Dennis - actually it has not dropped off. Latest surface finish de jour is selective enig/osp. Cisco, sun, Celestica and the majority of the far east are now using/supplying ENIG for switches/edge connector (plug to install) with the rest of the board being OSP for solderability. Requires the use of special dry film resist. New high temperature lead free versions also available and in use.
