Preliminary Guidance for Optical Inspection for Metal Whiskers

December 2008:  Whisker Growth Videos by CALCE (University of Maryland)

April 2007:  Tin Plasma Formation (Metal Vapor Arc) by The Aerospace Corporation

The following videos have been produced by component engineers from the NASA Goddard Space Flight Center and the NASA Shuttle Logistics Depot to document various aspects of metal (e.g., tin and zinc) whiskers.  

Video # Subject Production Date Description
11 Zinc Whiskers on Hot Dip Galvanized (HDG) Steel and Whisker Bending Due to Electrostatic Attraction September 2007 Video illustrates HDG coatings are not immune to whisker formation.  Also illustrates bending/flexing of whiskers in presence of electric fields

Tin Whisker Motion Due to Gentle Air Currents

RealPlayer Format (2.5 MBytes)
MPG Format (26 MBytes)
 Nov. 5, 2002 Demonstrates how some tin whiskers behave under influence of minor air currents.  These whiskers were found growing inside of electromagnetic relays whose procurement specs prohibited the use of pure tin-plating, but the finish WAS PURE TIN nevertheless.

Recommendations for viewing these videos are as follows:

RealPlayerTM software is recommended for viewing "RealPlayer" file formats.  Free download is available.
Select "full screen" viewing option from the software you are using
Some of these video files are very large. If your internet connection speed is slow, it is suggested to download the file to your hard drive and then view the saved file rather than view as an internet streaming video.
Note:  The quality of the video image may depend on the video graphics capabilities of your computer

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.
