Abstract: "Tin whiskers" is not an imaginative, fanciful term for some aspect of electronics manufacturing. Tin whiskers are real. Theyare microscopic conductive fibers emanating from pure tin surfaces, and they pose a serious problem to electronics of all types.These whiskers can form electrical paths, which affect the operation of the subject device. This article discusses the problemscaused by the removal of lead from electronics and describes some techniques to mitigate tin whiskers.
