One of the strongest trends in the design and manufacture of modern electronics packages and assemblies is the utilization of surface mount technology as a replacement for through-hole tech nology. The mounting of electronic devices and components onto the surface of a printed wiring board or other substrate offers many advantages over inserting the leads of devices or components into holes. From the engineering viewpoint, much higher lead counts with shorter wire and interconnection lengths can be accommo dated. This is critical in high performance modern electronics packaging. From the manufacturing viewpoint, the application of automated assembly and robotics is much more adaptable to high lead count surface mounted devices and components. Indeed, the insertion of high lead count parts into fine holes on a substrate might often be nearly impossible. Yet, in spite of these surface mounting advantages, the utilization of surface mount technology is often a problem, primarily due to soldering problems. The most practical soldering methods use solder pastes, whose intricacies are frequently not understood by most of those involved in the engineering and manufacture of electronics assemblies. This publication is the first book devoted exclusively to explanations of the broad combination of the chemical, metallurgical, and rheological principles that are critical to the successful use of solder pastes. The critical relation ships between these characteristics are clearly explained and pre sented. In this excellent presentation, Dr. Hwang highlights three impor tant areas of solder paste technology.

Getting Started with Soldering not only teaches new makers and experimenters the core principles of soldering, it also functions as an excellent reference and resource for beginners and more advanced makers alike. The book guides readers through the fundamentals of soldering, explains the tools and materials, demonstrates proper techniques, and shows how to fix mistakes or broken connections. It even includes guidance on more advanced techniques such as surface-mount soldering for electronics. From choosing the right soldering iron to making perfect connections, readers will acquire the knowledge and skills needed to form a strong foundation for a lifetime of making. Soldering is a core concept in making, electronics prototyping, and home repairs The many different types of soldering -- requiring different materials and tools -- are explained with easy-to-follow instructions Full-color photographs and illustrations throughout create a visually engaging format for learning Pricing and technical considerations help readers select the best tools for their budgets and needs Troubleshooting guidelines show how to repair solder connections that have failed from improper technique or from age

Surface Mount Technology has had a profound influence on the electronics industry, and has led to the use of new materials, techniques and manufacturing processes. Since the first edition of this book was written, electronic assemblies have continued to become still smaller and more complex, while soldering still remains the dominant connecting technique. This is a comprehensive guide to current methods of soldering components to their substrates, written by one of the founding fathers of the technology. It also covers component placement, the post-CFC technology of cleaning after soldering, and the principles and methods of quality control and rework. New sections deal with Ball-Grid-Array (BGA) technology, lead-free solders, no-clean fluxes, and the current standard specifications for solders and fluxes. Dr Rudolf Strauss has spent most of his working life with a leading manufacturer of solders and fluxes. He was responsible for a number of innovations including the concept of wave soldering, and for many years has been active as lecturer, consultant, and technical author. His book explains the principles of soldering and surface mount technology in practical terms and plain language, free from jargon. It is addressed to the man, or woman, who has to do the job, but it will also be of help in planning manufacturing strategy and in making purchasing decisions relating to consumables and equipment. - Written by founding father of SMT technology - Standard specifications have been fully updated - New chapter covering Ball Grid Array (BGA) technology

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.

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.
