Jeff,

Just to make sure that I read your reply correctly - should I infer from
your comments that you believe the IAg process 'likes' to have a
round-the- clock, steady-state flow to keep it stable and that the ENIG
process does not?  Or did you mean it the other way around, that the
ENIG likes round-the-clock operation?

Am not all that intimately familiar with either line and did not wish to
"read in" something that was not intended.

Steve

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.
