Description

Technical Field

[0001] The invention belongs to the technical field of semiconductor plastic package strength testing, in particular to a semiconductor plastic package strength testing device. Background Art

[0002] Semiconductor plastic package refers to the plastic packaging material used to protect the chip and its lead frame during the semiconductor device packaging process. Before chip production, the plastic package needs to be strength tested to meet the usage requirements of different chips.

[0003] The existing impact strength test is to use a falling hammer to freely fall from a certain height to directly impact the plastic package, and then use laser detectors and other equipment to observe whether the plastic package is broken and deformed, so as to evaluate the impact strength of the plastic package. Before the test starts, the distance between the test bench and the falling hammer position needs to be adjusted to an appropriate value according to the properties of the plastic package, and then the plastic package is tested. In the process of testing different batches of plastic packages, the thickness of different plastic packages will be inconsistent, which will cause the impact force exerted by the falling hammer on plastic packages of different thicknesses to be inconsistent. In order to ensure the accuracy of the test results, it is often necessary to adjust the distance between the test bench and the falling hammer. However, the height of the test bench of the existing testing device cannot be adjusted, and only the height of the falling hammer can be adjusted separately. In order to achieve the effect of testing plastic packages of different thicknesses, the position of the falling hammer needs to be repeatedly adjusted. In this way, the test time will be extended, thereby reducing the efficiency of the test. At the same time, if the position of the falling hammer is not adjusted accurately, the test value will be deviated, resulting in inaccurate test results, which will cause unqualified products to enter the market.

The two lower pressing frames 403 move toward each other. When the symmetrically distributed rollers 406 contact each other, the transfer member 404 reaches the adjacent first limiting plate When the lower pressure frame 403 contacts the plastic sealing body, the lower pressure frame 403 drives the plastic sealing body to move downward, and the plastic sealing body drives the containing plate 3, the supporting rod 9 and the spline rod 10 to move downward and squeeze the liquid in the upper chamber of the first sleeve 2. The liquid in the upper chamber of the first sleeve 2 enters its own lower chamber through the one-way valve in the second pipe 502 and is located at the lower side of the second floating plug 12, and the first elastic member is stretched.

[0029] During the downward movement of the transfer member 404, when the transfer member 404 reaches the lower side of the vertical portion of the adjacent first limit plate 407, the driving motor 4 starts to rotate in the opposite direction and moves the movable plate 7 upward. The movable plate 7 drives the Z-shaped rod 401, the lower pressure frame 403, the transfer member 404 and the roller 406 to move upward. The lower pressure frame 403 loses contact with the plastic sealing body. Under the action of the one-way valve in the first pipeline 501, the liquid in the lower chamber of the first sleeve 2 cannot flow along the second pipeline 502. At the same time, under the blocking action of the blocking slide bar 509, the liquid in the chamber of the first sleeve 2 cannot move along the first pipeline 501 into the upper chamber, so that the first floating plug 11 and the parts connected thereto cannot move, thereby making the plastic sealing body unable to move. The symmetrically distributed transfer member 404 is located between the adjacent seventh elastic member 407 and the lower pressure frame 403. Under the action of the elastic force of the elastic member, they move back to each other, and the transfer member 404 drives the adjacent lower pressure frame 403 and the roller 406 thereon to move through the adjacent sixth elastic member, and the symmetrically distributed rollers 406 lose contact with each other. When the transfer member 404 loses contact with the adjacent first limit plate 407, the symmetrically distributed transfer member 404 and the parts thereon complete the reset, and as the Z-shaped rod 401 continues to move upward, when the Z-shaped rod 401 contacts the one-way block 309, the Z-shaped rod 401 drives the one-way block 309 and the parts connected thereto to move synchronously upward, when the Z-shaped rod 401 contacts the blocking block 304 and is squeezed by it, the symmetrically distributed Z-shaped rods 401 move back to each other, and the Z-shaped rod 401 drives the adjacent lower pressure frame 403, the transfer member 404 and the roller 406 to move, and the fifth elastic member is stretched.

