EMC Design/Troubleshooting

Get your dB down

This webinar series provides detailed information on dealing with EMC/EMI control measures from incorporating control layout and control components at the concept phase of product design. Many product designs involve purchased assemblies with little or no EMC control so the troubleshooting phase of this series is vital to identifying issues.

This series provides vital information for the design team that includes electrical, mechanical, test, fabrication and overall production to maintain a qualified product.

Introduction to EMC, EMI, and Troubleshooting Philosophy (45 minutes)

August 16, 2017: 11:00AM ET (8:00AM PT)
Presented by Ken Wyatt

We’ll explore some of the basics of EMC, the difference between EMC and EMI, EMC standards, and a systematic approach to resolving EMI issues with products, including the source – path – receptor (victim) model, the four possible coupling paths, and how to organize the information to solve EMI issues quickly.

Important EMI Product Design Concepts (1 hour)

August 30, 2017: 11:00AM ET (8:00AM PT)
Presented by Ken Wyatt

This module will concentrate more on the fundamentals of EMC and how it applies to product design. We’ll discuss how energy from digital signals move through PC boards, why discontinuous return paths are so bad, differential- versus common-mode currents, coupling paths, proper cable shield termination and pigtails, shielding tips, and hidden antenna-like structures. We’ll follow this with some interesting case studies. Plus video demos!

Radiated Emissions Fundamentals and Pre-Compliance Testing (Part 1, 1 hour)

September 7, 2017: 11:00AM ET (8:00AM PT)
Presented by Ken Wyatt

We’ll continue with the importance of wavelength, differential mode emissions versus common mode emissions, why high-speed digital signals can cause emissions, analysis of clock harmonics, and measuring emissions. We’ll describe how to start assembling your own EMI troubleshooting kit, along with acquiring low cost spectrum analyzers and probing tools. We’ll show you how to construct your own near field probes and how to use them to identify energy sources and potential coupling paths. Plus video demos!

Radiated Emissions Fundamentals and Pre-Compliance Testing (Part 2, 1.5 hours)

September 28, 2017: 11:00AM ET (8:00AM PT)
Presented by Ken Wyatt

Picking up where we left off in Part 1, the discussion continues with current probes and why they are so important to help diagnose radiated emissions. We’ll show you how to build your own current probes and how to use simple antennas for measuring and troubleshooting emissions. We’ll discuss a simple three-step process for analyzing the source – path – antenna structure that may be causing your product to fail. Finally, we’ll show you how to set up a radiated emissions pre-compliance range at your own facility, along with several selected EMI troubleshooting techniques to help analyze radiated.

Workbench Immunity Testing and Troubleshooting (1 hour)

October 25, 2017: 11:00AM ET (8:00AM PT)
Presented by Ken Wyatt

We’ll concentrate on radiated immunity, as that is by far the most common of all the immunity issues. Several low-cost broadband and narrow band RF sources will be shown, including low cost walkie-talkies and small pocket-sized frequency synthesizers that have proven themselves as valuable troubleshooting tools. We’ll also briefly cover conducted immunity, electrically fast transient (EFT), and surge testing that can be done in-house. We’ll finish this segment up with the use of low cost TEM cells for both radiated emissions and radiated immunity troubleshooting.

Electrostatic Discharge (ESD) Testing and Troubleshooting (1 hour)

November 1, 2017: 11:00AM ET (8:00AM PT)
Presented by Ken Wyatt

In this final module we’ll cover ESD testing and troubleshooting. We’ll start off with some basic testing techniques, discuss product design aspects to help control the path of ESD current, show you several low-cost tools to help in the troubleshooting process. We’ll show you how to construct your own ESD detector and follow up with several case studies of some difficult ESD problems. Plus video demos!

System Integration Webinar

Integration of Control Measures

November 2, 2017: 11:00AM ET (8:00AM PT)
Presented by Steven Ferguson

This session makes use of the design and troubleshooting tutorials presented during this series and adds discussion of implementation. Topics include:

  • Shielding materials and effectiveness along with controlling shield leakage (ventilation, holes, clamshells, and various openings)
  • Component variances and the hidden schematic
  • Gasket implementation for effective treatment of slots and seams
  • Wiring and cable management to avoid filter bypassing and controlling the loop area
  • Filter pin connectors for low speed and high speed signal lines.
  • Transient control – pros and cons of various device types
  • Developing the EMC Control Plan to provide the overall approach for the entire design team and to bring test and production into the product development and manufacturing phase of the product life cycle
