Hi Patricia,
You can find it on IPC-4552 (spec for ENIG for PCBs). It is min. 2 u" for
gold. 118 to 236 u" for Nickel

Dear Friend,
Did IPC indicate that immersion gold thickness have to be minimum 2u" gold?
This 2u" thickness is referring to the gold thickness only or it is the
total thickness which includes the nickel too? Which IPC documents
indicates this?
Hope to have your expertise advise.
Thanks & Best Regards
Patricia Lui
