Note(s) : Tin (Sn) whiskers are electrically conductive, single crystal eruptions that grow
from Sn film surfaces. Their high aspect ratio presents reliability problems for the
electronics industry due to bridging and metal arcing, leading to malfunctions and
catastrophic failures in many electronic systems (including satellite and defense
sectors). Due to legislation in the EU, Japan, and the U.S., mandating a gradual shift
from lead (Pb)-based to lead-free solders and board finishes, there has been a reemergence
of Sn whiskers. Continuing reports of Sn whisker induced failures coupled with the
lack of an industry-accepted understanding of whisker growth and/or test methods to
identify whisker prone products has made pure/high Sn substitutes a risky proposition
in high reliability systems. This thesis is designed to clarify and control the fundamental
mechanisms that govern whisker formation. The research focuses on reproducible "laboratory"
created whiskers under a variety of rigorously controlled environmental factors such
as film thickness, film stress, substrate material, gas environment, and humidity
exposure, which are known to play a significant role in whisker production. The ultimate
question of how to impede and/or prevent whisker growth is also addressed and shows
that whisker prevention is possible via hard metal capping films, which are impenetrable
by whiskers
