Discusses the growth mechanisms of tin whiskers and the effective mitigation strategies necessary to reduce whisker growth risks This book covers key tin whisker topics, ranging from fundamental science to practical mitigation strategies. The text begins with a review of the characteristic properties of local microstructures around whisker and hillock grains to identify why these particular grains and locations become predisposed to forming whiskers and hillocks. The book discusses the basic properties of tin-based alloy finishes and the effects of various alloying elements on whisker formation, with a focus on potential mechanisms for whisker suppression or enhancement for each element. Tin...
Written by one of the foremost authorities on the subject, the Second Edition is completely revised to reflect the latest changes to the ASQ Body of Knowledge for the Certified Quality Engineer (CQE). This handbook covers every essential topic required by the quality engineer for day-to-day practices in planning, testing, finance, and management and thoroughly examines and defines the principles and benefits of Six Sigma management and organization. The Quality Engineering Handbook provides new and expanded sections on management systems, leadership and facilitation principles and techniques, training, customer relations, documentation systems, domestic and international standards, and more.
The development of electronics that can operate at high temperatures has been identified as a critical technology for the next century. Increasingly, engineers will be called upon to design avionics, automotive, and geophysical electronic systems requiring components and packaging reliable to 200 °C and beyond. Until now, however, they have had no single resource on high temperature electronics to assist them. Such a resource is critically needed, since the design and manufacture of electronic components have now made it possible to design electronic systems that will operate reliably above the traditional temperature limit of 125 °C. However, successful system development efforts hinge on...
This book raises the level of understanding of thermal design criteria. It provides the design team with sufficient knowledge to help them evaluate device architecture trade-offs and the effects of operating temperatures. The author provides readers a sound scientific basis for system operation at realistic steady state temperatures without reliability penalties. Higher temperature performance than is commonly recommended is shown to be cost effective in production for life cycle costs. The microelectronic package considered in the book is assumed to consist of a semiconductor device with first-level interconnects that may be wirebonds, flip-chip, or tape automated bonds; die attach; substra...
Adopting a hands-on approach, this work shows how to achieve ISO 9000 registration efficiently and economically, through the TAP-PDSA (Train, Audit and Plan / Plan, Do, Study, Act) method. It explains issues encountered in registering, providing real examples, and addresses the functions of a registrar, the importance of choosing a registrar early, and the criteria of registrar selection. The primary goals of registration - to improve quality, achieve customer satisfaction and increase profitability - are stressed.
Walter LaFayette Bell (1889-1976) was born in Butterfield, Missouri, son of Jonas Bradley Bell (1843-1931) and Martha Ann Cooper (1865-1890). He married Ruth Rankin (1900-1975), born in Jonesboro, Arkansas, daughter of James Lewis Rankin (1854-1928) and Mary Elizabeth Dawson (1860-1912). Ancestry traced to John Bell (1668-1713) who died in Surry County, Virginia and Robert Rankin (1749-1816) of the Carolinas and Kentucky, as well as many other ancestors. Ancestors, descendants and relatives lived in Illinois, Missouri, Utah, Tennessee, Kentucky, Virginia, Arkansas, Texas, Indiana, North Carolina, Wisconsin, Iowa, Mississippi, South Carolina and elsewhere.
