Description

Technical Field

[0001] The present invention relates to the technical field of packaged chip detection, and particularly to a packaged chip detection device. Background Art

[0002] In the current era of rapid technological development, chips have been widely penetrated into all aspects of people's lives and numerous industries, becoming the core driving force for promoting the digital and intelligent transformation of society. From daily used smartphones, tablets, and smart home devices to key fields such as communication, medical, transportation, and aerospace that are related to national economy and people's livelihood, the performance and reliability of chips directly affect the stable operation of the entire electronic system.

[0003] As an important link in the chip industrial chain, packaged chips physically encapsulate chip die, while protecting the internal precision circuit structure, and also establishing an effective electrical connection and signal interaction channel between the chip and the external circuit board. Therefore, strict and comprehensive quality detection of packaged chips is a key step to ensure the high-quality use of chips.

[0004] In the quality detection work of packaged chips, temperature cycle testing occupies an extremely important position. In actual application scenarios, chips often face complex and changeable temperature environments. For example, in different geographical regions, different seasons, and different working states of electronic products, the internal chips need to withstand frequent changes from low temperature to high temperature and always maintain stable and reliable performance. Traditional temperature cycle testing equipment and methods have many deficiencies. On the one hand, many existing devices are difficult to accurately and quickly achieve uniform heating and cooling of the whole chip, resulting in differences in the temperature changes experienced by different parts of the chip during the test, unable to realistically simulate the real temperature environment faced during actual use, and thus affecting the accurate assessment of the chip's temperature change tolerance and reliability; on the other hand, most of the past detection means can only view the chip state from a single angle or a limited perspective when observing the chip state, making it difficult to comprehensively and intuitively observe the situations of different positions such as both sides of the packaged chip, and making it easy to overlook some subtle appearance defects (such as tiny cracks in the package due to temperature stress, potential problems at the joint of the pin and the package, etc.), reducing the accuracy and effectiveness of the detection.

[0005] In addition, with the continuous advancement of the electronics manufacturing industry towards large-scale and high-efficiency production models, the requirements for the automation level, function integration, and coordinated cooperation between various functional modules of the detection equipment are also increasing day by day. Traditional packaged chip detection often relies on multiple scattered devices to separately complete different detection items, or manual operations to assist in completing some detection links, which not only consumes a large amount of human, material, and time costs, but also is prone to human errors, making it difficult to meet the dual high standards of detection efficiency and detection quality required by modern industrial production.

[0022] Compared with the prior art, the functional modules of the detection device of the present invention are relatively independent and closely related, facilitating later maintenance and servicing work. Moreover, this modular design concept also provides convenient conditions for the subsequent upgrading and transformation of the device. With the continuous development of chip detection technology and the emergence of new detection requirements, it is relatively easy to improve a certain functional module in the device or add new functional modules, extending the service life of the device.

The opposite sides of the two threaded rods 6 are fixedly connected to the driven parts of the corresponding pneumatic clutch 4.

The two rotating rods 10 are connected to the corresponding short rods 5 through the first transmission assembly 7. The first transmission assembly 7 includes a first sprocket arranged on the short rod 5 and the rotating rod 10. The two first sprockets are connected by a first chain transmission.

[0035] Among them, the rectangular plate 22 located on the left side is conductive, and two fixed plates 25 are fixedly connected to the left inner wall of the detection box 1.

A second electromagnet 37 is provided on the side of multiple rectangular grooves 41 away from the placement opening 40, and a block 39 is slidably connected in the multiple rectangular grooves 41. Multiple blocks 39 are elastically connected to the adjacent sides of the corresponding second electromagnet 37 through a second spring 38. Two conductive rods are symmetrically fixedly connected to the cross bar 17 on the right side, and two contact pieces are provided on the right inner wall of the rectangular box 14. The two conductive rods and the two contact pieces constitute two conductive components. The external power supply, the two conductive components and the multiple second electromagnets 37 form a loop through wires. The conductive component and the corresponding two second electromagnets 37 are connected in series in the loop, and the two series circuits are connected in parallel in the loop.

