dear. max

have a good news ?

wait your reply..

Hi Jennifer,

I just heard back from the assembly site today.  They only use the line-style pin 1 indicator on this package and do not use the dot for this package type.  The lot trace code that is printed on the dot-style package in your photo does not correspond to any lot we have manufactured (at least as far back as 2009).
