Tin Whisker Growth on Lead-Free Surface Finishes
Pure tin finishes grow conductive single-crystal whiskers over months to years, bridging fine-pitch conductors and causing intermittent shorts that no functional test at delivery can find. It is the canonical demonstration that a parts and materials selection rule is a reliability control.
