DS90LV019：marking

I want to know that the positioning points of the chip in Figure 1 and Figure 2 are different, what is the reason for this, and is this normal? Thank you!

Hi Tony,

This is a common difference that will show up occasionally when different machines are used to package or label different lots. All other formatting for common devices should match, but font and minor graphical differences like this can pop up from time to time. 

I have confirmed that both of these markings are correct for DS90LV019TM8B5 and are different lots (a few months apart, same year) from the same fab. 

Let me know if you have any more questions. 

Regards, 
Eric Schott
