Abstract
Description
[Technical Field]
[0001] The present invention relates to a press tool for a chip testing apparatus, and more particularly to a press tool including a locating bead (also known as a ball plunger). [Background technology]
[0002] As the performance requirements of electronic products increase, various types of chips are widely developed, and chip quality checks are particularly emphasized. Currently, most chip testing devices include a pressing tool for pressing the chip under test and a chip test socket for accommodating the chip under test, where the pressing tool is, for example, a conventional manual lid (hand test cover, hand socket lid, or manual actuator), and the chip test socket is, for example, a conventional integrated circuit testing socket (IC Socket).
[0003] The chip testing device mainly performs various testing items by manually or automatically rotating the pressing tool to apply pressure to the chip under test in the chip test socket, thereby ensuring that all contact points on the chip under test are in full electrical contact with the testing element in the chip test socket.
[0004] 1, the chip testing device includes a pressing tool 8 for pressing a chip to be tested 90 and a chip test socket 9 for receiving the chip to be tested 90. The pressing tool 8 includes a base 81, a driving member 82, a buffer unit 83, and a pressing member 84 for pressing the chip to be tested 90. The driving member 82 rotates relative to the base 1 and moves toward the pressing member 84, thereby driving the pressing member 84 to press the chip to be tested 90. The buffer unit 83 is used to absorb excess pressure from the driving member 82 to prevent the chip to be tested 90 from being damaged by excessive pressure. The buffer unit 83 includes a separator 831 located between the pressing member 84 and the driving member 82 and a plurality of elastic members 832.
[0005] However, since the driving member 82 and the separator 831 of the buffer unit 83 are in contact with each other by bonding surfaces, when the driving member 82 rotates, the friction force between the contact surface of the driving member 82 and the contact surface of the separator 831 is relatively large, and dust is easily generated due to friction, which may contaminate the test chip 90 with dust or affect the test. Summary of the Invention [Problem to be solved by the invention]
[0006] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a press tool. [Means for solving the problem]
[0007] The pressing tool of the present invention is used in combination with an inspection jig to press a sample to be inspected against the inspection jig.
[0008] The pressing device includes a base, a pressing member, and a drive control unit. The pressing member is mounted on the base and movable relative to the base, and is used to press the test sample against the testing fixture. The drive control unit rotates relative to the base and moves toward the pressing member, and includes a drive member and a plurality of elastic buffer members. The drive member is mounted on the base and faces the pressing member. The elastic buffer members are attached within the drive member and moved by the drive member to drive and move the pressing member to press the test sample, and each elastic buffer member includes a positioning bead exposed outside the drive member, ensuring a gap between the drive member and the pressing member. [Effects of the Invention]
[0009] The advantage of the present invention is that by setting the elastic buffer member, if the force provided by the driving member of the pressing tool is excessive, the excess force is absorbed by the elastic buffer member, and the friction force between the positioning bead and the pressing member is relatively small, which reduces the generation of dust, thereby preventing the problem of the chip to be tested being contaminated with dust or the test being affected by dust.

DETAILED DESCRIPTION OF THE INVENTION
[0011] Before describing the present invention in detail, it should be noted that in the following description, like elements are designated by like reference numerals.
[0012] Referring to FIG. 2 , an embodiment of a pressing tool of the present invention is combined with an inspection jig 10 to press a test sample 20 onto the inspection jig 10. The inspection jig 10 is, for example, a chip test socket. The chip test socket is, for example, an integrated circuit testing socket. The test sample 20 is, for example, an integrated circuit chip. The integrated circuit chip may be, for example, an automotive chip, an AI inference chip, a wearable device chip, a 5G chip, or a data center chip. In this embodiment, the inspection jig 10 includes a mounting table 101 on which the test sample 20 is mounted, and the mounting table 101 includes two engaging portions 102.
[0013] Referring to FIGS. 2, 3 and 5, the pressing tool includes a base 1, a pressing member 2, a drive control unit 3, two engaging members 4, two pivots 5, and a rotating shaft member 6.
[0014] The base 1 includes a stopper 11. The stopper 11 is used to limit the angular displacement of the rotation and the linear displacement of the movement of the drive control unit 3.
[0015] The pressing member 2 is provided on the base 1 and is movable relative to the base 1, and is used to press the sample 20 to be inspected onto the inspection jig 10.
