Printed Circuit Board Designer's Reference: Basics

Book Description

  • PCB design instruction and reference manual, all in one book!

  • In-depth explanation of the processes and tools used in modern PCB design

  • Standards, formulas, definitions, and procedures, plus software to tie it all together

  • Buy it to learn, but keep it as a valued reference tool!

    Printed circuit boards (PCBs) literally form the backbone of electronic devices. The electronics industry continues its spread into every aspect of modern life, yet surprisingly little written material exists about PCB standards and design. At the same time, the industry is beginning to feel the effects of a lack of new designers entering the field! To address this situation, PCB design authority Christopher T. Robertson wrote Printed Circuit Board Designer's Reference: Basics.

    This book teaches the essentials of PCB design—the same standards and techniques used in the field, but collected in one place. You'll learn most of the key design techniques in use today, and be in the perfect position to learn the more advanced methods when you're ready. On the job, Printed Circuit Board Designer's Reference: Basics will continue to serve as an indispensable reference source filled with tables, charts, and task checklists you'll definitely want to keep on hand. Rounding out the book is a valuable software package DR Resource (Designer's Reference Resource) a multifunction calculator that manages the day-to-day activities of the PCB designer, performs project management functions, and keeps vital documentation and standards data right at your fingertips. Inside you'll find:

  • Thorough coverage of PCB design tools and techniques

  • Tools for everyday calculations, useful tables, quick reference charts, and a full checklist covering the entire design process

  • Clear explanations of where values come from, how to use and adjust them, and much more

  • This book was written for new designers looking for a solid foundation in PCB design, although designers with more experience will find the reference material, software, and explanations of the values that manufacturers use invaluable as well.
