Hi Joe, It was the argument you advance: "Now the gold flash on
nickel/palladium/gold is only 30 to 150 angstroms thick, which is way below the level where
you'd have to worry about gold embrittlement in the bulk solder (like by a
factor of 50)" that led to the exemption of ENIG.
On the other hand , where to you get the factor of 50 from? It also presumes
that yopu are happy with ENIG--not everybody is.
