A
Three-Step Process For Radiated Emission Troubleshooting Success
Most product designers know
how to use a near field probe to assess harmonic content on their boards or
system cabling. However, they often don't know how to proceed next to
resolve the actual issue. I developed a simple three-step process for
evaluating a product and drilling down to the root cause.
PC
Board Design for Low EMI
The
root cause of many design issues involves the circuit board design and
how the I/O and power connectors are arranged and filtered. Poor board
designs, interconnect placement and filtering can result in radiated
emissions, radiated immunity, and electrostatic discharge (ESD) compliance
failures, among others. Bad designs often result in endless cycles of
trial and error mitigation, compliance testing and board spins. This
drags out the schedule and is very costly. I’ll explain how digital
signals propagate in boards as electromagnetic fields. I’ll also
explain how interconnect placement and poor filtering design and layout can
affect the EMI performance. Once you understand this, then board
stack-up, trace routing, filter design and interconnect placement should
become very clear and you should be able to design a low-EMI board the first
time!
Ten Tips for Characterizing & Troubleshooting Board-Level EMI for products, including Wireless
It is fairly common to find multiple on-board sources of energy causing radiated emissions on today’s product designs, including board-level EMI for wireless portable, mobile, and IoT devices. The EMI from these energy sources can couple to cables creating radiated emissions, as well as interfere with the receiver performance of cellular, GPS and other wireless modules. This presentation describes methods for identifying, characterizing and reducing the coupling from these energy sources.
Bench Top Troubleshooting ESD and Radiated Immunity Failures
Electrostatic discharge (ESD) has started to become very common, due to the lower noise margins for digital circuits. While the test is easy to set up in-house, it can become one of the most challenging EMC issues for manufacturers to overcome, because it’s difficult to determine the path of ESD current and exactly what circuitry is being affected. In addition, radiated immunity issues have become very common and is nearly impossible to set up in-house without great expense and trained test operators. Often it involves endless cycles back and forth between adding random fixes in-house and then running back to the compliance test lab. The delay for both ESD and radiated immunity issues can negatively affect product introductions. This presentation will describe a simple method for troubleshooting and mitigating both issues right on the lab bench. Several case studies will be described.
This will be a great MiniSymposium, guaranteed to sell out

If
you are working in the EMC field, our MiniSymposium is for you! You definitely will come away with new ideas about troubleshooting techniques, specification updates and a better understanding on how to measure critical parameters. While there, browse tabletop booths of manufacturers, EMI/EMC Test Houses, and increase your knowledge of suppliers in this industry. Meet with fellow EMC Engineers and learn more about how our local IEEE EMC Chapter can assist you in your daily challenges.
