Received an unusual request for quote with a fab note callout for the
following.



1.      Plate 200/50 microinches SnAu (very hard)





Now I read that as 200 microinches of tin plating, followed by 50
microinches of Gold and thought to myself..huhhhh!!!



I contacted the buyer and he agreed it was quite unusual but they indeed
need gold over tin. The buyer could not explain why, so I thought I would
see if others have performed this process, and why such uncommonly mixed
coatings???
