EMC: Compliance, Opportunities & Pitfalls with

On this episode of the OnTrack Podcast, Tech Consultant Zach Peterson welcomes Anton Tishchenko, aka Dr. EMC on CZcams. The two explore the intricacies of EMC design, certification, and compliance.
They chat about various aspects of EMC testing, common mistakes in PCB design, AI-integration, and how modules and antennas play a huge role in EMC compliance. Anton also shares his journey into EMC, how to approach design testing effectively, and insights into his fascinating PhD research.
Learn from this video:
• Strategies for effective EMC compliance
• Common mistakes in PCB design and how to avoid them
• The role of AI in PCB design checks
Key takeaways:
• EMC testing has a 50% failure rate on first attempts.
• Comprehensive design strategies can prevent costly EMC failures.
• Modules and antenna setups can greatly impact EMC compliance.

Great stuff guys! Thanks!

[@peterkolta1207]

Recently I got around a machining shop and connected my notebook to the outlet. First of all when the guy 30m further switched on his angle grinder the mouse started to act weird on my notebook, second of all the wifi dropped.
Is this somewhat part of EMC?
Another situation, I connect an Asus notebook to a servo amplifier via RS232, if I touch the notebook and don't have rubber shoes on the mouse of this notebook will also go crazy. Interestingly here this does not happen with eg. a Macbook.
Is this also part of EMC?
How do small companies handle EMC? I know some companies who just design PCBs and release it to the wild without EMC testing at all hoping that their volume is small enough anyway and do not cause any issues.

[@DrEMC-sf8rx]

Yes
Yes
...and Yes, with a side note that FCC requires you to log your intentional transmitter test results in an open access online portal, so you can easily find out who didn't. In the end it's the Law, and the penalties can be high enough to bankrupt the business.
I have a Macbook myself and when I was filming my recent video I tried to disrupt it with conducted transient voltages - it's exactly the scenario 1 and 2 that you described. The Macbook is built like a tank and was completely unimpressed with anything I tried up to +/-4kV. In the end, I had to switch to a Dell monitor, so that I could show what a test failure looks like :)

​@@DrEMC-sf8rx thanks for your reply.
"intentional transmitter test results"
Do you think cheap eg. angle grinders/brushed motors which cause arcing take care about that when they sell in the US or do weaker laws apply to those tools?
I'd be really interested to see an EMC compliance test with an old sparking angle grinder.
Are there different FCC requirements for industrial vs. commercial sides? More relaxed in some industrial areas? (like I mentioned that traditional machining company)

[@DrEMC-sf8rx]

@@peterkolta1207 actually you raised an interesting point that I forgot to mention in the podcast. In the US the immunity side of EMC is completely voluntary. There are ANSI standards which are equivalent of EN 61000-4-x counterparts, but the FCC only requires you to test emissions. Having said that, the electrical tools you described must still comply with the emission limits imposed by FCC, both conducted and radiated. The levels for industrial and commercial applications are indeed different, as the limits for commercial equipment are more strict.
