. Lead hot air solder leveling, or HASL, used to be one of only two ways that printed circuit boards could be finished. Now, dozens of options are available with affordable prices, good handling sensitivity, and long-lasting shelf life

) to prevent such failures. Such techniques are now fairly common for lead-free assemblies [7]. Without getting into great detail, it can be said that in the course of this extensive two year effort many lead-free issues were discovered and each was resolved prior to launching of the consumer lead-free products
