Description

Technical Field

[0001] This utility model relates to the field of chip packaging technology manufacturing, and in particular to a universal BGA ball-planting fixture. Background Technology

[0002] Currently, most electronic components such as computer motherboard chips and CPUs use Ball Grid Array (BGA). BGA is an advanced integrated circuit packaging technology that replaces the soldering leads of traditional chips with solder balls, resulting in a higher pin density than traditional chips. This allows for smaller spacing between the pins, making it suitable for high-density circuit designs. When soldering chips using BGA, they need to be placed in a specific ball-mounting fixture.

[0003] Existing ball-mounting fixtures have limitations, making it impossible to adjust the height and horizontal angle of the chip relative to the steel ball-mounting mold. When it is necessary to adjust the angle or height of the chip on the ball-mounting fixture, the chip position can only be manually adjusted. However, chip ball-mounting requirements vary widely, and the pin pitch of BGA ball grid arrays is small, making manual operation insufficient for precise chip adjustment. Utility Model Content

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: 1. By setting an angle adjustment mechanism and a height adjustment mechanism between the base and the steel sheet fixing mechanism, the angle adjustment mechanism cooperates with the first adjustment component through the adjustment plate to realize the angle adjustment of the tray, and the height adjustment mechanism cooperates with the second adjustment component through the height movement component to realize the height adjustment of the tray. This adjusts the angle and height of the tray (used to fix the chip waiting for ball placement material) relative to the steel sheet fixing mechanism (used to fix the ball placement steel sheet), so that the steel sheet can place balls on the chip at the target angle and height to meet multiple ball placement needs. Furthermore, the angle adjustment mechanism and the height adjustment mechanism can stably adjust the angle and height of the tray and ensure that the tray maintains positional stability after adjustment, avoiding positional instability phenomena such as manual manipulation.

[0016] 2. By using a micrometer adjustment head, the angle, height, X-axis, and Y-axis adjustment amounts can be quantified, enabling more precise adjustment of the tray angle and height, as well as the X-axis and Y-axis positions of the steel sheet fixing mechanism. This allows for the installation of chips with a pitch of 0.4mm to 1.5mm and solder balls of 0.2mm to 0.76mm, overcoming the bottleneck of difficulty in ball placement for small-pitch chips.

[0017] 3.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0020] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. Conversely, when an element is said to be "directly on" another element, there is no intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] See Figure 1 and Figure 2 The present invention provides a universal BGA ball-planting fixture, comprising a base 1, a support plate 2, an angle adjustment mechanism 3, a height adjustment mechanism 4, and a steel plate fixing mechanism 5. The steel plate fixing mechanism 5 is disposed on the base 1, and the angle adjustment mechanism 3, the height adjustment mechanism 4, and the support plate 2 are sequentially disposed between the base 1 and the steel plate fixing mechanism 5. The angle adjustment mechanism 3 includes an adjustment plate 31, a first adjustment component 32, and at least one connecting rod 33. The adjustment plate 31 is rotatably connected to the base 1. The first adjustment component 32 is disposed at the side end of the base 1, and the moving end of the first adjustment component 32 is connected to the side of the adjustment plate 31. One end of the connecting rod 33 is fixedly connected to the adjustment plate 31, and the other end of the connecting rod 33 is movably connected to the support plate 2. The height adjustment mechanism 4 includes a height movement component 41 and a second adjustment component 42. One end of the height movement component 41 is fixedly connected to the adjustment plate 31, and the other end of the height movement component 41 is fixedly connected to the support plate 2. The second adjustment component 42 is located at the side of the base 1, and the movement end of the second adjustment component 42 is connected to the side of the height movement component 41.

[0023] In this embodiment, the tray 2 is used to fix the chip waiting for the ball-planting material, and the steel sheet fixing mechanism 5 is used to fix the ball-planting steel sheet. The ball-planting steel sheet is provided with multiple micro-holes for ball planting so that the solder balls can be planted onto the chip through the micro-holes.

[0024] Angle adjustment mechanism 3 is used to adjust the angle of the pallet 2 relative to the steel sheet fixing mechanism 5. The adjustment plate 31 is rotatably connected to the base 1. One end of the connecting rod 33 is fixedly connected to the adjustment plate 31, and the other end is movably connected to the pallet 2. When the adjustment plate 31 rotates horizontally, the connecting rod 33 drives the pallet 2 to rotate horizontally, thereby achieving angle adjustment of the pallet 2. The connecting rod 33 ensures the accuracy of the pallet 2 angle adjustment and effectively prevents positional deviation of the height movement component 41 during movement, which would affect the accuracy of the pallet 2 angle adjustment. The moving end of the first adjustment component 32 is connected to the side of the adjustment plate 31. When the first adjustment component 32 is working, its moving end pushes or pulls the adjustment plate 31, causing the adjustment plate 31 to rotate horizontally on the base 1. Optionally, the moving end of the first adjusting component 32 is fixedly connected to the side of the adjusting plate 31. When the moving end of the first adjusting component 32 moves toward the adjusting plate 31, its moving end pushes the adjusting plate 31 to rotate in the first direction (e.g., clockwise); when the moving end of the first adjusting component 32 moves away from the adjusting plate 31, its moving end pulls the adjusting plate 31 to rotate in the second direction (e.g., counterclockwise).

