Hello Songzhen,

That is a batch code. Therefore, it should be different.

Hi Ron,

Thank you so much for your support. Could you share the specific meaning for batch code? Does it mean the wafer production location or ATE location? Thanks.

Best Regards

Songzhen,

Not in this case. Year (least significant digit =1) then month in hexadecimal (June =6) then two encoded characters (effectively arbitrary).
