> Also note that I only used the small trace size to get to the pads, where it's actually necessary: as any trace that is close to the limits of the board houses capabilities has a chance of not being manufactured correctly, I tried using as little trace length that is minimum-width as possible.

I wish we could stop repeating this fallacy. It simply isn’t true. You can specify 100% e-testing if you are that concerned.

I’ve had thousands of prototypes PCBs made, and only two failures I can remember, both were from under etching. Never had a NC on a trace running at specified capability.
