I was also looking for some updated PCB finish data and found something interesting that I don't know if many people have seen. It's a presentation done by CALCE called; "Assessing the risk posed by Tin Whiskers". It's very, very good and I thought I would share my find....

A few of us were questioning that the data was so old, crust was forming, which is appropriate for a pie chart. Let us know if you get any updates.

Immersion tin and immersion silver are not even on the chart of finishes. IPC Suppliers Council documents this quarterly, but the information historically is limited to the suppliers of the data - the providers of surface finish chemistry. I will see if I can get permission to publish more current information.
