Hi Jack - yep, that is one of the more difficult issues with tin whisker
risk mitigation. The use of coating materials has been shown to be an
acceptable risk mitigation for the capture/containment of a tin whisker but
on connectors, the wicking issues detailed by the TechNet crew, can work
against us as a valid implementation option.
