An IC receiving tray storage device is provided which is capable of securedly identifying the category of the tested ICs sorted for each category and received in the corresponding tray in the unloader section after end of test. Mounted to the tray storage is a casing comprising a generally rectangular base plate and a plurality of outer walls standing substantially upright and separately from each other on the base plate. A category identifying indicator is attached to at least one outer wall of the casing. This category identifying indicator indicates the category of ICs received in the tray. Also, in the base plate of the casing is formed an opening through which vertically movable unit is free to move. By the category identifying indicator, the category of the tested ICs received in the tray can be easily confirmed after the tray storage device has been taken out from the IC handler.

IC receiving tray storage device and mounting apparatus for the same

Latches are pivotally provided on opposite sides of an IC device stored in the pocked of an IC carrier. Connecting arms of the latches are engaged in engagement holes formed in actuator members which are biased upwardly by springs. The top surface of the IC carrier, except the IC pocket, is covered by an actuating plate. The positioning pins of an IC set/removal mechanism are inserted into holes of the IC carrier so as to cause the mounting plate to which the pins are secured to press the actuating plate down against the top face of the IC carrier causing the actuator members to pivot the latches, whereby the hold-down lugs of the latches are retracted from the top of the IC. The IC is now ready to be picked up by a suction pad.
