Abstract:
A test carrier for an unpackaged semiconductor chip, the carrier comprising:a body having a cavity in it for receiving the unpackaged chip:contact terminals, including inner contact elements and outer contact elements, disposed on the body, the inner contact elements being disposed on a floor of the cavity to make contact with selected ones of connection pads on the chip, the outer contact elements being disposed on an outer surface of the body and electrically connected to the inner contact elements, the body and the outer contact elements being configured to engagingly mate with a test socket into which the carrier is inserted, said test socket being adapted to receive a conventionally packaged chip; and,means for holding the chip in the cavity such that the inner contact elements are in electrical contact with the selected ones of the connection pads on the chip, said means for holding the chip in the cavity comprising:a clamp rotatable disposed on the body for rotation into and out of the cavity the clamp having a jaw extending into the cavity, a tail extending out of the cavity, and an arm connecting the jaw to the tail such that a force exerted on the tail rotates the jaw of the clamp up and away from the floor of the cavity; and,means for rotatable biasing the jaw of the clamp down and toward the floor of the cavity.