[0030] During the rising process of the Z-shaped rod 401, when the Z-shaped rod 401 is on the vertical surface of the blocking block 304, the distance between the two Z-shaped rods 401 is the largest, the Z-shaped rod 401 loses contact with the adjacent one-way block 309, and the impact member 5 moves downward under the combined action of the elastic force of the second elastic member and gravity. When the sliding block 308 contacts the first limit member 303, the sliding block 308 and the parts connected thereto stop moving. When the moving plate 7 is about to contact the second limit member 306, the moving plate 7 contacts and squeezes the blocking long rod 505, and the blocking long rod 505 moves forward, and the blocking long rod 505 drives the limit member 306 to move forward. The sliding plate 504 moves, the eighth elastic member is stretched, and the long blocking rod 505 begins to block the first pipe 501 and the second pipe 502. When the long blocking rod 505 completely blocks the first pipe 501 and the second pipe 502, the movable plate 7 contacts and squeezes the second limiting member 306, and the second limiting member 306 moves forward. The movement of the second limiting member 306 increases the volume of the space on the rear side of the third sleeve 305, and negative pressure is generated on the rear side of the third sleeve 305. The negative pressure drives the liquid in the second sleeve 302 to move into the third sleeve 305 and then drives the first limiting member 303 to move forward, and the third elastic member is stretched.

[0031] During the upward movement of the movable plate 7, when the second limit member 306 loses contact with the inclined surface of the movable plate 7, the driving motor 4 stops rotating, the first limit member 303 loses contact with the sliding block 308, and the impact member 5 moves downward under the combined action of the elastic force of the second elastic member and gravity, and the impact member 5 drives the sliding block 308 to move synchronously. When the sliding block 308 loses contact with the third limit member 512, the ninth elastic member retracts and drives the third limit member 512 to extend forward, and the spatial volume of the rear side of the third limit member 512 and the fifth sleeve 511 increases and generates negative pressure. The negative pressure causes the liquid in the fourth sleeve 508 to move into the fifth sleeve 511 and drives the blocking slide bar 509 to move to the right, and the blocking slide bar 509 releases the blockage of the first pipe 501.

[0032] During the downward movement of the impact member 5, when the force-applying plate 203 loses contact with the force-bearing circular plate on the impact member 5, the second elastic member is reset under the action of the elastic force, and when the impact member 5 contacts the plastic-sealed body on the receiving plate 3 and applies an impact force, the internal liquid in the upper and lower chambers of the first sleeve 2 cannot move due to the restriction of the sealing long rod 505, so that the impact member 5 applies an impact force to the plastic-sealed body on the receiving plate 3. At this time, the impact test of the impact member 5 on the plastic-sealed body on the receiving plate 3 is completed.

[0033] When the impact member 5 completes the impact test on the plastic package on the holding plate 3, the control terminal on the C-shaped frame 1 turns on the drive motor 4, the drive motor 4 rotates forward and causes the movable plate 7 to move downward, and when the movable plate 7 loses contact with the second limiting member 306, the third elastic member resets and drives the second limiting member 306 to move backward, and the second limiting member 306 causes the liquid in the third sleeve 305 to move into the second sleeve 302, and the liquid in the second sleeve 302 drives the first limiting member 303 to reset, and when the movable plate 7 loses contact with the blocking long rod 505, the eighth elastic member retracts, and when the first Under the action of the pulling force of the eighth elastic member, the blocking long rod 505 moves backward, and the blocking long rod 505 releases the blocking of the first pipe 501 and the second pipe 502. The upper chamber and the lower chamber of the first sleeve 2 are connected to each other, and the first elastic member begins to reset. The second floating plug 12 moves downward under the action of the pulling force, and the liquid in the lower chamber of the first sleeve 2 enters its own upper chamber through the second pipe 501. The liquid in the upper chamber of the first sleeve 2 causes the first floating plug 11 and its connecting parts to move upward, and the containing plate 3 drives the plastic sealing body and the impact member 5 to move upward, and the liquid in the first sleeve 2 completes the reset.

