Abstract: A switch control apparatus for controlling a switch is provided, the switch control apparatus including: a sequence memory for recording a sequence pattern, which includes open/close instruction data which instruct the switch thereon to open/close; an address control module for sequentially retrieving each of the open/close instruction data of the sequence pattern from the sequence memory; and an open/close state storage module for storing an open/close state instructed by changed open/close instruction data, when the open/close instruction data retrieved by the address control module is changed, wherein the open/close state stored by the open/close state storage module is provided to the switch such that the switch opens or closes in response to the open/close state.

Abstract: A semiconductor test system includes a semiconductor test apparatus for providing a test signal to a device under test and performing a test on the device under test, a performance board for electrically coupling the semiconductor test apparatus and the device under test and a conveyance apparatus for conveying the device under test to electrically couple the device under test to the performance board. The conveyance apparatus includes a box for containing the performance board therein and a conveyance arm for conveying the device under test in order to press the device under test to the performance board and pressing the performance board to an inner face of the box via the device under test, so that a rear face of the performance board is pressed to the box, wherein the rear face corresponds to a position to which the device under test is pressed.
