    摘要: Methods, apparatuses, and computer program products are disclosed for controlling plating stub reflections in a chip package. In one embodiment, a resonance optimizer determines performance characteristics of a bond wire that connects a chip to a substrate of a semiconductor chip mount. In this embodiment, the resonance optimizer selects, based on the performance characteristics of the bond wire, a line width for an open-ended plating stub that extends from a signal interconnect of the substrate to a periphery of the substrate, The resonance optimizer also generates a design of signal traces for the substrate, where the signal traces include the open-ended plating stub with the selected line width.

    摘要: Embodiments of the present invention are directed to shifting the resonant frequency in a high-frequency chip package away from an operational frequency by connecting a capacitance between an open-ended plating stub and ground. One embodiment provides a multi-layer substrate for interfacing a chip with a printed circuit board. A first outer layer provides a chip mounting location. A signal interconnect is spaced from the chip mounting location, and a signal trace extends from near the chip mounting location to the signal interconnect. A chip mounted at the chip mounting location may be connected to the signal trace by wirebonding. A plating stub extends from the signal interconnect, such as to a periphery of the substrate. A capacitor is used to capacitively couple the plating stub to a ground layer.

    摘要: Improving signal quality in a high-frequency chip package by resistively connecting an open-ended plating stub to ground. One embodiment provides a multi-layer substrate for interfacing a chip with a printed circuit board. A conductive first layer provides a chip mounting location. A signal interconnect is spaced from the chip mounting location, and a signal trace extends from near the chip mounting location to the signal interconnect. A chip mounted at the chip mounting location may be connected to the signal trace by wirebonding. A plating stub extends from the signal interconnect, such as to a periphery of the substrate. A resistor is used to resistively couple the plating stub to a ground layer.

    摘要: Packages and methods for mitigating plating stub effects. The semiconductor package includes an interposer substrate having a first side, a second side, a peripheral edge connecting the first side with the second side, a signal line on the first side, and an electrode pad on the first side. A semiconductor element is mounted on the first side of the interposer substrate. The semiconductor element is connected with the electrode pad by the signal line. A terminating resistor is mounted on the interposer substrate. A plating stub, which is located on the interposer substrate, has a first end portion that terminates near the peripheral edge of the interposer substrate and a second end portion that is electrically connected to the electrode. The first end portion is electrically connected through the terminating resistor to an electrical ground.
