Test carrier and carrier assembling apparatus

A test carrier that accommodates a device under test (DUT), the test carrier comprising:

• a carrier body that holds the DUT;
• and
• a lid member that covers the DUT and is attached to the carrier body, wherein
• the test carrier accommodating the DUT is carried to a testing apparatus comprising a socket and is mounted on the socket during a test of the DUT,
• the carrier body has
• contactors provided to correspond to terminals of the DUT,
• external terminals electrically connected to the contactors, and electrically connected to the socket while the test carrier is mounted on the socket, and
• a first through-hole through which the DUT is positioned with respect to the carrier body, and
• the first through-hole faces the DUT and penetrates the carrier body such that a part of the DUT is visible from an outside through the first through-hole by an imaging unit that captures an image of the DUT through the first through-hole.
