STM32 PCB Design - Complete Walkthrough - Altium Designer & JLCPCB - Phil's Lab #41

[@garysmith8089]

Good on You Sir! This STM32 Tutorial is a Doctorate Course on ENGINEERING of the real-life PCB DESIGN process and should be awarded as such! I have spent literally 100s of Hours doing a re-spin up of my past 30 years as a PCB Design Consultant. One can experience a wide range of competence on KZbin! Yours is at a Level FEW of your peers provide. Again, Good on You and Keep up the Great work Professor Phil!

[@jestho3503]

Again, a really good video Phil! Thank you. I´ve been using Altium for 11 years and I always get useful tips watching your work. One thing that came in to my mind when using small resistors and capacitors like 0402. Keep the connected copper to them as unified as you can. We have had problems in the solder oven with components standing up towards the side with the largest copper connection. Several times I have had to decrease the conductor width towards groundplanes to avoid this.

[@wesleybecker834]

Yes, tombstoning is the name of the phenomenon. Thermal relief on the pads becomes very necessary for these small passives.

[@mwanikmurray537]

If someone is wondering why sometimes you can't copy and paste MPN (Manufacturer Part Number) from JLCPCB altium, it because of the while spaces at the beginning of the MPN. You need to remove the white/blank spaces first. I am not sure this is clear but yeah, you need to remove the white space at the beginning.

[@grndplane]

Great video, one comment, keep GND names turned on. Sometimes when circuits are copied these names can change to something else, like GND1 or whatever the software decides to name them. If they are turned off you will not know that they have changed and may not be connected.

[@eyupkayatuzi4444]

Hi, you connected boot0 to ground because you said i will just be using swd. My question is; if we do that, can we program to our mcu via usb port?

[@PhilsLab]

You would have to write a custom USB bootloader to be able to reprogram the MCU. Otherwise, make a provision for pulling BOOT0 high.

[@luiscortina9920]

Why connect the USB data lines if you're going to program using SWD?

[@useromer]

[@duduc998]

Could you find it? I had the same problem.

[@crosswick]

Isn't Altium still prohibitively expensive? Please correct me if I'm wrong

[@artrock8175]

Pretty sure it is. What good is a free trial if you can't afford it after 30 days? But it's obvious why Altium would want to sponsor KZbinrs who've used KiCAD for many of the tutorials as it clearly cuts into their bottom line given the cost. Which starts "poisoning the well" of content most of us enjoyed before money hungry, corporate entities shut things down. I started watching this channel because of KiCAD...

[@Luke_Ainsworth]

Great walk through mate. Any chance you could do some tutorials on writing code and uploading it to the controller?

[@PhilsLab]

Thanks, Luke - I actually have some programming tutorials on my channel.

[@ahmadelkontar]

Can we also add polygon pours for ground on the signal layers ?

[@persupersulast2506]

is double sided pcb where bottom is digital and top is analog good idea? 4 layers, top 12v, bottom 5v and 3.3v and middle layers both ground?

[@優さん-n7m]

Talking about ferrite bead, isn't it that this component shall create large sharp peaks in the PDN impedance and thus is bad?

[@robertmotion]

Great video. Question. I'm replacing my ebike motor pcb. My original pcb has 5V GND SP H1 H2 and H3 components that's I'm familiar with and know how to connect. My replacement pcb has these connections PLUS a "K" (relay?) and "-" beside it. What is relay used for? Does K mean relay? And, since "K" is not a component on my original pcb does that mean this pcb will not work unless connected to some type relay? Tried looking online/Google. No luck. Need some help. Hope u can. /bklyn 👑

[@mattcarberry1913]

Thanks so much for making all these tutorial videos that shows entire process from start to finish with the rationale for the decisions made. I have a couple questions about impedance controlled traces between your designs in the videos and in the GitHub repositories. In the video you set up the USB trace widths for the JLC7628 stackup (0.26mm), but the gerbers in the GitHub appear to show them at 0.1532mm. Did you end up changing to producing this in the JLC3313 stackup after the video was finished? I'd like to get some boards produced and just wanted to make sure I have this correct. I see a similar-ish thing with the previous LIttleBrain board, where in the GitHub history the USB trace widths were originally 0.2611 mm, but when you did a revision to remove the USBLC6-2SC6, the trace widths went to 0.2mm. Was that just a simplification and this level of detail doesn't matter at such short trace lengths? Thanks again for all the fantastic videos.

