Abstract
Description
Technical Field
[0001] This application relates to the field of chip testing, and in particular to a pressure-adaptive testing module. Background Technology
[0002] After the chips are manufactured, they still need to undergo performance testing. Workers classify the chips according to the test results: good chips (those with good test results) and defective chips (those with abnormalities). Defective chips are collected and sent to a laboratory to analyze the causes of the problems, which helps to improve production processes or equipment.
[0003] Existing chip testing modules typically use a cylinder to drive a test head to press down and test product performance. However, due to the wide variety of chips available, directly driving the test head with a cylinder cannot meet the testing pressure requirements of different products. Utility Model Content
[0004] To improve the practicality of the test module and reduce the possibility of chip scratches during testing, this application provides a pressure-adaptive test module.
[0005] This application provides a pressure adaptive testing module, which adopts the following technical solution:
[0006] A pressure adaptive test module includes a test module body and an adjustment component disposed on a test head of the test module body. The adjustment component includes a mounting base disposed on the test module body for positioning the test head, an elastic element disposed on the mounting base and whose bottom end is connected to the test head of the test module body, a positioning element disposed on the upper end of the elastic element, and a pushing element disposed above the positioning element. The pushing element is used to drive the positioning element to move up and down.
[0007] By adopting the above technical solution, the pusher is used to push the positioning member to press down on the elastic member. The pressing down of the elastic member drives the test head to press down on the test chip. The elastic member provides a squeezing and clamping force for the test module, reducing the possibility of damage to the chip caused by the direct hard impact of the test head on the chip. At the same time, it increases the clamping force of the test head on the chip. The adjustment component of this application effectively improves the test effect of the test module, enhances the practicality of the test module, and facilitates the control of the degree of squeezing of the positioning member by the pusher according to the different test pressures required for different products. It also facilitates the staff to control the test pressure independently.
[0008] Preferably, the pushing component includes a motor mounted on a mounting base, a lead screw mounted on the output end of the motor, and a pushing block threadedly connected to the lead screw. The mounting base has a moving groove along the length of the lead screw for moving the pushing block.
[0009] By adopting the above technical solution, the motor drives the lead screw to rotate, and the rotation of the lead screw causes the push block to move along the length of the lead screw. The moving groove improves the stability of the push block's movement.
[0010] Preferably, the bottom surface of the push block is sloping, and the positioning member includes a telescopic block disposed below the push block and above the elastic member, the top surface of the telescopic block being sloping and conforming to the sloping surface of the push block.
[0011] By adopting the above technical solution, the bottom surface of the push block is sloping. When the push block moves horizontally, it drives the telescopic block to move up and down. The top surface of the telescopic block is sloping, and the slope of the telescopic block is in contact with the slope of the push block. When the push block moves, the slope of the push block squeezes the slope of the telescopic block to move up or down, thereby driving the elastic element below to squeeze the test head and provide test pressure for the test head.
[0012] Preferably, the top surface of the telescopic block has a groove.
[0013] By adopting the above technical solution, a groove is provided on the top surface of the telescopic block, which facilitates the push block to push the telescopic block to move up and down.
[0014] Preferably, the mounting base has a positioning groove along the height direction for the expansion and contraction of the elastic element.
[0015] By adopting the above technical solution, the positioning groove improves the stability of the elastic element during expansion and contraction.
[0016] In summary, this application adjusts the test pressure of the test head on the product by adjusting the component. The staff can independently control the test pressure of the test module and adjust the corresponding test pressure for different products without having to repeatedly replace the test module, thus reducing testing costs.

[0022] The following is in conjunction with the appendix Figures 1-4 The present invention will be further described below. The following embodiments are only used to more clearly illustrate the technical solution of this application, and should not be used to limit the protection scope of the present invention.
