Thanks Phil! The best I can dream for is you bringing your talent for clear and concise explanations to the following topic: designing to protect and filter power rails. Reverse polarity, max/min voltage cut-out, max current cut-out and filtering out noise across a wide frequency range (using LC filters, or perhaps newer power management ICs). Thanks in anticipation!
Music to my ears. I came back to this video because i ran across an autodesk article on high speed RF/Analog pcb design so just wanted to get your take on it. Superbly done, Phil.
Excellent presemtation and description. I just brushed up my know how and designed a 6 layer stack up for a som carrier board. This tutorial is a very good reference to revise and refresh ur knowledge and to ensure u r doing things correctly. Thank u and keep doing such great work
I have only recently encountered your channel and I must immediately say that I am completely hooked. I particularly like the pace and style of delivery, I find I'm picking up real insights on topics I considered myself reasonably competent. I am currently dipping into several topics that I have an immediate interest in, but I'm really tempted now to delve into the DSP topic, which I had steered clear of up to this point. I'm contemplating the viability of building an Audio Signal Analyser based around one of the many DSP ICs currently available. Having come across the SigmaStudio IDE and the ADAU1701, I'm beginning to think it might be possible with a relatively small BOM. Please keep doing what you're doing Phil, lifting the veil on some truly magical engineering techniques. Based on the advice in this video, I re-did one of my previous PCBs...and gained almost 4dBs or so of useful Dynamic Range. I knew I hated switching regulators...!!!
I really enjoy a different layer combination, where, when switching from one signal layer to another you wouldn't need an extra GND via: - Signal- - GND - - Signal - - GND - The only consideration is that is can be more challenging having components on both sides of the PCB, however not entirely impossible!
Great and informative video! I I have a background in microwaves and do appreciate what You say here. Learned new things about stacking... It is interesting that what used to be the domain of specialized expensive software now can be done in mainstream PCB design software. Used to work with autocad and a gerber generators for microwave layouts. Computations where done in various software packages such as compact and similar.
Hi Phil, I’m took you Mixed Signal Hardware Design with Kicad course and learned so much! You mentioned in one of the slides that power supply filtering could be a course in its own, so I was wondering, do you plan on making a full course on that topic?
Thank you for your support, Kyle. I'm just setting up my lab and want to make videos/a course on EMI/EMC in general, which would include power supply filtering. So probably not a course focused solely on PSU filtering I'm afraid.
Very interesting as usual. I went to JLC to have a look to at 6 layers stackups. For 1.6mm thickness, the core's thickness betwwen layers 2 and 3 is 0.55 mm while it is only 0.1mm between layers 3 and 4. If I compare to your suggested stackup (19:04), my interpretation is that layer 3 (signal) will couple more with layer 4 (power) than with layer 2(gnd). As power plane is generally not a full continuous plane because of several voltages on the board, what is the solution? - find another manufacturer with smaller thickness between L2 and L3, and bigger between L3 and L4? - route L3 without "crossing" differents power planes? - this stackup will work only with a single power voltage? - my understanding is wrong and this will work wathever dielectrics thicknesses? Thanks
How to know how many layers are required to a pcb before start the routing of any pcb(for example: whether it requires 2layer or 4 layer or any other layer)
Does the story for 4 layer change if the majority of your parts are through hole components? Videos like yours are understandably very SMD centric. But I build mostly for vintage computers and such. Everything is throughhole and every pin is basically a via. After seeing this video it seems to me I could use a stack of signal/GND/Power/Signal. Just don't use the bottom signal layer (Power and top signal layer) are both close to a ground and I could always add a close gnd via to any power pins. Also what is considered a "high speed" design? high speed is so relative and no video on the subject comes even close to defining it.
Thanks a lot！I am working on a 4 layer board, and I get a little confused about whether should I change the inner layer PWR to GND. I check my design and looks like I don't need a full layer to route the power line.
This short presentation of stack-up and build-up has much more information than the weeks' classes.
Thank you for this video.
Thank you for watching, Antii!

Thank you very much for the topic ideas, Dan. Those are definitely things I want to cover in future videos!
The most crucial basics in a single video, great job! I appreciate the way you summarize these concepts
Thank you, Mustafa!

Thanks a lot for watching!
Wow. This is pretty intense. I got to try making a 4 layer board sometime and use this stack concept. Thanks for sharing!
Thanks for watching!
Wow.. This is the important and overlooked concept that I was exactly waiting for.. Much thanks Phil!!
Thank you very much!
Great topic and delivery,
A good PCB stackup can solve many manufacturability and performance issues.
Thank you very much!

Thank you ver ymuch!
Just a heads up - you can absolutely construct up to a 16-layer PCB at a standard 1.6mm thickness - not all board shops will be able to, though.
Thank you! As always your videos are simple to understand and contain sources for further reading.
Thank you for watching, Alexandros!
Thank you very much Phil's for all your videos and effort. I really appreciate all your work and time.

Nice video; had a interview the other day and this was asked ; luckily i understood most of the concepts
Awesome, hope you got the job!
I really enjoy a different layer combination, where, when switching from one signal layer to another you wouldn't need an extra GND via:
- Signal-
- GND -
- Signal -
- GND -
The only consideration is that is can be more challenging having components on both sides of the PCB, however not entirely impossible!
I also like this stack - it allows to embed sensitive signals on layer 3.
I always love your videos, thanks for great content.
Thank you, Sagar!

Very useful video. Thank you Phil!

Exactly what I needed, great content. As always
Thank you very much, Rick!
This is golden, thank you! Are you planning on doing more videos on the Xilinx Zynq board?
Thank you very much! Yes, I still want to do a video on the layout and routing of the Zynq board.
Thank you so much for this great content.
Thank you for watching, Murat!

❤ thanks for sharing
I think I missed something, what happens to PWR in 4 layer stack up? We just use PCB tracks or islands of power?
Thank you SIR
Thank you!
@@PhilsLab thank you alot (from an ex electrical engineering studnet)
Great Work again :-)
Thank you, Dean!

I'm curious why you don't use a copper fill (ie. GND plane or power plane) on the top layer
Thanks a lot！I am working on a 4 layer board, and I get a little confused about whether should I change the inner layer PWR to GND. I check my design and looks like I don't need a full layer to route the power line.
Thanks for watching, Wayne. Yeah, a lot of times you can get away with routing power rather than 'sacrificing' a layer on a four layer board for PWR.
Nice!!
Thank you, Jonathan.
should transfer-via concept be implemented on high frequency design with single-ended tracks ? 17:10
Yes, regardless of low- or high-frequency I'd advise to place transfer vias (as long as reference stays the same of course).
I don't understand why we have this massive core in the middle, isn't this a major problem?
Structural rigidity
👏👏👏👏👏
