Looks like the finger to the left of the arrow is thinking about peeling
also.  Not that I am an expert but my recommendation would be strip and
replate all of them.   Do it now and not have to worry or deal with it on
a customer return in a couple months or sooner.
The bigger question would be what caused this to occur.   You get all the
way thru Conformal Coat then this happens.  Not a happy ending...

[TN] Gold Plating Peeling...






Well, I just got back from "Sin City", and as they say; "no rest for the
wicked".

I really wasn't that wicked, but I was confronted with a new problem this
morning.

We just built some assemblies and conformal coated them, but when they
were
being
de-masked, the gold plating on the fingers started peeling up! Check out:

I have a couple of questions:

Can I repair this?

If I repair this, should all fingers be stripped and repaired?

Kind regards,
