Latest Patents

One of Andrews' latest patents is an IC package with a heat sink and minimal cross-sectional area. This invention discloses an IC package designed to connect one set of nodes on an IC chip to another corresponding set of nodes on a circuit board. Each interconnection is made with a single C-shaped lead, which is bonded at one end to a node on the chip. These leads extend outward from the periphery of the chip's surface, then perpendicular to and away from the chip's surface, and then inwards towards each other. A heat sink attaches to the back of the chip, and the chip, an adjacent portion of the heat sink, and the outward extending portion of the leads are encapsulated with a solid mass to hold them rigidly in place.

Another significant patent is for a chip carrier, which is an improved design of a thin dielectric deformed into a dish configuration. This chip carrier is provided with flexible mounting flanges on which are plated or bonded solderable conductive traces and paths, along with plated or bonded heat sinks that may be referenced to ground potential. This design enhances structural integrity and functionality.
