True, silver is a lower cost to a board shop who has both lines. But if a customer has a supplier spec'ed in who only has ENIG, the cost to the customer will be the same due to the supplier having to sub-contract out, or they spec in another supplier who has both, or work with the supplier to commit work to support the new line.

Deposition processes are high maintenance and need to be run day to day. Having to keep this line loaded with panels influences my view of ENIG performance internally and in the field.

If your favorite fabricator does not have an in-house Ag line then ENIG may be cheaper or vice versa. If they have both then, yes, Ag is likely cheaper.

From the sounds of it, it seems to be a wash. If that is the case, from a commodity perspective, I would think you would get a cheaper price for silver, so if shelf life is not an issue, why not go with that? Chad -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Dave Seymour Sent: Tuesday, 15 August 2006 3:33 AM To: [log in to unmask] Subject: [TN] Immerison Au vs Immersion Ag We are having a little talk about surface finish for RoHS compliance. We have been doing Immersion Gold for 10+ years and are starting to switch to Immersion Silver because some feel that Silver is a better finish for RoHS compliance. I can't find anything that says one can not be compliant with Immersion Gold and I'm trying to figure out why the surface finish should change at all. Could someone point to some articles, opinions or sources that might help resolve the issue? I'm out doing some web looking now.
