Closed Pdada1 closed 8 months ago

Pdada1 commented 1 year ago

DAQ-Patch Panel to connect various sensors to DAQ system. Contains the schematic for 1 complete sensor system, which will be duplicated for 3 total sensors per board Sensor Ports 1-Power 2-Data 1 3-Data 2 4-Ground or Alternate Power

Schematic contains 50mA fuse for power port and RC low pass filter for data lines with a cutoff frequency or approx 20khz

5. Why there's a terminal block in the "Library"?

It's because the terminal block standard library doesn't have a 6 pin screw terminal so that's the one I made using the pheonix datasheet

Otherwise LGTM

And honestly this might be a better layout since we want to pack these in pretty tightly: image

Looking pretty good...

  1. Some silkscreens are no on the board image

  2. The 5V is not connected image

  3. Silkscreens should not overlap with vias, it will distort the text image

  4. Try to avoid long traces running side by side like this. Good rule of thumb is to space have them 3x their width apart. image

  5. I would move the copper fill to the outside of the board like this image

  6. Is this a random silkscreen on the back? image

  7. Try to avoid 90 degrees intersections image

  8. Can't have a board without the rocketry logo and your name :)

That's all for me!

Looks pretty good, just found a few minor things

  1. Good practice for traces to be centered on pads/holes afaik image
  2. Also there's a few instances of daisy-chaining where you're going trace -> hole -> trace - pretty sure it's better not to? Also this should be pretty quick to fix if it is an issue to begin with :) image
  3. Very minor but this could probably be neater? image
  4. Similarly minor but this trace is the exact same running on both sides? (the +5V one) image

LGTM! Just reporting a few errors from the DRC

  1. Seems to be a missing connection here?? image

  2. AHHH Clearance violation image

  3. Not sure if you had some specific design intent about this next part so feel free to correct me, but I feel like these resistors and capacitors around these through holes look a bit cramped, since there's a ton of free space above them. Also moving the resistors them upwards gives them better access to the ground pour (e.g. see the image below) image image