[0034] The movable plate 7 descends and gradually loses contact with the blocking block 304, and the two Z-shaped rods 401 move toward each other. When the Z-shaped rod 401 loses contact with the blocking block 304, the fifth elastic member is reset. As the movable plate 7 moves downward, the Z-shaped rod 401 drives the parts connected thereto to move downward and contact the upper side of the one-way block 309. The Z-shaped rod 401 squeezes the one-way block 309 to deflect it downward, and the fourth elastic member is twisted until the Z-shaped rod 401 passes. When the Z-shaped rod 401 loses contact with the one-way block 309, the one-way block 309 is reset under the action of the fourth elastic member. When the intermediate transfer member 404 contacts and squeezes the first limiting plate 407 When the roller 406 contacts the mounting plate of the impact piece 5 and stops moving, the sixth elastic piece is compressed, and the action of the liquid in the first sleeve 2 when the plastic package body is pressed down is repeated. When the sixth elastic piece is compressed to the limit position, when the one-way block 309 is reset, the control terminal on the C-shaped frame 1 reverses the drive motor 4, and the drive motor 4 reverses to move the movable plate 7 and its connecting parts upward, and the Z-shaped rod 401 contacts the lower side of the one-way block 309, and the Z-shaped rod 401 drives the one-way block 309 and all the synchronously upward moving parts thereon to move upward, and the impact piece 5 is out of contact with the plastic package body.

[0035] When the Z-shaped rod 401 contacts the blocking block 304, the sliding block 308 starts to contact and squeeze the third limiting member 512, and the third limiting member 512 moves backward to make the liquid in the fifth sleeve 511 move into the fourth sleeve 508, the ninth elastic member is stretched, and the liquid in the fourth sleeve 508 makes the blocking sliding rod 509 move leftward. When the blocking sliding rod 509 completely blocks the second pipe 501, the reset of the impact member 5 is completed. At the same time, when the Z-shaped rod 401 contacts the blocking block 304, the Z-shaped rod 401 repeats the above-mentioned back movement of itself. The force plate 203 contacts the force-bearing circular plate on the impact member 5 and moves upward, the second elastic member is compressed, and in the process of the one-way block 309 driving the sliding block 308 to move upward, when the sliding block 308 contacts the first limiting member 303, the sliding block 308 squeezes the first limiting member 303 to move forward, and the first limiting member 303 causes the liquid in the second sleeve 302 to move into the third sleeve 305 and drives the second limiting member 306 to move forward, the third elastic member is stretched, and when the sliding block 308 loses contact with the first limiting member 303 When the first stopper 303 is extended and located at the lower side of the sliding block 308, the above-mentioned reset action of the first stopper 303 is repeated. When the Z-shaped rod 401 contacts the inclined surface of the blocking block 304, the above-mentioned opening action of the Z-shaped rod 401 is repeated. When the Z-shaped rod 401 loses contact with the lower side of the one-way block 309, the impact member 5 moves downward under the combined action of the elastic force of the second elastic member and gravity. The sliding block 308 stops moving after contacting the upper side of the first stopper 303. Then the control terminal on the C-shaped frame 1 makes the drive motor 4 rotate forward, and the drive motor 4 rotates forward. The machine 4 causes the movable plate 7 and its connecting parts to move downward, and the Z-shaped rod 401 is gradually reset under the action of the fifth elastic member. When the Z-shaped rod 401 contacts the upper side of the one-way block 309, the above-mentioned action through the one-way block 309 is repeated, and the movable plate 7 and its connecting parts are restored to their initial positions. Then, the control terminal on the C-shaped frame 1 causes the electric push rod 201 to drive the lower pressure plate 202 to reset, thereby restoring the second elastic member between the force plate 203 and the lower pressure plate 202 to its initial working state. The staff closes the device and removes the plastic package, completing the use of the device this time.

The tenth sleeve 807 and the ninth sleeve 805 slide on the adjacent slide grooves on the first sleeve 2 respectively. The tenth sleeve 807 is connected to the eighth sleeve 802 through a soft pipe. Through the movement of the T-shaped clamping rod 710, the third slide bar 803 is extended forward a specified distance, and then the size of the plastic package body is detected.

