You opened that controversy again, John!
Many favor immersion silver as the best "all around" finish. Some prefer
to stick with ENIG and all of its associated evils. More and more are
moving to immersion silver.

Subject: [TN] best plated surface finish

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!
