Can I just say that I very much appreciate you making this kind of content? I am still honing my electronics-skills and trying to build the skills for dealing with SMT-components and custom PCBs and, well, you're practically the only Youtuber who does more complex stuff than "custom PCB blinking an LED, using only through-hole components as well." I don't have the possibility of getting formal education on this, so I am left to rely on learning from whatever free sources I can -- my goal is to eventually design my own, reliable Linux-capable SBCs.

Useful video. I discovered recently that JLC don't actually do any impedance control - they just produce the board with your chosen stackup.

You sir are an internet gem. As an undergraduate deep diving into my own personal projects and projects in industry, I cannot express in words how valuable your videos are - they get me hitting the ground running faster and really allow me to start building intuition with way less stress and time consumption. I appreciate you!

[dave_dennis]

So happy to see someone else using Altium. This makes it easier for me to follow what you are doing.

[WorldOfGoobzz]

These videos are awesome. Such a great learning resource!

[Andrew-dpkf]

I would recommend Rick’s other video ‘What your differential pairs wish you knew”
That was a revelation

Hi Phil, love your videos. Waiting for your CAN Bus Firmware Design, as I'm having some issues regarding CAN Bus.

[natasha.]

Thanks Phil Phil's Lab always gives the best ttip

[Ferreira]

Great job. At last someone talks about electronics in greater detail. I can’t begin to say how frustrating it was to ask questions about these sort of subjects to the teachers and either get an odd look or a change of subject.
You are helping me to understand things that I had lost hope in getting a grasp on. Hat’s off to you, sir.

Rick Hartley makes some of the best and most informative presentations out there for PCB design. So to everyone watching this video, find a presentation by Rick Hartley and watch it ASAP! You won't be disappointed!

Also, check out the presentations by Eric Bogatin, totally worth a watch!

I have noted that the layout engineers at work will always add via fencing around the board with quite generous spacing (20h-rule). Also, they often route high-speed signals on an inner layer when they have a 10-40 layer board, keeping the top and bottom layer for components only.

I've spent the past month watching as much SI videos as possible. Though this video doesn't go into detail in literal everything (like Rick's video does), this is an excellent summary containing the most crucial tips for significantly upgrading your PCB design skill.

[Aemilindore]

Thank you. Very useful. Love those understandable tips that come with proper reasoning.

[manly]

Your videos are just amazing. Please keep up with your great work! I'm looking forward to your content and PCB design course

[MeeBilt]

Thanks a lot Phil for videos like these! Much appreciated 👍

[EdwinFairchild]

Altium has a nice automated stitching mechanism too, when you want to stitch a plane or a copper pour.

[tarasbarbos]

Hey Phil! Firstly I must say that the content you create is precious and makes a difference for many people, especially for electronics amateurs.
Can you explain why we at all need two adjacent ground planes? Would it not be the same if we had 3-layer board with a single ground plane in the middle?

[parkerd]

I sense Rick Hartley may have inspired some of this content ;)

[marek_ryn]

Thanks for another valuable video! I can't wait for full PCB design course, you promised.

[rallymax]

Still hopeful for the course you gauged interest on earlier this year. Great education as usual.

[mazenosama]

you mentioned that there are more information in books..what books did you read to be able to do such awesome and professional designs? can you tell me the titles
