Multifunctional Platelet Composites for Tin Whisker Mitigation
The present invention relates to composite coatings including particles embedded in a matrix, as well as methods and uses thereof. In some examples, the particles are aligned to enhance mitigation of whisker formation from an underlying metal material. Such coatings can be applied to electrical components, thereby reducing the possibility of electrical short circuits from aberrant whisker growth.
