Please help to check whether this material is oxidized.Thanks

    Dora,

    This does look oxidized from the image. Do all the devices look this way or just the one? And was the packaging damaged in any way when you received it?

    I'm going to reach out to our quality team and see if any other actions or measures can be done here but in the meantime, I will also point you to the TI Customer Return page. Since you purchased this from the TI store directly you'll be referencing the Return Situation in yellow:

    Dora,

    So i've reached out for further assessment from our quality team and it seems some more questions may be needed to be answered before knowing if we can definitively say if this is an oxidation problem.

    So these devices are MSL-3 and should have a moisture indicator card enclosed with the reel. Could you check this indicator and share what it shows?

    Additionally, these are NiPdAu plated leads, roughened for improved adhesion, which can make the surface appear less shiny and darker than a non-roughened lead frame. Have there been any problems soldering this or is something more visibly contaminants on the surface? The device may just appear darker than you're normally use to but is still functional just the same!

    Thanks,
    Rami Mooti

    Hey Dora,
