The objective of this book is to better understand why components fail, addressing the needs of engineers who will apply reliability principles in design, manufacture, testing, and field service. It so contributes to new approaches and the development of electronic and telecommunications component reliability. As a reference source, it summarizes the knowledge on failure modes, degradation and mechanisms, including a survey of accelerated testing, achieving better reliability, total quality topics, screening tests and prediction methods. A detailed index, a glossary, acronym lists, reliability dictionaries and a rich specific bibliography round the benefit offered by the book. The technical level suites to senior and graduate students, as well as to experts and managers in industries.
