Description

Technical Field

[0001] This utility model relates to the field of chip testing technology, specifically to an integrated circuit chip welding strength testing component. Background Technology

[0002] With the rapid development of microelectronics technology, integrated circuit chips, as the core components of modern electronic devices, face increasingly higher requirements for performance, reliability, and integration. In the packaging and assembly process of integrated circuit chips, the soldering connection between the chip and the substrate is a crucial step in ensuring electrical conductivity, signal transmission, and heat conduction. The soldering quality directly affects the electrical performance and operational stability of the chip; therefore, effective and reliable testing and evaluation of the soldering strength of integrated circuit chips are necessary.

[0003] Currently, the main testing methods for the soldering strength of integrated circuit chips in the industry include shear testing and pull-out testing. Shear testing is the most widely used method, which usually requires a push-pull force testing machine. This testing machine is equipped with a high-precision force sensor, a precision XYZ three-axis motion platform, an optical microscope, and a dedicated shearing component. The shearing component is usually a rigid pusher. The machine controls the pusher to apply a push force to the side of the chip at a constant speed in a direction parallel to the chip mounting plane until the solder joint is sheared and broken. The shearing strength is calculated by recording the maximum push force value.

[0004] However, the push blades used in traditional testing instruments are typically custom-designed for chips of specific sizes or package types. Before testing, to ensure that the shearing force is applied evenly to the chip, operators need to manually replace the push blade with a matching one based on the size and model of the chip under test. This process is cumbersome, inconvenient to install and remove, and time-consuming, thus extending test preparation time, reducing testing efficiency, and increasing management complexity due to the need to manage multiple push blades. Therefore, to solve the above-mentioned problems, an integrated circuit chip soldering strength testing component is provided. Utility Model Content

[0005] This invention provides an integrated circuit chip welding strength testing component. By activating a servo motor, it can quickly match the pusher blade, thereby rapidly meeting the testing requirements of chips of different models and sizes, and solving the problem mentioned in the background art where workers cannot quickly match the pusher blade.

[0006] This utility model provides the following technical solution: An integrated circuit chip welding strength testing assembly includes a housing with an open bottom and a turntable installed inside the housing. The turntable has multiple push blades arranged in a ring at equal intervals. The housing has an adjustment part for driving the multiple push blades to rotate and switch sequentially along the axis of the turntable.

[0007] As a preferred embodiment of this utility model, the adjusting part includes a rotating rod rotatably connected inside the housing, a servo motor fixedly installed inside the housing, a worm gear fixedly connected to the rotating rod, a worm meshing with the worm gear fixedly connected to the output end of the servo motor, and a turntable fixedly connected to the rotating rod.

[0008] As a preferred technical solution of this utility model, a plurality of female sleeves are fixedly connected in a ring at equal intervals on the turntable, and a male head is fixedly connected to one end of the pusher. The male head is inserted into the female sleeve, and the female sleeve is provided with a positioning member for fixing the male head.

[0009] As a preferred embodiment of this utility model, the positioning component includes a movable ring slidably sleeved on the female sleeve, with a gap formed between the movable ring and the female sleeve. A spring is sleeved on the female sleeve, with the spring located in the gap. The two ends of the spring are fixedly connected to the protruding surfaces of the female sleeve and the movable ring, respectively. The female sleeve has multiple through holes in a ring shape, and a positioning ball is slidably installed in each through hole. A slot is formed on the male end, and when the male end is inserted into the female sleeve, the positioning ball is engaged in the slot.

[0010] As a preferred embodiment of this utility model, the diameter of the positioning ball is larger than the diameter of the through hole located at one end of the inner wall of the female sleeve, and the diameter of the positioning ball is smaller than the diameter of the through hole located at one end of the outer wall of the female sleeve.

[0011] As a preferred embodiment of this utility model, a support plate is fixedly connected inside the outer shell, and the rotating rod is rotatably connected to the support plate.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Reference Figures 1-6An integrated circuit chip welding strength testing assembly includes a housing 1 fixedly mounted on a push-pull force testing machine, with an open bottom. It also includes a turntable 2 installed inside the housing 1. The turntable 2 has multiple push blades 3 of different sizes arranged in a ring at equal intervals. The number of push blades 3 ranges from 4 to 12; this assembly preferably uses 6. An adjustment section is provided inside the housing 1, which drives the multiple push blades 3 to rotate sequentially along the axis of the turntable 2. The open bottom of the housing 1 allows the push blades 3 to smoothly cut out from inside the housing 1 and move towards the circuit core.

