Hi Mancy,


This is what I found from the internal teams regarding the difference in the appearance and x-ray from your side.


The different for both is due to substrates SCC ( DC 2043+) or ASEMt ( DC 2137+).

ASEMt substrate is using old selective gold process that’s why we are seeing more gold on bottom site. But then, both are qualified substrates.


I hope this helps for your concern.
