Dear experts,
Our partner procure these from franchise source with DC:2105+.
Parts were in tape and reel and kept in temp controlled environment.
They observed on random pieces picked from the same reel:
a. contamination marks on the heart plate on the underside of the chip.
b. exposed copper at the edge of the contact pads
They would like to conduct a solderability test but before they do that, please advise if:
1. (a) and (b) are norms that occur in the process of your manufacturing
2. our partner can proceed with using the parts without concerns.
Attached are pictures for reference
