Hodně dobrý je ten rozbor. Důležitá pro někoho by mohla být pasáž o RoHS...

Why the Recent Attention to Tin Whiskers?
The current worldwide initiative to reduce the use of potentially hazardous materials such as lead (Pb) is driving the electronics industry to consider alternatives to the widely used tin-lead alloys used for plating. For example, the European Union has enacted legislation known as the Restriction of certain Hazardous Substances (RoHS) and Waste Electrical and Electronic Equipment (WEEE) Directives which have set June 2006 as deadlines for electronic equipment suppliers to eliminate most uses of Pb from their products.  It is widely believed (though reasons remain somewhat of a mystery) that Pb when alloyed with tin imparts whisker-inhibiting attributes to the final finish.
