Abstract

See full text

An apparatus for tin whisker isolation and detection includes a substrate having a plurality of pads for connecting to an electronic component placed on the substrate, and a shield placed on a surface of the substrate. The shield includes a plurality of cavities aligned over the plurality of pads. A plurality of sensing components each associated with one of the plurality of cavities are configured for sensing an electrically conductive growth from a corresponding pad of the plurality of pads. A plurality of circuit connections are each configured to connect one of the sensing components to detection circuitry. The detection circuitry is configured to receive one or more sensing signals from one or more of the sensing components and detect an electrically conductive growth from the corresponding pad based on the one or more sensing signals.