[0025] The height adjustment mechanism 4 is used to adjust the height of the pallet 2, i.e., the distance relative to the steel plate fixing mechanism 5. One end of the height movement component 41 is fixedly connected to the adjusting plate 31, and the other end is fixedly connected to the pallet 2. The other end of the connecting rod 33 passes through the pallet 2 and is movably connected to it, so that when the height movement component 41 moves up and down, it drives the pallet 2 to move up and down, thereby adjusting the height of the pallet 2. The moving end of the second adjustment component 42 is connected to the side of the height movement component 41, so that when the second adjustment component 42 is working, its moving end pushes or pulls the height movement component 41, causing the height movement component 41 to move upward or downward, thus causing the pallet 2 to move upward or downward. Optionally, the moving end of the second adjustment component 42 is fixedly connected to the side of the height movement component 41. The height movement component 41 achieves upward movement by offset movement of two inclined moving parts, where one moving part applies force to the side, and the other moving part moves upward by offset movement relative to the first moving part.

[0026] For example, the chip is fixed on the tray 2, and the ball-mounting steel sheet is fixed on the steel sheet fixing mechanism 5. The first adjusting component 32 drives the adjusting plate 31 to rotate, so as to drive the chip on the tray 2 to rotate horizontally to the target angle. The second adjusting component 42 drives the height movement component 41 to move, so as to drive the chip on the tray 2 to move up or down to the target height, thus completing the adjustment of the chip's angle and height. Then, solder paste is applied to the ball-mounting steel sheet, so that the solder paste passes through the micro-holes on the ball-mounting steel sheet to be placed onto the chip. Finally, after heating and other subsequent processes, the chip BGA ball-mounting is completed.

[0027] In some embodiments, such as Figure 3As shown, a rotating assembly 11 is provided between the base 1 and the adjusting plate 31. The rotating assembly 11 includes a rotating bearing 111 and a rotating shaft 112. The rotating bearing 111 and the rotating shaft 112 are rotatably connected. The rotating bearing 111 is fixedly connected to the base 1, and the rotating shaft 112 is fixedly connected to the adjusting plate 31.

[0028] In this embodiment, the rotary bearing 111 can be embedded in the base 1 or mounted on the surface of the base 1; the rotary shaft 112 is fixedly connected to the bottom surface of the adjusting plate. This embodiment improves the smoothness of rotation of the adjusting plate 31 by setting the rotary assembly 11 to be fixedly connected to the adjusting plate 31.

[0029] In some embodiments, such as Figure 4 As shown, the first adjustment assembly 32 includes a first rotary adjustment member 321 and a first spring limiting member 322. The first rotary adjustment member 321 includes a first micrometer adjustment head 3211 and a first adjustment rod 3212 connected to the first micrometer adjustment head 3211. The first rotary adjustment member 321 and the first spring limiting member 322 are respectively disposed on two symmetrical sides of the base 1, and one end of the first adjustment rod 3212 is connected to one side of the adjustment plate 31, and one end of the first spring limiting member 322 is connected to the other side of the adjustment plate 31.

[0030] In this embodiment, the first micrometer adjusting head 3211 is equipped with a micrometer. When the first micrometer adjusting head 3211 is rotated clockwise or counterclockwise according to the micrometer scale, the first adjusting rod 3212 moves forward or backward a distance corresponding to the scale, thereby causing the adjusting plate 31 to rotate by a preset angle. The first spring limiting member 322 plays a limiting and buffering role, allowing the adjusting plate 31 to rotate within a certain range and preventing collisions.

[0031] Optionally, the relationship between the rotation angle of the adjusting plate 31 and the movement distance of the first adjusting rod 3212 can be calculated according to the installation position and movement distance of the first adjusting rod 3212, so that the micrometer scale can be represented by the rotation angle of the adjusting plate 31, so as to intuitively adjust the rotation angle of the tray 2.

[0032] In some embodiments, such as Figure 5 As shown, the height movement component 41 includes a first triangular slider 411 and a second triangular slider 412. The first triangular slider 411 is movably connected to the adjustment plate 31, and the second triangular slider 412 is fixedly connected to the support plate 2. The inclined surface of the first triangular slider 411 abuts against the inclined surface of the second triangular slider 412.

[0033] In this embodiment, the first triangular slider 411 and the second triangular slider 412 move in a staggered motion along their inclined surfaces, enabling the first triangular slider 411 to be pushed horizontally so that the second triangular slider 412 moves vertically, thereby realizing the height adjustment function of the height movement component 41. Optionally, a slider is provided between the inclined surfaces of the first triangular slider 411 and the second triangular slider 412. The first triangular slider 411 is slidably connected to one side of the slider, and the other side of the slider is slidably connected to the second triangular slider 412. This improves the sliding stability of the third slider 411 and the second triangular slider 412, and allows for the replacement of sliders of different thicknesses to meet different height adjustment needs.

