[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a semiconductor burn-in device, and more particularly, to a burn-in board insertion / extraction device.

[0002]

2. Description of the Related Art Conventionally, a burn-in test has been performed in a constant temperature bath maintained at a constant temperature. An example of a thermostat used for this is shown in FIGS.
4 is a side view, FIG. 5 is a front view (with the door omitted), and FIG. 6 is a BB cross-sectional view (including the door) of FIG. This thermostat comprises a main body 1, a door 2 and a rear door 3.

Such a thermostat has a board rack 4 as shown in FIGS. 9, 10 and 11 inserted therein as shown in the structure diagram of the conventional thermostat in FIGS. The feedthrough board 5 is inserted and fixed at regular intervals, and is connected to an external power source and signal source 6 by connecting the outer edge connector 5a and the cable connector 8a of the cable 8. 7 is a side sectional view, and FIG. 8 is a rear view.

The above-mentioned board rack 4 is shown in FIG.
0 As shown in the front view and FIG. 11 board mounting explanatory view, the bars 4a are fixed in parallel on the side surface at fixed intervals, and the burn-in board 7 is inserted between the left and right bars 4a, 4a. ing.

The burn-in board 7 is provided at one end of the printed board 7a, a reinforcing frame 7b, and one end of the printed board 7a as shown in (a) plan view and (b) side view of the burn-in board outline view in FIG. And a connector 7c provided on the printed circuit board 7a.
The C connectors 7d are arranged and configured to mount an IC package.

As shown in FIGS. 10 and 11, a burn-in board 7 having an IC package mounted on an IC connector 7d is mounted on the board rack 4 inserted into the thermostat as described above.
Is inserted on the rails 4a, 4a, and the connector 7c is inserted into the internal connector 5b of the feed-through board 5 mounted on the rear door 3 of the thermostatic bath as shown in FIGS.
Connected to an external power supply and signal source 6. The feed-through board 5 is provided with an internal connector 5b on the inside and an edge connector 5a on the outside as shown in FIG. 13 (a) plan view and (b) side view of the feed-through board outline view. It is connected to the.

After the insertion of the burn-in board 7 in this way, the inside is closed by the door 2, and after the temperature is raised to a predetermined temperature, a test is performed by applying required voltages and signals from the power supply and the signal source 6.

After the test, the door 2 is opened after cooling to room temperature, the burn-in boards 7 are removed one by one, and the process is terminated.

[0009]

However, the internal connector 5b of the feed-through board 5 and the connector 7c of the burn-in board 7 have a large number of pins and require a large force for insertion and removal as a whole.
, The insertion and withdrawal take a considerable amount of time.

[0010] For this reason, the present applicant has filed Japanese Utility Model Application No. 60-576.
No.5 proposed a board pulling device using an air cylinder, but the present invention was only a pulling process and did not completely solve the above problems.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a burn-in board insertion / removal device of a burn-in device which can easily insert and withdraw the above-mentioned problem.

[0012]

In order to solve the above-mentioned problems, in the burn-in device, the back door of the main body 1 is formed by a box-shaped holding frame 11 having an open surface on the main body 1 side. Inside a holding frame 11 which is a rear door, a box-shaped movable frame 12 having an open surface on the side of the main body 1 is provided.
A rear wall 14 fixed to an open surface of the movable frame 12, and a plurality of feeds provided so as to penetrate between a surface of the rear wall 14 on the main body 1 side and an inner surface of the movable frame 12. the holding frame tripartite the through board 5 so as allowed to slide structure which is integrated in the horizontal direction 11
Inside of both sides of the movable frame 12 and outside of both sides of the movable frame 12
And a sliding device 13 is provided between
The board rack 4 inserted and fixed in the main body 1
The burn-in board
The device is provided with a burn-in board insertion / extraction device composed of the structure held in the holding frame 11 and the sliding device 13 for inserting / extracting the card 5.

[0013]

1 and 2 are sectional views of a thermostat equipped with a device for inserting and removing a burn-in board according to the present invention, FIG. 1 is a longitudinal sectional view in the front-rear direction, and FIG. is there. Portions other than the insertion / extraction device are the same as those except for the rear door 3 in FIG. 3, and therefore only the insertion / extraction device and portions related thereto will be described.

A box-shaped holding frame 11 made of a heat insulating material is provided on the entire back surface of the main body 1 of the thermostat.
Box-shaped movable frames 12, 12 are respectively provided in upper and lower halves of the inside. This movable frame 12
Is configured to slide in the front-rear direction by an air cylinder or the like (not shown) by four sliding devices 13, 13, 13, 13 provided on the inner surface of the holding frame 11, respectively.

[0015] This is the movable frame 12 and the rear wall 14 is fixed in a thermostatic chamber inner side, the movable frame 12 are a plurality of feedthrough board 5 in the horizontal direction at regular intervals to the rear wall 14 is inserted and fixed, rear Wall 14 and feeds
A rotatable board 5 is formed integrally with the three members, and an end of the feedthrough board 5 in the movable frame 12 is formed.
The edge connector 5a or the cable connector 8
a is connected to the power supply and the signal source 6, respectively.

In the above embodiment, the movable frame 1
Although the 2 and the rear wall 14 are vertically divided into two, it is not always necessary to divide into two, and it is needless to say that they are not divided or may be divided into three or more.

Next, the operation of the above insertion / removal device will be described. FIG. 3A is an explanatory view of a burn-in board replacing operation using the insertion and removal device of the present invention, and FIG. 3B is an explanatory view of a conventional burn-in board replacing operation.

In the conventional case, as shown in (b), the burn-in boards 7 are inserted or withdrawn one by one.
a, 4a and fixed to the board rack 4 by a lock mechanism (not shown). In such a state, the board rack 4 is inserted and fixed in a thermostat, and the movable frame 12 and the rear wall 14 are fixed to the board rack 4 by air while the burn-in board 7 of the upper half or the lower half is fixed to the board rack 4 as shown in FIG. The cylinder is moved forward or backward by operation of a cylinder or the like, and insertion or extraction is performed simultaneously.

[0019]

As described above, when the burn-in board 7 is mounted on the board rack 4, the burn-in board 7 is mounted outside the thermostatic chamber, and at this time, there is no insertion into the connector. Complete with

After the board rack 4 on which the burn-in board 7 is mounted is inserted and fixed in a constant temperature bath, it can be simultaneously inserted into or removed from the connector by an air cylinder or the like.
The work is easy and the insertion and removal can be automated.
