Hello Farabi
Thanks for your reply.
We bought the parts from a broker in China, let’s say on the grey-market via a unpopular local partner. If I remember correct, he mentioned something like IC planet…
As we tried to be on the save side, we performed x-ray and the pictures show some really small different, which we guess could be normal tolerances.
Do you think, it is possible to support us in verifying the genuineness?
We could provide DC’s and x-ray pictures.
Thank you so much in advance
Viele Grüße/Best Regards
Helmut
