I would like to dedicate this book to my wife, June, who was there for me during the entire book-writing process. Thanks my love.G.C.I’d like to dedicate this book to my husband, Mike, and my son, David, for their patience and understanding through the long, cranky hours spent writing and rewriting.C.A.T.
Series Editor's Foreword by Dr. Andre Kleyner
The Wiley Series in Quality & Reliability Engineering was launched 25 years ago. Since then, it has grown into a valuable source of theoretical and practical knowledge in the field of quality and reliability engineering, continuously evolving and expanding to include the latest developments in these disciplines.
Each year, engineering systems are becoming more complex, with new functions and capabilities and longer expected service lives; however, the reliability requirements remain the same or become more stringent due to the increasing expectations of product end users. With the rapid development of autonomous vehicles and growing attention to functional safety, these expectations have grown even further. It will require the utmost reliability to convince people to entrust their lives to an “inhuman machine”; only by using new visions, methods, and approaches to develop engineering systems – and electronic systems in particular – will this become a reality.
The book you are about to read was written by experts in the field of electronics design and manufacturing. Cheryl Tulkoff and Greg Caswell, whom I have the privilege to know personally, have a depth and variety of experiences covering virtually every aspect of design for reliability and quality manufacturing of electronics. This book presents an easy‐to‐read, step‐by‐step guide to designing, testing, validating, and building highly reliable electronic systems. It also addresses sustainability and obsolescence – the flip side of fast IC evolution and miniaturization – which are significant issues for electronic systems designed to operate for long periods, such as those in fields such as automotive, airspace, defense, etc.
Despite its obvious importance, quality and reliability education is paradoxically lacking in today's engineering curriculum. Few engineering schools offer degree programs or even a sufficient variety of courses in quality and reliability methods. Therefore, most quality and reliability practitioners receive their professional training from colleagues, engineering seminars, publications, and technical books. The lack of formal education opportunities in this field highlights the importance of technical publications such as this one for professional development.
We are confident that this book, as well as the entire series, will continue Wiley's tradition of excellence in technical publishing and provide a lasting and positive contribution to the teaching and practice of engineering.
Foreword
First and foremost, this book is an invaluable technical gem – front‐line experience pours out of it to those (like me) who are listening. This is a work as spoken, not as written or read, from a voice who has seen and knows electronics design, manufacturing, and reliability from the beginning looking forward and the end looking back; and who has gained knowledge from experience, intelligence, and maybe even a few mistakes. Those are laymen's terms for the complex and critical technical and commonsense details that distinguish Designing for Excellence in Manufacturing from the more common “Design it and throw it over the wall to manufacturing” approaches.

Preface
With our combined 80+ years of experience in electronics manufacturing encompassing integrated circuit fabrication, printed circuit board fabrication, circuit board assembly, and work in materials, packaging, processes, and standards, we feel uniquely qualified and privileged to author this book.
Our inspiration to write it came from peers, clients, and students in the electronics industry. Through our work with them, we realized we were answering the same questions, solving the same problems, and seeing the industry make the same mistakes over and over. We found that both unfortunate and discouraging. We were unable to find a comprehensive how‐to guide and felt we had a unique opportunity to help prevent problems from recurring.
We wrote this book for electronics design, manufacturing, and reliability engineers and those who work with them. We wanted to create a practical guide containing tools, tips, and solutions to help engineers create high‐quality, high‐reliability products. We sincerely hope we have succeeded.

Acknowledgments
The authors would like to thank the engineering teams at Ansys‐DfR Solutions and National Instruments for their support during the development of this book. We would particularly like to thank Dr. Craig Hillman, Dr. Nathan Blattau, Jim McLeish, Dr. Randy Schueller, and Seth Binfield for exceptional technical input in their areas of expertise. Their contributions made the book a more comprehensive resource.
We would like to recognize Ken Symonds for performing a detailed review of the entire book and offering numerous editorial comments that significantly enhanced it. His input on grammar and complexity also made the book infinitely more readable.
Andre Kleyner provided the critical initial nudge and persistent support in driving us to make the book a reality. Ella Mitchell at Wiley secured the technical reviews for us at the concept stage and made sure all of the important paperwork got done.
We'd like to express our gratitude to our peers and students from the electronics industry organizations that we have taught and volunteered for over the years, including IPC, SMTA, iMAPS, IEEE, and ASQ. Their questions, feedback, and knowledge have greatly informed this book.
Finally, we would like to thank our respective companies and families for giving us the time to bring the entire manuscript together. We hope you find it useful.
