Are these counterfeit devices ????

[Altera_Forum]

Hi All, 

We have recently starting having many problems and failures from new of the EPM7128 FPGA devices. I have enclosed a photo of just two of our failures, and even though the top of the devices are both labelled up with identical numbers/batch numbers etc, I am wondering why the bottom of the devices are stamped with different countries(Philipines/Korea).  To me this would indicate a classic fake device, but can anyone out there verify these as outright fakes at all ??? Thanks Very Much. Al.  (click image for larger hopefully)  https://www.alteraforum.com/forum/attachment.php?attachmentid=9286

I can't verify that they are fakes, but have different countries of package manufacture, and have then same batch numbers on both sounds suspicious.  

 I know Altera has had issues with counterfits in the past.  They probably do have multiple sources for packages, but I would assume the markings would be sligthly different between package houses.  Pete
