  • Signal sensing device and circuit boards
    Patent number: 9234915
    Abstract: Apparatus are provided for use in testing circuit boards. A signal sensing device includes one or more probes. Each probe includes a length of rigid coaxial conductor configured to define a sensing pin at one end. A circuit board defines a number of through vias lined in metal and configured to receive the sensing pin of a corresponding probe. The signal sensing device also includes a ground pin. Electrical pathways extending away from adjacent pairs of the through vias can be tested for electrical impedance and other signal propagating characteristics by way of the signal sensing device.
    Type: Grant
