I just read an article in the " Advanced Packaging, April 2001" about pure tin plating with the result that no whiskers were found after 18 months 50°C/85%. Well, no secrets told in the article but quite interesting to read another opinion. On www.apmag.com you can read the article after registering searching the archive for the April 2001 issue and ignoring the tons of advertising.

Have a great day
