Hello,

I'm looking for CTE values for the following part numbers, the information is needed for a solder joint reliability analysis. Thank you

    For the

    LM2903DR

     CTE (ppm / °C) ( (a)bove and (b)elow Tg ) CTE (a): 35 CTE (b): 9  

    LM2903DGKR

     CTE (ppm / °C) ( (a)bove and (b)elow Tg ) CTE (a): 34 CTE (b): 8  

    Note that the high-volume devices that you have listed are assembled at multiple assembly sites across the world, and the mold compound may differ depending on the site. The above numbers are for the most common compound at the larger sites.

    We cannot get into the compound details too much as this is considered proprietary information.

    Also note that you have multiple devices from multiple disciplines - you really should separate out the logic, amplifers, regulators and references and post to the appropriate forums.

    Hello Gabriel,

    I see you clicked "This did NOT resolve my issue".

    I provided you the data for the devices under my control. I cannot access the data for the devices in other product lines.

    You will need to post to the relevant forums.

    Below I have looked up which forums the devices belong to:
