Hi Victor! You may want to try to get a copy of IPC-GH-850 "Handbook of Interconnection Contact Finishes" - it has quite a bit of useful information on finishes and test methodologies. Just a warning - the last time I recommend someone get a copy of the 850 Handbook the IPC folks had to do some digging. My copy is dated August 1990 and the Handbook may no longer be active. Good Luck.

Is there a more comprehensive data metric that also address Insertion Cycles per gold plating thickness on edge-board connectors and areas not to be soldered. Many suggest contacting the vendor. However, I feel there should be some industry established guideline. Victor G.
