Tin whiskers are a physical phenomena that can occur with “pure?_ tin plating. One of the primary reasons
that lead had for decades been added to tin plating and solders in the electronics industry was to reduce
the likelihood of tin whisker growth. This is an industry-wide issue not restricted to FCI or its products.
FCI has for several years conducted extensive testing of tin plating chemistries and various techniques to
reduce to likelihood of whisker formation. In addition, we participate in industry forums and standards
organizations, such as iNEMI and IEC, where whisker test specifications continue to be developed. These industry
test methods along with additional test methods developed internally at FCI were used to qualify FCI
tin plating processes and those used by our suppliers.
FCI employs industry recognized whisker mitigation practices. However, for certain
applications where any possible whisker formation must be avoided, FCI recommends
alternative lead-free finishes, such as gold or GXT® (gold-flash over palladium-nickel alloy)
plating, which have no possibility of whisker formation.
