Hi Victor - here is the reference material I promised to send out. It is a paper from the 1996 SMI proceedings that Rockwell Collins and ECI Technologies published. The "version" of ENEPIG we investigated had good solderability and outstanding gold wirebondability.

I want to be knowledgeable of the process versus hard gold and pure ENIG for commercial use. Victor, -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of David D.

One of the big drawbacks of the finish is its cost. There are a couple of good reference books that talk about ENEPIG. When I get back off business travel, I can send your the exact references.
