SN65HVD1050DR x-ray difference

I was recommended to come here from the support team and post on this X-ray difference.

Both were from TI but showing totally different x-ray images. 

The only difference is different batch?

Is there any PCN to explain this difference?

  • JY,

    IT looks like this may be slightly different lead frames. Can you verify the top marking on both devices? We'll be able to verify where they came from and when they were assembled.

    Regards,

  • I only have the label of the unit on the left and the top marking for the unit on the right. Can it help?

  • JY,

    Thank you for this information. I will look into this and get back to you over the weekend.

  • JY,

    I looked into this and found that there are some PCNs related to assembly materials, which would explain the different lead frames that you're seeing in the X-ray images. That being said, when I look up the top marking code for the device you shared, I'm not able to find the lot. I'm working internally on this to find out where that device was assembled and will get back to you.

  • JY,

    The difference between these two devices is the assembly site, as I suspected. One device was assembled in Taiwan and the other in Malaysia. Since this device was released in 2005, it has gone through difference A/T sites and BOM changes over the years. In our PCN database we have several referencing this.

    Please let me know if you have any other questions.
