[0002] Semiconductor devices are electronic devices with electrical conductivity between that of good conductors and insulators, utilizing the unique electrical properties of semiconductor materials to perform specific functions. They can be used to generate, control, receive, transform, amplify signals, and perform energy conversion. Made of silicon, germanium, or gallium arsenide, semiconductor devices can be used as rectifiers, oscillators, light emitters, amplifiers, photometers, and other devices. Sometimes referred to as discrete devices to distinguish them from integrated circuits, the basic structure of most two-terminal devices (i.e., crystal diodes) is a PN junction. Semiconductor devices typically utilize different semiconductor materials, processes, and geometries. A wide variety of crystal diodes with diverse functional applications have been developed, covering a frequency range from low and high frequencies, microwaves, millimeter waves, infrared, and even optical waves.

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0037] The present invention provides a semiconductor device screening test device, referring to Figures 1-11 , the present invention provides three embodiments: Example

[0039] The testing mechanism 3 includes a semiconductor body 301 disposed within the test chamber 2. A wire body 302 is connected to the surface of the semiconductor body 301. Bolts are provided to securely connect the wire body 302 to the surface of a movable plate 303, which allows the movable plate 303 to move the wire body 302. The connection between the wire body 302 and the packaged device of the semiconductor body 301 is tested, and the airtightness of the connection is tested by the provision of pure water.

[0040] A movable plate 303 is fixedly connected to the surface of the wire body 302 via bolts. A linkage tooth plate 304 is fixedly connected to the surface of the movable plate 303. A driving gear 305 is meshed with the surface of the linkage tooth plate 304. A guide cylinder 306 fixedly connected to the interior of the test box 2 is attached to one side of the semiconductor body 301. A striking rod 307 is slidably inserted into the interior of the guide cylinder 306. A movable plate 308 is fixedly connected to the surface of the striking rod 307.

[0041] During the movement of the striking rod 307, the movable plate 308 is synchronously driven to move, so that the movable plate 308 drives the driving tooth plate 309 to move, so that the driving tooth plate 309 is self-engaged with the driving gear 305, thereby causing the driving gear 305 to mesh and rotate, driving the linkage tooth plate 304 and the driving tooth plate 309 to move in opposite directions, thereby driving the movable plate 303 to move;

[0042] The testing mechanism 3 also includes a support rod 310 fixedly connected to one side of the support plate 413. The setting of the support rod 310 makes it more stable when the magnet block 311 drives the semiconductor body 301 to rotate. The surface of the support rod 310 is rotatably sleeved with the magnet block 311. The surface of the magnet block 311 is fixedly connected to a connecting frame 312 fixedly connected to the sealing cover 416. The sealing box 403, the sealing cover 416 and the magnet block 311 are fixedly connected by the connecting frame 312. The surface of the connecting frame 312 is fixedly connected to a guide plate 313 slidably connected to the linkage gear plate 304. The setting of the guide plate 313 can not only limit the linkage gear plate 304, but also guide the linkage gear plate 304, thereby making the linkage gear plate 304 more stable when moving;

[0043] The driving gear 305 is rotatably connected to the connecting frame 312 via a bearing seat. A driving mechanism 5 is installed on one side of the striking rod 307.

The surface of the rotating disk 503 is rotatably connected to a flip plate 504 rotatably connected to the striking rod 307 via a pin. The surfaces of the rotating rod 502 and the guide cylinder 306 are both sleeved with a limiting tube fixedly connected to the test box 2. The provision of the limiting tube makes the rotating rod 502 and the guide cylinder 306 more stable during use.

[0044] Start the driving motor 501 so that its output end drives the rotating rod 502 to rotate, thereby causing the rotating disk 503 to drive the flip plate 504 to move through the pin shaft, causing the striking rod 307 to move back and forth inside the guide cylinder 306, so that the striking rod 307 strikes one side of the semiconductor body 301 to test the strength of the semiconductor body 301 packaged device. At the same time, through the setting of pure water, observe whether the pure water produces bubbles to test the airtightness of the semiconductor body 301 packaged device.