[0023] In the description of this application, it should be noted that the orientations or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0024] This application discloses a pressure adaptive testing module. (Refer to...) Figure 1 , Figure 2 and Figure 3 The test module includes a test module body 1 and an adjustment component 3 mounted on a test head 2 on the test module body 1. The adjustment component 3 is used to adjust the test pressure of the test head 2 on the chip. The adjustment component 3 includes a mounting base 31 mounted on the test module body 1, a pusher 34 mounted on the mounting base 31, a positioning member 33 located below the pushing end of the pusher 34, and an elastic member 32 located below the positioning member 33. One end of the elastic member 32 is connected to the positioning member 33, and the other end of the elastic member 32 is connected to the test head 2 on the test module body 1. The pusher 34 is used to push the positioning member 33 down to press down the elastic member 32, thereby controlling the test pressure of the test module.
[0025] Reference Figure 2 and Figure 3The pushing component 34 includes a motor 341 mounted on a mounting base 31, a lead screw 342 fixedly mounted on the output end of the motor 341, and a pushing block 343 threadedly connected to the lead screw 342. The motor 341 drives the lead screw 342 to rotate, and the rotation of the lead screw 342 causes the pushing block 343 to reciprocate along the length of the lead screw 342. To improve the stability of the lead screw 342 during movement, the mounting base 31 has a moving groove 4 along the length of the lead screw 342 for the reciprocating movement of the pushing block 343, thereby improving the stability of the pushing block 343 during movement. In this embodiment, multiple sets of motor 341, lead screw 342, pushing block 343, positioning component 33, and elastic component 32 are set to correspond to the number of test heads 2, improving the control effect of the adjustment component 3 on the test heads 2. In specific implementation, the operator can set them according to the equipment area and the number of test products.
[0026] Reference Figure 1 and Figure 3 When the push block 343 reciprocates, it drives the positioning member 33 to move up and down. In this embodiment, the bottom surface of the push block 343 is sloped, and the positioning member 33 includes a telescopic block 331 located below the push block 343. The top surface of the telescopic block 331 is sloped and is in close contact with the push block 343. In this embodiment, the telescopic block 331 moves up and down, and the push block 343 moves horizontally. When the push block 343 moves horizontally, the slope drives the telescopic block 331 to move up and down. This directional setting is mainly used to reduce the installation space of the adjustment component 3, improve space utilization, and reduce interference between equipment components. In specific implementation, the lead screw 342 can also drive the push block 343 to move up and down, directly driving the telescopic block 331 to move up and down. In order to facilitate the movement of the push block 343 and the telescopic block 331, a groove 5 is provided on the top surface of the telescopic block 331. The groove 5 is used to reduce the phenomenon of tight contact between the surfaces of the push block 343 and the telescopic block 331, and to reduce the possibility that the tight contact between the push block 343 and the telescopic block 331 will hinder the drive of the lead screw 342.
[0027] Reference Figure 3 and Figure 4 When the push block 343 drives the telescopic block 331 to move up and down, the telescopic block 331 synchronously squeezes the elastic element 32, making it easier for the staff to independently control the test pressure of the test module. In order to improve the stability of the telescopic movement of the elastic element 32, the mounting base 31 is provided with a positioning groove 6 for the telescopic movement of the elastic element 32 along the height direction. In this embodiment, the elastic element 32 is a spring.
[0028] The implementation principle of the pressure adaptive testing module in this application embodiment is as follows: When the product needs to be replaced and the test pressure needs to be adjusted, the operator starts the motor 341 to drive the lead screw 342 to rotate. The rotation of the lead screw 342 drives the push block 343 to move. The movement of the push block 343 drives the telescopic block 331 to move and press the elastic element 32. The elastic element 32 provides test pressure to the test head 2. The operator can control the downward pressing distance of the telescopic block 331 according to the product needs, thereby controlling the test pressure of the elastic element 32 on the test head 2, and thus adjusting the test pressure of the test head 2 on the product. This application effectively improves the practicality of the testing module, eliminates the need for frequent replacement of the test head, and reduces testing costs.
[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