[0016] The drive control unit 3 can rotate relative to the base 1 and move toward the pressing member 2. The drive control unit 3 includes a drive member 31, a plurality of elastic buffer members 32, a grip 33, and a plurality of fixing members 34.
[0017] The driving member 31 is disposed on the base 1 and is opposed to the pressing member 2. The driving member 31 includes a plurality of mounting holes 310. In this embodiment, the number of the mounting holes 310 is nine. It should be noted that the number of the mounting holes 310 can be adjusted according to the cushioning requirements and the size of the driving member 31, and is not limited to nine, and may be two, three, four, five, ten, etc.
[0018] The elastic buffer members 32 are respectively mounted in the mounting holes 310 of the driving member 31 and are moved by the driving member 31 to move the pressing member 2 and cause the pressing member 2 to press the test sample 20. In this embodiment, there are nine elastic buffer members 32. It should be noted that the number of the elastic buffer members 32 and the number of the mounting holes 310 may be the same or different. The number of the elastic buffer members 32 can be adjusted according to the buffering requirements and the number of the mounting holes 310, and is not limited to nine, and may be two, three, four, five, seven, etc. Each elastic buffer member 32 includes a positioning bead 321 and an elastic member 322 located in each mounting hole 310. A portion of each positioning bead 321 is exposed to the outside of each mounting hole 310 of the driving member 31, and is positioned between the pressing member 2 and each elastic member 322, thereby providing a gap between the driving member 31 and the pressing member 2. In this embodiment, the elastic member 322 is a spring.
[0019] The grip 33 is mounted on the driving member 31 and spaced apart from the base 1. A groove 330 is formed in the surface of the grip 33 facing the driving member 31, and the groove 330 has two opposite closed ends. A stopper 11 of the base 1 extends into the groove 330, and when the drive control unit 3 rotates and moves toward the pressing member 2, one of the closed ends engages with the stopper 11 to stop the rotation and movement of the drive control unit 3, thereby limiting the angular displacement of rotation and the linear displacement of the drive control unit 3. The depth of the groove 330 is equal to or greater than the length of the stopper 11.
[0020] These fixing members 34 integrally fix the grip 33 and the driving member 31. In this embodiment, each fixing member 34 is a screw.
[0021] These hooking members 4 are attached to the base 1 and can swing relative to the base 1, and each hooking member 4 can be detachably attached to each engaging portion 102 of the mounting table 101.
[0022] The pivots 5 pass through the hook members 4 respectively, and each pivot 5 has two ends inserted into the base 1 in opposite directions.
[0023] The rotary shaft member 6 passes through the base 1 , the pressing member 2 , the driving member 31 and the grip 33 .
[0024] 4 to 7, the operation of the press tool is as follows: The grip 33 is rotated to rotate the driving member 31, and a force is applied to move the driving member 31 toward the pressing member 2, pressing the positioning beads 321 of the elastic buffer member 32 against the pressing member 2. The positioning beads 321 continuously press the pressing member 2, causing the pressing member 2 to move toward the test sample 20 and press the test sample 20. If the driving member 31 applies excessive force during the rotation and movement of the driving member 31, the excess force is absorbed by the elastic buffer member 32, preventing the pressing member 2 from excessively pressing the test sample 20 and damaging the test sample 20. The groove 330 of the grip 33 engages with the stopper 11 of the base 1, thereby controlling the angular displacement of the rotation and the linear displacement of the drive control unit 3. At the same time, when the elastic buffer member 32 rotates, the contact area between the positioning beads 321 and the pressing member 2 is small, so the friction force between the positioning beads 321 and the pressing member 2 is small, making it difficult for dust to be generated between the positioning beads 321 and the pressing member 2.
[0025] As described above, by setting the elastic buffer member 32, if the force provided by the driving member 31 of the pressing tool becomes excessive, the excess force is absorbed by the elastic buffer member 32, and since the friction force between the positioning bead 321 and the pressing member 2 is relatively small, the generation of dust can be reduced, and problems such as dust contaminating the chip to be tested or dust affecting the test do not occur, thereby reliably achieving the object of the present invention.
[0026] However, the above is merely an example of the present invention and should not be construed as limiting the scope of the present invention. Simple and equivalent changes and modifications made based on the claims and the contents of the patent specification of the present invention are still within the scope of the patent coverage of the present invention.
