“An incisive history” of how a bicycle messenger service in Seattle became a global behemoth, and the labor battles along the way (Dissent). We may see their trademark brown trucks everywhere today, but few people know the behind-the-scenes story of United Parcel Service and how it became one of America’s most admired companies. This book reveals how UPS managed to displace General Motors—the very symbol of American capitalism—to become the largest private-sector unionized employer in the United States; its long, tumultuous history with the International Brotherhood of Teamsters; and its effects on its workers and surrounding communities. It also explores the question of its future in the age of Amazon—as it battles to hold on to the throne of the Package King. “Get a copy of Allen’s book for yourself and then pass it on to a UPS driver the next time you get a delivery. She is part of the most organized section of what is possibly the most important industry in 21st-century capitalism, and the outcome of her story will have a lot to do with what our world looks like on the other side of this pandemic.” —Indypendent

Hermeticity of Electronic Packages is a book about the integrity of sealed packages to resist foreign gases and liquids penetrating the seal or an opening (crack) in the packageùespecially critical to the reliability and longevity of electronics. The author explains how to predict the reliability and the longevity of the packages based on leak rate measurements and the assumptions of impurities. Non-specialists in particular will benefit from the author's long involvement in the technology. Hermeticity is a subject that demands practical experience, and solving one problem does not necessarily give one the background to solve another. Thus, the book provides a ready reference to help deal with day to day issues as they arise. The book gathers in a single volume a great many issues previously available only in journalsùor only in the experience of working engineers. How to define the ""goodness"" of a seal? How is that seal measured? How does the integrity of the seal affect circuit reliability? What is the significance of the measured integrity of the seal? What is the relationship of Residual Gas Analysis and the seal integrity? The handbook answers these questions and more, providing an analysis of nearly 100 problems representative of the wide variety of challenges that actually occur in industry today.
