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

A load board to which a socket is mounted is electrically connected to a tester. The load board includes a first optical communication unit capable of transmitting and/or receiving signals by optical wireless communication with an electronic component handling apparatus that presses a DUT against the socket.
