EMC and the Printed Circuit Board: Design, Theory, and Layout Made Simple
This accessible, new reference work shows how and why RF energy iscreated within a printed circuit board and the manner in whichpropagation occurs. With lucid explanations, this book enablesengineers to grasp both the fundamentals of EMC theory and signalintegrity and the mitigation process needed to prevent an EMCevent. Author Montrose also shows the relationship between time andfrequency domains to help you meet mandatory compliancerequirements placed on printed circuit boards.
Using real-world examples the book features:
- Clear discussions, without complex mathematical analysis, offlux minimization concepts
- Extensive analysis of capacitor usage for variousapplications
- Detailed examination of components characteristics with variousgrounding methodologies, including implementation techniques
- An in-depth study of transmission line theory
- A careful look at signal integrity, crosstalk, andtermination
Why Read This Book
You will learn how RF energy is created and propagates on a printed circuit board and how to design and lay out boards to prevent EMC problems without wading through heavy math. Montrose blends clear, practical explanations, real-world examples, and hands-on mitigation techniques so you can diagnose emissions, choose proper decoupling, and apply layout fixes that improve both EMC and signal/power integrity.
Who Will Benefit
Embedded hardware and firmware engineers with basic electronics knowledge who need to design PCB layouts, reduce EMI, and meet EMC compliance for embedded, mixed‑signal, or IoT products.
Level: Intermediate — Prerequisites: Basic circuit theory (Ohm's law, capacitors, inductors), familiarity with PCB layout concepts and components, and practical experience with embedded hardware or electronics assembly.
Key Takeaways

How It Compares
Like Henry Ott's Noise Reduction Techniques, this book is practical and hands-on, but Montrose focuses more narrowly on PCB layout and capacitor strategies, whereas Johnson & Graham's High‑Speed Digital Design emphasizes signal integrity for very fast digital systems.
