Tin and Other Metal Whisker Anecdotes

This portion of the NASA Goddard Metal Whisker WWW Site is intended to collect Whisker Anecdotes where more "formal" publicity of the item is either unavailable or "unwanted" by the individuals/organizations experiencing the problems. Attempts have been made to gather and report the information in as detailed a manner as possible while protecting the sensitivity/anonymity of the parties involved.

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.
