Carrier module including a carrier module body for seating a semiconductor device on an underside thereof, having a pass through hole from an upper part to the underside the semiconductor device is seated thereon, a housing over the carrier module body, a supplementary housing fitted in a lower part of the housing to be movable in up/down directions, for elastic contact with the carrier module body by a first elastic member fitted inside of the housing, a vacuum tube in the supplementary housing so as to be in communication with the pass through hole in the carrier module body, at least one pair of latches in a lower part of the carrier module body to move apart or close in an outer or inner side, for holding or releasing the semiconductor device seated on the carrier module body, a latch button fitted in an upper part of the carrier module body so as to be movable in up/down directions, and coupled to the latch with a connection pin for moving in up/down directions by an external force, to making the latch to move, and a second elastic member for elastic supporting of the latch buttons on the carrier module body, thereby, when the semiconductor device is brought into contact with the test socket, and tested, holding the semiconductor device with a vacuum formed through the pass through hole in the carrier module body and the vacuum tube in a state the latch releases the semiconductor device.

Carrier module

Carrier module for a semiconductor device test handler including a carrier module body, a device seating part in an underside part of the carrier module body, at least one pair of first latches at opposite sides of the device seating part arranged opposite to, and movable away from, or close to, each other, for holding, or releasing opposite side parts of the semiconductor device seated on the device seating part, at least one pair of second latches rotatably fitted on opposite sides of the first latch, for holding an underside part of the semiconductor device seated on the device seating part, and releasing the semiconductor device interlocked with a releasing action of the first latch, a latch button fitted in an upper part of the carrier module to move in up/down directions and coupled to one end of the first latch, for moving up and down to make the first latch to move, and a first elastic member, and a second elastic member for elastic supporting of the first latch, and the second latch, thereby securely holding, transferring, and bringing the semiconductor device into contact with the test socket, for testing.

Carrier module for semiconductor device test handler

A device test handler and a method for operating the same provide a significant reduction of the picking up and placing time periods, and reduce possible damage to the devices being tested. Devices and methods embodying the invention facilitate room temperature and high temperature testing within one device test handler to maximize testing efficiency. A test handler embodying the invention may include a pre-heater for pre-heating the devices on a loading shuttle as the loading shuttle passes to a test chamber. An indexing device in a test chamber of the device is used for successively transferring the devices from a loading shuttle to the test socket, and tested devices from the test socket to an unloading shuttle. Heat supply means may be provided for supplying a high temperature heat to the test chamber when the devices are required to be tested in a hot state. An unloading part having a plurality of trays movably fitted on the base is used to transfer devices from an unloading shuttle to output trays based on the testing results.
