Part Number: SN74LVC1G32

For SN74LVC1G32DBVR, we have done X-ray irradiation of date code22+ and 23+ products and found that the internal frame and lead are inconsistent

Could you please help confirm the reason

Thank you.

The SN74LVC1G32DBVR is made at five assembly sites, so it would be possible that you see up to dive different lead frames, even for the same date code.

Does the red arrow in the picture point to the wafer? Why are the wafer sizes inconsistent? What is the reason

Yes; both the lead frames and the dies can be different.
