How about creep corrosion? Some environments are harsh. A simple
rubber band can attack the finish. sulfur

Subject: [TN] Using Pressfit connectors on an Immersion Silver PWB
Has anyone experienced any issues with using pressfit connectors on a
circuit board that has Immersion silver finish? Do I need to worry about
any tarnishing inside the pressfit connector holes? Since there will be
no solder, the holes will remain open, and thus I was wondering if there
have been any issues with this.
I am considering using immersion silver as a finish for a high
reliability design, and I have never had issues using it with thousands
of medical and military and other applications, including
telecommunication blades where pressfit connectors were used. However,
this is a military application, and I want to know if there are any
potential issues before I commit to using it for this application.