[0037] Among them, the inner top and inner bottom of the detection box 1 are fixedly connected with multiple fixed blocks 23, and the adjacent sides of every two matching fixed blocks 23 are connected to the swing rod 33 for common rotation, and the multiple swing rods 33 are fixedly connected with hollow plates 24, and the multiple hollow plates 24 are provided with nozzles on one side close to the placement box 36, and the multiple hollow plates 24 are connected with hoses. A swing assembly is provided in the detection box 1, and the swing assembly includes a strip box 27 fixed to the front side of the upper fixed block 23, and the front side of the swing rod 33 located above extends into the strip box 27 and is fixedly connected to the second gear 32. The left inner wall of the strip box 27 is provided with a first electromagnet 28, and the strip box 27 is slidably connected with a slider 30, and the slider 30 is connected to the first The adjacent sides of the electromagnet 28 are elastically connected by a first spring 29, and a second rack 31 is fixedly connected to the right side of the slider 30. The slider 30 is conductive, and a second conductive sheet is provided on the inner wall of the rear side of the strip box 27. The external power supply, the rectangular plate 22, the two first conductive sheets, the second conductive sheet, the slider 30 and the first electromagnet 28 form a loop through wires. Multiple swing rods 33 are connected through a third transmission assembly 35. The third transmission assembly 35 includes a third sprocket arranged on multiple swing rods 33. Multiple third sprockets are connected through a third chain transmission. The hollow plates 24 located at the upper right and lower left are in an inclined state in the initial state, and the hollow plates 24 located at the upper left and lower right are in a vertical state in the initial state.

[0038] The functional principle of the present invention can be explained through the following operation mode: when testing the packaged chip, the sliding door 2 is opened. At this time, since the conductive rod located at the top contacts the two contact pieces, the two second electromagnets 37 located at the top are in an energized state, and the two second electromagnets 37 located at the bottom are in an energized state. At this time, the stopper 39 located at the top is located in the corresponding rectangular groove 41, and the stopper 39 located at the bottom is located in the placement opening 40. At this time, the staff can place the packaged chip in the placement opening 40;

[0039] After the encapsulated chip is placed, the staff closes the sliding door 2 and controls the two pneumatic rods 16 to first contract and then stretch. During the stretching and contracting process of the pneumatic rods 16, the first rack 19 is driven by the moving block 15 to first move upward and then downward, so that the placement box 36 and the encapsulated chip are driven by the cross bar 17 to first rotate counterclockwise and then clockwise. At this time, the staff can observe the appearance of the chip through the vision sensor 34;

[0040] When the appearance of the chip is normal, the staff controls the pneumatic clutch 4 to operate, so that the two groups of teeth on the pneumatic clutch 4 are engaged. Then the staff controls the driving motor 9 to operate. At this time, the operation of the driving motor 9 drives the transmission rod 13 and the short rod 5 to rotate through the first transmission component 7 and the second transmission component 11. At this time, the rotation of the two short rods 5 drives the threaded rod 6 to rotate through the pneumatic clutch 4. At the same time, the operation of the driving motor 9 drives the two rotating rods 10 to rotate, so that the two third gears 42 rotate, thereby driving the two cylinders 20 to rotate. At the same time, the rotation of the two threaded rods 6 causes the two rectangular plates 22 to move relative to each other, and then pushes the two cylinders 20 to move relative to each other, so that the placement box 36 and the detection chip are located inside the two cylinders 20;

[0041] When the adjacent sides of the two cylinders 20 come into contact, at this time, the rectangular plate 22 on the left contacts the two conductive blocks 26, causing multiple electric heating plates to operate. Since the two cylinders 20 are in a rotating state, the chip is uniformly heated;

[0042] It is worth mentioning that when the two cylinders 20 move to the specified position, the staff controls the two groups of teeth on the pneumatic clutch 4 to separate. At this time, the operation of the driving motor 9 only drives the rotating rod 10 and the short rod 5 to rotate, and the threaded rod 6 no longer rotates;

[0043] After heating the chip for a period of time, the staff controls the two groups of teeth on the pneumatic clutch 4 to engage again, and at the same time controls the output shaft of the driving motor 9 to rotate counterclockwise, so that the two rectangular plates 22 drive the two cylinders 20 to move away from each other, exposing the encapsulated chip. During each detection, an external blower is set. After connecting multiple hoses to the intake end of the external blower, the staff controls the external blower to operate after each time the two cylinders 20 move away from each other and reset, so that the cold air flow cools the upper and lower sides of the encapsulated chip;

[0044] After heating and cooling the chip multiple times, the staff can use the vision sensor 34 and the flipping component to detect the encapsulated chip again, so as to more reliably evaluate the stability and reliability of the chip under different temperature conditions.

[0045] After each reset of the cylinder 20, the rectangular plate 22 located on the left side at this time contacts the two first conductive sheets. At this time, since the slider 30 contacts the second conductive sheet, the first electromagnet 28 is energized. After the first electromagnet 28 is energized, it generates an attractive force on the slider 30, causing the slider 30 to drive the second rack 31 to move leftward. When the slider 30 moves leftward and separates from the second conductive sheet, due to inertia, the slider 30 drives the second rack 31 to move leftward again for a certain distance, and then under the elastic action of the first spring 29, the slider 30 drives the second rack 31 to move back to its original position. When the slider 30 contacts the second conductive sheet again, the above process will be repeated, thereby causing multiple hollow plates 24 to be in a swinging state, so that the chip can be quickly cooled at each position.

[0046] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
