Thanks! It looks like a lot of them have an associated circuit track and they are placed where they are needed and not according to any kind of greater pattern

Thanks! It looks like a lot of them have an associated circuit track and they are placed where they are needed and not according to any kind of greater pattern, which makes sense. However, lots of others are placed regularly around the edges of curved surfaces. Are they “via fences”, to block electromagnetic interference? https://en.m.wikipedia.org/wiki/Via_fence https://en.m.wikipedia.org/wiki/Via_fence

Could be! Sorry, I'm not an expert and I have not looked at the schematics... EDIT: On further inspection, they look like they are "stitching" two copper pours together, presumably ground or power, in order to decrease impedance maybe.

  It could be this, mentioned in the schematic: “Spark Gaps - Case: Since the case has gaps in it we expect [electrostatic discharge] to worm it’s way in via creepage and perhaps other ways. To protect the board from this eventuality, we place spark gaps along the edges.” https://github.com/ploopyco/mouse/blob/master/hardware/Electronics/Schematics/Base-R1_003.pdf https://github.com/ploopyco/mouse/blob/master/hardware/Elect... So technically a via fence, but not quite as sophisticated.
