Soldering Handbook for Printed Circuits and Surface Mounting, Second Edition, covers every aspect of this packaging technology, and contains the latest information on design, presolder operations, materials, equipment, surface mount technology, cleaning, quality and inspection, touch-up and repair, process economy, line management, and more.

The printed circuit industry has achieved maturity and universal accep tance. No known interconnection technology threatens to render it obso lete in the foreseeable future. It offers two unique advantages that are important for any assembly technology: quality (reliability) and economy. The mode of component attachment to printed circuit boards, however, is undergoing a radical change. Technical and economic pressures are forcing the industry to convert some or all of its assembly to surface mounting techniques. We are moving away from the traditional large through-the-hole connection with its mechanical security. It is being re placed by a small surface butt and/or lap joint, sometimes with no added mechanical support to the solder. This change requires a complete reas sessment of design, production, and inspection techniques. A major por tion of this book is devoted to the changes imposed by surface mounting. This recent development is an extension of the established hybrid (thick and thin-film) industry. Yet when it is applied to conventional printed circuits, there are major differences. One must view the printed circuit board as a planar surface designed to provide interconnections between electronic devices. The electronic in dustry is using them for mass-production techniques to join discrete, integrated, and special components (leaded and leadless). This book ap plies to all board variations including single-sided, double-sided, multi layer, and flexible circuits.

Newnes Electronics Assembly Handbook

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.

Libraries that serve special science-oriented and vocational high schools are featured in this important new book. These libraries--largely unknown even in library circles--have developed special collections and services to meet the needs of students whose main interest is science or vocational training. The contributors to this exciting volume are librarians who work in science-oriented and vocational high schools. They share information on the special collections, services, students, activities, and problems that challenge them as they work in some of the countries finest school libraries.

This book is a one-stop guide to the state of the art of COB technology. For professionals active in COB and MCM research and development, those who wish to master COB and MCM problem-solving methods, and those who must choose a cost-effective design and high-yield manufacturing process for their interconnect systems, here is a timely summary of progress in al aspects of this fascinating field. It meets the reference needs of design, material, process, equipment, manufacturing, quality, reliability, packaging, and system engineers, and technical managers working in electronic packaging and interconnection.

Volume 1: Packaging is an authoritative reference source of practical information for the design or process engineer who must make informed day-to-day decisions about the materials and processes of microelectronic packaging. Its 117 articles offer the collective knowledge, wisdom, and judgement of 407 microelectronics packaging experts-authors, co-authors, and reviewers-representing 192 companies, universities, laboratories, and other organizations. This is the inaugural volume of ASMAs all-new ElectronicMaterials Handbook series, designed to be the Metals Handbook of electronics technology. In over 65 years of publishing the Metals Handbook, ASM has developed a unique editorial method of compiling large technical reference books. ASMAs access to leading materials technology experts enables to organize these books on an industry consensus basis. Behind every article. Is an author who is a top expert in its specific subject area. This multi-author approach ensures the best, most timely information throughout. Individually selected panels of 5 and 6 peers review each article for technical accuracy, generic point of view, and completeness.Volumes in the Electronic Materials Handbook series are multidisciplinary, to reflect industry practice applied in integrating multiple technology disciplines necessary to any program in advanced electronics. Volume 1: Packaging focusing on the middle level of the electronics technology size spectrum, offers the greatest practical value to the largest and broadest group of users. Future volumes in the series will address topics on larger (integrated electronic assemblies) and smaller (semiconductor materials and devices) size levels.

Solders have given the designer of modern consumer, commercial, and military electronic systems a remarkable flexibility to interconnect electronic components. The properties of solder have facilitated broad assembly choices that have fueled creative applications to advance technology. Solder is the electrical and me chanical "glue" of electronic assemblies. This pervasive dependency on solder has stimulated new interest in applica tions as well as a more concerted effort to better understand materials properties. We need not look far to see solder being used to interconnect ever finer geo metries. Assembly of micropassive discrete devices that are hardly visible to the unaided eye, of silicon chips directly to ceramic and plastic substrates, and of very fine peripheral leaded packages constitute a few of solder's uses. There has been a marked increase in university research related to solder. New electronic packaging centers stimulate applications, and materials engineering and science departments have demonstrated a new vigor to improve both the materials and our understanding of them. Industrial research and development continues to stimulate new application, and refreshing new packaging ideas are emerging. New handbooks have been published to help both the neophyte and seasoned packaging engineer.
