Description

Pusher apparatus for electrical test

The present invention relates to a pusher device for an electrical test, and more particularly, to a pusher device for an electrical test that enables uniform pressure to be applied to the entire device without the need for a large force in a narrow space.

In general, a semiconductor inspection apparatus sequentially conveys and pressurizes a device to be inspected, such as a semiconductor package, to a position of the inspection apparatus, and conducts an electrical inspection on each of the devices under test according to a predetermined test program. At this time, after returning to a predetermined location according to the inspection result, defective products and good products are classified into each other according to whether or not the product is acceptable or not. In a series of operations of the semiconductor inspection apparatus, the pusher device presses the device to be inspected, which has been moved toward the inspection apparatus, toward the inspection apparatus. In order to ensure that the terminal of the device to be tested and the pad of the testing device are in contact with each other, the device to be tested is pressed with an appropriate pressure to come into contact with the pad of the testing device.

The conventional pusher device 10 is configured to include a base body 20 , a handle 30 , and a pusher body 40 as shown in FIGS. 1 to 5 . The base body 20 is fixedly installed on the side of the inspection apparatus and has the shape of a square plate, and an accommodation space 21 in which the device to be inspected 50 is accommodated is provided in the center thereof. The accommodating space 21 has a rectangular cross-sectional shape corresponding to the device to be inspected 50 .

Four first bolts 22 are formed around the accommodating space 21 in the base body 20, and the first bolts 22 allow the handle 30 to be detachably coupled.

The handle 30 has a circular plate shape as a whole, and an insertion space 31 extending from the center to the upper side is provided.

A plurality of cutouts 32 penetrating up and down are provided at the edge of the handle 30, and the cutouts 32 include an insertion portion 32a into which the first bolt 22 is inserted, and the first bolt 22 ) is provided with a locking jaw (32b) to catch. When the handle 30 is rotated after the first bolt 22 is inserted through the insertion part 32a, the head of the first bolt 22 is caught by the locking jaw 32b, so that the handle 30 is connected to the base body 20 ) is prevented from escaping.

The pusher body 40 is to contact the upper surface of the device to be tested 50 disposed in the receiving space 21 of the base body 20 to press the device to be tested 50 toward the testing apparatus. This pusher body 40 is inserted into the insertion space 31 of the base body 20, and the handle 30 by a plurality of second bolts 33 penetrating the central portion of the pusher body 40. ) is bound to

A second spring 34 is inserted into the second bolt 33 to elastically bias the pusher body 40 in a direction away from the base body 20 .

The conventional pusher device 10 having such a structure operates as follows.

First, after inserting the device to be inspected 50 into the receiving space 21 of the base body 20 , the handle 30 is positioned above the base body 20 . After aligning the insertion portion 32a of the handle 30 with the first bolt 22 , the first bolt 22 is inserted through the insertion portion 32a of the handle 30 . When the operator presses the handle 30 toward the base body 20 , the pusher body 40 elastically supported by the second spring 34 presses the device under test 50 with a predetermined force. When the operator rotates the handle 30 in one direction while pressing the handle 30 , the first bolt 22 moves from the insertion part 32a to the locking jaw 32b so that the handle 30 is coupled to the base body 20 . will keep At this time, since the second spring 34 gives tension to the pusher body 40 , the pusher body 40 reliably contacts the device to be inspected 50 with the inspection apparatus while having a predetermined pressing force.

Thereafter, when a predetermined electrical signal is applied from the inspection apparatus, the signal flows through the pad of the inspection apparatus to the terminal of the inspection apparatus, and a predetermined electrical inspection is performed.

After the electrical inspection is completed, if the handle 30 is rotated in the opposite direction while applying a predetermined pressing force, the first bolt 22 is moved from the locking protrusion 32b to the insertion part 32a, and then the handle As the 30 is separated from the first bolt 22 , the receiving space 21 of the base body 20 can be opened, and the device to be inspected 50 is transported to a predetermined position.

Such a conventional pusher device 10 has the following problems.

First, in the conventional pusher device 10, after inserting the handle 30 into the first bolt 22, a force is applied to rotate the handle 30 only with the force of the hand while the second spring 34 is compressed. Because it is necessary to press the device to be inspected 50, it causes great inconvenience to the operator.

That is, since the operator has to rotate the handle 30 while pressing the handle 30 by hand in order to apply pressure to the pusher body 40, it causes inconvenience to the operator.

Second, in the pusher device 10, the handle 30 and the pusher body 40 are fixedly coupled by the second bolt 33, and the handle 30 and the pusher body 40 are configured to rotate integrally. do. That is, when the handle 30 is rotated, the pusher body 40 is also configured to rotate at the same time. In the pusher device 10 having such a structure, when the handle 30 is rotated while in contact with the device to be inspected 50, the pusher body 40 is also rotated at the same time, and the pusher body ( 40) While the pusher body 40 in the form of a rectangular parallelepiped collides with the inner wall of the receiving space 21 in the process of rotation, there is a fear that the edge of the pusher body 40 is damaged.

In particular, since the pusher body 40 must rotate within the receiving space 21, the size of the pusher body 40 must be sufficiently smaller than the cross section of the receiving space 21, the size of the pusher body 40 If is not large, the front surface of the device under test 50 cannot be sufficiently pressed, so that the terminal of the edge of the device under test 50 cannot be pressed with the pad of the test device with sufficient pressure.

It is also possible to configure the pusher body 40 to have a circular cross-section in order to prevent the corner from collided with the inner wall of the receiving space 21 in the process of rotating the pusher body 40, but in this case, the It may not be possible to press the edge of the rectangular shape), so that the pressure is not evenly distributed in the body of the device to be tested 50, which may be a factor of lowering the reliability of the test.

Thereafter, the device to be inspected 170 is removed from the accommodation space 111a.

In the pusher device 100 for the electrical inspection according to the present invention, unlike the conventional one, the operator can apply or remove the pressing force by the rotational operation, so that a simple pushing operation can be performed, and the operator needs to apply a large force The work becomes convenient without

In addition, the pusher member 140 can apply a pressing force to the device to be inspected 170 without rotation in the receiving space 111a despite the rotation of the handle part 120, so that the pusher member 140 is moved to the receiving space ( 111a) It is possible to prevent damage to the edge of the pusher member 140 without colliding with the inner wall.

In addition, the pusher member 140 can maintain a state spaced apart from the second bolt 160 during the pressing process, so that the pusher member 140 enables free relative rotation with respect to the interposer 130, and thus the pusher member ( 140) can be reliably prevented from colliding with the inner wall of the receiving space (111a).

In addition, there are cases in which the manual housing is tested sideways because the board is erected vertically in the actual inspection environment, and there is another device next to the board to test from the side, so it is necessary to develop a housing that can fit in between. can be easily inspected even in a narrow space, thereby reducing the number of parts and lowering the height of the base member 110 and the handle.

In addition, the present invention enables stable inspection by allowing the support 112 to function as a stopper so that the device to be inspected 170 or the inspection apparatus 180 is not damaged as the handle is rotated excessively.

Although the present invention has been described in detail with reference to preferred embodiments above, the present invention is not necessarily limited to these embodiments, and various modifications may be made within the scope without departing from the technical spirit of the present invention.
