Hi Werner, I see ENIG from supplier side and it seems that reaction on this process depend on complexity of the board (geometrical and electrical). There is a niche where everybody happy (or we can make them happy) - PCB manufacturers and PCB assemblers. When you push envelope too far a lots of irritation rises often from both sides. Its like changing plating hole diameter from 18 mil to 12 mil - no problem, from 12 to 8 mil (HAR) some times almost revolution required in PCB shop. EPd is a good idea and process, but it is additional control step in manufacturing chain which usually effect general reliability. I believe when ENIG or ENIPIG possibilities are exhausted one step finish should be used - OSP,Tin,Silver,gold whatever and ENIG selectively if needed.
