10-contact FPC socket has 12 PCB terminals

Question

I have to place an FPC socket on my PCB. I selected 0.5 pitch and 10 contacts connector. Everyone has 12 PCB terminals instead of 10.

I am confused, what are those two extra pins for?

To hold the connector in place. They are "anchors", though various companies call them with different names.

Thanks a lot for the answer, so i don't have to wire them in my design? – Mukund May 04 '23 at 16:13

No, you don't. They are just pads. – Davide Andrea May 04 '23 at 16:16

To be clear to the OP about connecting them in the schematic: there is really nothing to connect. There is no electrical connection from extra pads to the FPC; they exist only to provide a solid mechanical connection to the PCB. – spuck May 04 '23 at 22:34

Connecting them to groundplane with vias can increase the strength of the pad to prevent it from being lifted off the PCB. – jpa May 05 '23 at 08:05
