Abstract

PURPOSE:To shorten the indexing time by providing the following: a plurality of contactors; and a circuit used to select which interconnection from a tester is to be connected to the contactors. CONSTITUTION:A tester 4 is connected to a contactor 1 by using a selection circuit 3. While a package 5 is being measured by using the contactor 1, a package 6 whose measuring operation has been finished by using a contactor 2 is discharged. A package 7 to be measured next is fed and on stanby. When the measuring operation of the package 5 has been finished, the selection circuit 3 is changed over. The measuring operation of the package 7 is started, and the contactor 1 alternately repeats its operation in such a way that the package 5 is replaced with a package 8 which has not been measured yet. Thereby, the time required to replace a package until a next measuring operation is started from the finish of a measuring operation is not required, the indexing time can be shortened, and the number of measuring operations per unit time can be increased.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to handlers.

[Summary of the Invention] The present invention provides, in a handler, ? By providing l rQ conductors and preparing a circuit for selecting which conductor the wiring from the tester is connected to, the index time can be significantly shortened.

[Prior art 1] Conventionally, as shown in FIG. 2, one conductor 1 discharges the package 3 after completing the measurement of the package 3, supplies the next package 4 to be measured, and then Next, the measurement of Parapoppy 4 to be measured is started.

[Problems to be Solved by the Invention] However, the conventional fat technology has the disadvantage that it takes l time to replace the package between the end of measurement 1' and the start of the next measurement. As a result, problems such as a low rate of 1 ill per unit time were caused.

[Means for solving the problem] In order to solve the above-mentioned problems, the present invention provides a multi-H conductor and uses a circuit to select which conductor the tester's wiring is connected to. According to the above configuration, while measuring with one conductor, in the next conductor, the package which has already been measured is replaced with the package to be measured next.
The next measurement can be started by leaving the conductor on standby and switching the selection circuit to the next conductor when the measurement is completed.
This eliminates the time required to replace packages, and the time from the end of a measurement to the start of the next measurement can be significantly shortened.

[Example 1 Embodiments of the handler of the present invention will be described based on the drawings.

FIG. 1 is a basic configuration diagram showing the connection between one embodiment of the handler of the present invention and a tester. The selection circuit 3 connects the test 4 and the conductor 1, and while the conductor 1 is measuring the package 5, the package 6 which has already been measured is discharged from the conductor 2, and the package 7 to be measured next is supplied. and wait. When the measurement of the package 5 is completed, the selection circuit 3 switches to 2.
The measurement of the package 7 is started, and the conductor 1 replaces the package 5 with the unmeasured package 8, and so on, and repeats the operation alternately.

As another example, it may be possible to further increase the number of conductors to cope with the case where the measurement time is short.

[Effect of the invention 1] As explained above, the present invention eliminates the time required for changing packages between the end of a measurement and the start of the next measurement, and only the time required for switching the selection circuit.・It has the effect of significantly shortening the time and at the same time increasing the number of measurements per unit time.
