This section of the NASA Metal Whisker WWW Site is being constructed to provide examples of the phenomenon of metal "DENDRITE" formation.  Unfortunately, the terms "dendrites" and "whiskers" are sometimes used interchangeably.  In fact, the morphology and mechanisms of formation are distinctly different for metal whiskers and dendrites.

DISCLAIMER:
This website provides information about tin whiskers and related research. The independent research performed during the past 50+ years is so vast that it is impractical to cover all aspects of tin whiskers in this one resource. Therefore, the absence of information in this website about a particular aspect of tin whiskers should NOT be construed as evidence of absence.
