Climatic Reliability of Electronics: Global Challenges and Perspectives

– The 6th International Seminar

4-5 March 2021
Online via MS Teams

Today, electronic systems are exposed to all climatic conditions depending on the place of use. Use of power electronics for various applications is a typical example, as well as the use of electronics in the automotive sector. The device needs to be highly reliable under extreme 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 or on other components under climatic exposure. Therefore, knowledge based design for climatic reliability and developing preventive strategies are important. Irrespective of whether the system is low power or high power, basic mechanisms operating under humid conditions have many similarities. There are several possibilities for preventive measures based on extrinsic methods keeping low humidity level or intrinsic methods by increasing the robustness of the PCBA and components.

Following the previous years successful seminars, we are pleased to announce the 6th (virtual) seminar on climatic reliability of electronics. The two days seminar will cover various aspects of humidity issues in electronics. This is a focused seminar with only invited talks delivered by experts from industry and academia on various issues. We are delighted to invite you to attend this seminar.

Topics for the seminar will 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
  • Humidity issues related to electrification and e-mobility
  • Packaging design for climatic reliability
  • Moisture modelling and climate modelling for prediction of humidity effects
  • Preventive measures: Intrinsic reliability of PCBA, coatings, and extrinsic methods to control humidity in the device
