Looks like an LGA-style connector except with alignment pins and screws for tension instead of an ILM. Edit: The basic connector design appears to be very simi

Looks like an LGA-style connector except with alignment pins and screws for tension instead of an ILM. Edit: The basic connector design appears to be very similar to Samtec's GMI range: https://www.samtec.com/products/gmi https://www.samtec.com/products/gmi including the actual contact array apparently being double-sided, so it would appear that the base board for these would also just have a land pattern. So if you damage some of the contacts, the "compression interposer" should be cheap and easy to replace.
