Now I know what Doug meant when he said he liked the movie better (so much for his celluloid-free diet). Did this originate with his initial confusion between Cliff Notes and Cliff Bars?

I recommend you try looking in the closest "big" University library as they typically have copies of publications you can purchase for inexpensive prices. I also use the Linda Hall Library in Kansas City for getting some technical references. Internet access and digital storage has made getting technical publications soo much easier. Good Luck.

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.
