This book describes the latest progress in reliability analysis of microelectronic products. The content grows out of an EU project, named  Intelligent Reliability 4.0 - iRel40 (see www.irel40.eu ).  Different industrial sectors and topics are covered, such as electronics in automotive, rail transport, lighting and personal appliances.  Several case studies and examples are discussed, which will enable readers to assess and mitigate similar failure cases. More importantly, this book tries to present methodologies and useful approaches in analyzing a failure and in relating a failure to the reliability of electronic devices.
