Alistair - as part of the 4552 specification testing, we ran ENIG at 2
microinches for 1.5 million cycles for a keypad type application. We stopped
because the membrane was breaking down but not the ENIG surface. The data
can be found in the tech paper that is in the appendix of IPC-4552

Subject: [TN] ENIG vs Hard Gold
Hi to everyone,
Could someone please let me know or indicate where I can obtain
information on the relative performances of ENIG and Hard Gold in
keyboard applications?
Many thanks in anticipation.
