  • Thank you for teaching us. This is a nice set of considerations. I do want to make one clarification. From your repeated comments, some folks that are new to PCB design might get the impression that traces can not be too wide, meaning the wider the better. This is not correct. The issue is that wider traces contribute to the propagation and reception of noise. Therefore, traces should only be wide enough to carry the current load and no wider. I hope that helps.

  • Hey Phil, Nice video! If you find time, can you please make a part 2 where you show how to make a PCB panel for high quantity manufacturing and how that affects the gerbers and pick and place files. Thanks, KD

  • Thanks. FWIW, 0603 (5%/1%) are the smallest resistors where you can routinely get value markings on the parts, not just on the reel. Not such a big deal for digital-only PCBs but really helps in inspecting mixed-signal and analog PCBs.

  • My pet hate is large PCB space and tiny SMD parts can just push the costs up for no reson. Plus it was always good to see components flying off during a resonance search tests when we moved over from TPH to SMD. Amazing to see how much a PCB can bend at resonance. Great Vid, reminds me of my old working days.

    • Yeah, these days you either have to design 'in the moment' with what is currently available, or stockpile... Both not great options unfortunately :/

  • Do you usually modify the paste layers when ordering a stencil? I usually just let JLCPCB decide paste apertures and such, but I'm curious if that's the best approach

  • Nice video Phil! I'd be interested in hearing your position on component reference ids (R15, C3, U5 and so on). I notice that you seem to have omitted them on the Little Brain board.

    @Graham_Wideman@Graham_Wideman2 жыл бұрын

    • Thank you, Graham! For first iterations of complicated designs, I'll typically leave them on for debugging/testing purposes. But once I'm fairly confident in my design, I'll remove them - as I think it just makes the board look nicer.

  • Thanks for video! Questions.. How to calculate track length for SDIO? Are there any built-in tools in KiCad or Altium? And since we're talking about timings and high frequencies, how to wire (track length, distance between conductors etс) SDRAM memory? Are you planning tutorials in the future? Thanks!

    @wdm_frwrd@wdm_frwrd2 жыл бұрын

    • The data lines for the SD-card or the SDRAM have to match eachother, in Kicad you have a tool to match the track length. Max track length is not that critical as the speed ain’t that high like USB3.1 speeds which have a max track length of 12cm

  • Hi Phil! Great Video ! I would add though the one thing that btw JLCPCB keeps asking: a visible marking for the orientation of some of the components (chips- pin 1, diode, Cp (polarization) etc. And they aren't the only ones. PCB Assembly, no matter how well is is automatized, has still a lot of "human" steps, and we need to make the readablility of our board in the DFM process as clear as possible. That reduced the error rate greatly (pad component rotation, etc) - as there are to "standard rotation angles and centroid positions " for components - *EACH* PCB Manufacturer has different ones!
