Learn to generate high manufacturing yields, low testing costs, and reproducible designs using the latest components of surface mount technology (SMT)! Manufacturers, managers, engineers, students, and others who work with printed-circuit boards will find a wealth of cutting-edge information about SMT and fine pitch technology (FPT) in this new edition. Practical data and clear illustrations combine to clearly and accurately present the details of design-for-manufacturability, environmental compliance, design-for-test, and quality/reliability for today's miniaturized electronics packaging.

Design Guidelines for Surface Mount Technology covers the basics and the mechanics of surface mounted design technology. Surface mount technology (SMT) embodies an automated circuit assembly process, using a generation of electronic components called surface mounted devices (SMDs). Organized into eight chapters, the book discusses the component selection, space planning, materials and processes, and total concept needed to ensure a manufacturable design. The opening chapters of the book examine the significant requirements and variables affecting SMT and SMDs. The book then deals with the substrate materials specifications, including fabrication and material planning, assembly, design rules, layout guidelines, package outlines, and bar code labeling. The next chapters describe the manufacturing and assembly processes in SMDs and process-proven footprint patterns for each of the component types used, as well as guidelines for creating a suitable pattern on future products. Other chapters discuss the component spacing requirements for SMT and the generation of footprint patterns for passive and active components of SMDs. The concluding chapter describes the design criteria for maximizing machine insertion of leaded electronic components into printed circuit boards (PCBs). These criteria aid the PCB designer by detailing the considerations and some of the trade-offs that will provide reliable insertion in a production environment. Supplementary texts on surface mount equipment, supplies, and services are also provided. Design engineers and researchers will find this book invaluable.

A foreword is usually prepared by someone who knows the author or who knows enough to provide additional insight on the purpose of the work. When asked to write this foreword, I had no problem with what I wanted to say about the work or the author. I did, however, wonder why people read a foreword. It is probably of value to know the background of the writer of a book; it is probably also of value to know the background of the individual who is commenting on the work. I consider myself a good friend of the author, and when I was asked to write a few words I felt honored to provide my view of Ray Prasad, his expertise, and the contribution that he has made to our industry. This book is about the industry, its technology, and its struggle to learn and compete in a global market bursting with new ideas to satisfy a voracious appetite for new and innovative electronic products. I had the good fortune to be there at the beginning (or almost) and have witnessed the growth and excitement in the opportunities and challenges afforded the electronic industries' engineering and manufacturing talents. In a few years my involve ment will span half a century.

Focused on technological innovations in the field of electronics packaging and production, this book elucidates the changes in reflow soldering processes, its impact on defect mechanisms, and, accordingly, the troubleshooting techniques during these processes in a variety of board types. Geared toward electronics manufacturing process engineers, design engineers, as well as students in process engineering classes, Reflow Soldering Processes and Troubleshooting will be a strong contender in the continuing skill development market for manufacturing personnel. Written using a very practical, hands-on approach, Reflow Soldering Processes and Troubleshooting provides the means for engineers to increase their understanding of the principles of soldering, flux, and solder paste technology. The author facilitates learning about other essential topics, such as area array packages--including BGA, CSP, and FC designs, bumping technique, assembly, and rework process,--and provides an increased understanding of the reliability failure modes of soldered SMT components. With cost effectiveness foremost in mind, this book is designed to troubleshoot errors or problems before boards go into the manufacturing process, saving time and money on the front end. The author's vast expertise and knowledge ensure that coverage of topics is expertly researched, written, and organized to best meet the needs of manufacturing process engineers, students, practitioners, and anyone with a desire to learn more about reflow soldering processes. Comprehensive and indispensable, this book will prove a perfect training and reference tool that readers will find invaluable.

Managers, engineers and technicians will use this book during industrial construction of electronics assemblies, whilst students can use the book to get a grasp of the variety of methods available, together with a discussion of technical concerns. It includes over 200 illustrations, including a photographic guide to defects, and contains many line drawings, tables and flow charts to illustrate the subject of electronics assembly. Soldering in Electronics Assembly looks theoretically at everything needed in a detailed study, but in a practical manner. It examines the soldering processes in the light of electronic assembly type; solder; flux; and cleaning requirements. It has information on every available process, from the most basic hand soldering through to latest innovatory ones such as inert atmosphere wave soldering and zoned forced convection infra-red machines. The book provides a detailed analysis of solder and soldering action; purpose of flux and relevant flux types for any application; classification of assembly variants; assessment and maintenance of solderability. There is also a detailed analysis of soldering process defects and causes. In addition, Soldering in Electronics Assembly contains a new chapter on Ball Grid Array (BGA) technology. - A practical guide for the industry covering all the main soldering processes currently in use - Cleaning, faults, troubleshooting and standards are all major topics - Considers safety and solder process quality assessment

Printed circuit boards (PCB) are at the heart of every electronic product manufactured today. Yet, engineers rarely learn to design PCBs from a class or course. They learn it by doing, by reading app notes, watching YouTube videos and sitting by the side of an experienced engineer. This book is the foundation building book for all engineers starting out to design PCBs. It teaches good habits designing a PCB, first for connectivity, and secondly, introduces the four most important principles to reduce noise. A seven-step process is presented: developing a plan of record, creating a Bill of Materials, completing the schematic, completing the layout, completing the assembly, conducting bring up and troubleshooting and documenting the project. Each step is developed in detail. In particular, the emphasis in this book is on risk management: what can be done at each step of the process to reduce the risk of a hard-error which requires a complete re-spin, or a soft error, which requires some sort of on-the-fly repair. After connectivity is designed, it’s important to develop good habits to minimize the potential noise from ground bounce, power rail stitching noise, stack up design and reducing switching noise in signal paths. These techniques apply to all designs from 2-layer to 8-layer and more, for bandwidths below 200 MHz. The best practices for manual lead-free soldering are presented so that everyone can become a soldering expert. The best measurement practices using common lab instruments such as the DMM, the constant current/constant voltage power supply, and oscilloscopes are presented so that common artifacts are minimized. Features in the design that help you find design or assembly errors quickly and the troubleshooting techniques to find and fix problems are introduced. Applying the habits presented in this book will help every engineer design their next circuit board faster, with less chance of an unexpected problem, with the lowest noise. This textbook will also have embedded videos to visually demonstrate many of the hands-on processes introduced in this book.
