Grace,

Just as the TMP103 case you linked above, this is normal for our devices.

Hi,
Sorry, I may explain wrongly. I am actually referring to the Ship Track Code highlighted in the picture below. Is this normal to have same STC code for different reel?

Hi Grace,

Yes, this is normal. As Ren pointed out in the TMP103 thread, a single wafer can often consist of several tens of thousands of devices. These devices will all often travel through our assembly processes and test together. Assuming the SPQ is some number less than the total number of units under test, then all the lot and trace code info will be the same across all of these reels from the batch.
