Monday, 25th October 2021 - EMC Education

9 AM: Keynote Speech

Speaker: Alexander Gerfer, CTO Würth Elektronik eiSos Group | Duration: ca. 15- 20 min

10 AM: Influence of PCB layout and passive components on the EMI signature of a DCDC converter

Speaker: Andreas Nadler | Duration: ca. 45 min incl. Q&A

Often the success of an EMC test is closely related to the DCDC power supply on boards. This seminar will show the influence of different PCB designs as well as the passive components on the EMC signature using a real measured DCDC converter. In addition, suitable filter strategies will be presented in order to comply with the limits of CISPR32 Class B from 150kHz to 1GHz.

11.30 AM: Magnetic Materials: External solutions to reduce EMI without redesigning

Speaker: Catedra EMC - University Valencia | Duration: ca. 45 min incl. Q&A

The control of EMI in electronic devices is an increasing issue faced by designers in order to ensure that devices comply with EMC requirements. The EMC testing process can reveal that the shielding of a certain area of a PCB or cable is needed or may even detect an unexpected EMI source. This presentation is focused on showing experimentally through some demos how it is possible to reduce EMI problems with external solutions without redesigning the electronics. These solutions are represented by magnetic shielding sheets and cable ferrites.

2 PM: Why EMC is a headache and how to avoid it

Speaker: Arturo Mediano founder of The HF-Magic Lab® | Duration: ca. 1 hour incl. Q&A

Are you a professional in the electronic business?

If the answer is yes, you are involved today in some Electromagnetic Compatibility (EMC) problem for sure. Designers, manufacturers, importers, and installers of electronic systems must demonstrate that their products do not generate or suffer from electromagnetic interference. And this is not easy!. Really, it is difficult!

Delays, unexpected costs, nerves and stress, or loss of image with a potential client, are some of the most important effects derived from non-compliance with the Electromagnetic Compatibility regulations. To avoid failing in EMC, it is critical to include EMC philosophy as soon as possible in the development stage of a product. But it is common to find companies where that strategy is not implemented as required. Let’s review what EMC is, why EMC is so difficult to comply, and how to minimize the risks of problems in this conference including real examples, technical information, and fun.

Tuesday, 26th October 2021 - EMC Design

9 AM: Signal interface filters effectivenes under real conditions

Speaker: Dr. Heinz Zenkner | Duration: ca. 90 min incl. Q&A

Problems that arise when implementing an RF filter in modern signal interfaces are discussed. Effectiveness of filters under realistic impedance conditions, via peripheral cables in comparison to the 50W-system are shown. Filter topologies are compared, the influence of filter design and peripheral cable impedance are explained. Filter topology adapted to the system, suitable components and an RF-compatible construction including layout are discussed. Critical points such as signal bandwidth, reference ground, coupling possibilities, filter construction and PCB layout are considered.

2 PM: How to Make Your Product Fail EMC Tests: Common Shielding Design Mistakes and Their Solutions

Speaker: Lee Hill Founding Partner of SILENT Solutions LLC and GmbH | Duration: ca. 1 hour incl. Q&A

In this presentation Lee will discuss and demonstrate some of the most common shielding problems that he and his business partner Randal Vaughn have seen over their 30+ years of providing hands-on EMC troubleshooting and design reviews services. As Lee discusses these problems and their solutions, he will discuss the principles that underlie good design and also how these principles are often misunderstood. Lee’s university and professional EMC courses always feature entertaining hardware demos to help the audience visualize electromagnetic concepts and eliminate the “black magic” of EMC.

You will enjoy watching and participating in this fun event produced live from SILENT’s 1080p video studio.

2 PM: System Efficient ESD Design for Robust Electronic Systems

Speakers: Bernd Deutschmann full Professor of Electronics and Head of the Institute of Electronics at the Graz University of Technology/Austria & David Pommerenke professor in the Institute of Electronics | Duration: ca. 90 min incl. Q&A

System Efficient ESD Design (SEED) address the protection of I/O against ESD using simulation. This allows to predict the robustness against damaging ESD and allows to reduce the likelihood of disturbances caused by ESD (soft-failure).

Reduced design margin due to smaller, less current carrying metallization and contacts and thinner gate oxide has reduced the design window for ESD protection to a few V and currents of less than 2 A for high speed I/O such as USB 4.x. This, and the need to use low capacitance devices (< 0.2 pF) inhibits a design by data sheet.

In simulation based design models for the TVS, which include the transient turn-on and models for the IO of the IC are combined with all passive interconnect to create a model that predicts currents and voltage at the IC for different rise time and amplitude ESD pulses.

Thursday, 28th October 2021 - EMC Production

9 AM: Do you know your component? Field behavior of different passive components

Speaker: Frank Puhane & Joanne Wu | Duration: ca. 60 min incl. Q&A

In theory, it looks quite simple how to choose the right passive components. Therefore, various literature, calculations and description are available. The dataset of the IC manufacture guides you through the process of finding the right components for the application, too. After finding the components, you will see the needed values and specification inside the datasheet of the different vendors and you can compare them. Nevertheless, are they comparable? Maybe you observe the following situation too. Everything went well at first sight, but when the application is tested at the edges, there is some unforeseen behavior. We are working with non-ideal components and there are more things to consider when using the passive components under real operation conditions. We will explain this behavior; show you these effects and will explain why they are present.
