I got some good feedback from a couple of engineers working over the weekend
and have produced some more images to show "Fisheyes" now. I will reliable
the first examples circulated as "BugEyes" as they remind me of the VV
Beatle.
I did find a reference to FishEyes in a NASA standard with a black and white
photo. There is also a colour image in their inspection guide.

In regards to plated-through holes, it would probably be Walleyes.

I have been putting together some inspection standards for a new
workshop in
Germany. I have found a number of references to "Fish Eyes" but never
seen
an example. It's a common term but seems to be elusive in terms of
actual
examples.
Would the images at the following link be considered "Fish Eyes" by
users or
are we looking for more subtle examples like two bubbles between IC
leads??
