An electronic component testing apparatus for testing a device under test (DUT) includes: a socket unit that is electrically connected to the DUT; a first wiring board that includes a board opening; and a tester that includes a test head in which the first wiring board is mounted. The socket unit includes a first socket that faces a first main surface of the DUT and is electrically connected to the DUT and the first wiring board. The second socket that is exposed from the first wiring board through the board opening, contacts a second main surface of the DUT on a side opposite to the first main surface, and includes: a base that contacts the second main surface; and a test antenna unit that is electrically connected to the tester and faces a device antenna unit of the DUT.

Electronic component testing apparatus, sockets, and replacement parts for electronic component testing apparatus

An electronic component testing apparatus is used for testing a device under test (DUT). The electronic component testing apparatus includes: a socket unit that is electrically connected to the DUT; a first wiring board; and a tester that comprises a test head in which the first wiring board is mounted. The socket unit includes a first socket and a second socket. The second socket includes a base and a test antenna unit. The tester tests the DUT by transmitting and receiving radio waves between a device antenna unit of the DUT and the test antenna unit while the DUT is electrically connected to the first socket and the first socket is electrically connected to the test head through the second socket.

An electronic component handling apparatus includes: a moving device that moves a device under test (DUT) including a first antenna and presses the DUT against a socket. The moving device includes a holder that holds the DUT and a second antenna that receives a radio wave radiated from the first antenna or that radiates the radio wave to the first antenna.

Electronic component handling apparatus, electronic component testing apparatus, and socket

The socketcomprises a first contact probewhich has a first end which is to contact with a first terminalof the DUT, a second contact probewhich has a second end which is to contact with a second terminalof the DUT, and an inner housingwhich holds the first and second contact probesso that the first end and the second end are located on substantially the same virtual plane VP, and the length Lof the second contact probeis shorter than the length Lof the first contact probe. The interposercomprises a substratewhich has a through holeinto which the first contact probeis to be inserted, and a wiring patternwhich is disposed on the substrate, and the wiring patternhas a padwith which the second contact probeis to contact.

Interposer, socket, socket assembly, and wiring board assembly

An electronic component presser is included in an electronic component testing apparatus used to test a device under test (DUT). The electronic component testing apparatus includes an electronic component handler, an electronic component tester, and a first socket. The electronic component presser connects to the electronic component handler and to the electronic component tester. The electronic component presser includes: a holding plate that holds the DUT that has been carried to the holding plate by a contact arm of the electronic component handler; a transport unit that moves the DUT between the holding plate and the first socket; a pusher that presses the DUT that has been disposed on the first socket; and an antenna unit comprising a measurement antenna that faces a device antenna of the DUT disposed on the first socket.

Electronic component pressing apparatus and electronic component testing apparatus

An electronic component handling apparatus includes: a thermostatic chamber in which a socket disposed, the socket electrically being connectable to a device under test (DUT) including a first antenna; a moving device that moves the DUT and presses the DUT against the socket; an anechoic chamber disposed adjacent to the thermostatic chamber; a second antenna disposed inside the thermostatic chamber; and a first window that transmits radio waves radiated from the first or second antenna. The thermostatic chamber has a first opening on a wall surface of the thermostatic chamber. The anechoic chamber has a radio wave absorber and a second opening that opens toward a transmission direction of the radio waves from or to the second antenna. The thermostatic chamber and the anechoic chamber are connected to each other to make the first opening and the second opening face each other.
