So Altium can generate IPC-2581 but not view the output? Great😅 #halfbaked

Looks like a cool way to place a diode?

Dear zack, a 250 to 900 v input and 24, 18 V and 12 V multi output flyback gas been designed for powering up a pwm unit followed by auxiliary power needs. Switching frequency is 80 KhZ. For these extreme step down conversion ratio some times the switch is getting damaged, though it is equipped with RCD-R snubber. Any suggestion from your side to troubleshoot this concern.

Is the default 2500 value for polygon island removal a good?

hi @Zachariah-Peterson i see in some designs that they make a chassis using 1KV or higher capacitor with 1MΩ resistor connected to the main ground is that correct way for that?

Reminds of the type of people that were more common in silicon valley about. a calendar decade ago...before mba and india locusts downgraded the historical bright-eyed giddy engineers scene there.

I believe the last pads at the end are a style of Net Ties.

They are called solder bridges, not stylistic 😅

the peculiar pads for that "component" are jumper pads, with the triangle shape designating a normally open pad

"Fill and cap feature on Altium" very good tips thanks

audio volume is very low

Thank you Altium Academy :)

Ferrite filters are used for noise reduction in signal lines, because they can cancel out common noise which is impossible for all of the above mentioned. In some cases you don't need to filter out DC spikes and I was wondering how you will apply a filter which will attenuate a signal by 3 times. Then you will have 1.3 volts instead of 5. What was the point of those simulations?

Is there no NEC antenna simulation out there which can help designing the inverted F antenna?

Awesome video, Thank you.

High speed signal propagation - advanced black magic

Altium should support KiCAD's built-in schematics and footprint libraries. They are literally perfect and is such a time saver. The standard libraries that used to come with altium is now only available when you activating and linking a 365 Workspace, which just makes me wanna cuss!

Why can I not simply move items from the part search into my library and edit the existing files Altium provides. Why must I down load or use the cloud system to do what I believe to be a simple application

Hi Zach, Thanks for the nice video. Just a question, if I may...let us assume an additional signal GND is needed on the secondary side, how do you deal with this? Do you use the same Y-rated CAP to connect it to earth, or do you use a net tie between itself and the secondary GND which is already connected to earth via a Y-rated CAP? Thanks for your insights!

thanks very much, is there a way to get some net list?

What style symbols do you adhere to? I have decided to use the IPC Land Pattern standards but I can't find anything about Symbols except for IEEE-315/ANSI.

Hi Zack, when talking about calculating the propagation constant. Just to clarify, you are talking about the rise/fall time frequency right, not a clock or signal frequency? The frequency would be about 0.35/Tr?

I am using Altium 22. After I clicked 'commit' showed at 1:47, I saw an SVN error "is not a working copy". I also tried to create a new test project and repeated the steps, however it did not work. May I know how can I solve it?

Very interesting and pertinent. Well worth the listen. Not a lot of embedded or edge discussion out there.

Greetings from Mexico, city of Acapulco... I'm just learning to use ALTIUM and I see that it is a magnificent program. Soon he will be an expert like you.

Conclusion Implementing logarithmic and optimized calculations on edge devices with limited resources can significantly improve efficiency and performance. By following these strategies, you can develop robust and efficient solutions that make the most of limited hardware capabilities.

I’m only half way through the video. But had to comment to say this is well worth a watch. Great interview, well done gentlemen. ✅

Afrojack talking style😅

I have a PCB dxf with hundreds of holes and can't get to convert it , any suggestions for a boardshape that includes many holes?

Excellent presentation 🙏🙏

for that ADC example, even with a GHz Sample rate ADC, it would still be able to capture low frequency products. So anyway we need to split AGND and DGND right?

I was using a ferrite bead pi circuit filter for a converter but was getting some issues with conductive emissions, so increased the capacitance and replaced the ferrite bead with inductor but still getting noise around 500kHz. Anyone any suggestions?

I think the parameters of the "model" of that bead is flawed. Isn't the parallel resistor a tad small and your parallel capacitance a tad high?! Looking at the LTSpice Model parameters for parts that have an inductance in the 150nH range (Würth 742792097) gives me 35 ohms and 800f as in FEMPTO farads. Nowhere near 1.5n... Also you are unlikely encounter a scenario where there is no additional capacitance like 100n decoupling near the load or somewhere towards the power source.

I just watched your video on not using ferritin beads. No comments on using those in this design?

Thanks for video! 1. Inductor has parasitic capacity, capacitor has parasitic inductance. You draw only equivalent scheme of FB... Is this not important? 2. LC-filter will be effective in high frequency when his cut off freq = 100kHz, and DC 2..3A ? it means that inductor and caps are big sizes, big parasitic.

Anyone knows a video that shows how to make things for the en of the project

Why use 10Ohm series resistor in a power filter? In the last example drawing 1A it will drop 10V...how does this make any sense?

Thank you for the nice video :) I agree that the damping of an LC filter is generally better than that of a ferrite bead filter. But a real-world inductor will also have some parasitic capacitance, which will dominate at frequencies above the self-resonance-frequency (SRF). So the AC transfer characteristic of a real-world LC filter will also be messed up at high frequencies... just like the ferrite bead. Furthermore, a real-world capacitor will also have some parasitic inductance, which will further degrade the filter's performance at high frequencies in each of the three designs. I sometimes add a ferrite bead pi-filter on the output of a DC/DC converter to provide some damping for high-frequency noise (frequencies at which the regular LC filter of the converter doesn't work due to the parasitics). All the ferrite beads I've come across have a specified bandwidth of 100MHz, not 10MHz. My intuition always was, that an inductor with a similar SRF must necessarily have a very low inductance, which results in an increased cut-off frequency of the filter compared to the ferrite bead. Thus, if I can trade off the worse damping for a lower cut-off frequency, the ferrite will do better. Your video really made me think about my past design choices and I will definitely do some more simulations in the future :)

You also have to account for series resistance and the load current. Ferrite is basically an inductor + resistor. It doens't have that resonance but you can only power so much with it. It is usually cheaper and smaller too so it still has its uses.

Can you please carry out a simulation with higher capacitor values, with at least 10µF?

So, the big question is this, why continue to manufacturer ferrite beads if they provide no benefit according to simulations. What actual use case does a ferrite bead serve?

The main difference between a ferrite bead and an inductor when used as a filter is that the ferrite bead, if chosen correctly, will convert the noise energy into heat, whereas an inductor will just cause it to slosh around until some other lossy element(s) in the circuit convert it to heat. The complicated part in the above is the "if chosen correctly". The noise energy must fall within the lossy frequency range of the bead and the bead must be modelled at the DC current it is going to run at, as the parameters change with current! As for datasheets, well we can't even get manufacturers to stop recommending parallel 10nF + 1uF (or similar) surface mount capacitors for IC decoupling, when using a single 1uF ceramic surface mount capacitor would be better (cost, size, performance) in the vast majority of cases. Good luck getting them to stop recommending the use of ferrite beads on power rails to ICs!

Can somebody put a ferrite between Altium and the stupid idea to cancel perpetual maintenance? I’m very angry.

your analysis ignores the fact that the damped LC circuit has a considerable loss at lower frequencies and lower loads due to the series resistance. you're attempting to power the load with 5V, but only 1.67V is making it to the load (in the 5ohm case) due to most of the voltage being dropped across the 10 ohm resistor. I would say the ferrite bead is still a better alternative in the examples provided as the 5V DC actually makes it fully to the load and removing the series resistance on the LC circuit re-introduces the resonant peaking.
