They should teach this kind of stuff on the university. That's a thousand times more useful than most other things.

This is PCB design gold. Saving this to reference over and over again. Lots of great information and it's delivered in a way that is easier to understand than digging through all my books. Thanks for this!

On resonances in cavities and ground stitching vias.

An analogy came to mind. It's like if you had a container with water. By swinging it back and forth with some frequency, you could easily achieve huge water oscillations.

But. If you divided that container by partitions into many small containers, you wouldn't be able to achieve that huge water oscillations at that frequency.

This is how ground stitching vias, by partitioning big cavities into smaller ones, prevent resonances in PCBs.


Thank you, Robert, for your videos! They are extremely useful.

The most informative video on PCB design I have ever come across. You asked the right questions, and the guest was very experienced and prepared.
This one should be included in the curriculum for any aspiring PCB Design Engineers.
Thank you for the great work.

You have done so much for the PCB community. Thank you! And thank you, Rick!
I do have a comment about routing high speed signals in the middle of the board (in order to get the power delivery near the surface). At speeds above 10gbit the via stubs will create significant  problems (reflexions) which will require backdrill.

Thank you Robert. Your talks with experts like Rick Hartley and Eric Bogatin are videos that I visit every few months. Very grateful...

This is a very important job you're doing, Robert. It's great that there is now a good source for all the nitty-gritty details of designing a good PCB. Kudos!

My favorite guest, Rick Hartley!

this Q&A style is very helpful, I only understood it the second time Rick has explained if after your questions

Hi, Robert! Could you share with us the Rick's presentation on this topic? It seems to be extremely useful.

Incredibly valuable knowledge shared in this video. This will change the way I tackle my board stack-ups in the future, although I can't imagine I'll ever need to worry about such high density concerns. Definitely this should give me more confidence when I press the "place order" button.

You have done so much for the PCB design community and the people who are new to this that saying thank you would be an understatement now. Please keep doing the great work and teach people how to be a good electronics engineer.
Love to Rick Hartley and you both ❤️.

Great video. Rick Hartley has really changed the way we think about EMI!

Robert and EEVlog are my favorite EE YouTubers, but you two have very different styles...

Very very very very very and again very good! Thank you Robert and Rick, this video should be like a mantra for a PCB designer! And remember, the energy is... on the field!

Great video! Your lessons and discussions are so valuable for me as someone just starting out with PCB design professionally.

Thank you Robert, for sharing this video conference with Rick. Even though I am not into multi gigabit designs it made me more conscious of the effect of fast rise times. Most of the boards I design are 2 and 4 layers and looking at this video made me realize I have to be especially mindful of digital signals with fast rise times on these low layer count boards and minimize the EMI effect. Thank you for that.

I came back to this video to double check how to handle a 4 layer stack up, nice material, thanks !

Rick Hartley the man himself

I saw a similar presentation by Rick at PCB conference years ago. i was amazed then and still am now. Thanks for putting this up so i can re watch a million times =D
