Problems solved by technology

Therefore, when the DSA is attached to and detached from the motherboard, poor fitting or poor connection may occur among the multiple connectors connected between the socket board and the motherboard.
[0020] Moreover, once such a poor connection of the connector occurs, normal testing cannot be performed, the work efficiency is reduced, and the reliability of the testing device is reduced.

Abstract

Misinstallation of a DSA to a semiconductor test instrument and connection failure of a connector are reliably detected and prevented. A semiconductor test instrument comprises a pair of DSAs (10a, 10b) on which socket boards are mounted and a mother board (20) having connectors to which connectors (14) of the socket boards (11) of the DSAs (10a, 10b) are connected. Each of the DSAs (10a, 10b) has an ID setting board for setting an ID number given to each DSA (10a, 10b) and outputting an ID signal representing the ID number, a coincidence circuit for receiving the outputted ID signal and detecting coincidence of the ID signal, a daisy chain circuit for receiving a signal from one of the connectors (21) of the mother board (20), transmitting the signal to all the connectors (21, 14) through the corresponding connectors (14) on the DSA side sequentially, and detecting an output signal.

Description

[0001] This application is a divisional application of application number 038049503 filed by the applicant, Advantest Co., Ltd., entitled "A device with a substrate abnormality detection circuit". technical field [0002] The present invention relates to a device that operates by connecting a substrate having one or two or more connectors to a corresponding counterpart substrate, such as a semiconductor testing device for testing semiconductor components. [0003] In particular, the present invention relates to a device having an abnormality detection circuit suitable for a semiconductor testing device used in combination with a plurality of DSAs equipped with a plurality of socket boards. Equipped with a comparator such as a coincidence circuit that detects whether the combination of the substrates is consistent or not by inputting an ID signal indicating the combination of the group of substrates, it is easy and accurate to detect the combination of different types of substra...
