Climatic Reliability of Electronics: Global Challenges and Perspectives

– The 5th International Seminar

5-6 March 2020

DTU Lyngby

2800 Kgs. Lyngby

During the past couple of decades, use of electronics have increased in gigantic proportions. Use of power electronics in various sectors is a typical example as well as electrification of automotive sector. The device needs to be highly reliable for use in various climatic conditions. Humidity can cause reliability issues in electronics resulting in intermittent malfunctions and permanent failures; many of them are due to transient water film formation on PCBA surface under climatic exposure. Therefore understanding, finding preventive measures, and design for humidity robustness is important. There can be extrinsic methods keeping humidity level low or intrinsic methods increasing the robustness of the PCBA and components. As such preventive measures can be individually or used in combination.

Following previous years successful seminars, we are pleased to announce the 5th international seminar on climatic reliability of electronics. The two days seminar will cover various aspects of humidity issues in electronics elucidating failure mechanisms, influencing factors, humidity and climate modelling, and various preventive measures. This is a focused seminar with invited talks delivered by experts in various areas from industry and academia on various issues.

There will be extended focus on networking between participants during the evening programmes. The seminar attracts delegates from academia and industry. We are delighted to invite you to attend this important seminar. 

Seminar topics intended to cover, but not limited to:

  • Corrosion reliability issues of electronics and failures mechanisms
  • Humidity Issues related to low power and higher power electronics
  • Humidity effects on PCBA: Material, component, design, and process aspects
  • Electronic component level reliability issues
  • Enclosure aspects in controlling humidity issues
  • Moisture modelling and climate modelling for humidity effects prediction
  • Preventive measures: Intrinsic reliability of PCBA, coatings, and extrinsic methods to control humidity in the device
