Card-Edge socket with thru-hole footprint

Layout Footprints
1

Hi.

I’m looking for a comparable example anywhere (default KiCad library or elsewhere on the internet) of a “proper” example of a card edge socket that mounts to the PCB with thru-holes.

I don’t expect the pitch, dimensions or the number of pins to match, but I’m confused about how such a connector should look in a footprint.

I’ll be using an uncommon 3.175mm pitch (example https://www.aliexpress.us/item/2255801094078491.html ) so I’ll expect to adjust the pitch and the number of connectors myself in the footprint editor. I’m figuring out how to edit footprints well enough so far.

The card-edge sockets I see in the default library confuse me, because I’m not sure if I’m looking at the contacts where they contact the card-edge itself, vs the round thru-holes that I’ll be connecting the traces to in the PCB designer.

For example, Samtec_MECF-08-01-NP-L-DV_2x08_P1.27mm_Socket_Horizontal in the default library. It’s in the Connector_PCBEdge section, but how do I see the round thru-holes for the back of it where it mounts to the PCB?

Much appreciated, thank you!

Hi, that is a SMT footprint… no holes. That whole library is SMT.

Ah, that explains my confusion. Is there ANY thru-hole card-edge socket in the library, perhaps named something else cryptic?

Connector_Hirose. Hirose_DF11-32DP-2DSA_2x16_P2.00mm

Your aliexpress item will have a similar footprint but 3.175mm pitch between pins and 6.5mm between the two rows

OK, thank you…that looks much better, easier to follow, thanks!
I’ll copy this and make my own custom sockets with this,

This is exactly what I was hoping to learn, and thank you!
Best,
AJ

:grinning: Thanks again!

I really appreciate all the help!

KiCad “only” has generic connector symbols, and none of them have a footprint assigned by default. So you can use any of them. There are different versions for the ways pins are ordered, so that is a detail to be aware of.

Awesome, that makes it simpler than I was thinking then.
