Steve,
It well may be a surface contamination/cleanliness issue (prior to plating).

Subject: [TN] Peeling Plating...
YAY! IT'S MONDAY!!! YAY!
(Ya'll are probably saying; "Sheesh, what's Steve been smoking?")
I'm not smoking anything...I said "YAY" with my tongue in my cheek, so to
speak.
It's Monday again, and I have a couple of pictures for you to look at and
let me know
if any of you have seen anything like this before. We got these pictures
from our customer
asking us if we know what might have caused this. Go to:
http://www.stevezeva.homestead.com
and look at "Plating Peel" and "Plating Peel Close-up". Obviously, this is
something that
you don't want to see on component leads. It kinda' looks like the lead is
shedding it's
skin...
We're going to contact the component vendor about this to see if they can
shed some light
on why this is happening...I wished I had the assembly here that the
pictures came from, but
we only have the photos right now.
Anybody ever seen this before?
"Monday, monday...can't trust that day
Monday, monday...sometimes it just turns out that way
Oh monday mornin' you gave me no warnin' of what was to be
Oh monday, monday...how could you leave and not take me."
