This is curious. Just wondering if you really mean Sterling silver.
Sterling silver is 92.5 silver.

Subject: [TN] Sterling silver finish
Hello Technet,
We were approached by our board shop to have some of our boards finished
with Immersion silver.
I hope that someone can provide me, off-line if required, their experiences
with it, be it positive or negative.
Do I have to change my process? thermal profile, solderpaste, flux, etc
Here are the selling points:
Very flat finish, great for QFPs, MBGAs, 402 packages.
No nickel therefore, no embrittlement or black pad issues.
Ay feedback is appreciated. TIA
Regards;
Francis Sun
