Description

Technical Field

[0001] This utility model relates to the field of semiconductor testing technology, specifically a single-sided locking hand tester. Background Technology

[0002] Semiconductor test chips are widely used miniature connectors in fields such as medical, microelectronics, and optoelectronics. The main performance characteristics of semiconductor test probes include impedance and elasticity. Because products used in applications with high precision and especially high performance requirements, mechanical and electrical properties need to be tested during finished product inspection. A common testing method involves placing the semiconductor test probes on specialized equipment. However, during testing, the probes often come into contact with the device under test (DUT). If the applied force is not properly controlled, overvoltage can damage the semiconductor test probes.

[0003] Therefore, in view of the above situation, there is an urgent need to provide a single-sided lock attachment hand detector to overcome the shortcomings in current practical applications. Utility Model Content

[0038] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0039] Please see Figures 1-7 This utility model provides a single-sided locking hand probe, which includes a base 101 and a second boss 207. The base 101 has a first boss 201 on its side, and a working platform 206 is provided on the first boss 201. A bearing seat 112 is provided on the working platform 206, and the base 101 and the bearing seat 112 are rotatably connected by a first pin 205. The feature is that it further includes:

[0040] The cam push rod 102 is rotatably connected to the base 101 via a stop pin 106, and the end of the stop pin 106 is provided with a retaining ring 107.

[0041] The bottom cover 103 and the pressure cover 104 are located below the cam push rod 102. The pressure cover 104 is fixed to the bottom cover 103, and a positioning pin 108 is provided between the pressure cover 104 and the bottom cover 103. There are multiple positioning pins 108.

[0042] Conductive copper block 111 is located in the middle of bottom cover 103 and pressure cover 104. There are two spring placement holes at the upper end of conductive copper block 111. Spring 2 110 is installed in the spring placement holes. The end of spring 2 110 abuts against bottom cover 103. Conductive post 116 is provided at the lower end of conductive copper block 111. Conductive copper block 2 117 is fixed on conductive post 116.

[0043] A test probe base 114 is located below the pressure cap 104, and a test probe 113 is provided on the test probe base 114;

[0044] The latch 105 is connected to the end of the base 101 by a pin 208, and a spring 4 203 and a spring 5 204 are respectively provided on the pin 208. The upper part of the spring 4 203 abuts against the latch 105, and the spring 5 204 abuts against the base 101.

[0045] It also includes pin 205, and the working platform 206 is also provided with a positioning structure for use with pin 205.

[0046] In this embodiment of the invention, the hand probe base 101 is the main supporting component of the overall structure, and all other components are connected to this component. The cam push rod 102 is fixed to the base 101 by a stop pin 106 and a retaining spring 107. The cam push rod 102 is I-shaped, and the worker can press down the cam push rod 102 with only two fingers during operation. The bottom cover 103 below the cam push rod 102 is limited by a horizontal plate inside the base 101, and the pressure cover 104 below the bottom cover 103 is... The bolts are fixed to the bottom cover 103. A positioning pin 108 is provided between the pressure cover 104 and the bottom cover 103, its main function being to ensure more accurate positioning of the chip when the protrusion of the pressure cover 104 is pressed against it. Between the bottom cover 103 and the pressure cover 104 is a conductive copper block 111, which is embedded in the pressure cover 104. The upper end of the conductive copper block 111 has two spring placement holes, on which a second spring 110 is installed. The other end of the second spring 110 abuts against the bottom cover 103. The lower end of the conductive copper block 111... Conductive copper block 117 is fixed by conductive post 116 and is embedded in pressure cap 104. The elasticity of spring 110 prevents overvoltage from the conductive copper block 117 on the chip, thus preventing damage to the test probes. Springs 109 and 115 are mounted on base 101, abutting against bottom cover 103 and pressure cap 104, allowing the chip to return to its original position after testing, while also preventing pressure cap 104 from damaging the chip during operation. To prevent overpressure, a latch 105 is connected to the side of the base 101 via a pin 208. The latch also contains a spring 203. The upper part of the spring 203 abuts against the latch 105, and the lower part of the spring 204 abuts against the base 101, thus achieving a spring-back effect after pressing. This structure is for securing the latch to the testing platform below during testing. A pin 208 is also located on the opposite side of the latch 105 and embedded in the base 101, for connection to the lower working platform. The latch fixing surface 202 is a horizontal plane. When the entire hand-held device is placed on the working platform, the latch 105 is compressed by the spring 203 and becomes vertical, locking the latch fixing surface 202 onto the working platform, thus ensuring the stability of the entire hand-held device.

[0047] In summary, the working principle of this utility model is as follows: When using the single-sided locking hand probe, first fix the pin 205 to the lower working platform 206, then place the chip into the working platform 206, as follows... Figure 1 The latch 105 in the middle is also locked to the work platform 206. There is a protrusion 201 on the side of the base 101, which restricts the movement angle of the latch 105, so that the hand probe structure and the work platform part achieve an overall fixed effect.

[0048] The cam push rod 102 is moved to start working. Because the cam push rod 102 and the stop pin 106 are fixed eccentrically, the cam push rod 102 exerts a downward squeezing force on the bottom cover 103 during movement, thus achieving the downward movement of the bottom cover 103, the pressure cover 104, the first conductive copper block 111, and the second conductive copper block 117. The pressure cover 104 has a second boss 207 on its lower side, which is used to press the test position of the chip pins. A third spring 115 is installed at the fixing point of the pressure cover 104. This spring 115 gives the pressure cover 104 a certain elastic potential energy, ensuring that overpressure does not occur during the downward pressing process. The second conductive copper block 117 is in constant contact with the chip. The upper end of the first conductive copper block 111 has a second spring 110, which is used to prevent overpressure on the chip and maintain the stability of detecting air bubbles in the chip's encapsulation. After the test, the cam push rod 102 is pushed back to its original position. Due to the upward push of spring 109 and spring 315, the bottom cover 103 and the pressure cover 104 have a tendency to move in opposite directions. The positioning pin 108 is connected to the bottom cover 103. During the upward movement of the bottom cover 103, it will be stopped by the limiting relationship between the positioning pin 108 and the base 101.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
