PCB Stack-Up and Build-Up - Phil's Lab #56

What a PCB is made of (build-up), determining a suitable build-up, and manufacturer/manufacturing considerations. Second part of video discusses how to choose a suitable stack-up for your PCB design (i.e. what sequence of layers you should assign (GND/PWR/SIG)) for signal integrity, EMI, etc.

This short presentation of stack-up and build-up has much more information than the weeks' classes.
Thank you for this video.

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!

[MatureFister]

philip, you tick all the boxes! straight to the point, but with enough explanatory words "around" the subject while staying concise. super interesting topics where you apply theory onto real world projects. great speed and easy to understand speaking. editing and and what is displayed are great, too.

[merdogan-ee-engineer]

The most crucial basics in a single video, great job! I appreciate the way you summarize these concepts

[andile]

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.

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!

Wow. This is pretty intense. I got to try making a 4 layer board sometime and use this stack concept. Thanks for sharing!

[TheLemon]

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.

[vatsan]

Wow.. This is the important and overlooked concept that I was exactly waiting for.. Much thanks Phil!!

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...!!!

Great topic and delivery,

A good PCB stackup can solve many manufacturability and performance issues.

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

[erikisberg]

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.

Thank you very much Phil's for all your videos and effort. I really appreciate all your work and time.

[thmagistr]

Thank you! As always your videos are simple to understand and contain sources for further reading.

[sagarrastogi]

I always love your videos, thanks for great content.

[CraigHollabaugh]

Excellent content. Thanks from Colorado.

[rraheem_p]

Nice video; had a interview the other day and this was asked ; luckily i understood most of the concepts

[Kyle-vqqt]

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?

[sexysmeksi]

Love your videos. I would love to see examples to the "golder rules".
