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.

Silver is by far lower cost than ENIG - materials, process and space needed
to maintain a 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.

The "price" would depend on the source.  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.

I am hearing a lot of discussion about reliability and compatibility.
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?

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.

Thanks
Dave
