Method and apparatus for reducing the occurrence of metal whiskers on surfaces are disclosed herein. In particular, the present disclosure teaches providing at least one source of electromagnetic energy to emit energy to reduce the occurrence of metal whiskers on a surface. Mature (i.e. larger) whiskers are mitigated by lower frequency EM energy, such as millimeter waves and THz RF waves, and the method benefits from the electric field enhancements at the tips of such structures. Immature (i.e. smaller) whiskers are mitigated by higher frequency EM energy, such as infrared, optical, and ultraviolet frequencies. The mitigation is in the form of very localized surface heating, sufficient to overcome driving internal stresses, and in the form of disruption of coherent electrical potential basis present in the material. |
