Hi folks! Don Cullen's committee (sorry, I forget the IPC task group number) recently completed a very extensive electromigration test of immersion silver as part of a UL acceptance/teaming exercise. Those test results showed that the immersion silver did not migrate but the electrolytic silver did. I recommend you contact John Perry for a copy of the testing report. I have recently used the test data as topic information in the "doesn't immersion silver migrate?" design team discussions.

How would this impact the 2mm press-fit connectors? Anyone willing to share their experiences? Thank you in advance.
