We are very delighted to have Dr. Min Zhang in this episode. Min is an independent EMC consultant based in the UK. Today, we'll be talking about EMC, both on board and off the board. It will be a very interesting discussion because we will look a little bit deeper at the system level of the board.
Show Highlights:
- Zach met Min at EMCLive 2021
- Let’s hear more about Min’s background and his early exposure to EMI issues
- Earlier in his career, he worked with big companies as a motor drive engineer and power electronics design engineer for 10 years
- He started his engineering consulting business, Mach One Design EMC Consultants 2 years ago
- His first experience dealing with EMI issues was at the university while doing research for his PhD
- The lack of education in the university in regards to EMI issues is one of the reasons that sparked Min’s interest in EMI
- The university he went to specializes in motor and power converter design, but did not offer any solutions in fixing the EMI issues
- Min recalls being fascinated by his first time seeing an EMI diagnosis kit composed of the spectrum analyzer, lots of ferrites, and cable shooting copper tape in a suitcase
- It was his first time seeing a step-by-step diagnosis and troubleshooting EMI issues - checking the grounding, checking the bonding, and applying ferrites at the right place, performed by his friend’s father who was then a principal engineer in the European Space Agency
- Min’s recommendation to design engineers solving EMI issues is to understand the fundamentals – “only when you understand the fundamentals, understand the basics, and the first principle, then you can really design a system” - Min Zhang
- What happens when EMI problems exist off the board and they interfere with the system or create so much noise that the system is never going to pass EMC?
- Min answers by recommending Rick Hartley's famous YouTube video about grounding
- He continues with his answer with an example involving a three-phase brushless DC motor drive
- How to deal with cables connected to another system that is outside of the shielding?
- Shielding is a good solution, but understanding fundamentals are necessary to avoid increased cost, weight, and also the bending ratio would be affected
- Min shares a recent video he did with Robert Feranec which discusses the topic of EMI troubleshooting on immunity
- 70% of the EMI issues are somehow related to resonance
- For high-speed design, PCB designers really need to understand how the wave propagates
- Ferrite is not a 100% inductive component
- Min recommends the book by Douglas Smith – High Frequency Measurements and Noise in Electronic Circuits which focuses on the test and measurements in terms of high-speed design
- Other experts to learn from in terms of EMI troubleshooting and high speed designs are Eric Bogatin, Steve Sandler and Heidi Barnes

The OnTrack Podcast is pleased to welcome Ken Wyatt (also known as the ‘EMC Doctor’). Ken began his career as a designer in the aerospace industry, and later worked for Hewlett Packard, where he found that his background in RF and Microwave engineering helped prepare him for his role as an Electromagnetic Compatibility (EMC) Engineer. His work has since taken him all over the world, where he develops and provides in-house training and delivers presentations and live demonstration; definitely unique among presenters!
Retiring early in 2008, Ken has since become a prolific author, co-authoring three books, including his latest, in which he identifies why products fail to meet EMI/EMC regulatory standards: ‘EMI Troubleshooting Cookbook for Product Designers’.
Ken currently provides seminars on a variety of EMC related topics—touching on subjects not often taught at the university level. He also provides EMC consultation, EMC compliance and precompliance testing, design reviews, and training services for commercial, military/aerospace, scientific, consumer, and computing industry sectors.

- ‘EMI Troubleshooting Cookbook for Product Designers’—a quick look at the book Ken co-authored with Patrick G. André.
- Addressing the prevailing trends in stackups and board design in general.
- Old habits die hard: Why the PCB is the heart of most EMI and EMC issues today, and pitfalls to avoid to move past these issues.
- Signals as the flow of electrons in copper traces and wires: How our education may have left out the whole story with respect to high frequency design.
- How simultaneous trends toward diminishing device size and the Internet of Things contributes to desensing and other issues on PCBs.
- Staying “in the know”: Keeping up with our evolving understanding of the physics of PC boards and signal propagation is always challenging. Ken lays out some ways designers can stay up to speed.
- Why Electromagnetic Compability programs at the university level are few and far between, and how Missouri University of Science and Technology stands out among them.
- Case Studies: The trouble with dog trackers and blood transfusion machines. Ken discusses some challenges he’s come across in the field.
