Whiskers
How much do all you experts know about whiskers on electronic circuitry?
This is not a joke. If any want to know? Ask. |

Terhune & Brian K. were talking about that very recently! -- Thanks or Good Luck, There may be humor in this post, and, Naturally, you will not sue, should things get worse after this, PCR "poatt" wrote in message ... | How much do all you experts know about whiskers on electronic circuitry? | This is not a joke. | If any want to know?

Maybe poatt was referring to a crystal detector?

Or tiny filaments that sometimes develop on the surface of electronic circuits coated with tin or zinc. The filaments sometimes cause failures in the elctronics when they form shorts between conductors. Appears to have affected satilites, at least two models of missles, fighter jet radar and reactor monitoring equipment (false low coolant pressure "reading" shut a reactor down). Apparently a problem with SOME floor tiles used with the raised floors in some data centers too. The whiskers form on the zinc plated bottom of the tiles, get knocked off, are blown around by the air conditioning and short the equipment out. http://nepp.nasa.gov/whisker/background/index.htm http://nepp.nasa.gov/whisker/failures/ |
