    摘要: A thermally enhanced semiconductor package includes a sheet metal cap having flexible flanges provided with solder contacts for reliable attachment to a circuit board. The package assembly further includes a semiconductor chip with a contact-bearing front surface facing forwardly, and chip bonding contacts overlying the front face of the chip. The flange bonding contacts are coplanar with the chip bonding contacts, or can be brought into coplanar alignment by flexure of the cap. The package can be surface-mounted to a circuit board by placing the package onto pads of solder paste, and then heating the assembly to melt the solder paste in order to join the bonding contacts on the chip and on the flange to corresponding contacts on the circuit board.

    摘要: A method of making a semiconductor chip assembly, including providing a dielectric element with a plurality of electrically conductive terminals, disposing an expander ring over the dielectric element so that a semiconductor chip on the dielectric layer is disposed in a central opening in the expander ring, and disposing an encapsulant in the gap between the expander ring and the semiconductor chip. The size of the gap is controlled to minimize the pressure exerted on the leads by the elastomer as it expands and contracts in response to changes in temperature. The semiconductor chip and expander ring may also be connected to a heat sink or thermal spreader with a compliant adhesive.
