I notice that north of the long east-west transmission line, at the northern keepout boundary on layer 6, there are a couple of vias that have almost complete ground shield between the vias and the HDMI TX2 pair.
Question: What is the fill polygon width for ground fill on layer 6?
I can see two fairly simple solutions to complete the ground shield around these vias:
- Add traces to complete the ground shield between vias and HDMI
differential pair. 2. Adjust trace/fill polygon width for ground fill on layer 6 till the ground shield is complete.
I'll sleep on it and take another look tomorrow morning.
Looks like you already addressed this in the latest gerbers! Any chance we could use another trace to even up the little dimples that are left in the edge facing the differential pairs?
I glanced at parts of the rest of the board but it would be much more straightforward with the schematics. Do you have a way to compare changes with previous versions of the board to see if PADS did anything surprising behind your back?
