    Abstract: A central test facility transmits wirelessly test data to a local test facility, which tests electronic devices using the test data. The local test facility transmits wirelessly response data generated by the electronic devices back to the central test facility, which analyzes the response data to determine which electronic devices passed the testing. The central test facility may provide the results of the testing to other entities, such as a design facility where the electronic devices were designed or a manufacturing facility where the electronic devices where manufactured. The central test facility may accept requests for test resources from any of a number of local test facilities, schedule test times corresponding to each test request, and at a scheduled test time, wirelessly transmits test data to a corresponding local test facility.

    Abstract: A series of pulses may be driven down each drive channel, which creates a series of composite pulses at the output of the buffer. Each composite pulse is a composition of the individual pulses driven down the drive channels. Timing offsets associated with the drive channels may be adjusted until the individual pulses of the composite pulse align or closely align. Those timing offsets calibrate and/or deskew the drive channels, compensating for differences in the propagation delays through the drive channels. The composite pulse may be feed back to the tester through compare channels, and offsets associated with compare signals for each compare channel may be aligned to the composite pulse, which calibrates and/or deskews the compare channels.

    Abstract: A probe card assembly can include a probe head assembly having probes for contacting an electronic device to be tested. The probe head assembly can be electrically connected to a wiring substrate and mechanically attached to a stiffener plate. The wiring substrate can provide electrical connections to a testing apparatus, and the stiffener plate can provide structure for attaching the probe card assembly to the testing apparatus. The stiffener plate can have a greater mechanical strength than the wiring substrate and can be less susceptible to thermally induced movement than the wiring substrate. The wiring substrate may be attached to the stiffener plate at a central location of the wiring substrate. Space may be provided at other locations where the wiring substrate is attached to the stiffener plate so that the wiring substrate can expand and contract with respect to the stiffener plate.

    Abstract: Resistances of signal paths within a interconnect structure for linking input/output (I/O) ports of an integrated circuit (IC) tester to test points of an IC are measured by the IC tester itself. To do so the interconnect structure is used to link the tester's I/O ports to a similar arrangement of test points linked to one another through conductors. Drivers within the tester, which normally transmit digital test signals to IC test points via the I/O ports when the IC is under test, are modified so that they may also either transmit a constant current through the I/O ports or link the I/O ports to ground or other reference potential. The tester then transmits known currents though the signal paths interconnecting the tester's I/O ports. Existing comparators within the tester normally used to monitor the state of an IC's digital output signals are employed to measure voltage drops between the I/O ports, thereby to provide data from which resistance of signal paths within the interconnect structure may be computed.

    Abstract: A base controller disposed in a test cassette receives test data for testing a plurality of electronic devices. The base controller wirelessly transmits the test data to a plurality of wireless test control chips, which write the test data to each of the electronic devices. The wireless test control chips then read response data generated by the electronic devices, and the wireless test control chips wirelessly transmit the response data to the base controller.
