Lead Free Surface Finish

What is the shelf life for PCB's with a Sn/Ag/Cu surface finish (96.5/3.0/0.5)?

Can you steer me to some supporting documentation?

Experts Comments

There is limited data on shelf life for SAC HASL

I would recommend you use the IPC steam aging test to independently confirm shelf life.
