Understanding, troubleshooting and mitigating the most common EMC issues on the bench top!

Why attend our online seminar on the most common EMC issues by Kenneth Wyatt: With all the many pressures you have as a product designer, does electromagnetic compliance (EMC) always seems like a stumbling block to delaying product sales? Is your product exhibiting one of the top three failures; radiated emissions, electrostatic discharge or radiated immunity? Are you continually cycling between design/fixing – running to the compliance test lab – failing again – and back to applying more fixes? Wondering how to attack these issues earlier in the design cycle? Would you like to learn how to characterize and troubleshoot simple design issues right on your workbench? Then this is the training for you!

We’ll start with radiated emissions, because it is usually the number one challenge for most product designers. In Part 1 we’ll go over the basic theory and product “design for compliance” techniques to reduce radiated emissions. In Part 2, I’ll describe my simple 3-step process on how to characterize, troubleshoot and mitigate common causes of radiated emissions in-house and right on the bench top. Case studies included.

One of the best ways to reduce the chances of radiated emissions or a variety of immunity issues is to get the PC board design and stack-up designed properly from an EMC and signal/power integrity viewpoint. Once you understand that digital signals propagate as electromagnetic waves within the dielectric space between the circuit trace and adjacent return plane, it will all make sense. Circuit traces are waveguides!

The next module will take us through troubleshooting and mitigating radiated immunity and ESD; usually the number 2 and 3 EMC issues product designers face today. I’ve developed simple methods for locating, simulating the failures and mitigating solutions in-house, where you have plenty of resources available. No more need to run back and forth to a 3rd-party test lab to perform this troubleshooting! Several case studies will be included.

Finally, many designers are incorporating wireless technology within their products. In many cases, self-generated EMI from the board couples to sensitive wireless and (especially) cellular receivers and reduces the sensitivity to the point where the system fails basic performance criteria. In most cases, I find that broadband EMI from digital bus activity or from DC-DC converters are the main culprits and I’ll cover “ten tips” for reducing this coupled EMI. While the content is focussed on wireless, the concepts are equally valid for reducing EMI for any product. We’ll wrap up with an interesting case study.
