Fairchild Diodes SS14 bad factory policy ; beware !

[Sagaert Johan]

Hi

I wonder how in heaven its possible to get explain this.

I got a batch of PCB's witch an SS14 diode on it. made in China.

After testing ,it turned out that roughly 40% of the diodes have the
component stamping 180 degrees flipped.!
What should be the cathode is the anode !
Someone seems to re-sale trash...

I think companies like Fairchild have a an ISO 14xxx or other quality
certificate, but this issue shows that there are
serious holes in it....

Of corse this only seems to happen in China.....

I have personal knowledge where critical component measurments are disabled
to improve yield ...
(Fameous .company with roots in holland and producing film capacitors in
China )

Second possible is that the SS14 are Counterfeit parts .....

Second possible is that the SS14 are Counterfeit parts .....

Could it be possible that the parts are made and labeled by a
subcontractor, and they had someone get hold of the rejects and resold
them?

First: Did you get certs from the factory?
Also: did you speak with the product engineer?
And: Did you notify the distributor?
What have they said about it?

An unsupportable allegation may be your idea of a warning, but I
can't believe you have proven anything yet!

I have never had a bad lot of parts from Fairchild, but I did get
a few bad ones which they cheerfully replaced.
