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.

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.

I’m a software engineer but always have been attracted to electronics. I have worked almost 4 years with low level embedded (bare metal) code for a payment related company. Loved reading datasheets and schematics. Passively learned tons from it (by asking myself what I was looking at and why it was done like this). I had to move to another field but still do a little arduino like stuff in my free time. Always wanted to give Kicad a try, especially since I got into the rabbit hole of custom mechanical split keyboards. Stumbled on Phil’s Lab videos. Next on Rick Hartley’s and now yours. Love Rick’s explanations and stories. He clearly is the rickiest Rick 🙂 Anyway I’ve learned a whole lot of exciting stuff thanks to you all. Kudos.

i took a pcb design class last semester at berkeley as an extension student. Easily one of the most valuable classes i’ve ever taken. They knew I wasn’t an engineering student, but welcomed me in anyways. They taught me how to use Kicad pretty fluently. The cool part is that we assembled all of our boards by hand after we designed them and ordered the materials; the class is jam-packed full of hands-on knowledge. I took the class at night after work, the course code is EE-198

Anecdote: one time I had to fix a layout mess of a embedded main board ~A4 sized with 400 components. The colleague was nearly "finished" (his words) and was taking parental Ieave. I strongly suggested to him beforehand use a 6L (and go to 8L if he has problems)...he chose a 4L, the GND/Power situation was horrible (signals every layer, split reference pours, ...) And I just had 3 weeks to fix that due to deadlines 🙃 Couldn't go to other stackup, as it was already reserved in the pipeline of production. As all components were on top I deleted all GND/PWR, and used strategy above. First taking care of important power and high speed signals. Due to the via power and gnd tacking it resultet in probably ~1600 drill holes (before it was more like 600 due to many the pcie connectors) That was an interesting summer😅
