Hello Hani,
Ask your client for a PPAP checklist, get waivers on items you did not do
(design for example).
This is a useful starting place.

It is well worth an hour to read and follow links if you have not done one
before.
The FMEA & APQP take the most time (in my experience). AIAG has some useful
documents.

Subject: [tinwhiskers] PPAP for a bare board
I am looking for some input to having a PPAP done on a bare board. I usually
visually inspect the boards per IPC-A-600 and relay on the manufacturer to
provide a CoC.
Now I need to get a PPAP done. Looking for your input as well as a Lab that
can do it. This is an ENIG fished board with a BGA foot print. still a
leaded process I think knowing the concentration of the P, Ni, C as well as
the thickness of the Au. I should check to see if IPC-4552 covers the
concentration levels.
I also should check the cleanliness level as well.
I am looking for a lab that does this work. Also any input to other gotcha
that I need to inspect for.
Thanks,
Hani
