In my latest video, I reveal a simplified version of our internal EMC/EMI review process at fresuelectronics.com This is the same method we use to make sure projects are ready for certification from day one. To show you exactly how it works, we review the MINIMA carrier board, a compact open-source design for the Raspberry Pi Compute Module 5 featuring PCIe, Gigabit Ethernet, HDMI, and more. You’ll learn how to spot EMC issues early, apply practical fixes, and strengthen any design — no matter the application. Watch now and start improving your projects before they hit the lab. 👉 https://youtu.be/qLiPD1RaCec Tag a colleague who could use this! To electromagnetic enlightenment, Dario PS.

Ooops... Did it pass or not? [Butterflies in your stomach] For many electronics engineers, that’s exactly the feeling when they see a call from the EMC Test Lab. How can you feel confident when you’re dealing with what seems like black magic? That is the problem. Controlling electromagnetic interference is still seen as black magic rather than science. The result is that many engineers keep failing EMC tests with their designs and get stuck in a costly re-spin cycle. And when fixes are applied, they are often just guesses, not engineered solutions. The few engineers who have truly mastered EMI control are the ones who planned for it from the start. Your EMC test results are simply the outcome of how much attention you give to every detail of your PCB layout and system design. It is the difference between choosing a PCB stack-up that passes the first time or ending up with a bulky filter that does not fit in production. In the end, mastering EMI control is a choice. Do more (and cheaper) now, or do less (and pay more) later. You always have the choice: prevent or fix. To electromagnetic enlightenment, Dario P.S. If you are among those who prefer to prevent rather than fix at the last minute, here is the link to my academy, where we give you everything you need to make EMC a worry of the past. 👉 Join here: https://fresuelectronics.com/academy

Yesterday, we launched new tiers for the FresuElectronics Academy. To celebrate the event and thank our new members, I’m giving the EMI Control Series Guides (normally paid) for FREE to anyone who joins the Academy today. This eBook bundle combines three powerful guides I developed to help engineers stop EMI problems and build electronic systems and PCBs that meet FCC and CE standards easily. These proven methods have been used to fix EMI issues, avoid design mistakes, and pass EMC tests, keeping electronics projects running smoothly. Inside this bundle, you will learn: - The key EMC/EMI problems in electronic design and how to solve them. - The best strategies to prevent EMI and handle EMC test failures. - How to apply EMI fixes from start to finish in any project. Interested? Join the Academy here: https://fresuelectronics.com/academy To electromagnetic enlightenment, Dario P.S. Don’t wait until tomorrow to join. This is a limited-time offer.

I have read in many CMOS IC datasheets that the typical values for decoupling capacitors are 100 nF, but on the other hand I have read an article by Eric Bogatin stating that this is a false myth and that this has been going on since the 80's when CMOS IC voltages were much lower. Actually he refers to calculate the decoupling capacitors with respect to the CMOS frequency and their rise times. Could someone clarify me which is the correct way of sizing the decoupling capacitors and the technical reasoning why? I would like to clear this doubt and when I search the internet I see disparity of opinions. thanks. Translated with DeepL.com (free version)
