Our customer bought the part ISO7220ADR.When they received the part,they found the pin of the chip is black.They want to know whether the pin is oxidizing or not.If it is not,please tell me the reason why the pin is not silvery.

Thank you.

    PS: Most of the team will be out for the holidays next week, so our response times may be longer than usual.
