EPP or at least EPP Europe is still in existence
http://www.epp-online.de/epp/live/start/1.html
However If you Google the words in the title you will find a number of
libraries who will sell you a copy of the paper.
On my HDD I find I have a copy of a paper
"Effect of Au on the reliability of fine pitch surface mount solder joints"
By Glazer - Hewlett Packard, Kramer - University of California and Morris -
Lawrence Berkeley Laboratory which is pertinent.
Finally you can down load an Application Note "Soldering to gold" which
deals with this topic at a lower, pragmatic level.

Jon,
You will have to go to a library, probably a tech one or a big one. I have
only been able to find sporadic issues from November 2000 to June 2003 on
line.

Hi Jon - the folks from Lockheed published a very good article on the impact
of gold on solder joints including the calculations/material
parameters/graphs that would be useful to you. Pull a copy of this
article: "Effects of Gold Diffusion on a Near Eutectic Solder Joint", S.
Enwright, Electronic Packaging & Production, June 1998, pp 68-72. Good Luck.

[TN] FORMULA FOR DETERMINING GOLD PERCENTAGE IN A SOLDER JOINT
Does anyone have or know where to find the formula for determining the
amount of percentage of gold in a SMT solder joint? Appreciate any
help, Jon
