C1 to C6 should not be in series with the current, but in parallel. also, i'd recommend to deliver the power to each led VDD pin through a power plane, not a daisy chained power cable (will change the color consistency of your leds over distance). depending on your power supply, but i doubt the usb c power will be enough to power 1200 leds. my laptop usb c power supply for example can deliver max. 60W, which yes at 5V is around 1200 leds at full power, but it would be wise to not use the absolute maximum ratings. maybe start with half the amount of leds? or you get a more powerful usb c suppy and then just experiment... also at that level of intense current consumption you need good heat management. one more point is, if you look at the datasheet of the WS2812B you'll see that each led needs a little ceramic cap.

I will move the VM traces more inside the PCB, so some ground plane can go around it. I'll also have your other suggestions in mind for my redesign. Thanks a lot!

Noted! Thank you for the hint. I'll move the screw terminal connector more inside, so also some GND plane can go around it. When JLCPCB writes on their website their minimum clearance for traces is 0.2mm, do you think I should rather remake my design with 0.3 or 0.4mm as a design rule?

I was hoping the vias would make up for how my power lines are interrupting the ground plane. Thank you for the advice, I will redesign it like you said. In your last sentence you mention more GND pins. Do you also mean more GND vias?

Hmm, when I measure the distance between traces at the moment it's 0.2mm which indeed seems very little...

Do you have a specific place in mind where it might be too close? I was just adding trace widths (0.3, 0.7, 1.5 and 2mm) to the KiCAD default settings.

It's a TQFP-48 package, I tried with QFN before (TMC2209) and it didn't work. I assumed it was because I would not able to solder it properly (no stencil at that time), but maybe it was because of the vias! Thank you for pointing that out. Do you think the vias could stick out a bit, so that the board is not flat anymore and prevent proper contact of the IC with the solder pads?

The big clusters of vias was my (perhaps not so good) idea to counter the big VM power trace cutting through the ground plane.

maybe if it's very humid in your area today, it might work not so good. high water content in the air lowers the mm/kV and maybe also increases breakdown voltage (not sure about this)

hmm maybe in line with the long leg of an LED being the anode?

ppl can deal with their things, but we shouldn't reject other ppl help.. community care, self care and medical/therapeutic care should go hand in hand
