    Hi Stefan,

    I found this in a recent E2E post.

    "The 3 designates year and is deciphered to mean (2003, 2013 or 2023).

    The 1 designates month and is deciphered to mean January. 

    The K designates manufacturing site and is deciphered to mean Malaysia.

    The underscored G4 is a specific mark to denote the IPC/JEDEC standard that the device is built to."

    Thank you.
