Does your AD9680 made from a magnetic body?
When the around temp is 13C to 161C, AD9680 become a magnetic body, correct?
I confirmed your material declaration for AD9680.
So I found that AD9680 use Sn for plating or solder sphere finish on there.
The beta-tin(temp. 13C to 161C) have the paramagnetism as you know.
On the other hand, the alpha-tin(temp under 13C) have the diamagnetism.
Our customer will put AD9680 in strong magnetic field like a MRI.
So this info is very important for him.
