摘要： A method for mounting an integrated circuit includes a plurality of solder balls arrayed on the bottom surface of a package of the integrated circuit on a circuit board. These solder balls provide for surface mounting of the integrated circuit to a circuit board by solder reflow. The array of solder balls can be planarized so that each of the plural solder balls participate in defining a truly planar solder ball contact array for the integrated circuit package. Methods of manufacturing the integrated circuit with a package having planarized solder balls in an array dependent from a bottom surface thereof are set forth. The truly planarized solder ball contact array of the integrated circuit package affords nearly absolute reliability in forming of surface-mount electrical connections between the integrated circuit package and the circuit board on which the package is to mount.

摘要： An integrated circuit package includes a heatspreader which is formed to have a centrally disposed recessed portion between planar surfaces, and flex tape extending from the planar surfaces into the centrally disposed surface. A semiconductor chip is mounted on the centrally disposed surface between the flex tape, and wire bonds interconnect bonding pads on the chip to the metal interconnect patterns on the flex tape. Plastic molding or epoxy is then applied to encapsulate the chip and wire bonding in the centrally disposed planar surface of the heat spreader. The package is then readily mounted on a motherboard using solder balls.
