The process you refer to is still another option. Flash Gold on the
other
hand is electrolytically plated nickel and gold.
The direct immersion gold process was discussed by George Milad in a
paper
he presented at IPC EXPO last year. He would be a good contact for this
process.

Dear lee
I understand the new version of flash gold is direct immersion on
copper.
Is that correct. Has it been tested extensively?

Hope all is well with you.
I did not mention immersion silver since it has been discussed at length
in
this forum and most are ware that I am a huge advocate of immersion
silver
going bask to 1995 when I installed the first such line in North America
at
the AT&T plant in Richmond.
I mentioned Flash Gold because it is a relatively new coating (in its
present format) and is just beginning to catch the attention of the
OEMs.

Kudos from a long time lurker......
You're absolutely correct. Many many years of OEM experience with this
finish. Lots of fear over purported high cost of gold. There's a few
"application" secrets but it is the ultimate surface finish.
Now that the cat is out of the bag, how come you didn't mention
immersion
silver?

Another option is flash gold over nickel. Both are plated inline using
an
electrolytic process(as opposed to ENIG). The gold thickness is
roughly
two
micro inches. The OEMs that I am familiar with that have used this
finish
have reported very good results.
Most of the PCB suppliers providing this process are in China.

If somebody wants an extra smooth plating finish using lead free
plating
what material would they use...and what would be the finishing
process?
I've heard HASL is sort of rough...and it really doesn't apply
using
silver solder because of the melting temps.
Is ENIG (electroless nickel immersion gold) the way to go to get a
smooth finish?
thanks!
