I have laid out this board that includes (among other lower speed connections) a 1 upstream and 2 downstream ports on a 0.5mm FR4. The USB differential traces are 0.6mm wide with 0.15mm spacing between them. Can you give your opinion if this is going to work?
It's an open-source project, here is the link : https://tools.upverter.com/eda/#tool=pcb,designId=6f8c466dba06e940
Thanks for you time.