[0038] like Fig.13 and Fig.14As shown, the impact plate adjustment assembly includes a first shell 901, the first shell 901 is slidably connected to the mounting plate of the impact member 5, the impact member 5 is slidably connected to the second shell 902, the upper side of the second shell 902 and the upper side of the first shell 901 are fixedly connected with a second limit plate 903, the second limit plate 903 is limitedly matched with the impact member 5, the second limit plate 903 is slidably connected to the impact member 5, the second limit plate 903 is extruded and matched with the third slide bar 803, a limited anti-rotation plate 904 is fixedly connected to the mounting plate on the impact member 5, a limited anti-rotation rod 905 is fixedly connected to the upper side of the limited anti-rotation plate 904, the limited anti-rotation rod 905 is slidably connected with two symmetrically distributed inclined telescopic cylinders 906, an eleventh elastic member is fixedly connected between the inclined telescopic cylinder 906 and the limited anti-rotation rod 905, the eleventh elastic member is a spring, the inclined telescopic cylinder 906 is slidably connected with a telescopic inclined plane 908, and the telescopic inclined plane 908 is connected to the adjacent first The two limiting plates 903 are matched to limit the positions of the second shell 902 and the first shell 901. A twelfth elastic member is fixedly connected between the telescopic inclined surface 908 and the adjacent inclined telescopic cylinder 906. The twelfth elastic member is a spring. The extrusion force of the telescopic inclined surface 908 on the adjacent second limiting plate 903 is greater than the impact force of the impact member 5 on the plastic package body. A reset rod 910 is fixedly connected to the upper side of the C-shaped frame 1. The inclined telescopic cylinder 906 is extruded and matched with the inclined surface of the reset rod 910. The second shell 902 and the first shell 901 are located at different heights by moving the third sliding bar 803. The unidirectionality of the telescopic inclined surface 908 is used to control the impact cross section of the device. The lower side surfaces of the first shell 901 and the second shell 902 are flush with the lower side surface of the impact member 5, ensuring that the first shell 901, the second shell 902 and the impact member 5 fit with the upper surface of the plastic package body, so that the plastic package body is evenly stressed.

[0039] When the movable plate 7 and its connecting parts move downward, the movable plate 7 drives the first slide bar 702 to move synchronously and moves the liquid in the sixth sleeve 701 into the seventh sleeve 703. The liquid in the seventh sleeve 703 causes the second slide bar 704 to move to the right. The second slide bar 704 drives the rack 705 to move synchronously. The rack 705 drives the gear 706 to rotate. The gear 706 drives the spline rod 10 and the rotating plate 708 connected thereto to rotate synchronously. The rotating plate 708 squeezes the adjacent rotating rod 709 through the arc groove thereon. The rotating rod 709 and the adjacent T-clamping rod slide along the straight groove of the adjacent holding plate 3. The circumferentially distributed T-clamping rods move toward each other, thereby clamping the plastic sealing body to complete the centering of the plastic sealing body. When all the T-clamping rods 710 contact the plastic sealing body, the T-clamping rod 710 stops moving, the rotating rod 709 continues to move, and the adjacent tenth elastic member is stretched.

[0040] When the movable plate 7 and its connecting parts complete the action of pressing down the plastic package body, the rotating rod 709 reaches the position close to the center of the arc groove of the rotating plate 708. When the driving motor 4 rotates in the opposite direction to make the movable plate 7 move upward, the movable plate 7 drives the first slide bar 702 to move synchronously and increases the volume of the lower side of the sixth sleeve 701 to generate negative pressure. The negative pressure causes the liquid in the seventh sleeve 703 to move into the sixth sleeve 701. The liquid in the seventh sleeve 703 causes the second slide bar 704 to move to the left. The second slide bar 704 drives the rack 705 to move to the left. The rack 705 drives the gear 706 to rotate in the opposite direction. The gear 706 drives the spline rod 10 and the rotating plate 708 connected thereto to rotate synchronously. The rotating plate 708 squeezes the adjacent rotating rod 709 through the arc groove thereon, and the rotating rod 709 and the adjacent T-shaped clamping rod slide along the adjacent straight groove of the holding plate 3, and the circumferentially distributed T-shaped clamping rods move in opposite directions, and the rotating rod 709 drives the adjacent T-shaped clamping rod 710 to move. During the upward movement of the movable plate 7, when the movable plate 7 loses contact with the inclined surface of the second limit member 306, the rotating rod 709 and the adjacent T-shaped clamping rod 710 respectively reach the extreme positions away from the center of the adjacent arc groove of the rotating plate 708 and the adjacent straight groove of the holding plate 3. When the movable plate 7 and its connecting parts return to the initial position, the rotating rod 709 and the T-shaped clamping rod 710 also complete the reset.

