![[LIVE] How to Achieve Proper Grounding - Rick Hartley - Expert Live Training (US)](/img/n.gif)
Since graduating university I've been extremely frustrated at the slow pace and lack of learning opportunities in employment. This is gold, the stuff that companies want to drip feed over a decade, and even then it might not be right! Rick has done a great service in sharing his knowledge.
I'm electronics engineering student and the things I learnt from this video is priceless. These are the things you can not learn in university (mostly). Thank you.
most PCB Design stuff, you do not learn at university
Thank you very much Suleyman
@@RobertFeranec True, our university doesn't teach PCB design. Can you make a video why most universities around the world don't teach PCB design?
This is the new university. UA-cam university.
My advice - get a internship/student job at one of your faculties. This helped me a lot to get in touch with "the real" world problems of engineering.
thank you Rob. This is great. World needs people like you.
Thank you Bilen
Bro your video helps me to study so many things.
I hope you to be very rich Robert. But these lessons you share with us are more important than money. Thanks for everything.
Thank you Musa
Robert, your questions were right from the industry’s heart, you were a great host, please keep making more content like this..
Thank you very much Abdullah. I am very happy you liked this video.
Two of 3 people I owe my job in the defense industry to... Thank you Gentlemen
Thank you BrokenICry
More like this? YES! These are very interesting and informative. Grounding, EMI and these sorts of issues will never go away. Every new design opens all new opportunities for these issues. Hearing this stuff repeated and taught should help everyone. Thanks Robert and Rick - great stuff.
I love your recorded videos that are done interview style with industry SMEs. The way you ask them questions is helpful in enhancing the video watchers understanding on the topic. Thanks for the awesome interview!
Young engineer here, 2 years of experience with 3 of internship/apprenticeship before that. This video is beyond informational, and a fountain of knowledge. I'm going to continue with the rest of your videos, thank you!
This was the mother of all ground lessons! Amazing value delivered! Keep it up!
I was recently allowed the great privilege of attending a 1-day seminar taught by Rick Hartley at the AltiumLive Design Summit in San Diego. Those 8 hours completely changed how I viewed PCB design, and electronics as a whole.
Thank you, both of you. I learn a lot from these recorded calls. I hope to see more of them on this channel.
These kinds of videos you are creating are pure gold, thank you Robert.
This video was amazing, the channel is a gold mine for understanding advanced electronics.
Yes, I like this kind of video and these videos are absolutely helpful so please keep making great videos like this one.
Man, you don't know how valuable it is that this information is saved into public space and made available to everyone like you do and I can't thank you enough for doing this work for the greater good so to say, I wouldn't be able to learn this kind of stuff that is this specific and detailed and very easy to learn and understand so again thanks for making this available here on UA-cam. You're the best 👍❤️
That was extremely interesting. I would really love a video with Rick going over some BS found in switching mode power supplies application notes or layout guides.
Thank you Nik
I'd also be interested about that. Especially multiple grounds for power (or what they call "dirty" ground) and signal and also coupling primary/secondary ground with capacitors.
There is a PDF available on the internet on exactly that topic!
Presentation-6D - PCB Carolina
PCBC2018-6D_Rick_Switcher Layout.pdf
Good videos to hear new info. What I miss is the examples on the improvements which are made against the switcher manufactures application notes. It will be a good lesson to see the details on how de placement and routing was, And how Rick improved this.
Beside EMI improvement, what was the improvement on functional behaviour of those DCDC switchers? An important item beside EMI, is a stable reference point.
That meets exactly what I was preaching to my customers, but it is very hard to convince digital designers fearing the analog world to understand the concept of ground return paths. (I am an apps engineer for power delivery :-)
Hi Robert, your idea of interviewing experts, like in this video, is excellent! It helps confirming some already known facts, and also shines some light on some new problems that we have with hardware design. Keep going, I love your content! 🙂
Thank you very much wingunder
i remember you robert before remembering what is impedance, and now you are working on understanding this . Thanks to this effort you re having good guests like Hartley and we all learn new things together.
Robert, the format these YT posts of you is superb - so please keep doing this. I also highly value you adding additional info. It also helped a lot for me to have Rick's excellent slides for visualizing the issues.
Thank you very much Frank
Finally found the time to watch this. This is fantastic information. Again, thanks for the time and effort you put into these videos!
Absolutely GREAT Video! I really dig the "conversation between two experts"-format. Rich dropped knowledge left and right while you kept asking great questions.
Many instructional videos on here kinda feel like drawn-out lectures. THIS did not feel like an hour at all. i really enjoyed myself and I am now a better engineer than an hour ago. Thank you!
You are the best with the guests you bring in the show!
Do I like the kind of video's where you discuss topics with different people?
Yes!
Great video ! Your question are always on point, and Rick's explanations are put in a way that makes them so easy to understand, almost "obvious". Thank you so much !
Thank you very much drumn incolor
This kind of videos are great! I remember back in 2008 when we have a consultant that taught us a lot desmitifying these kind of subjects.
