Part Number: SN65HVD485E

Tool/software:

I would like to inquire about the label show d/c 2309 , the lower left is 33, but the tape reel is sorted 33 and 34 not in order, and laser marks vary in thickness, is this normal?

    Hi Howard,

    I'm reaching out to one of our product engineers to get their opinion on this. I'll get back to you when they provide me their feedback.

    Hi Howard,

    See comments below:

    "The A/T site date code is when the material got marked. So if its end of a month/start of next month, the marking on that lot will be 32 or 33(just an example) if it got processed over 2 days.

    While testing, the units from both days (32 and 33 marking) will be all together without any order; and based on what got to test first, they will be arranged in the T&R accordingly.  

     

    The marking variation is probably due to different machines usage. They both should still be within spec."

    Based on this, it seems like these kind of variations are okay.
