TPS7H1210-SEP: TPS7H1210MRGWTSEP

Part Number: TPS7H1210-SEP

Tool/software:

During Incoming Inspection, we have obtained the following results when measuring as part of Weight Check testing:

unit# 1 = 65 mg

unit# 2 = 65 mg

unit# 3 = 64 mg

However, TI datasheet ref.: SBVS414 – NOVEMBER 2021 states that weight should be 83.6mg: 

Could you please review this data and provide us with TI feedback?

Thank you,

Kind regards,

Pedro.

  • Hi Pedro,

    The mass estimate comes from the material content report, which totals 83.6mg. I will look into reconfirming the reported value. In the meantime, is there another device or object with a known confirmed weight that you could weigh in order to verify that your scale is providing an accurate measurement? 

    Thanks,

    Sarah

  • Hello Sarah,

    We have performed the measurements on 3 of the pieces of this batch, resulting that the 3 units have these values: 65mg, 65mg and 64mg.

    With regards to the calibration subject on this equipment, please note that we are measuring everyday parts without any other deviation on those different devices.

    Once you have completed the reconfirming action on material content report, please let us know, just in case there is any update to be taken into account.

    Thank you,

    Best regards,

    Pedro.

     

  • Thanks for confirming the calibration on your end Pedro. I am obtaining units to confirm a matching measurement on our end and will look into any possible discrepancies in the material content report so we can confirm from that perspective as well. 

    This may take a few days to complete. I will reach out again with an update as soon as I can.

    Thanks,

    Sarah

  • Hi Pedro,

    I measured one unit and confirm the same weight as you: 65mg.

    Material content masses are calculated individually to estimate a baseline mass value. There can be some difference between the theoretical mass and the actual measured mass due to real life manufacturing and assembly conditions. With that said, the measured value is consistent.

    Thanks,

    Sarah

  • Hi Sarah,

    Thank you for the actions and the reply.

    According to the result after the measurement, is it possible that TI can decide to update TI datasheet ref.: SBVS414 – NOVEMBER 2021? 

    As a more quick corrective action, could you please issue a letter stating that TI confirms a mass value for these parts around 65mg, instead of the value listed in TI datasheet ref.: SBVS414 – NOVEMBER 2021 (83mg)?

  • Hi Pedro,

    Issuing letters on behalf of the company is not something I can do. I can, however, note this in our revision tracking in case it is possible to address in a future datasheet update. 

    Thank you,

    Sarah

  • Hello Sarah,

    Can you ask for to a supervisor permission to issue the letter?

  • Hi Pedro,

    To clarify, this is not something my team can do on behalf of TI. It appears likely based on our small sample of separate measurements that the mass for this lot of devices averages fairly consistently around 65mg, but there is bound to be some slight variation between units and different production lots. The mass of the units is not a specification that we qualify against so we cannot make specific guarantees about it. 

    Thanks,

    Sarah

  • Hello Sarah,

    OK.

    In formers email you stated: "I can, however, note this in our revision tracking in case it is possible to address in a future datasheet update". 

    Could you please at least provide us with such "revision tracking"?

  • Hi Pedro,

    I do apologize but the revision tracking system is an internal one that I cannot share. Would it be acceptable to utilize this E2E thread as documentation of the general nominal mass we both measured? Or is there a different goal you're hoping to achieve? 

    You can also sign up to receive notifications if a datasheet revision is published to ti.com through the part's web page. Would this work for you?

    Thank you,

    Sarah

  • Hello Sarah,

    OK.

    We will close this subject by adding in ATN Incoming Inspection report the following text:


    “Deviation of ATN measured values during Weight check versus TI datasheet ref.: SBVS414 – NOVEMBER 2021 (in which it stated that weight should be 83.6mg) was double-checked with TI.

    TI feedback was that they measured one unit, confirming the same weight as ATN: 65mg.

    TI explanation about this subject is that Material content masses are calculated individually to estimate a baseline mass value. And that there can be some difference between the theoretical mass and the actual measured mass due to real life manufacturing and assembly conditions.

    Finally, TI confirms that based on these statements, the value measured by ATN is consistent”.


    Thank you for the actions and support provided with this incidence.

    Kind regards,

    Pedro.
