A test carrier carried in a state of accommodating a device under test (DUT) includes: a carrier body that holds the DUT; and a lid member that covers the DUT and is attached to the carrier body. The lid member includes: a plate-like main body; and a pusher protruding from the main body in a convex shape.

A testing equipment includes a tester, a load board and an adapter. The load board is disposed on the tester. The adapter is disposed on the load board and configured to support a device under test. The adapter is electrically connected to the load board and the device under test. The tester is configured to transmit a testing signal to the device under test and receive a feedback signal from the device under test through the load board and the adapter.

A measurement probe rack weight compensation system for a coordinate measurement machine may include a probe rack including rack ports for storing one or more measurement probes, the probe rack including a plurality of magnetic sensors, each configured to emit a magnetic signal in response to receipt of a magnetic field. The magnetic signal is based on a disposition of measurement probes in the rack ports. The rack ports have a plurality of positional offsets based on a plurality of disposition of measurement probes in the rack ports.

The present invention provides a test connector device for testing a component to be tested having conductive portions. The test connector device includes a base, a terminal block, and a limiting member. The terminal block is disposed on the base. The terminal block includes a substrate and terminals arranged in multiple rows and formed in an integral form with the substrate. Each of the terminals includes a first contact end and a second contact end corresponding to each other. The component to be tested is placed on the limiting member and movably assembled to one side of the base. The limiting member includes a positioning assembly and limiting slots where the first contact ends protrude out. The positioning assembly is movably fastened to the base, so that the first contact ends contact the conductive portions. Accordingly, the present invention enhances reliability, stability, and transmission efficiency during tests.

The disclosure describes a novel method and apparatus for improving silicon interposers to include test circuitry for testing stacked die mounted on the interposer. The improvement allows for the stacked die to be selectively tested by an external tester or by the test circuitry included in the interposer.

A test system (10) for testing an electric device (30), in particular a high-voltage device, has a portable main device (100) with a housing (140), an electric connection assembly (120, 121) and a mechanical connection assembly (145) and has a portable additional device (200, 300) with a separate housing (240, 340), an electric connection assembly (220, 320) and a mechanical connection assembly (245). The main device (100) can be mechanically connected to the additional device (200, 300) in a releasable manner by coupling the mechanical connection assemblies (145, 245) to form a structural unit, wherein the main device (100) can be electrically connected to the additional device (200, 300) via the first electric connection assemblies (120, 121, 220, 320).

An apparatus for telephone line testing provides a tone generator that can be remotely switched to short or open via a cable pair by monitoring shorts on the cable pair itself to allow a simplified testing protocol with reduced technician travel and without the need for a remote controller carried by the technician.

A method of testing an integrated circuit of a device is described. Air is allowed through a fluid line to modify size of a volume defined between the first and second components of an actuator to move a contactor support structure relative to the apparatus and urge terminals on the contactor support structure against contacts on the device. Air is automatically released from the fluid line through a pressure relief valve when pressure of the air in the fluid line reaches a predetermined value. The holder is moved relative to the apparatus frame to disengage the terminals from the contacts while maintaining the first and second components of the actuator in a substantially stationary relationship with one another. A connecting arrangement is provided including first and second connecting pieces with complementary interengaging formations that restricts movement of the contactor substrate relative to the distribution board substrate in a tangential direction.
