Abstract:
1. An optical proximity sensor package, comprising: a lead frame comprising a plurality of discrete electrically conductive elements having upper and lower surfaces, at least some of the elements not being electrically connected to one another; an infrared light emitter mounted atop an upper surface of at least a first of the plurality of discrete electrically conductive elements and electrically connected to at least a second of the plurality of discrete electrically conductive elements; a light detector mounted atop an upper surface of at least a third of the plurality of discrete electrically conductive elements and electrically connected to at least a fourth of the plurality of discrete electrically conductive elements; an integrated circuit chip mounted to a lower surface of one of the plurality of discrete electrically conductive elements and being mounted at least partially underneath at least one of the infrared light emitter and light detector, the integrated circuit chip comprising light emitter driving and light detecting circuits operably connected to the light emitter and the light detector, respectively; a first molded infrared light pass component disposed over and covering the light emitter; a second molded infrared light pass component disposed over and covering the light detector, and a molded infrared light cut component disposed over and between the first and second molded infrared light pass components and over portions of the plurality of discrete electrically conductive elements, the molded infrared light cut component having first and second apertures disposed therethrough above the light emitter and the light detector, respectively; wherein each of the plurality of discrete electrically conductive elements comprises an outer end extending outwardly from the molded infrared light cut component to form an electrical contact of the package.
