Abstract

PURPOSE:To enable the check of an IC device without interruption even if a driver card/comparator card is out of order by a method wherein a spare driver card/comparator card, which is able to function in place of a regular driver card/comparator card as freely replacing it, is provided. CONSTITUTION:Usually, when an IC device 4 is checked, relays 6 and 7 in a pin selector 8 are in an ON state and an OFF state respectively. The signal from a regular driver card/comparator card 1 is given to the IC device 4 through the relay 6, a test board 2, and a measuring socket 3, and then the check of the IC device 4 is carried out. Then, when one of driver cards/ comparator cards 1 gets out of order, the relay 6 correspondent to it is put in an OFF state. The relay out of the relays 7 connected to a spare driver card/comparator card 5 correspondent to the driver card/comparator card out of order is turned in an ON state. By this setup, the spare driver card/ comparator card 5 is able to give the same signal as usual to the IC device 4 in place of the driver card/comparator card out of order.
