Abstract

A method and an apparatus for mitigating electrical failures caused by intrusive structures. Such structures can be tin whiskers forming on electrical circuits. In an illustrative embodiment, nano-capsules are filled with some type of insulative and adhesive fluid that is adapted to bind to and coat an intrusive structure, e.g., a whisker, making the whisker electrically inactive and thereby reducing the electrical faults that can be caused by the whisker. In another illustrative embodiment, randomly oriented nano-fibers having an elastic modulus higher than tin or any other whisker material is used to arrest a growth or movement of a whisker and further reduce a likelihood that a whisker can cause an electrical fault.
