DS125BR111: CTE

Tamren Smith
Prodigy 205 points
Part Number: DS125BR111


Tool/software:

I am reaching out to request Coefficient of Thermal Expansion (CTE) data for the component we have sourced from your company. Could you please provide us with the CTE values ? We would appreciate it if you could provide the CTE values in ppm/°C or ppm/°F, as well as the temperature range over which the values are applicable.

    Hi Tamren,

    I'm requesting this information from packaging.  I'll try and get an ETA on and answer for you.

    Regards,

    Hi Tamren,

    A couple additional questions:

    What is the end application (Why is the package-level CTE value needed)?

    We have two options for modeling, which would you prefer:

    1. Non-directional CTE (assumes CTE values are the same in both x- and y-directions, regardless of package or die aspect ratio): <1w for estimate

    2. Directional CTE (provides both x- and y-direction CTE values): ~2w for estimate

    Regards,

    Undrea
