Thanks Inge. (You are working late. A by product of the Nordic affinity for strong coffee perhaps ;-) ? "Curious and curiouser", indeed. Was this a one lot of product effect or is it repeating? If has been limited to one lot, has an attempt been made to recreate the effect in some sort of designed experiment? Obviously based on the scale, the length of these whiskers are not going to be a threat equal to the threat of tin whiskers which can be more than two orders of magnitude greater in length. Nothing like a good process problem to keep the process engineers mental gears engaged.
