To be able to understand and develop the cause-and-effect relationship of problems, it is also necessary to understand more about surface mount components, printed circuit boards, and the basic process. The first chapter of this book provides an overview of the major components families and some of the issues that are important for finding and preventing problems. Following this chapter there are successive chapters on printed circuit boards (PCBs) manufacturing process flows and details, test, and inspection. There are chapters discussing the details of workmanship guidelines and troubleshooting methods. This latter chapter includes both SPC methods and useful information in an "artificial intelligence/expert system" format. It represents several years of working with SMT and solving problems to increase yield. It summarizes the important points to understand to facilitate troubleshooting in a methodical and successful manner.
Troubleshooting in the context of this book means more than just "finding and fixing" defects. It also means the prevention of defects, as it is well known that rework/repair processes, even performed with the best of equipment and procedures, introduces some reliability risk. Also, troubleshooting means reducing cost and operating more efficiently, so there are many tips included to achieve a better product at lower cost. Table of
