WebA “tin whisker” is a single crystal of tin that grows spontaneously from the plated surface. Manufacturers who prefer the use of tin over lead plating can encounter problems with their interconnections. As “tin whiskers” grow, they can cause electrical shorts, and/or can flake off, causing physical damage. “Tin Whiskers” are ... Web1 de dez. de 2015 · This paper presents experimental results supporting a theory that electric fields accelerate the growth of tin (Sn) whiskers. We have rapidly (within one week) grown long (≈100 urn) and dense (≈300 mrrr2) whiskers on thin Sn films. Humidity and an applied electric field are found to have a strong effect when applied together, making … birdhouse runs osrs
