    摘要: A method and apparatus are provided for implementing direct attenuation loss measurement in an electronic package. A sinusoidal voltage source signal of a selected frequency is coupled to an embedded transmission line test structure in the electronic package. Receive circuitry is coupled to the transmission line test structure for detecting amplitude of a received sinusoidal voltage source signal to identify attenuation loss through the transmission line test structure. An identified attenuation loss of the transmission line test structure is compared with a threshold value for verifying acceptable attenuation of the electronic package transmission line test structure.

    摘要: A method and apparatus are provided for implementing automated electronic package transmission line characteristic impedance verification. A sinusoidal voltage source is coupled to a transmission line test structure for generating a selected frequency. Impedance measuring circuitry is coupled to the transmission line test structure for measuring an input impedance with an open-circuit termination and a short-circuit termination. Characteristic impedance calculation circuitry is coupled to the impedance measuring circuitry receiving the input impedance measured values for the open-circuit termination and the short-circuit termination for calculating characteristic impedance. Logic circuitry is coupled to the characteristic impedance calculation circuitry for comparing the calculated characteristic impedance with threshold values for verifying acceptable electronic package transmission line characteristic impedance.

    摘要: A method and structure are provided for implementing a column attach coupled noise suppressor for a solder column structure of the type used to join a substrate to a circuit card. The electrical noise suppressor structure includes a plurality of elongated through openings that are arranged in a predefined pattern. The elongated through openings have electrically conductive sidewalls and are electrically connected together. The predefined pattern of the elongated, electrically conductive through openings corresponds to a layout of solder columns. The solder columns are attached at one end to either a substrate or a circuit card and are inserted through the elongated through openings of the electrical noise suppressor structure, spaced apart from the electrically conductive sidewalls. Then the solder columns are attached at the other end to the other one of the substrate or circuit card.
