How do I route this pin on USB-C?
We had this problem on a 2 bond Flexi Rigid, my initial thought was to remove unused pads on inner layers and sneak a 100um trace between but our Fab house would class this a R&amp;D as the annulus was too tight 0.4mm finished plated hole drilled at 0.5mm (Plated hole to track 100um/4 thou and annular ring of only 75um /3 thou) will almost certainly reduce yields &amp; possibly end in 100% scrap
Our Solution:

Short together B3 and B5 on inner layer, then only use USBC, USBA and USBC 2.0 for data transfer. These cables don't wire up pins B10,B11,A2,A3,A11,A10,B2,B3.
