A tin whisker is a conductive tin crystal that can spontaneously grow from tin-based lead-free finished surfaces, even at room temperature, often in a needle-like form. Oxidation in a humid atmosphere, corrosion, intermetallic formation, stress under thermal cycling, external pressure in fine-pitch connectors, and electromigration have been shown to promote whisker formation. However, acceleration models for whisker growth are very limited or nonexistent.
