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 era of rapid technological development today, chips have been widely penetrated into all aspects of people's lives and many industries, becoming the core driving force for promoting the digital and intelligent transformation of society. From daily used smartphones, tablets, smart home devices to key fields such as communication, medical treatment, transportation, aerospace, etc. 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 part of 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 that chips can be put into use with high quality.

[0004] In the quality detection work of packaged chips, the temperature cycle test plays an extremely important role. In the actual application scenarios of chips, they 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 test 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, and cannot truthfully simulate the real temperature environment faced during actual use, thus affecting the accurate evaluation of the chip's tolerance to temperature changes and reliability; on the other hand, when observing the chip state with past detection means, most can only view from a single angle or a limited perspective, and it is very difficult to comprehensively and intuitively observe the situations of different positions such as both sides of the packaged chip, making it easy to overlook some subtle appearance defects (such as tiny cracks in the package due to temperature stress, potential problems at the junction of the pins and the package, etc.), reducing the accuracy and effectiveness of 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 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 manually assist in completing some detection links.

[0026] 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 rotatably connected with a swing rod 33. 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. The multiple hollow plates 24 are connected with hoses. A swing component is provided in the detection box 1, and the swing component includes a strip box 27 fixed to the front side of the upper fixed block 23. The front side of the swing rod 33 located above extends into the strip box 27 and is fixedly connected with a second gear 32. The left inner wall of the strip box 27 is provided with a first electromagnet 28. A slider 30 is slidably connected in the strip box 27, and the slider 30 is connected to the first The adjacent sides of the electromagnet 28 are elastically connected by the first spring 29, and the second rack 31 is fixedly connected to the right side of the slider 30. The slider 30 is conductive. The rear inner wall of the strip box 27 is provided with a second conductive sheet. 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 the multiple swing rods 33. The 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.

[0027] The present invention can explain its functional principle through the following operation mode: when testing the packaged chip, the sliding door 2 is opened. At this time, the conductive rod located at the top contacts the two contact pieces, so that the two second electromagnets 37 located at the top are in a powered-on state, and the two second electromagnets 37 located at the bottom are in a powered-off 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; 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; 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 assembly 7 and the second transmission assembly 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, thus driving the two cylinders 20 to rotate. At the same time, the rotation of the two threaded rods 6 makes the two rectangular plates 22 move relatively, and then pushes the two cylinders 20 to move relatively, so that the placement box 36 and the test chip are located in the two cylinders 20; When the adjacent sides of the two cylinders 20 come into contact, the rectangular plate 22 on the left side contacts the two conductive blocks 26 at this time, so that a plurality of electric heating plates operate. Since the two cylinders 20 are in a rotating state, the chip is uniformly heated; 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; 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 fan is set. After connecting a plurality of hoses to the air inlet end of the external fan, the staff controls the external fan 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; After heating and cooling the chip multiple times, the staff can use the vision sensor 34 and the flipping assembly to detect the encapsulated chip again, so as to more reliably evaluate the stability and reliability of the chip under different temperature conditions.

[0028] 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 the plurality of hollow plates 24 to be in a swinging state, so that the chip can be quickly cooled at each position.

[0029] 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.