[0034] In some embodiments, such as Figure 5 As shown, the second adjustment component 42 includes a second rotary adjustment member 421, which includes a second micrometer adjustment head 4211 and a second adjustment rod 4212 connected to the second micrometer adjustment head 4211. The second rotary adjustment member 421 is located at the side of the base 1, and one end of the second adjustment rod 4212 is fixedly connected to the vertical surface of the first triangular slider 411.

[0035] In this embodiment, the second micrometer adjusting head 4211 is equipped with a micrometer. When the second micrometer adjusting head 4211 is rotated clockwise or counterclockwise according to the micrometer scale, the second adjusting rod 4212 moves forward or backward a distance corresponding to the scale, thereby causing the tray 2 to move up or down a preset height. Optionally, the correspondence between the movement distance of the second triangular slider 412 and the movement distance of the second adjusting rod can be calculated according to the inclination of the inclined surfaces of the first triangular slider 411 and the second triangular slider 412, so that the micrometer scale is represented by the movement distance of the second triangular slider 412, so as to intuitively adjust the height of the tray 2.

[0036] In some embodiments, such as Figure 6 As shown, the steel sheet fixing mechanism 5 includes a support block 51, a first fixing plate 52 and a second fixing plate 53. One end of the support block 51 is connected to the base 1, and the other end of the support block 51 is provided with a connecting post 511. The connecting post 511 passes through the first fixing plate 52 and the second fixing plate 53 in sequence. The first fixing plate 52 and the second fixing plate 53 are detachably connected.

[0037] In this embodiment, the ball-planting steel sheet is installed between the first fixing plate 52 and the second fixing plate 53. The first fixing plate 52 and the second fixing plate 53 are detachably fixedly connected, for example, by bolts or snap-fit ​​connections. A connecting post 511 is provided on the support block 51 to position the ball-planting steel sheet on the steel sheet fixing mechanism 5 and to improve installation stability.

[0038] In some embodiments, the first fixing plate 52 and the second fixing plate 53 are both hollow structures, and the angle adjustment mechanism 3, the height adjustment mechanism 4 and the support plate 5 are disposed within the hollow structure; there are at least two support blocks 51, which are respectively disposed at both ends of the base 1.

[0039] In this embodiment, a hollow first fixing plate 52 and a second fixing plate 53 are used to fix all four sides of the ball-planting steel sheet, thereby improving the fixing effect. At least two support blocks 51 are used to improve the positioning accuracy and support of the ball-planting steel sheet, thus ensuring the ball-planting precision.

[0040] In some embodiments, such as Figure 6 and Figure 7 As shown, the support block 51 is connected to the base 1 via an X-axis adjustment mechanism 6 and a Y-axis adjustment mechanism 7. The Y-axis adjustment mechanism 7 includes a Y-axis moving component 71 and a third adjustment component 72. The bottom surface of the Y-axis moving component 71 is slidably connected to the base 1. The third adjustment component 72 is located at the edge of the base 1, and the moving end of the third adjustment component 72 is connected to the side of the Y-axis moving component 71. The X-axis adjustment mechanism 6 includes an X-axis moving component 61 and a fourth adjustment component 62. The bottom surface of the X-axis moving component 61 is slidably connected to the top surface of the Y-axis moving component 71. The fourth adjustment component 62 is located at the side of the base 1, and the moving end of the fourth adjustment component 62 is connected to the side of the X-axis moving component 61. The top surface of the X-axis moving component 61 is fixedly connected to one end of the support block 51. The movement direction of the Y-axis moving component 71 is perpendicular to the movement direction of the X-axis moving component 61.

[0041] In this embodiment, the X-axis adjustment mechanism 6 and the Y-axis adjustment mechanism 7 are used to adjust the position of the steel sheet fixing mechanism 5 in the X-axis and Y-axis directions, respectively, that is, to adjust the X-axis and Y-axis positions of the ball-mounting steel sheet relative to the chip on the support plate 2, thereby improving the positioning accuracy between the chip and the ball-mounting steel sheet. When the moving end of the third adjustment component 72 is pushed out or pulled back, it drives the Y-axis moving component 71 to move forward or backward; when the moving end of the fourth adjustment component 62 is pushed out or pulled back, it drives the X-axis moving component 61 to move forward or backward.

[0042] In some embodiments, such as Figure 8As shown, the bottom surface of the Y-axis moving component 71 is slidably connected to the base 1 via a slide rail; the third adjustment component 72 includes a third rotary adjustment component 721 and a second spring limiting component 722. The third rotary adjustment component 721 includes a third micrometer adjusting head 7211 and a third adjusting rod 7212 connected to the third micrometer adjusting head 7211.

[0043] In this embodiment, the third micrometer adjusting head 7211 is equipped with a micrometer. When the third micrometer adjusting head 7211 is rotated clockwise or counterclockwise according to the micrometer scale, the third adjusting rod 7212 moves forward or backward a corresponding scale distance, thereby causing the Y-axis moving component 71 to move forward or backward a corresponding scale distance. The second spring limiting component 722 plays a limiting and buffering role, allowing the Y-axis moving component 71 to move within a certain range and preventing collisions.
