This book provides the basic essentials and fundamentals of electronic packaging technology. It introduces the language and terminology, as well as the basic building blocks of information processing technology such as: a) printed wiring boards and laminates, b) various types of components and packages, c) materials and processes, d) fundamentals of reliability and relevant reliability enhancement methods, and e) typical failures observed are described. A fully tested semiconductor device is the starting point for this text, thus no background in the semiconductor design or fabrication is assumed. The reader is exposed to the interaction and convergence of various disciplines such as chemistry, physics, materials science, metallurgy, and process engineering in the fabrication of an electronic appliance. The reader is also made aware of the emerging trends in electronic packaging to prepare him or her for the near-term miniaturization and integration of technology trends.
