In one embodiment, a light emitter and a light detector are mounted on 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 integrated circuit is die-attached to an underside of the lead frame. An optically-transmissive infrared pass compound is molded over the light detector and the light emitter and portions of the lead frame. Next, an optically non-transmissive infrared cut compound is molded over the optically-transmissive infrared pass compound to provide an optical proximity sensor having no metal shield but exhibiting very low crosstalk characteristics."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical proximity sensor package with lead frame","description":"Various embodiments of an optical proximity sensor having a lead frame and no overlying metal shield are disclosed.