Very interesting, useful and relevant information for me. For a long time, I recommend your channel to all my friends and colleagues. Thank you very much.
This is pure gold! Must watch for anyone in EE! This will save you ours in the EMC lab and thousands of dollars.
Wish I watched this video 15 years ago. Could have saved me a lot of sleepness nights, frustration and money. Thanks Robert and Rick, true legends...
One of the best videos about this topic . Well done Robert!
Extremely interesting video Robert!
There are no words to describe Rick Hartley... He is just amazing!!!
Bursted all my myths regarding analog and digital ground.
Rob i will remember this video through whole of my career.
Best video I have seen in a while. With a great speaker!
Super fascinating Video ! Thank you Rick Hartley and Robert Feranec.
I love this video. I've now watched it multiple times! I want it engrained in my head!
I think this will be the best video in all of 2021.
Can't remember how many times and how many people just don't or won't get this concept.
School of hard knocks, as it were.
Best wishes, safety and healthy to both of you. Thank you.
Thank you very much
Hey Robert. I found your channel 2 days ago. I am an RF engineer and try to design some high-speed PCBs, your channel is great. Thank you, you help me a lot.
I’d like to see a video discussing grounding around connectors more. You see terminations around connectors that separate the connector ground from the PCB ground all the time for ESD or EMI reasons. You see 4n7 caps paralleled with 1Meg resistors. Sometimes you’ll see ferrite beads in the signal ground path and in the power path. This can help with emi but can hurt esd. A lot of times you end up with connectors or chassis that you cannot tie the connector shield to anything. Especially with hdmi, usb, Ethernet.
Yeah, I saw so many different opinions about this but not one single / true / correct answer... It would be REALLY nice to know what to do best, what to do if best cannot be done and what NOT to do :D
Thanks to both of you, For sharing your knowledge and experience.
Thank you very much Hussein
Thank you Robert, I enjoy watching your videos. Great stuff.
Fantastic Robert..plz continue these marvelous series in future.
Perfect video Robert! Rick is a guru on EMI. Keep up the great job! Thanks!
This is mind blowing Rob! Hope to see more of this kind. Thank you for sharing.
Thank you very much Edgar for watching
Robert, this video is a great portion of knowledge and is served in thw best way that I ever dreamt. I hope, that such videos will be uploaded periodically on Your chanel.
So, I have to see rest of your videos.
Love that you keep addressing the topics I talked about some time ago. Thank you Rob!
These recorded calls are excellent to learn!
Very helpful and valuable information! Exactly what I’m doing right now is the emi and proper grounding.
Great video. It confirmed some of my paradigms on EMC, broke a couple of my paradigms and I learned a few things as well! Great guest too!
Great info Robert, it was very technical, it demystified a lot of difficult concepts, and Rick is just precise and very clear with his comments. Switching power supplies layout from EMI point of view and Shielding of cable were really explained well. Please continue this kind of videos, it was one of the best videos.
Thank you very much Chethan
Dear Robert!
It's good format and amazing topic, thanks to you and Mr. Rick!
One of my first serious boards was single phase power meter with ground common live wire, shunt in live and current transformer in neutral, capacitor divider plus dc/dc in power supply, high bit ADC.... It took me 6 iterations of the board to pass 1.2/50 us 6kV tests. After all, it was amazing practice, that costed me few gray hairs.
These are usually the only types of videos I watch
I do enjoy your discussions with experts who share the experiences in solving different problems
Thank you very much Doug
So this clears a question pretty much once and for all. Thanks so much guys!
These videos are the best resources that can help the daily work in these EMI years!!
Thank you Luca
Mr. Hartley's video on the Altium page changed my whole perspective for wattage flow in a PCB. Thank you, Mr. Feranec for these kinds of videos. Really informative.
Thank you Sakib
Every talk with Rick is so precious!
Thank you so much, Robert!
Maybe more details about USB connection, this always causes me some trouble.
Thank you very much Zhitai
Thanks for the information with detail explanation, Robert and Rick have done a great job which helps many many people. The grounding issue has been the most critical issue in every PCB layout. Many app notes tell the engineers to split the ground planes and many troubles come from it.
Worse yet, I have had people tell me that you DON'T EVEN split the ground for the "classical" ADC example, that it is one ground, and digital one at that, even on the analog side of the chip!!!
Thank you so much Robert. As mentioned by others, its a privilege to listen to you and Rick Hartley. I would highly recommend everyone to watch other talks from Rick as they are gold mines of information. I have only designed few pcbs and the first one i did was a redesign of an existing board and voila I found the dear old split plane. As mentioned by Rick, Prof. Todd Hubing from univeristy of Missouri is also an expert in design for compliance. Possibly an idea for a future call.
Thank you very much Jayakrishnan PS: I placed Prof. Todd Hubbing on my list of possible future talks
junior engineer here, what a masterpiece, those calls with rick! thank you and thank rick!
Thank you very much for these kind of videos, they are really useful, this is the best channel for PCB designers
Thank you very much Cesar for nice words.