[0045] Embodiment 2, based on embodiment 1, further, a pin detection mechanism 4 is installed inside the test mechanism 3, and the pin detection mechanism 4 includes pins 401 fixedly connected to one side of the semiconductor body 301 in a rectangular array, and the surfaces of several pins 401 are commonly sleeved with a fixing plate 402, and the surface of the fixing plate 402 is slidably sleeved with a sealing box 403 corresponding to the semiconductor body 301, and the surface of the sealing box 403 is fixedly connected with a sealing cover 416 by bolts, and the upper surface of the sealing cover 416 is fixedly connected with a reset spring 6. Through the setting of the reset spring 6, after the tensile performance test of the pin 401 by the moving rod 405 and the fixing plate 402, the moving rod 405 is moved. The rod 405 can be automatically reset, which is convenient for repeated use of the pin detection mechanism 4. One end of the reset spring 6 is fixedly connected to the hook 7. The surface of the hook 7 is fitted with a limit ring fixedly connected to the adsorption plate 415. Through the mutual cooperation of the hook 7 and the limit ring, when the fixed plate 402 is replaced, the hook 7 and the push plate 411 are detachable, avoiding the reset spring 6 from hindering the movement of the push plate 411. One side of the fixed plate 402 is provided with a plug-in slot 404 corresponding to the pin 401. One side of the fixed plate 402 is fixedly connected to the moving rod 405 by a bolt. The fixed plate 402 and the moving rod 405 are both slidably connected to the interior of the sealing box 403.

[0046] The pin detection mechanism 4 also includes a connecting pipe 406 fixedly connected to the surface of the fixed plate 402 and connected to the plug-in slot 404, one end of the connecting pipe 406 is fixedly connected to a water collecting box 407 with glue inside, the water collecting box 407 is fixedly connected to the moving rod 405, the interior of the water collecting box 407 is slidably connected to an extrusion plate 408, the surface of the extrusion plate 408 is threadedly connected to a threaded rod 409 rotatably connected to the water collecting box 407, one end of the threaded rod 409 is fixedly connected to a servo motor 410 whose output end is fixedly connected to the threaded rod 409, and the servo motor 410 is started, so that its output end drives the threaded rod 409 to rotate, so that the threaded rod 409 drives the extrusion plate 408 to move inside the water collecting box 407, squeezing the glue inside the water collecting box 407, so that the glue enters the interior of the plug-in slot 404 through the connecting pipe 406, so that the pin 401 is fixedly connected to the fixed plate 402;

[0047] The pin detection mechanism 4 also includes a pushing plate 411 fixedly connected to one end of the moving rod 405, and one side of the pushing plate 411 is fixedly connected to an iron plate 412 corresponding to the movable plate 308. When the movable plate 308 moves, the movable plate 308 slides inside the movable plate 303, so that the movable plate 308 fits against the iron plate 412, pushing the iron plate 412 to move, so that the iron plate 412 drives the moving rod 405 and the fixed plate 402 to move, applying a pulling force to the pin 401, and the interior of the test box 2 is fixedly connected to a support plate 413, and the interior of the support plate 413 is fixedly connected to an electromagnetic coil 414, and one side of the support plate 413 is fixedly connected to an adsorption plate 415 corresponding to the electromagnetic coil 414 and the iron plate 412. When the electromagnetic coil 414 is energized, the adsorption plate 415 generates a magnetic force, which adsorbs the iron plate 412, so that the fixed plate 402 pulls the pin 401 to remain in a fixed position, and the tensile performance of the pin 401 is tested.

[0048] Example 3, based on Example 1 and Example 2, further, a water collecting box 102 is fixedly connected to the upper surface of the supporting base plate 101, a hollow box 103 is fixedly connected to the upper surface of the water collecting box 102, the test box 2 is fixedly connected to the interior of the hollow box 103, and a water inlet pipe 104 connected to the hollow box 103 is fixedly connected to one side of the water collecting box 102. The pure water set in the water collecting box 102 is pumped into the interior of the test box 2 through the cooperation of the existing water pump and the water inlet pipe 104;

[0049] Insert the semiconductor body 301 into the sealed box 403 so that the pins 401 are inserted into the insertion slots 404 on the fixing plate 402. Rotate the magnet block 311 to drive the semiconductor body 301 into the test chamber 2 so that one side of the semiconductor body 301 is aligned with one side of the guide cylinder 306. Using an existing water pump, pure water from the water collection tank 102 is pumped into the test chamber 2 through the water inlet pipe 104, so that the pure water submerges the semiconductor body 301.