[0041] During the opposite movement of the circumferentially distributed T-shaped clamping rods 710, the rear T-shaped clamping rod 710 drives the fourth slide bar 804 to move synchronously, and the left T-shaped clamping rod 710 drives the fifth slide bar 806 to move synchronously. The movement of the fourth slide bar 804 and the fifth slide bar 806 respectively forms negative pressure in the ninth sleeve 805 and the tenth sleeve 807, thereby causing the ninth sleeve 805 and the tenth sleeve 807 to extract the liquid in the eighth sleeve 802, and the liquid in the eighth sleeve 802 is reduced, so that the third slide bar 803 moves to the front side. When the area of ​​the plastic package body is smaller than the sum of the areas of the impact plate of the impact member 5, the first shell 901 and the second shell 902, the eighth slide bar 803 moves to the front side. The rod contacts and squeezes the second limit plate 903 near the rear side, and the second limit plate 903 near the rear side moves upward under the squeezing of the third sliding rod 803, and the second limit plate 903 near the rear side drives the second shell 902 to move upward, and the second limit plate 903 near the rear side contacts and squeezes the adjacent telescopic inclined surface 908 and moves it to the right, and the twelfth elastic member is compressed. When the second limit plate 903 at the rear side loses contact with the adjacent telescopic inclined surface 908, the telescopic inclined surface 908 is reset under the elastic force of the twelfth elastic member, so that the telescopic inclined surface 908 is located below the second limit plate 903 at the rear side, and the twelfth elastic member returns to its initial state.

[0042] When the area of ​​the plastic sealing body is smaller than the sum of the areas of the impact plate of the impact piece 5 and the first shell 901, when the third slide bar 803 continues to move forward, the second limit plate 903 near the front side moves upward and drives the first shell 901 thereon to move, the second limit plate 903 near the front side contacts and squeezes the adjacent telescopic inclined surface 908 and moves it to the right, the twelfth elastic member is compressed, and when the second limit plate 903 loses contact with the adjacent telescopic inclined surface 908, the telescopic inclined surface 908 is reset under the action of the elastic force of the twelfth elastic member, and the twelfth elastic member returns to its initial state, and when the T-shaped clamping rod 710 loses contact with the plastic sealing body, the T-shaped clamping rod 710 drives the fourth slide bar 804 and the fifth slide bar 806 to reset and move, the fourth slide bar 804 and the fifth slide bar 806 squeeze the liquid in the ninth sleeve 805 and the tenth sleeve 807 respectively, so that the liquid enters the eighth sleeve 802 through the adjacent soft pipe, and the liquid in the eighth sleeve 802 drives The third slide bar 803 moves backward, and when the third slide bar 803 loses contact with the two parallel second limit plates 903, the two parallel second limit plates 903 start to move under the action of gravity, and the two parallel second limit plates 903 stop moving respectively under the limit of the adjacent telescopic inclined planes 908, and the area of ​​the plastic package body is detected by moving the T-shaped clamping rod 710, so that the third slide bar 803 moves accordingly, and the impact area of ​​the plastic package body by the impact member 5 is controlled, and the size adjustment of the impact section of the device is completed at this time, and when the movable plate 7 moves for the second time to reach the Z-shaped rod 401 and contacts the vertical surface of the blocking block 304, the symmetrically distributed inclined telescopic cylinders 906 move back to each other under the extrusion of the reset rod 910, and the eleventh elastic member is compressed, and the two parallel second limit plates 903 lose the limit of the adjacent telescopic inclined planes 908, and the two parallel second limit plates 903 return to the initial position, completing the automatic detection and adjustment of the impact section size function of the device.
