  1. Closed: Re: Prevent short-circuit design rule in Altium when drilled hole goes through a pad

    Well i tried using a board cutout instead of the NPH but DRC will still give short-circuit warning.

  2. Closed: Re: Prevent short-circuit design rule in Altium when drilled hole goes through a pad

    Yes i thought it was clear enough to understand from the photo i posted.



    Maybe the only solution is indeed to selectively tell DRC manually to ignore specific violations, so that it still...
  3. Closed: Re: Prevent short-circuit design rule in Altium when drilled hole goes through a pad

    No. I have a footprint of one component that has multiple fixed placement locations. However a few of those overlap which each other in close distance. Then the hole inside the footprint might...
  4. Closed: Prevent short-circuit design rule in Altium when drilled hole goes through a pad

    How can i prevent the rule from triggering without selecting "allow short-circuits" (i am assuming this is essentially the same as disabling the rule), and still keep the hole from generating in the...
  5. Closed: Re: First attempt at USB differential pair routing on a 2 layer board. Acceptable or

    Yeah sure i understand this. However i do not have the experience to tell which variables are more sensitive and/or more effective to the design.
  6. Closed: Re: First attempt at USB differential pair routing on a 2 layer board. Acceptable or

    Well....then. So technically if this was a 4-layer board and the 2 inner layers were ground layers, and assuming track width and gap was correct, my routing would work? Except the one close to the...
  7. Closed: First attempt at USB differential pair routing on a 2 layer board. Acceptable or not?

    I am making a custom keyboard with an integrated usb hub and 2 input/upstream usb type-c ports (selectable).

    So my first prototype board had some issues with usb connectivity due to me not...
  8. Closed: Re: USB2514B usb hub controller schematic basic questions

    First page it says:
    • Onboard 24 MHz crystal driver or external 24 MHz clock input

    Unless by onboard they mean on the pcb not internal;p
  9. Closed: Re: USB2514B usb hub controller schematic basic questions

    Yes the datasheet is not clear but in the reset section it states:
    "The hub experiences the following two resets:
    • Hardware reset via the RESET_N pin
    • USB bus reset"

    So technically power-on...
  10. Closed: USB2514B usb hub controller schematic basic questions

    So i am changing the usb hub controller in my project to a Microchip USB2514B since it was the 2nd cheapest on Farnell that fits my requirements and has great extra features i might want to implement...
  11. Closed: Re: EMI on data lines causing USB hub controller IC problems?

    Yes i'm not used to but i am learning. I am now designing the next prototype, it will be a couple of days before i finish. I want to keep the pcb as compact as possible, i might need to go to a 4...
  12. Closed: Re: EMI on data lines causing USB hub controller IC problems?

    yeah i removed it for readability. I'll redesign the pcb though so not much point on reviewing this one. Now regarding automatic input switch, should i just use logic gates for example?

    edit: This...
  13. Closed: Re: EMI on data lines causing USB hub controller IC problems?

    I run a ground plane on one side of the pcb, vcc on the other side.
  14. Closed: Re: EMI on data lines causing USB hub controller IC problems?

    yes sure, i can do that, run them parallel, length matched, on the same layer without any vias. However that's not what is causing the issue. The issue is caused because i run 2 set of tracks...
  15. Closed: Re: EMI on data lines causing USB hub controller IC problems?

    Well i didn't, i thought it was pretty robust to handle it through my testing with other devices like the teensy 3.2



    Sure but i can't afford to go to a 4-layer board. I can re-route to get...
  16. Closed: EMI on data lines causing USB hub controller IC problems?

    Hello. To cut this story short, after spending a full day trying to find the cause of the issue i will try not to bother you with many details.

    I've designed a PCB prototype for a diy computer...
  17. Closed: Re: Any way to make a rounded rectangle non-plated hole in Altium?

    well i dove deeper and indeed there is a way: You go to the footprint editor and you place a polygon poor cutout, and then set it to board cutout. If you use shift+space you can change drawing modes...
  18. Closed: Re: Any way to make a rounded rectangle non-plated hole in Altium?

    Yes i know the limitations of the pcb house, they are just gonna route the pcb to the desired cutout. But i can't draw it:/ Board cutout only allows for a polygon to be drawn..no arcs

    ok i think i...
  19. Closed: Any way to make a rounded rectangle non-plated hole in Altium?

    Well Altium has the option to make a pad rounded rectangle but for multi-layer it removes that option and only allows for a slot meaning the sides will always be a semi-circle and i require tighter...
  20. Closed: Re: Problem integrating through-hole and smd component footprint together in Altium

    Well i have another problem now..altium routes in between the footprint because it doesn't know there is a trace there...how do i prevent this?

    - - - Updated - - -

    Actually now i went back to...
  21. Closed: Re: Problem integrating through-hole and smd component footprint together in Altium

    In this case this was easier for me since i'm not experienced enough to use that. I actually just got it to work properly, i had to delete the pads and make identical ones with place solid region and...
  22. Closed: Problem integrating through-hole and smd component footprint together in Altium

    Hello. I making a pcb which has 1n4148 diodes in it. I want the final pcb to have both the option for through-hole and smd (sod-123). So i combined both footprints together, deleted the 2 extra...
  23. Closed: Re: Any way to auto-wire schematic from a text/table file?

    haha the whole point was not to do all the work myself :p
  24. Closed: Re: Any way to auto-wire schematic from a text/table file?

    Well i don't know..i will look into it. It's just i'll need an A0 to fit all these and then wire them without mistake. I think i'm just gonna use ports and rename them instead.
  25. Closed: Any way to auto-wire schematic from a text/table file?

    Hello i'm new to using Altium, and i am designing a keyboard. I have over 100 switches with rgb lights so 6 pads each. Is there is a way to put the components and write an excel file to say this...
