Just as an aside on that, I doubt you really need the hard gold fingers
on a prototype board. You do need something to stop the copper from
tarnishing, and hard gold is almost certainly the most durable option,
but I can't think of any obvious reason that an ENIG or immersion
silver finish wouldn't work just fine on the fingers for a moderate
number of insertions.
I second that one. Most of the time, your card sits on the adapter
board, so if you break anything, it would be the connectors on the
extender. So make it cheap, you will need few shots at it ...
