Component Reliability for Electronic Systems
RF Cafe Quiz #37

RF Engineering Quizzes - RF CafeAll RF Cafe quizzes would make perfect fodder in employment interviews for technicians or engineers - particularly those who are fresh out of school or are relatively new to the work world. Come to think of it, they would make equally excellent study material for the same persons who are going to be interviewed for a job.

Click here for the complete list of RF Cafe Quizzes.
Note: Some material based on books have quoted passages.



Component Reliability for Electronic Systems This quiz is based on the information presented in Component Reliability for Electronic Systems, authored by Titu-Marius I. Bajenescu & Marius I. Bazu. Published by Artech House. Note: Some of these books are available as prizes in the monthly RF Cafe Giveaway.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