[@LOGICOMA]

Absolutely awesome! So helpful!

[@PhilsLab]

Thank you, Mick!

[@valentingomez4546]

Phil just a quick question, at the time of flashing code to the MCU, does it have to be done via an STlink or can it be done via the USB connector on the board?

[@KevinStoriesTV]

After placing stitching vias, do you need to repour your L2 L3 GND copper polygon?

[@hemanthdevaraj1991]

Hello, good content and easy explanation, here you have provision of 4 layers, yet you used only top and bottom layer, you could have gone for just two layers

[@djordjeen8137]

I can't make a difference between first generated gerber file and second generated gerber file, stiching vias are not shown in internal (GND) layers???

[@direncsertac2562]

Great video. Your videos about pcb design assist to us. I have a question about stack up section. When you adjust the layers of the pcb, you selected in the power and ground layer as signal instead of plane. In this video you mentioned that this choices avoid creating a negative gerber. Does this choices make sense? The senior employees who work in our company always prefer the plane. I'm confused as a junior hardware engineer. Regards.

[@PhilsLab]

Thanks. I guess it's more of a preference/habit thing - there's no harm in using either.

[@colinm6672]

Hi Phil - Excellent video. Can youb please remember to provide a pointer to altium footprint library. thanks

[@優さん-n7m]

In the PCB stack, you entered the value for Dk but not Df. Why is that?

[@alexanderquilty5705]

Why did you not seperate VREF+ (Called VDDA in KiCAD STM32 Video) to 2 different 3.3 Voltages, one Analog and one your common +3.3V? Edit: I wonder if he ended up using a different STM32 board, and that is probably why.

[@noealves8400]

Amazing video! and so forth :-)

[@PhilsLab]

Thanks! :)

[@behnammadadnia3410]

That was a great tutorial, thank you very much. (I wanted to use the Altium lib that you uploaded on Git, it seems it does have all the footprints (just a limited numbers), but it has many more schematic symbols. So, maybe, would you please upload it again?)

[@armincal9834]

Isn't each individual VDD pin supposed to be connected to the ground through a capacitor? Then how come we put 5 parallel caps and connect all vdd pins to each other and then connect them between + and -? Doesn't the behaviour change? In other words instead of connecting each pin to a 100 pf cap we are connecting all of them to an equivalent 500 pf cap(parallel caps add up)

[@aliitastan]

Thanks for the video. Just a quick question, I don't have GND vias placed under the chip on my footprint taken from STM website. Should I place them manually?

[@PhilsLab]

If there's an exposed pad (EP), then yes - both for electrical and thermal reasons. Some STM32s in a QFN package come without an EP however.

[@aliitastan]

​@@PhilsLab Yes, there is an exposed pad which is connected to ground through pin 49 on STM32WB15CC. I am designing a board which will be working with Bluetooth. I am using 4 layer board with a composition of Signal Ground Ground Signal respectively. I placed smaller vias (0.5mm diameter / 0.25mm hole size) on the center of splitted solder pastes (It came separated as 16 square pieces). Then I placed a polygon connecting them to GND together with decoupling capacitors on the bottom layer. I also used a thermal relief style vias as you mentioned. These are great tips which I learned from you, this is my first PCB design for manufacturing and I will be very happy if it works as intended. Thanks for your time!

[@Fleurlean4]

@@aliitastan Did it work?

[@erent.7210]

that is an amazing video to practice, thx to philip. I can't find the library. Can you help me to find it?

[@KevinStoriesTV]

For your personal projects, do you create your own symbol/footprint before starting the schematic design or settle on what the manufacturer part search offers?

[@sinamokhtari9859]

Thanks for great video. Where can I find the altium footprint library you used in this tutorial?

[@TheNeukyhm]

Hi Phil, at 24:12, the first result is an oscillator, which correct me if I'm wrong but it needs just power and you have the clock output. Wouldn't be that more desirable than a crystal?
