“I really enjoyed ESREF in Aalborg and was very pleased with all the arrangements and the overall logistical organization of the conference at this beautiful location. I should say it was a roaring success with a record number of submissions, exhibitors and a beautifully planned out program with adequate opportunities for technical interactions and social networking. I hope to attend ESREF more consistently in the years to come and look forward to more learning experiences there with different cultural connections to different parts of Europe!”

Nagarajan Raghavan (IPFA Co-Chair, SUTD, Singapore)



“I had a great time at ESREF 2018. I learned a lot from the technical talks especially on the GaN reliability. I got chance to network with many other researchers/engineers from academia and industries. The social event at Voergaard Castle was also very well organized, served with a great food and very entertaining shows. Overall, I can say ESREF 2018 was a great success. Congratulations to all the organizers! Looking forward to attend ESREF 2019”

INVITED SPEECH
Rajan Ambat - Technical University of Denmark
Interplay of humidity and electrical functionality imposing reliability problems in electronics
Abstract
Electronic control units, power modules, and consumer electronics are used today in a wide variety of varying climatic conditions. Varying external climatic conditions of temperature and humidity can cause an uncontrolled local climate inside the device enclosure. Uncontrolled humidity together with number of other factors including the presence of hygroscopic contamination resulting from the PCBA manufacturing process can introduce deviation from desired functionality or even intermittent or permanent failure of the device. Additional factors are the miniaturization and high density packing combined with the use of several materials, which can undergo electrochemical corrosion in presence of water film formed due to humidity exposure and bias conditions on the PCBA surface. Aim of this paper is to show how the interplay between humidity (also transient changes in climate) and electrical functionality occurs, which cause several reliability issues on electronics due to electrochemical failure mechanisms.
Biography
Dr. Rajan Ambat is currently Professor of Corrosion and Surface Engineering at Department of Mechanical Engineering, Technical University of Denmark. He is also the Manager for the Centre for Electronic Corrosion (CELCORR)/CreCon Industrial Consortium on climatic reliability of electronics at DTU. Humidity related reliability issues of is a major research theme under CELCROR in close collaboration with a number of major European industries. Various research activities on climatic reliability include material, component, PCBA, and device level issues and mitigation methods. Presently he is 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/Honorary professorship and other academic positions/responsibilities in many universities.
