Hillman Sent: Tuesday, July 28, 2009 10:01 AM To: [log in to unmask] Subject: Re: [TN] FORMULA FOR DETERMINING GOLD PERCENTAGE IN A SOLDER JOINT 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.