[0019] Specifically, through the adjustment unit, multiple pusher blades 3 of different sizes and specifications can be switched sequentially to achieve rapid matching of pusher blades 3. This can quickly meet the testing needs of chips of different models and sizes. The multi-station design greatly reduces the frequency of workers disassembling and replacing pusher blades 3 and reduces test preparation time. This not only helps to improve testing efficiency, but also facilitates the management and use of pusher blades 3.

[0020] Of course, in other embodiments, the adjustment unit includes a rotating rod 4 rotatably connected inside the housing 1. A servo motor 41, which can be a Panasonic A6 series or Schneider Electric LXM32, is fixedly installed inside the housing 1. A worm gear 42 is fixedly connected to the rotating rod 4. A worm 43 that meshes with the worm gear 42 is fixedly connected to the output end of the servo motor 41. A turntable 2 is fixedly connected to the rotating rod 4. A support plate 8 is fixedly connected inside the housing 1. The rotating rod 4 is rotatably connected to the support plate 8 to provide auxiliary support for the rotating rod 4 and improve its rotational stability.

[0021] Specifically, during use, by starting the servo motor 41, the worm gear 43, worm wheel 42, and rotating rod 4 are driven to rotate, and the turntable 2 rotates 60° each time. This allows for sequential switching of multiple pusher blades 3 of different sizes and specifications, enabling rapid matching of the pusher blades 3. This can quickly meet the testing needs of chips of different models and sizes. The multi-station design greatly reduces the frequency of workers disassembling and replacing the pusher blades 3, reducing test preparation time. This not only helps improve testing efficiency but also facilitates the management and use of the pusher blades 3.

[0022] The aforementioned turntable 2 has multiple female sleeves 5 fixedly connected in a ring at equal intervals. One end of the pusher 3 is fixedly connected to a male head 6. The number of female sleeves 5 and male heads 6 is the same as the number of pushers 3. The male head 6 is inserted into the female sleeve 5. The female sleeve 5 is provided with a positioning component for fixing the male head 6. The positioning component includes a movable ring 7 that is slidably sleeved on the female sleeve 5, and a gap is formed between the movable ring 7 and the female sleeve 5. A spring 71 is sleeved on the female sleeve 5. The spring 71 is located in the gap, and the two ends of the spring 71 are respectively connected to the female sleeve 5 and the movable ring. The raised surface of 7 is fixedly connected. The female sleeve 5 has multiple through holes 72 that are circumferentially through it. A positioning ball 73 is slidably installed in the through hole 72. The male head 6 has a slot 74. When the male head 6 is inserted into the female sleeve 5, the positioning ball 73 is engaged in the slot 74. Here, the diameter of the positioning ball 73 is larger than the diameter of the through hole 72 at the inner wall of the female sleeve 5, and the diameter of the positioning ball 73 is smaller than the diameter of the through hole 72 at the outer wall of the female sleeve 5, so that the positioning ball 73 can slide in the through hole 72 without falling off.

[0023] Specifically, in use, firstly, the moving ring 7 is pushed to slide along the female sleeve 5, compressing the spring 71 and releasing the squeezing limit on the positioning ball 73. Then, the male head 6 is inserted into the female sleeve 5, and the moving ring 7 is released. Under the elastic force of the spring 71, the moving ring 7 quickly returns to its original position and squeezes the positioning ball 73 into the slot 74 to fix the male head 6. This allows workers to quickly and flexibly disassemble and assemble the pusher 3, and facilitates the combination and matching of pushers 3 of different sizes and specifications on the multi-station of the turntable 2, thereby improving the efficiency of the chip welding strength testing process.

[0024] In this invention, during use, the servo motor 41 can be started according to the size and model of the chip, driving the worm gear 43, worm wheel 42, and rotating rod 4 to rotate, and driving the turntable 2 to rotate 60° each time. This allows for sequential switching of multiple pusher blades 3 of different sizes and specifications, achieving rapid matching of the pusher blades 3. This can quickly meet the testing needs of chips of different models and sizes, thereby helping to improve testing efficiency.

[0025] In addition, during use, by pushing the moving ring 7 to slide along the female sleeve 5 and compressing the spring 71, the pressure limit on the positioning ball 73 is released. Then, the male head 6 is inserted into the female sleeve 5, and the moving ring 7 is released. Under the elastic force of the spring 71, the moving ring 7 quickly returns to its original position and presses the positioning ball 73 into the slot 74 to complete the fixation of the male head 6. This allows workers to quickly and flexibly disassemble and assemble the pusher 3, thereby facilitating the combination and matching of pushers 3 of different sizes and specifications on the multi-station of the turntable 2, thereby improving the efficiency of the chip welding strength testing process.

[0026] Components not described in detail in this article are existing technologies.
