pcbusbusb-2usb-cvia
I am working on a design which utilizes a USB type c connector. My question is what is the proper way of connecting the duplicate D+/D- pads? and do you recommend a specific trace width/ via size?
You can check how I did it in the attached screenshot. I used 8 mil traces and 8/16 mil micro vias.
Sometimes called a "Solder-Short" pattern. To create it you could use two half-moon shaped pads placed very close together, be sure to keep solder mask off the junction area. Usually the idea here is if you need the two signals shorted you then put down a solder blob covering both pad ends. With this method you start out with an open.
A way to create it and still keep the net connection would be to use an oval shaped pad with an oversized (non-plated) drill hole. You then run the two traces to the pad from opposite ends. The drilling of the over-sized hole physically cuts the pad in two. Re-solder the connection if needed later on.
Yes, through-hole components will have copper pads on either side. Similar to this:

The traces have to conform to the USB standard, 90 Ohm differential impedance. The trace width is dictated by your PCB stack-up and height over the ground plane.
