Reliability of edge connectors for production
Edge connector sockets, like you might put on a motherboard, are not designed for a large number of insertions.

If you want a way to make a temporary connection to pads on a board in a production environment, build a fixture that incorporates pogo pins, which are expressly designed for this kind of application.

I once used a modified "dip clip" for a similar purpose in a low-volume production environment.