[0050] The water collection mechanism 1 also includes a drain pipe 105 fixedly connected to one side of the test box 2. A solenoid valve 106 is installed on the surface of the drain pipe 105. The test box 2 is connected to the hollow box 103 through the drain pipe 105. Through the cooperation between the drain pipe 105 and the solenoid valve 106, when the temperature inside the test box 2 needs to be adjusted, the hot water inside the test box 2 is discharged into the interior of the hollow box 103, and the test box 2 is refilled with water through the water inlet pipe 104, so that hot and cold water are alternately used, the temperature is quickly reduced, and the efficiency of testing the semiconductor body 301 is improved. An electric heating plate 107 is fixedly connected to the inner bottom wall of the test box 2. When the electric heating plate 107 is turned on, it heats the pure water inside the test box 2. This not only allows the temperature of the semiconductor body 301 to be adjusted as needed during testing, so that the semiconductor body 301 can be tested at different temperatures, but also heats the glue, so that the glue can more quickly fix the pin 401 to the fixing plate 402. A water supply pipe is fixedly connected to one side of the water collection box 102.

[0051] Working principle: The semiconductor body 301 is inserted into the sealing box 403 so that the pin 401 is inserted into the insertion slot 404 on the fixing plate 402. The magnet block 311 is rotated to drive the semiconductor body 301 to rotate into the test box 2 so that one side of the semiconductor body 301 is in contact with one side of the guide cylinder 306. Based on the existing water pump, the pure water in the water collection tank 102 enters the test box 2 through the water inlet pipe 104 so that the pure water covers the semiconductor body 301. The driving motor 501 is started so that its output end drives the rotating rod 502 to rotate, thereby causing the rotating disk 503 to drive the flip plate 504 to move through the pin shaft, so that the striking rod 307 moves back and forth inside the guide cylinder 306, so that the striking rod 307 strikes one side of the semiconductor body 301 to test the strength of the semiconductor body 301 packaged device. At the same time, through the setting of pure water, whether bubbles are generated in the pure water is observed to test the airtightness of the semiconductor body 301 packaged device.

[0052] At the same time, during the movement of the striking rod 307, the movable plate 308 is synchronously driven to move, so that the movable plate 308 drives the driving tooth plate 309 to move, so that the driving tooth plate 309 self-engages with the driving gear 305, thereby causing the driving gear 305 to mesh and rotate, driving the linkage tooth plate 304 and the driving tooth plate 309 to move in opposite directions, driving the movable plate 303 to move, and through the setting of bolts, the wire body 302 is fixedly connected to the surface of the movable plate 303, so that the movable plate 303 drives the wire body 302 to move, and the connection between the wire body 302 and the semiconductor body 301 packaging device is tested, and the air tightness of the connection is tested by setting pure water;

[0053] The servo motor 410 is started, and its output end drives the threaded rod 409 to rotate, so that the threaded rod 409 drives the extrusion plate 408 to move inside the water collecting box 407, squeezing the glue inside the water collecting box 407, so that the glue enters the inside of the plug-in slot 404 through the connecting pipe 406, so that the pin 401 is fixedly connected to the fixed plate 402. When the movable plate 308 moves, the movable plate 308 slides inside the movable plate 303, so that the movable plate 308 fits the iron plate 412, pushing the iron plate 412 to move, so that the iron plate 412 drives the movable rod 405 and the fixed plate 402 to move, applying a pulling force to the pin 401. At the same time, the electromagnetic coil 414 is energized, so that the adsorption plate 415 generates a magnetic force, which adsorbs the iron plate 412, so that the fixed plate 402 pulls the pin 401 to remain in a fixed position, and the tensile performance of the pin 401 is tested.

[0054] When testing the semiconductor body 301, the electric heating plate 107 is started as needed to heat the pure water inside the test box 2. This not only allows the temperature of the semiconductor body 301 to be adjusted as needed during testing, so that the semiconductor body 301 can be tested at different temperatures, but also heats the glue so that the glue can fix the pin 401 and the fixing plate 402 more quickly.
