I have a question about one of the traces: In the layout picture it appears that something resembling a via coincides with HTX1P following the second wiggle after the trace turns NE. If it is a via, what is it doing there? If not, what is it?
you've lost me, sorry. i don't know if you have access to an image editor but an arrow pointing would help - i know you're using an iphone so that might be a leetle awwkward...
Borrowing my wife's laptop I used the bundled Paint program to scratch some marks on the image from your wiggles progress message. What I'm referring to has been in the layout pictures for a while longer than the image I used to note it and I was curious but had bigger fish to fry.
Of course, hopefully you never have need of soldering or desoldering the μHDMI connector by hand. Looks best left to the oven.

this is why we'll be doing a test run of some low-cost 2-layer PCBs (1in x 1in) just with the DC3 land pattern and some test jumpers, which will go through the oven to make sure that the DC3 actually sits down and all pins connect to their pads.
lot less risky than $USD 2,000 for complete PCBs only to find that after 5-8 weeks yet another footprint layout doesn't work.....
Good plan.
