Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for clarifying a classification identification of a stocker in which ICs under test are classified and stored after an electric test by an IC test handler.

[0002]

2. Description of the Related Art A category classification system by a device transport mechanism in a conventional IC test handler for trays will be described with reference to FIGS. The configuration of the IC test handler is as shown in FIG.
A test chamber section 23, an unloader section 12,
It is composed of a soak chamber 15 and an EXIT chamber 16.

As shown in FIG. 3, ICs (devices to be measured) 29 are mounted on the customer tray 30 in units of a plurality. A plurality of the customer trays 30 are stacked and mounted on the loader stocker unit 19. The stocker of the loader stocker section 19 is fastened or held by a drawer section provided with a slide mechanism 28, and
After mounting the tray 30, it is stored in the main body. Customer ·
The tray 30 is set in the tray setting section 22 of the loader section 10 by the transfer mechanism of the transfer arm 17.

The IC 29 is an adsorption / loader for the loader kit 11.
Opening the customer tray 30 to the test tray 1
4 and after being transferred to the test chamber section 23 at the bottom via the preheating soak chamber 15,
The test is run. Tested IC29 is EX for heat removal
Transferred to the unloader unit 12 via the IT chamber 16,
By the suction / release operation of the unloader kit 13, the test tray 14 is repeatedly transferred to the customer tray 30. At this time, the IC 29 is mounted on the customer tray 30 of a predetermined category by the selective operation of the unloader kit 13 based on the category of the test result.
This tray has a stocker unit 21 for empty trays if necessary.
Then, the transfer arm 17 is set on the tray setting section 22 of the unloader section 12.

Subsequently, the IC mounted tray is gripped by the transfer arm 17 and horizontally moved, so that the tray is selectively sorted into a predetermined category of stockers of the unloader stocker section 20 of the stocker storage section 27, as shown in FIG. It is stored. Here, the category refers to a classification number and a classification code for classifying devices according to quality judgment and characteristic rank according to test results. The categories of each stocker in the stocker storage section 27 are the categories of the front side 24 of the handler.
The category number is displayed on the category display portion 25 of the panel 26, and the category of the IC in the stored tray can be confirmed.

[0006]

As described above, the category of the tested IC is confirmed by confirming the category display portion 25 on the front surface 24 of the handler, and after taking out from the handler main body, the category of each tray is checked. Identification will rely on the operator's memory. This is not preferable because there is a possibility that a classification error such as mixing may occur during handling work after taking out from the handler body. Therefore, the problem to be solved by the present invention is to reliably identify the trays of the tested ICs by category to prevent troubles caused by moving and handling.

[0007]

In order to solve the above-mentioned problems, in the structure of the present invention, the side surface of the tray cassette 33 is I-shaped.
A box-shaped structure is provided in which a category identification indicator 34 indicating the C classification is attached, and the customer trays 30 are stacked and supported from the upper side of the tray cassette 33.・ Tray cassette 33 to be mounted on the IC sorting mechanism of the handler
Is provided. As a result, by using the customer tray 30 on which the IC to be tested is mounted, the category identification display of the customer tray 30 classified by the test result of the IC test handler and the storage structure for stably storing the customer tray 30 are realized.

[0008]

The tray cassette 33 is provided with an IC category identification indicator 34 on its side surface and a predetermined category number tag is attached to the tray cassette 33, so that the customer tray 3 after the classification is sorted.
It is a function to prevent troubles caused by moving and handling 0. In addition, the tray cassette 33 has a function of accommodating the multi-tiered customer trays 30 in a stable state.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An example of the present invention will be described with reference to FIG. As shown in FIG. 1, the tray cassette 33 has an open frame structure, and has a shape that allows the customer trays 30 stacked from the top to be taken in and out and the number of trays therein to be confirmed. On the bottom surface, the attachment part 35 with the stocker 31
And the opening 3 for the elevator for raising and lowering the tray to pass through.
6 is provided. A category identification display 34 is provided on the front surface or at a place where the information can be confirmed from the outside to display identification information. For example, the category of the stored IC 29 in the tray is displayed or written. A handle 32 for transportation is provided on this side surface. By configuring the tray cassette 33 as described above, it is possible to provide a display portion for the IC category identification information, and the display content can be freely expressed. Further, unlike the conventional case, the tray is not in an unstable state in which the trays are stacked, but is stably stored in the tray cassette 33, which facilitates transportation and handling.

In the above description of the embodiment, the case where the IC test handler is used is explained, but other ICs are used.
It can be similarly applied to a lead bending tester, an IC marking device and the like.

[0011]

Since the present invention is configured as described above, it has the following effects. By providing the tray cassette 33, providing the IC category identification indicator 34 on this side, and attaching a predetermined category number tag, it is possible to prevent troubles caused by moving and handling the customer tray 30 after classification. To be Further, the tray cassette 33 allows the customer tray 30 to be stored in a stable state, which facilitates transportation and handling.
