ABSTRACT:
An apparatus for automatic loading or unloading printed circuit boards (PCBs) for semiconductor modules is disclosed. The apparatus employs an elastic jig carrier into which the PCBs are loaded. The jig carrier includes movable clamps for fixing the PCBs by elastic force. A jig opener of the apparatus applies opening force, in the reverse direction of the elastic force, to the movable clamps so that the PCBs can be loaded into or unloaded from the jig carrier by a picker. The jig carrier is transferred along a conveyor belt, while the PCBs are supplied from a PCB stage such as a tray to the jig carrier. The apparatus may further comprise a gripper and a rotator. The gripper grips the upright PCBs and the rotator rotates them to be horizontal, so that the picker can pick up the horizontal PCBs. The apparatus may also comprise an aligner for exact alignment of the PCBs in the jig carrier. A method for loading or unloading the PCBs into or from the jig carrier is also disclosed in connection with the apparatus.
