PCB Layout Rules Checklist: https://predictabledesigns.com/pcb-layout-rules-checklist-yt3

I am a software engineer slowly transitioning to PCB design. This channel has been a gold mine. Thank you

It is quite funny that "return path" is always mentioned as "plane beneath", but it may be both plane above as well as plane above and below.

This channel is very "MCU centric", where high-speed signals are common. However, many hobbyist that might be watching are in audio- or the slow analog domain, where some of these warning simply have no effect (doesn't hurt though), but in those domains noise/rf pick-up, ground-loops and mains coupling can be much bigger concerns than what was covered here.

But overall, good advice.

This might be most informative channel regarding PCB design, straight forward, pitfalls, feedback, why do it why not, awesome content honestly!

Small improvement to tip #2: if you can, keep all of your testpads in a 50mil grid

At the company I worked at many years ago we had a very good circuit layout guy.   His board designs would always pass EMI testing the first time.   For one of our low cost products we could get away with putting them in a plastic case (passed EMI testing that way) while our competitors had to use more expensive metal cases to pass.

1:20 Tip: JLCPCB includes epoxy-filled and copper-capped vias (Plated Over Filled Via / POFV) as a free standard feature on 6-layer through 20-layer PCB orders

11 Rules covered, 11 Rules learned. Thank John.

please make a video or a series of videos building a project starting from the absolutely zero hobby project to an professional project that can be turn in a commercial product

You can clearly tell, he has dealt with most of these issues in the past and knows what he is talking about. Great video.

John's tips are worth more than gold! Thanks for sharing your knowledge!

Great stuff. Thanks. I have recently been designing with ESP-32. That spec doesn't even want unclad board near the antenna. Rather they want the built-in radiator hanging out over the edge of the board, or a notch in the edge with a few mm of clearance. Oh. Wait. You showed the page from the spec! The non-Espressif devkit boards ignore this.

I love it when I finally found a nice buck converter IC (AP64060) and the VCC/GND placement is so bad that the decoupling cap has to be put on the other side.

Dude, this is gold. This is what YouTube should be about. Thank you ❤

Having a via in the pad, can also be useful to prevent tearing off the pad during a repair (low cost PCB, low cost technician or just bad luck, it happens).

i'm too inexperienced to judge this fairly, but this advice seems like gold!

4:03 “copper is free”
Out of context, that’s an interesting take

One extra thing when it comes to changing layers for high speed signals (if you absolutely have to) is to add ground vias nearby.

Thank you very much for the refresher. It's always good to be reminded of the basics.

I started my career almost 30 years ago as an embedded systems engineer, worked in that field for 1 year before moving to various roles, the last one being in corporate risk management. But still remember looking at those data sheets and not having a clue cause it was really thick 😂. I also remember that was the time that TI came out with their new quad core DSP and we were trying to build a H263 encoder off that. ( Brooktree chip was the frame grabber 😅). Quite something to have a pro explain all these tips and tricks 😂
