Hi Anni,

Please forward a photo of the markings on the top of the package.

I can then give this to our quality department to do further analysis and determine if these are valid parts.

Rob

Hi Rob,

     Could you send mail to you quality department  again, i am still waiting for your confirmation !  Pls ! Pls ! Pls!

Anni

Hi Anni,

I apologize for the delay.

I am pushing the group to get a firm resolution on this.

In the meantime, have you found any functional or performance issues with these parts?

Regards,

Rob

Hi Rob,

     We haven't found any  functional or performance issues with these parts by now .For we are not sure this production is correct.  we haven't use them .

      During inspection, we found the chip  we bought this time (date c ode 2018+) different from the production we bought  before (2015 date code)

      After confirmation with the you, we could  process the next step.!.

Hi Anni,

I am told the N logo should be on the die. From re-reading above and looking at the pictures.

It seems the N logo is present on the 2015 date code die. But not the date code 2018+?

Is this the correct assumption?

My other question is that is seems the two pictures are taken on different corners of the die. Is there a reason why?

Regards,

Rob

Hi Rob,

    Thanks for your reply.

Hi Anni,

Thank you for answering!

Can you please send two more pictures of the die in reference to the same corners where the N logo should be?

This will help give the quality department a clear answer.

Or if you can take a high quality picture of both die, but of the entire die, that would helpful as well.

Regards,

Rob

Hi Anni,

From the quality dept at TI the N logo should be on the die and in the same corner on both parts/ICs.

I am requesting from you to please forward pictures of the same die corner on both parts. In the previous pictures the of the two die, a different corner is shown for each part.

Our quality dept is requesting this.

Please send when you can.

Thank you,

Rob

Yes from the TI quality department. However, the two pictures sent to us previously were of different corners of the die.

Can you please send us pictures with of the two different die, but with the same corner of the die where the N logo should be?

This will help confirm our answer.

Rob

Hi, Rob,  

     Have you got confirmation from  your quality department?

   ANNI

Hi Anni,

I believe we have two threads open on this subject as I replied yesterday.

Anyway, the quality dept is waiting for new pictures from you that show the same die corner for each device you are referencing.

This is the only way to verify.

Please forward when you can.

Regards,

Rob

Hi Anni,
