"Electromagnetic compatibility (EMC) is an engineering discipline often identified as "black magic." This belief exists because the fundamental mechanisms on how radio frequency (RF) energy is developed within a printed circuit board (PCB) is not well understood by practicing engineers. Rigorous mathematical analysis is not required to design a PCB. Using basic EMC theory and converting complex concepts into simple analogies helps engineers understand the mitigation process that deters EMC events from occurring. This user-friendly reference covers a broad spectrum of information never before published, and is as fluid and comprehensive as the first edition. The simplified approach to PCB design and layout is based on real-life experience, training, and knowledge. Printed Circuit Board Techniques for EMC Compliance, Second Edition will help prevent the emission or reception of unwanted RF energy generated by components and interconnects, thus achieving acceptable levels of EMC for electrical equipment. It prepares one for complying with stringent domestic and international regulatory requirements. Also, it teaches how to solve complex problems with a minimal amount of theory and math. Essential topics discussed include: * Introduction to EMC * Interconnects and I/O * PCB basics * Electrostatic discharge protection * Bypassing and decoupling * Backplanes-Ribbon Cables-Daughter Cards * Clock Circuits-Trace Routing-Terminations * Miscellaneous design techniques This rules-driven book-formatted for quick access and cross-reference-is ideal for electrical and EMC engineers, consultants, technicians, and PCB designers regardless of experience or educational background."

A very important part of printed circuit board (PCB) design involves sizing traces and vias to carry the required current. This exciting new book will explore how hot traces and vias should be and what board, circuit, design, and environmental parameters are the most important. PCB materials (copper and dielectrics) and the role they play in the heating and cooling of traces are covered. The IPC curves found in IPC 2152, the equations that fit those curves and computer simulations that fit those curves and equations are detailed. Sensitivity analyses that show what happens when environments are varied, including adjacent traces and planes, changing trace lengths, and thermal gradients are presented. Via temperatures and what determines them are explored, along with fusing issues and what happens when traces are overloaded. Voltage drops across traces and vias, the thermal effects going around right-angle corners, and frequency effects are covered. Readers learn how to measure the thermal conductivity of dielectrics and how to measure the resistivity of copper traces and why many prior attempts to do so have been doomed to failure. Industrial CT Scanning, and whether or not they might replace microsections for measuring trace parameters are also considered.

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.

Focused on the field of knowledge lying between digital and analog circuit theory, this new text will help engineers working with digital systems shorten their product development cycles and help fix their latest design problems. The scope of the material covered includes signal reflection, crosstalk, and noise problems which occur in high speed digital machines (above 10 megahertz). This volume will be of practical use to digital logic designers, staff and senior communications scientists, and all those interested in digital design.
