From Signal Integrity to EMC: Join Daniel Beeker for a Two-Day Science-Based PCB Design Seminar in Derby, United Kingdom in October 2026

Introduction: PCB Design Has Entered a New Era 

Electronic systems continue to evolve at an extraordinary pace. Faster edge rates, higher switching frequencies, compact multilayer stack-ups, dense BGAs, mixed-signal architectures and increasing reliability expectations have fundamentally changed the way printed circuit boards must be designed. In many applications, including aerospace, defence, industrial automation and medical electronics, PCB layout is no longer simply an interconnection exercise; it is a critical part of overall system performance. 

Engineers are now expected to achieve first-pass success while meeting demanding signal integrity, EMC and reliability requirements. Every additional prototype, compliance failure or late-stage design modification increases cost and delays product delivery. As a result, organisations are placing greater emphasis on understanding the engineering principles that govern PCB behaviour rather than relying solely on historical design rules. 

Many traditional layout practices were developed when switching speeds were considerably slower. Today, however, rise time is often more significant than clock frequency. A design that appears electrically correct in the schematic can still fail because of poor return current paths, discontinuous reference planes, excessive loop area, uncontrolled impedance or inadequate power distribution. 

Why Physics Matters More Than Rules of Thumb 

Rules and design guidelines remain valuable, but they are most effective when engineers understand why they exist. Science-based PCB design focuses on electromagnetic behaviour rather than memorising isolated layout recommendations. It asks questions such as: Where does the return current flow? How do electric and magnetic fields interact with the PCB structure? What effect will a split reference plane have on a high-speed signal? Why does a seemingly minor layout change create unexpected EMI? 

Core Principles of Science-Based PCB Design 

• Maintain continuous return current paths for every high-speed signal. 

• Treat reference planes as part of the signal path rather than as passive copper. 

• Plan PCB stack-ups early to support impedance control and EMC performance. 

• Reduce loop area to minimise radiated emissions and susceptibility. 

• Design the power distribution network with low inductance and effective decoupling. 

• Understand the relationship between placement, routing and electromagnetic field behaviour. 

Return Current Paths: Often Overlooked, Always Important 

One of the most common causes of EMC and signal integrity problems is an interrupted return current path. High-speed return currents naturally follow the path of least inductance, remaining close to the signal trace on the adjacent reference plane. When that reference is interrupted by plane splits, voids or poorly managed layer transitions, the return current must detour around the discontinuity. The result can be increased loop inductance, higher emissions, greater susceptibility and degraded signal quality. 

Signal Integrity, Grounding and Stack-Up Planning 

Signal integrity cannot be considered independently from PCB stack-up, grounding strategy and power delivery. Controlled impedance, consistent reference planes and carefully planned layer assignments all contribute to predictable electrical behaviour. Likewise, effective decoupling is not simply about capacitor values; placement, mounting inductance and current loops determine whether transient current demands are met. 

From Theory to Practical Engineering 

The objective of science-based PCB design is not to make PCB development more theoretical. Quite the opposite. By understanding the underlying physics, engineers can make faster, better-informed design decisions. Rather than following a checklist blindly, they can evaluate trade-offs confidently and identify potential issues before fabrication, reducing PCB re-spins and improving first-pass success. 

Daniel Beeker's Engineering Approach 

Many engineers know Daniel Beeker through his presentations, design reviews and international technical seminars. With more than 44 years of experience in electronic system design and electromagnetic compatibility, Daniel has developed a teaching style that bridges engineering theory and practical product development. Instead of presenting design rules in isolation, he explains the physical mechanisms behind them, enabling engineers to apply the same reasoning to new technologies and future designs. 

His sessions combine real-world PCB examples, practical demonstrations and engineering experience gained from decades of solving challenging EMC and signal integrity problems. This practical approach has made his seminars valuable for PCB designers, hardware engineers, SI engineers, EMC specialists and engineering managers alike. 

Benefits for Engineering Teams 

• Improve first-pass PCB success and reduce costly redesigns. 

• Strengthen signal integrity and EMC performance. 

• Understand grounding, return currents and stack-up decisions with greater confidence. 

• Reduce compliance risk before laboratory testing. 

• Develop engineering judgement that extends beyond individual design guidelines. 

Technical Seminar Hosted by Azitech ApS 

To support the engineering community, Azitech ApS, Denmark, will host the Science-Based PCB Design Seminar led by Daniel Beeker on 27–28 October 2026 at Delta Hotels Breadsall Priory Country Club, Derby, England, United Kingdom. 

The seminar is intended for experienced PCB designers, hardware engineers, EMC specialists, signal integrity engineers and engineering managers seeking a deeper understanding of the engineering principles that lead to robust, reliable PCB designs. Topics include return current behaviour, grounding, EMI reduction, signal integrity, PCB stack-up planning and practical high-speed design techniques. 

An Invitation to the Cadence Community 

The Cadence Community has long been a place where engineers share experience, discuss design challenges and exchange practical solutions. We hope this article contributes to that conversation. If the topics discussed here align with the challenges you face in your own designs, we would be delighted to continue the discussion. 

As external links may be filtered within the Cadence Community, please feel free to leave a comment or send us a direct message if you would like additional information about the seminar, agenda or registration process. We look forward to engaging with fellow engineers and learning from the wider Cadence community.
