Hi Wayne!

Got your pictures posted, they are here:

It could be that they really aren't counterfeit, but got somehow
mis-marked by Fairchild and then re-marked to fix it. But if it is
indeed counterfeit, you'd be surprised at what is of value to those that
have labor costs at next to nothing...

Subject: [TN] Maybe not counterfeit, but definitely weird!

We needed to do a bit of training on some DIP parts, so for some
"dummies" I bought one of the cheapest things I could find at DigiKey.
Turned out to be a 74HC14 part, and they cost 0.29 in 50pc quantity.

<I have copied Steve on the pix so hopefully he can get links up to
them>

The first picture shows the surface of the parts.  They all look
identical.  The tops have been selectively sandblasted, then a laser
marking machine was used to put a new marking on them.  Seemed like a
good chance the parts were counterfeit, so I authorized using acid for
decapsulation to check out the die face.  The second picture shows that
the wafer masks were created by the manufacturer listed on the re-label,
anyway.

Now if I paid 0.29, DigiKey is probably paying about 0.15.  How can
anybody go through this and make money?

Wayne Thayer
