Description : The impetus to create this book originated from several concerns. One of these was the perceived value to the industry of a collection in one volume of a wide range of information pertinent to the reasons and techniques for de fluxing printed wiring assemblies (PWAs). This book is expected to be of use not only to those engaged in the electronics packaging industry but also to those in related fields seeking information concerning viable methods of dealing with one of the en vironmental issues of our time: the destruction of the ozone layer surrounding and protecting the planet with which we have been entrusted. The volume of information relative to providing PW As free of residues ad versely impacting operation, reliability, and life of electronic products is grow ing, and it will continue to expand at an accelerated rate as we seek to match our technology needs and desires with our environmental responsibilities. At the time ofthis writing, which has spanned the latter portion of 1989 and early 1990, the issue of choosing a new approach to producing PW As free of detrimental residues while using environmentally acceptable manufacturing techniques ap peared to be the major concern of the vast majority of those involved in the printed wiring assembly industry. To many this meant the use of different clean ing media and/or process or equipment enhancements; to others it meant the elimination of the need to clean through materials or process changes.

Description : Contamination problems have become a major factor in determining the manufacturability, quality, and reliability of electronic assemblies. Understanding the mechanics and chemistry of contamination has become necessary for improving quality and reliability and reducing costs of electronic assemblies. Designed as a practical guide, Contamination of Electronic Assemblies presents a generalized overview of contamination problems and serves as a problem-solving reference point. It takes a step-by-step approach to identifying contaminants and their effects on electronic products at each level of manufacture. The text is divided into four sections: Laminate Manufacturing, Substrate Fabrication, Printed Wiring Board Assembly, and Conformal Coatings. These sections discuss all aspects of contamination of electronic assemblies, from the manufacture of glass fibers used in the laminates to the complete assembly of the finished product. The authors present detection and control methods that can help you reduce defects during the manufacturing process. With tables, figures, and fishbone diagrams serving as a quick reference, Contamination of Electronic Assemblies will help you familiarize yourself with the origination, detection, measurement, control, and prevention of contamination in electronic assemblies.

Description : The ELFNET Book on Failure Mechanisms, Testing Methods, and Quality Issues of Lead-Free Solder Interconnects is the work of the European network ELFNET which was founded by the European Commission in the 6th Framework Programme. It brings together contributions from the leading European experts in lead-free soldering. The limited validity of testing methods originating from tin-lead solder was a major point of concern in ELFNET members' discussions. As a result, the network's reliability group decided to bring together the material properties of lead-free solders, as well as the basics of material science, and to discuss their influence on the procedures for accelerated testing. This has led to a matrix of failure mechanisms and their activation and, as a result, to a comprehensive coverage of the scientific background and its applications in reliability testing of lead-free solder joints. The ELFNET Book on Failure Mechanisms, Testing Methods, and Quality Issues of Lead-Free Solder Interconnects is written for scientists, engineers and researchers involved with lead-free electronics.
