How Denpaflux Simplifies EMC Testing

[@GoodWill-s8j]

I couldn't find any information about Mitai's pricing.

Interesting topic. One important thing missing here is io (connector) protection for over voltage events like surge, burst and esd. Zach mentiones io protection but that is not fully covered, but probably easy to implement with an AI rule.

[@Zachariah-Peterson]

That is a good point, and I agree the tool will probably be able to handle it. The tool knows when certain components are part of a switching circuit or PWM driver circuit, so I would not be surprised that it could pick out I/O protection if present in the PCB. The sample design I provided did not include any chokes, TVS diodes, or similar components you might find for I/O protection, so I think that is why nothing was brought up about it in the tool. Also I think it was not mentioned in the project description, so the system did not look into the need for I/O protection. Maybe we will have to experiment with this in another video.

I have a question regarding the ground split mentioned in the video, If you have low speed signals/high speed signals and power, as the low speed signal don't have a defined return path directly under the trace, can they get coupled with power and high speed return path and cause crosstalk? How can you fix that? If you can make a video about it it will be very helpful otherwise i am happy to discuss about it here. Thank you.

Low speed means low dI/dt and that means low inductive effects (if dI is relatively small).

[@fedimakni1200]

@robegatt what if the change is in the BLDC motor power and signal lines. As it is powered through mosfet so the di will be big and that can affect other signal if it is too noisy through the return plane correct?

[@robegatt]

@@fedimakni1200 if you have power lines crossing split planes you are actively searching for troubles emission wise...almost a jamming device.

[@fedimakni1200]

@@robegatt no i am not speaking about split planes here. It's a solid gnd plane

[@GoodWill-s8j]

​@fedimakni1200 you literally said ground split.

"Any terms and conditions of Customer are excluded, irrespective of whether reference is made to them in offers, purchase orders, order confirmations or other documents regardless of whether Company has objected or not. Any prior agreements including but not limited to confidentiality agreements concluded between the Parties shall be in its entirety replaced by this Agreement retroactively as of the execution date that agreements." I think this gives them the right to scam their customers.

[@Zachariah-Peterson]

LOL no, literally not what any of that means.

[@GoodWill-s8j]

@Zachariah-Peterson You can choose your favorite word instead of "scam." It doesn't change the situation. By the way, that was not the only scammy paragraph in their "Terms of Service."

[@Zachariah-Peterson]

@@GoodWill-s8j let me break down the legalese for you: Sentence 1: When you agree to the terms and conditions, you're only agreeing to these terms and conditions, not whatever information the customer thought they heard in offers, purchase orders, order confirmations or other documents and arbitrarily decided were also terms and conditions. Sentence 1, but even clearer: The only terms and conditions you are agreeing to are the terms and conditions in this document. Sentence 2: These terms and conditions override other agreements we already made with you. Terms and conditions are voluntary and transparent. It's literally the opposite of a scam.

[@robegatt]

@@GoodWill-s8j an agreement to change the agreement terms retroactively sounds like a BIG ass-covering strategy... 😁

[@robegatt]

This is EXACTLY like autoroute... would you buy a used car from it ? 😅

[@johnyang799]

idk it's more like DRC if I understand correctly

[@Zachariah-Peterson]

How is it like autoroute? It's not routing anything.

[@robegatt]

@@Zachariah-Peterson I mean you could use it for general macro advice but those things you wouldnt do anyway if you had a minimim experience. Like autoroute you can use it for the general layout to speed up the job, but it is something you can do without if you know what you are doing. And oftentimes these kind of algorythms cannot grasp the whole picture and the trade-offs you accept in the particular case you are working on.
