronic Corrosion (CELCORR) and CreCon Industrial Consortium on climatic reliability of electronics at DTU and Research Manager for the Corrosion node of Danish Hydrocarbon Research and Technology Centre. Key research activity in his group is on humidity robustness of electronics focussing on understanding the effect at component, PCBA, and Systems level, elucidating failure mechanisms, controlling parameters and models, and intrinsic and extrinsic methods to improve reliability. Presently he is also the Chairman for the Working Party on Corrosion reliability of electronic devices under European Federation of Corrosion. He is part of the editorial board for various corrosion and electrochemistry journals and held visiting professorship and other academic positions/responsibilities in many universities. Presently he is Honorary Professor of Amity University, India. He has published more than 250 scientific papers, patents, and other contributions.
Robustness and reliability of electronic systems used as part of green transition technologies are challenged today due to several corrosion failure mechanisms caused by harsh environmental conditions. These conditions include climatic exposure such as humidity and temperature variations and other atmospheric pollutants. For some applications, exposure conditions can be as severe as offshore. Sustainable electrical energy production, conversion, and use is most important today as part of renewable energy, E-mobility, information technology and for other technological sectors. Efficiently functioning electronics systems are key to attaining this goal, while they are used under broader service boundaries as part of various technologies.

This talk provides an overview of how corrosion of electronics, especially for power electronics, due to exposure to harsh environmental conditions affects its performance as part of various green transition technologies and some information on prevention possibilities.
