Welcome to hell. A fellow engineer at my last employer went through this. 
Here's the thread if you haven't seen it already:

Sounds like you're going to have a lot of fun (yea, right..). From the email 
thread, Inge says no more than 10-pins at a time. I'd take that to the bank 
if I were you...

I too have now entered the single-pin-hell of these connectors.
Looks like we will be building tooling to press in multiple pins.
Can anyone recommend an optimum number of pins to press at one time?
Thanks,
John
