The goal of an EMC design review is to pre-emptively find board design issues that can lead to failures during EMC testing.
In this video recording, you’ll get an over the shoulder look at how I conduct an EMC design review. This particular review took over 2 days to complete, but the process and key findings have been condensed down to a 2 hour video.
The board used for this case study is pretty complex, with the following features:
- 14 layers
- 18 power supplies (many are switch mode)
- 2 high speed ICs (One FPGA and one CPU)
- Several high speed interfaces: Gigabit Ethernet, SATA, PCI-e, USB
In the review, I cover SMPS design techniques to lower the probability of conducted and radiated emissions failures, high speed digital design, power and ground planes and nets, return path issues and much more.
I hope you can use the pointers and examples to apply the same methodology to your next design!
