Abstract:
A probe card adapted for testing at least one integrated circuit integrated on corresponding at least one die of a semiconductor material wafer, the probe card including a board adapted for the coupling to a tester apparatus, and a plurality of probes coupled to the said board, wherein the probe card comprises a plurality of replaceable elementary units, each one comprising at least one of said probes for contacting externally-accessible terminals of an integrated circuit under test, the plurality of replaceable elementary units being arranged so as to correspond to an arrangement of at least one die on the semiconductor material wafer containing integrated circuits to be tested.
Abstract:
A monitoring device is for at least one physical characteristic of a building material. the monitoring device is buried inside a block of the building material and has a sensor to sense a physical characteristic thereof. The monitoring device includes a secondary inductor and a circuit coupled thereto, the circuit to generate an internal supply voltage for the sensor to transmit a signal representative of the physical characteristic. A wireless power supplier for the sensor is configured to generate a variable electromagnetic field, and has a dielectric layer and a resonant L-C circuit buried therein. The resonant L-C circuit has a primary inductor to be magnetically coupled to the secondary inductor of the sensor, with the wireless power supplier further having two current terminals being coupleable to an external reading circuit for the signal. The sensor is adjacent to the dielectric layer so as to magnetically couple the primary inductor and the secondary inductor.
