Hi Werner,
I will try to still your curiosity. Sending you some delicate pictures
offline. Hope you cope with the views, so I don't get blamed for sending too
upsetting pictures. Is there possibly a 'Playboy' also for soldering? Can
imagin a midpage in Circuit World showing exciting IMCs and etched
samples?...He-he.
Have a nice day and avoid lead poisoning
Ingemar
PS. Will check in Wassink and AWS's handbook.

Hi Ingemar,
You did not give the thermal history, but to get "Ni/Tin IMC is many
microns"
thick you need to sit at high temperatures for a long time--not just one or
2
reflows. Just look up the Ni-dissolution rate in Sn in Klein-Wassink. I
would
love to see those pictures together wioth the history.