An engineer cannot benefit more from those talks with all the valuable experiences. thx!
I learnt a lot of thing about this topic as an electronics engineering ! Thank you Robert and thank you Rick.
i absolutely like these kind of video, I highly like this and the one with Eric.Thanks both
Thank you very much manojkumar
I really do like these types of videos!
Thanks for posting!
Great Video - it raised quite some "hmm, I think I'll might have to think of that again!" because there were quite some aspects I did not have on my radar. THANK YOU to both, to Rick Hartley and you, Robert, for raising such highly important (and I think interesting!) aspects that I feel are widely ignored or are prown to common problems. THX a lot, love videos like that.
This video is gold for emi and power supply design.
Thank you Robert. I am in the process of designing a PCB and decided to watch this video, oh boy do I have a lot to think about. So many of the concepts that I have picked up over the years have been challenged. Having designed RF circuits in the past, I was fooled into thinking that I knew how to design for EMI. The RF designs I made were for hand held battery based products. Now that I am doing switch mode power supply design, I have realized I have a lot to learn - Thanks again
Great video...Rick is one of my favourite persons...I learnt what exactly differential lines mean from his webinar at Altium Live....Thanks for the video robert..!!
Thank you Gudimetla
Thank you for this. Please do more!!!
خیلی خیلی ممنون بابت این اطلاعات مفید
Thank you very much for this useful information
and I follow you from Iran
The best lesson ever got. That's amazing who much I could learn from this. Thank you!
Thank you very much Jacek
Excellent Video, I really enjoy to watch it, many thanks Rob and Rick !
Great idea with this kind of videos, it allows us to meet many specialists and see diferent points of views :) looking forward another lesson!
Thank you very much Mateusz
These discussions are very interesting.
Thank you very much. I am a visual artist and a ham operator. My basic knowlege is low and this sort of video gets me closer to solving problems well. Slowly I am learning to understand them.
robert, thank you a lot for your videos, they are all great and very helpfull !! please keep it up!! best greatings from austria!!
Thanks for the video Robert. It's amazing how Rick answer perfectly to every questions. Thanks for making this a reality Robert.
Thank you very much Adarsh
Extremely excited for this video. Rick's talks have fundamentally changed the way I design PCBs and think about the flow of energy in circuits.
Wow, this turned out to be extremely relevant to me, since I'm currently working on a design that runs four unidirectional RS-485 signal pairs over cat5e or cat6a cables. I've been thinking about whether to go with shielded or unshielded cables, what to connect the shields to (and where), whether or not plastic enclosures were going to be a problem, and how to ground everything. This video answered all of those questions for me!
Thank you very much Graham
I like this kind of discussion very much!
Great Video, thanks for sharing! I'd love to see more of this kind!
Thank you and rick for this perfect video. your practical questions was very useful. please share more videos like this.
We can't thank you enough for these videos!!!
I work with electronics since I born, but still these videos clear sooooo many of the confusion gathered through the decades in many rule of thumb or "do this way" kind of instructions where it is very well possible that the author also didn't know exactly what happening or why, just spread the (mis)information.
The most well known example is where to tie the shield of the cable. I never thought that the shild AND the chassis at both ends should form a Faraday cage!!! But it is so self-explanatory now that it is a shame I didn't realized that until now! 🤦🏻♂️
Thanks a lot for providing this video with full of information for designers as me facing such issues always
Video was amazing. Please do more of these
Robert and Rick together - that's awesome!
I have purchased all of Rob's courses (which are amazing) but these one-offs that he creates are just outstanding. Rob... take it from another Rob..."you are the man." Well, you and Rick. I'm working on an EMI and noise problem right now. As another viewer noted. This is gold.
Thank you very much Robert
very great man, this video answered many questions i had for a long time. thank you
THAT' S VERY VERY GOOD.
THIS IS SPECTACULAR !
THIS IS GREAT !
Please Continue these videos
Loved the video, already learned so much. Also remembered mistakes I made in the past! Thank you Robert.
Thank you Daniel
Great material. It answers my million $ question of how to connect the Shield layer of a cable and understand connecting the Chassis to earther ground is not important. Thank you!
that's video is soo amazing. please continuous it
That's a great video. I should saw this video a few years ago. I had some problems that I think this video could solve them.
Thank you Robert
Wow! This is pure gold! Thank you!! I thought I was the only one thinking USB is shit, I had huge problems in the past with currents flowing through the shield and all sorts of ESD problems because of that. More from Rick please!!!
Awesome, this is classic !
Thank you Robert.
Wonderful Interview!
Lots of problems are solved for me!
Such brilliant minds, Thank you Robert!
Always learn new stuff you your talks. Knowledge money can't buy, only the years of experience you guys have 😍
that was a grate video on shielding and grounding, keep this type of videos going!
I like to watch your videos, they are informative and useful specially on my job. Thank you very much !
Yeah, loved this format !....more please !...cheers.
Thank you so much for sharing such a great video conversion. It benefits me a lot.
