Victor - as part of a Pb-free consortia back in 1999/2000, we tested ENIG with multiple surface finishes on components and different alloys. Parts were thermally cycled from -55C to 125C for 1000 hours. Data was published at IPC fall show in Miami - cannot remember the year but I am sure someone on the net does.
