Abstract

PURPOSE:To eliminate the need to refer to a test program name corresponding to the lot name of a body to be tested by an operator by reading the lot name and type name of the body to be tested and referring to the corresponding test program name on the basis of the lot name, etc., by a host computer. CONSTITUTION:The host computer 1 refers to a type and test program correspondence table 9 set previously in a storage device 2 and reads the corresponding test program to generate a lot name and test program name correspondence table 8. When a lot name is read by a reader 5 during the testing operation of a lot to be tested, a testing device 3 transmits the lot name to the computer 1 through a network. The computer 1 refers to the correspondence table 8 to read the test program name and sends out the corresponding test program stored in the device 2 to the device 3 through the network. Then, the sent test program is stored 7. Therefore, when the test program is set in the device 3, the operator need not refer to the corresponding test program on the basis of the lot name and type name and it is referred by the machine.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an inspection system comprising a test device and the like for testing semiconductor integrated circuits and the like.

[Conventional technology]

Generally, when testing semiconductor integrated circuits, etc., a test program that describes test conditions, etc. is prepared and set in a test device before testing.

Conventionally, in this type of inspection system, the test program was transferred from a connected host computer by inputting the test program name from the terminal device of the test device. An example is shown in FIG. In FIG. 2, 1 is a host computer, 2 is a storage device, 3 is a test device, 4 is a terminal device, and 7 is a storage device for storing test programs.

To set the test program in the test device, enter the test program name on the terminal device 4, and the test program name is sent to the host computer via the test device 3 and the connection line, that is, the network. By reading the test program compatible with IH from the storage device 2 and sending it to the test device 3 via the network, the test program is stored in the storage device 7 in the test device.
It was stored in.

[Problem that the invention seeks to solve]

Generally, the test object is made up of rods and given a name or number, that is, a rod name, but in conventional inspection systems, when setting a test program in the test equipment,
There was a drawback that the operator had to refer to the corresponding test program name from the rod salt or model name.

The present invention solves the above problems and provides an inspection system that mechanically refers to a test program.

[Means for solving problems]

The inspection system of the present invention includes a host computer and a test device connected to the host computer via a network, and includes means for inputting or reading the rod salt or model name of the object to be tested, and a means for inputting or reading the rod salt or model name of the test object. The present invention is characterized by comprising means for referring to a corresponding test program name from the host computer, and means for transmitting the test program corresponding to the test program name from the host computer to the test apparatus.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention, in which 1 is a host computer, 2 is a storage device, 3 is a test device, and 4 is a terminal device. Further, 5 is a reading device, 6 is a terminal device of the host computer 1, 8 is a rod salt/test program name correspondence table, and 9 is a model name/test program name correspondence table.

In the example, the operation of setting the test program in the test device 3 is as follows: When the rod to be tested is put into production, the rod salt and model name are specified from the terminal device 6 of the host computer 1. Then, the host computer 1 refers to a model name/test program name correspondence table 9 set in advance in the storage device 2, reads the corresponding test program name, and creates a rod salt/test program name correspondence table 8. When testing the rod under test, the reading device 5 reads a magnetic card or barcode on which the rod under test information is recorded, and the rod salt is read.
The test device 3 transmits the rod salt to the host computer 1 via the network. The host computer 1 refers to the rod/name test program name correspondence table 8, reads the test program name, and sends the corresponding test program stored in the storage device 2 to the test device 3 via the network.
Send to. The test/inspection device 3 stores the sent test program in the storage device 7.

Naturally, the model name of the rod under test may be read by the reader 5, and in this case, it is possible to omit creating a rod salt/test program correspondence table in the host computer 1. It is also possible to input the rod salt or model name from the terminal device 4 without using the terminal 5.

〔Effect of the invention〕

As explained above, according to the present invention, it is no longer necessary for the operator to refer to the test program name of the rod under test.
This has the effect of simplifying the work.
