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.

   Can someone share any reliability data they have come across with
regards to a sound
metallurgical solder joint with regards to IAu and LF Process?
