Features: This book studies and analyzes some of the issues that need to be addressed in the PCB design stage to achieve electromagnetic compatibility (EMC) for electronic products from an engineering practice perspective. The book is divided into 9 chapters. Chapter 1 briefly introduces EMC standards and basic knowledge of PCB design; Chapter 2 introduces design measures such as bypass, decoupling, and energy storage required in digital circuit design; Chapter 3 covers characteristic impedance of traces and transmission line termination techniques; Chapter 4 discusses the special signal lines in digital single boards—clock design; Chapter 5 addresses power supply design issues on the board; Chapter 6 introduces grounding techniques and grounding implementation on PCBs; Chapter 7 covers electrostatic protection design implemented on PCB single boards; Chapter 8 discusses design issues related to holes and connectors on PCBs; and Chapter 9 introduces special design considerations for large-area single board backplanes, bottom plates, etc. While introducing key design knowledge points, the authors have compiled typical problems encountered in real products into case studies, placed in corresponding chapters for readers to reference. In the appendix, the book presents ideas and countermeasures for solving EMC test projects of complete products, and provides common review criteria for PCB design in the form of a review outline for hardware design, PCB design, and quality assurance personnel to use for self-checks and design reviews. This book integrates practice and theory, summarizing the key points of EMC design for digital circuit PCBs, making it suitable for engineering technicians involved in system design, logic design, hardware design, and PCB layout. It is also suitable for test engineers and technicians, personnel engaged in electromechanical product processing, manufacturing, and compatibility debugging, EMC design engineers, as well as those responsible for managing and controlling hardware engineering design.
