Keys to Control Noise, Interference and EMI in PC Boards - Hartley

[@nameredacted1242]

THIS NEEDS TO BE IN THE LIBRARY OF CONGRESS, AND REQUIRED TEACHING FOR EVERY ELECTRICAL ENGINEER!!!

[@Andrew-dp5kf]

I could listen to this guy all day long. Such a great lecturer.

[@HansBaier]

Yes he does not get boring for a second

[@AdamWright88]

@@HansBaier he was very descriptive in talking about how he'd choke the guy out who didn't put the reference designators in order.....very colorful, haha...definitely got my attention

Great lecture and video! Quick question... at time 41:17, you can see that 12.3 mm is the critical length on inner and 13.6mm is critical length on outer trace. But I'm confused because wouldn't this contradict the earlier point that signals travel faster on outer (in comparison to inner) layers? So wouldn't you expect the critical length to be longer on outer layers? (Similar to what the guy from the audience pointed out earlier)

[@myhobbies5965]

Thank God, I found you Sir. And thanks to everyone who put some effort to share this golden knowledge to public.

[@MrFloppyPCB]

Best. Speach. Ever. Period!

[@Etarlam]

I contacted Altium for the other two parts of this class. Unfortunatly, only the people that visited it got access to it. Here ist the answer they mailed me (translated): "Dear Mr. XXX, I have inquired internally at Altium, well these two videos sections of #EMI Day Class# are only available to attendees who were at Altium Live. For that you would have to register in advance and only those people had received these recordings."

[@MrMartins159]

There was a lecture on Altium live by Rick called "How to Achieve Proper Grounding", seems to be same presentation, but full lenght like 2 hours, I believe it contains same info which were excluded, cause here the part about ground started around middle so 1hour on that presentation.

[@wileecoyoti]

This is an incredible lecture. Here I am paused at 1:20:40, just getting that "ah hah" of a lifetime. Thank you, thank you, thank you.

[@fe1662]

Great presentation. However, the rest of is missing and I couldn't find them. Would you please upload them as well?

[@reedreamer9518]

Yes - I too would very much like to hear the rest of the lecture.

[@AdamWright88]

same! anyone with the link to the next part of the lecture?

[@direvosabostien3565]

Here from Veritasium’s video released today, my kinda stuff!

[@SoloRenegade]

chassis ground is a reference, just like any other ground reference, and no not all chassis grounds are even remotely close to being a faraday cage. it is a path for energy to go in the event of a short, and is usually connected back to ground somewhere.

[@cvillf4694]

Thank you Rick! Awesome information

[@frankbose544]

mr hartly we electronics people would love if you made your own youtube channel to discuss all your vast pcb emi greatness

[@alexanderquilty5705]

Wouldn't that be the dream? Lol I wish I could just absorb all of his pcb knowledge.

[@Ashishchabha]

Where is full series? All the topics shown at beginning are not covered in this lecture. Please share link to full series, if available.

[@edmunns8825]

The Fourier series is important here.

[@snorman1911]

I'm a software dev and find this fascinating.

[@mangemannenn]

Shouldn't the integral at 1:20:00 be int(E*dl), where dl is a infinitesimally small distance? That is how it is written in Maxwells equations.

[@antonmilosevic]

he made a few mistakes there :)

[@Dazza_Doo]

The formula maybe wrong, the information is correct. Did you see that the world is now upside down, because many of us Non-EE have no idea, that Voltage doesn't really exist. If you can understand Maxwell's equations, then this video is probably Not for you, in regards to new information.

[@orientaldagger6920]

@@Dazza_Doo Everything can be abstracted into something. You can argue that E fields are gradients of a scalar potential and B fields are curls of a vector potential at a higher level since that is the only way you can relate E and B fields to relativity.

[@versystems]

Excellent first part! Congratulations. There is one answer in the comments that says there are two more parts. Please, where can we find them? The links listed are not useful.

[@danriches7328]

Assume IC manufacturers app notes are wrong until proven right, absolutely spot on! Maxim and Linear, who make great chips by the way, just don't help enough in this regard. Especially when it comes to dc to dc converters. Head, this is wall, approach with speed at a frequency of 1Hz and repeat... Thanks for a great video and many thanks to Rick, I've learnt tons from just a few of your presentations!!

[@orientaldagger6920]

I agree. This is from TI regarding one of their switching regulator battery chargers: Route analog ground separately from power ground and use a single ground connection to tie charger power ground to charger analog ground. Just beneath the IC use analog ground copper pour but avoid power pins to reduce inductive and capacitive noise coupling. Use the thermal pad as a single ground connection point to connect analog ground and power ground together, or use a 0-Ω resistor to tie analog ground to power ground. A star-connection under the thermal pad is highly recommended.

[@nameredacted1242]

If you see only four ground pins per a 176-TQFP IC package, THERE IS NOTHING YOU NEED TO ASSUME. IT PLAINLY WILL PERFORM POORLY.

it actually blows my mind off in terms of the EM stuff，but where is the rest ？

[@zynthos9]

Why does a die shrink make rise time faster?

[@wojciechjaworski602]

with the same circuit shrinking a die are done by choosing the newest process in which the transistors can be made smaller. Smaller transistor has a small gate capacitance so it can be charge much faster than the transistors in older process. Faster charging leads to a faster rise time.

[@alirostami9447]

great, but where is the other parts :(

[@NetlistPCB]

"Wish the school taught noise problems ...". I learned as I finished college that the job of my engineering school was NOT to teach engineering. The job of the school was to teach me HOW TO LEARN how to be an engineer. Rick, your talk here proves that the school was successful. Thanks for the education you are giving us. :o)

[@alirezazare6245]

Very good. But I did not find name of the book he introduced at the beginning of the session. anyone can help me?
