Climatic Reliability of Electronics:
Global Challenges and Perspectives

– The 8th International Seminar

16-17 March 2023

DTU Lyngby
Meeting Center – Meeting room 1
Anker Engelundsvej 1
2800 Kgs. Lyngby

Electronic systems are exposed to all types of environmental conditions today, as they are part of all technological applications. Power electronics are integral part of applications such as renewable energy, transportation and automotive electrification. All these systems are expected to perform in a robust and reliable manner under exposed climatic conditions.

Humidity and other environmental conditions such as gases can generate a number of electro chemical failure modes, leading to intermittent functional issues and complete systems failures. While it is important to understand the robustness and reliability of the systems under expected environmental conditions, and how that result in functional issues, an equally important aspect is the understanding of failure mechanisms and conditions and parameters causing such issues. Understanding detailed mechanisms and their connection to functional issues will allow better Pro-active design and maintenance strategies for effective control.

This seminar will focus on these issues addressing both electronics and electrical aspects together with material and corrosion aspects bringing together electronics/electrical and material/corrosion experts. Broadly, the seminar will address topics related to low/high voltage and effect of environmental conditions on failure mechanisms, technology sector wise issues, material, design, and PCBA processing aspects in connection with humidity issues, and intrinsic and extrinsic preventive strategies.

Topics for the seminar will cover, but not limited to:

  • Electronics use for green transition technologies and issues related to exposure environment
  • Environmental reliability issues related to Electrification in transportation
  • Proper test methods for higher power/voltage electronics and challenges
  • Material, corrosion and mechanistic aspects of failure modes
  • Component level corrosion issues and failure mechanisms
  • PCBA design and process connection to environmental reliability
  • Intrinsic and extrinsic preventive measures including conformal coating, climate condition-based packaging etc.

Dr. Morten Jellesen, CELCORR, Technical University of Denmark
