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 : As device sizes in the semiconductor industries are shrinking, they become more vulnerable to smaller contaminant particles, and most conventional cleaning techniques employed in the industry are not as effective at smaller scales. The book series Developments in Surface Contamination and Cleaning as a whole provides an excellent source of information on these alternative cleaning techniques as well as methods for characterization and validation of surface contamination. Each volume has a particular topical focus, covering the key techniques and recent developments in the area. The chapters in this Volume address the sources of surface contaminants and various methods for their collection and characterization, as well as methods for cleanliness validation. Regulatory aspects of cleaning are also covered. The collection of topics in this book is unique and complements other volumes in this series. Edited by the leading experts in small-scale particle surface contamination, cleaning and cleaning control, these books will be an invaluable reference for researchers and engineers in R&D, manufacturing, quality control and procurement specification situated in a multitude of industries such as: aerospace, automotive, biomedical, defense, energy, manufacturing, microelectronics, optics and xerography. Provides a state-of-the-art survey and best-practice guidance for scientists and engineers engaged in surface cleaning or handling the consequences of surface contamination Addresses the continuing trends of shrinking device size and contamination vulnerability in a range of industries, spearheaded by the semiconductor industry and others Includes new regulatory aspects

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 : The essaysthat comprise thisvolume were written over the period of some ten years, for different purposes and on different occasions, but they are unitedby a number of features, which this preface may serve to indicate. While the collection begins with a translation drawn from the fourth p- sentation of Hobbes's political thought, namely, the Latin Leviathan of 1668, after The Elements of Law (1640), De Cive (1642 and 1647) and the English Leviathan of 1651, the focus of the essays is largely on theEnglish version of his masterpiece of political philosophy. It isthe center of gravityinthe twenty eight years spanninghis departure from England for exile in France in 1640 till the publication in 1668 of the Latin Leviathan,withits lengthy and c- plex Appendix. The translation andintroduction of theAppendix, previously published,appears here with several revisions and additions, as does the essay 'Thomas Hobbes and the EconomicTrinity. ' A second feature common to these essays isthe deliberate attempttomake sense of thereligious elements inHobbes's thought, bothintheir own rightand inrelation to his politics and natural science. These themes are woven together in complex ways. For instance, objecting to the use of Greek philosophic language and concepts to interpret the doctrines of the Christian religion, he propounds what he takes to be a more thoroughly scriptural interpretation, in pursuit of the goal of demolishing the basis for anypower.
