Raised Floor Tiles with ZINC Whiskers

The whiskers below are ZINC WHISKERS.  They were found growing on the zinc-coated steel underside of raised floor tiles.  In these examples the floor tiles were part of a computer room in which zinc whisker debris was shed from the floor tiles especially during maintenance activities within the data center .  The conductive whisker debris was distributed around the room via the air cooling system.  Ultimately, some whisker debris was drawn inside of the electronic systems (e.g., servers, routers, disk arrays) operating in the data center resulting in catastrophic and/or intermittent short circuit failures.
See the presentation:  "Zinc Whisker Awareness:  Could Zinc Whiskers Be Impacting Your Electronics?" for More about Zinc Whiskers

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.
