Question about USBc connector and its footprint

[Hawaslsh]

Hello All,

I was looking through a few USBc parts for an edge mount PCB and i came across a connector that confused me and I thought I'd ask the community. The part in question is the UC-31PFFH-QF7001, I linked the data sheet i got from the company.

Above is the footprint and 3D model from the company. Each top side (orange) pad/net has a corresponding via associated with it. I can't tell from the drawing in the data sheet, are the pads and vias internally connected through the connector? For example is B6 (NetR12_2) internally connected to A6 (NetR12_2) and there is no need to route a trace connecting them? I suspect this is true for convivence of routing, but I wanted to ask instead of assuming.

Thanks in advance,
Sami

Read the datasheet thoroughly. Signals with different name have different function will be normally not connected to each other.

Only a few signals use multiple pins, e.g. GND, Vbus.

Read the datasheet thoroughly.

That's what confused me, hence my question. I take it from your answer; the pins which share Vbus are connected internally? Also DP1 and DP2 are not connected internally?

Thanks for your patience

That's all correct.

Hi,

I don´t think that the 4 VBUS pins are connected inside the connetor.
I recommend to connect them all on the PCB.

May be a misunderstanding, no pins are bridged inside the connector.

Because USB-C can be plugged in either direction there must be mirrored connection duplication in the socket. USB-C jacks typically do not internally connect the mirroring in the actual USB-C jack, leaving it up to the PCB layout to make the common mirrored connections.
