Pb free Finish coatings and solder can cause all kinds of issues even right out of the box. whiskers can grow in a matter of days. What ever your thoughts are on this issue it makes for some very interesting reading. Reliability will be reduced in Pb free electronics until a solution comes along. After 60yrs of study the mechanism is still not known. Manufacturers are going to down play this as they have no choice in the matter. Page 41
