Dear Steve
Peel off once again on the left over fingers may be twice to be sure. Check
for small bubbles. If so reject. If not clean and solder the peel off area.
However the black at the border is sure going to peel.

Vendor needs to improve process.

Subject: 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,
