Book Description
For those that are new to SMT or unsure about many of the aspects of SMT, this is an excellent source of information. This book covers in-depth all the topics that pertain to SMT designing. Included is information that is useful to both those new to SMT as well as those trying to convert existing through hole technology designs to SMT.

There are lots of changes from through hole to SMT. With a thorough understanding of the basics provided in this book the reader will be able to completely understand and master SMT technology.

The basics learned in this manual are the heart of "design for manufacturability" which is so important today. We must have designs that are easy to assemble and test. The design group will learn how to set up libraries and begin their designs. Coupled with knowledge about the impact of design on manufacturability, the manufacturing group will learn the basics of the process, terms, equipment, and common sequences of assembly.

Don't learn by making the same mistakes as others. This manual pays for itself many times by prevention of those common mistakes.

Who Will Benefit
This book will be of immense value to both circuit designers as well as CAD designers, and those involved in product testing, fabrication, troubleshooting and debug of products.
