    摘要: A method of electrically qualifying high speed printed circuit board (PCB) connectors includes mounting a PCB connector on a test card, sending bit patterns through a first portion of the test card, evaluating a waveform on a sense signal on a second portion of the test card for the bit patterns launched on said first portion of the test card to measure common mode noise, and comparing the measured common mode noise of the second portion of the test card to a golden standard performed on a pre-qualified connector. The first portion of the test card comprises connectors to inject bit patterns. The second portion of the test card includes a split plane which induces common mode noise on a sense signal, the sense signal, and a termination pack. If the measured common mode noise on the PCB connector is worse than the golden standard, then the PCB connector is disqualified. If the measured common mode noise on the PCB connector is as good as or better than the golden standard, then the PCB connector is qualified. A first section of the PCB connector connects to the first portion of the test card and a second section of the PCB connector connects to the second portion of the test card. Transmission lines in the test card and the sense line are tightly coupled by shortening a distance between the sense line and the transmission lines.

    摘要: A cable having an electrically conducting wire with a cross sectional shape defined by a simple closed curve having from three to eight concave portions separated by an equal number of convex portions. The simple closed curve has no point where the radius of curvature is less than one-sixth (⅙) of an overall radius of the wire and no point where adjacent curves or lines intersect at an angle. The alternating concave and convex portions of the cable's cross-sectional shape may have substantially the same curvature. The cross-sectional shape of the cable avoids sharp angles and fight curves.

    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.
