74ALVC164245ZRDR Moisture Level

TI p/n 74ALVC164245ZRDR, is listed on TI's datasheet as being MSL1.  Being a silicon BGA, I don't see how this is possible. 

I think it should be MSL 3.  After digging around today, we found the following on the attached .pdf:

 

"ï Moisture absorption also affects the ball off issue. The package was qualified at Moisture Level 2, and has been released at Moisture Level 2A.  The first and second reflow must be completed within 4 weeks."

 

This notice was published in the last few days.  2A is better than 1, but still not my anticipated 3.  Can someone confirm the rating?

Thanks!

  • Jason,

    This link http://focus.ti.com/quality/docs/partnumsearch.tsp?templateId=5909&navigationId=11214&mslType=true also indicates MSL1 like the Data Sheet. The attached App. Report indicates MSL2. I'll see what I can find out from the product group. Could you attach the memo you referenced to the Forum post?

    Jeffrey,

    I was told from TI via email today the following:

    "Ok, have confirmed with packaging team that it is MSL1/260C as on the website, the document was published in 2000 so it does not reflect the current product.". 

    Please let me know what you find out.

    From QA

     

    Both the data sheet and assembly/test traveler indicate MSL1/260C.

    Chris,

    Any chance they can explain how that's possible?  I don't understand how a silicon BGA can be MSL1.  Is there something they are doing differently than everyone else and differently than nearly identical product from TI that is MSL3?

    Please let us know as this matters for qualification of a product.

    Jason,

    The packaging engineer has recommended MSL2+ for this device and is working with the Product Line folks.

    So, by reading that, the final result is 2+ then?  What is 2+?  I am familiar with 2A. Also, do you have a timeframe on this?

  • In reply to JasonHaedt:

    Please use this device as Level 2A.
