AWR1642BOOST: The ant is damaged by rust

Part Number: AWR1642BOOST

Hi,

I found the ant in my board is rust, like the attached pic.

I bought it 2 months ago.

I wonder if this is a common issue? Can I ask for a replace?

Thanks.

    Hello,
    This is just the oxidation of the immersion silver on the PCB due to exposure to air for long period of time. There is no impact on the RF performance and this has already been analyzed by our material vendors.

    The recommendation is proper store the PCB to reduce the oxidation.

    Thanks,
