Abstract
Description
Technical Field
[0001] This utility model relates to the field of electroplating, specifically to a hanging fixture. Background Technology
[0002] Integrated circuits are used in all current electronic devices, and these circuits require a substrate for placement. During the production process, the substrate needs to be electroplated, usually using a rack. The substrate is placed on the rack, and then the rack is placed into the electroplating equipment. Using a rack makes it easy to immerse the substrate in the electroplating solution, allowing the electroplating operation to be performed on the substrate.
[0003] The structure of a commonly used mounting bracket mainly includes a frame, on which conductive hooks for connecting to electroplating equipment are set. Conductive frames are set on the conductive hooks. Typically, a carrier plate is placed on the conductive frame to form a cathode, which then forms an electric field with the anode on the electroplating equipment. The current in the electric field passes through the carrier plate, ionizing the electroplating solution and attaching the metal ions in the electroplating solution to the carrier plate, thereby completing the electroplating process.
[0004] However, because the carrier plate is currently bonded to the conductive frame, the metal ions from electroplating adhere to the surface of the carrier plate, causing the carrier plate to stick to the conductive frame. Furthermore, placing the carrier plate directly into the conductive frame results in a buildup of metal at the contact point after prolonged use, preventing proper adhesion between the carrier plate and the conductive parts. Consequently, the thickness of the metal layer deposited on the carrier plate during subsequent electroplating operations is uneven. Utility Model Content

[0033] To further understand the utility model's content, features, and effects, the following embodiments are provided, along with detailed descriptions in conjunction with the accompanying drawings:
[0034] Figure 1 This is a three-dimensional structural diagram of the hanger in this embodiment, such as... Figure 1 As shown, this embodiment discloses a hanger, which includes a hanging frame 1 and at least two placement frames 2, wherein the hanging frame 1 is used to hang the hanger in the electroplating equipment, and the placement frames are used to place the integrated circuit substrate to be electroplated.
[0035] Figure 2 This is a three-dimensional structural diagram of the hanging frame in this embodiment, such as... Figure 1 and Figure 2As shown, the hanging frame 1 includes at least three hooks 11 and a frame 12. The frame 12 is divided by at least two parallel middle frames 121. The at least three hooks 11 are located on the same side of the frame 12, with two hooks located at both ends of the frame 12. A hook 11 is provided between two adjacent middle frames 121. The hooks 11 can hang the fixture into the electroplating equipment and allow the fixture to be immersed in the electroplating solution. The middle frames 121 are designed to be hollow to prevent obstruction of the integrated circuit substrate, thereby allowing a current loop to be formed between the integrated circuit substrate and the anode, thus enabling copper plating on the integrated circuit substrate. In this embodiment, three hooks 11 are provided.
[0036] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, Figure 3 This is an enlarged view of one of the first grid frames 211 and one of the second grid frames 221 stacked together. Each placement frame 2 includes a conductive frame 21 and a clamping frame 22. Multiple first grid frames 211 are spaced apart on the conductive frame 21, and multiple conductive contacts 2111 are arranged around the edge of each first grid frame 211. Multiple second grid frames 221 are spaced apart on the clamping frame 22, and at least two clamps 2211 are arranged around the edge of each second grid frame 221. Each middle frame 121 has one conductive frame 21 mounted on it, and each conductive frame 21 has one clamping frame 22 mounted on it. Each first grid frame 211 corresponds to one second grid frame 221, and the multiple conductive contacts 2111 extend into the second grid frame 221. Preferably, the multiple first grid frames 211 are arranged in an array, and similarly, the multiple second grid frames 221 are also arranged in an array.
[0037] In operation, an integrated circuit carrier board is placed on the clamp frame 22 and fixed by the clamp 2211. When working, the conductive frame 21 is connected to the cathode of the electroplating equipment, so that the conductive contacts 2111 contact each integrated circuit carrier board, making each integrated circuit carrier board a cathode. The electroplating equipment is equipped with an anode, and current flows from the anode through the cathode, thereby electrolyzing the electroplating solution, causing the metal ions in the electroplating solution to adhere to the integrated circuit carrier board.
[0038] Specifically, such as Figure 1 and Figure 3As shown, the area of each second grid frame 221 is larger than the area of each first grid frame 211. A clamp 2211 is positioned on the second grid frame 221 around the edge of the conductive contact 2111. The larger area of the second grid frame 221 allows the integrated circuit substrate to be placed on the conductive contact 2111 without obstructing it, enabling one side of the integrated circuit substrate to contact the conductive contact 2111. Once one side of the integrated circuit substrate contacts the conductive contact 2111, the clamp 2211, positioned around the edge of the conductive contact 2111, precisely secures the integrated circuit substrate, preventing it from moving and fixing it between the conductive contact 2111 and the clamp 2211.
[0039] Specifically, such as Figure 1 As shown, each hook 11 is also provided with a first fastener 111, and each conductive frame 21 is provided with a connection hole 212 corresponding to the fastener 111. The first fastener 111 passes through the connection hole 212 to connect the conductive frame 21 to the hanging frame 1, thereby fixing the conductive frame 21 to the hanging frame 1 and preventing the conductive frame 21 from falling off the hanging frame 1 during the electroplating process.
[0040] Preferably, such as Figure 4 As shown, a second fastener 121 is also provided at the bottom of the middle frame 12, and a limiting groove 213 is also provided at the bottom of the conductive frame 21. The second fastener 121 is engaged with the limiting groove 213. In order to prevent the conductive frame 21 from being unbalanced at one end, a limiting groove 213 is provided at the bottom of the conductive frame 21, and a second fastener is also provided at the bottom of the middle frame 12 to engage with the limiting groove 213 to better fix the conductive frame 21.
[0041] Specifically, such as Figure 5As shown, the clamp 2211 includes at least one fixing clamp 22111, at least one elastic element 22112, and a fixing buckle 22113. At least one notch 222 is provided on the second grid frame 221 corresponding to each clamp 22. A fixing clamp 22111 is movably disposed within each notch 222. The fixing buckle 22113 is fixed to the second grid frame 221. The elastic element 22112 is located within the fixing buckle, with one end connected to the fixing clamp and the other end abutting against the fixing buckle 22113. In this embodiment... When the clamp 2211 is positioned at the top and bottom of the second grid frame 221, since there is no second grid frame 221 above and below the clamp 2211, only a notch 222 needs to be opened at the top and bottom. The fixing clamp 22111 is movably connected to the notch 222, thereby allowing for the telescopic fixing of integrated circuit carrier boards of different sizes. The elastic element 22112 facilitates the telescopic movement of the fixing clamp 22111. The fixing buckle 22113 abuts against the other end of the elastic element 22112, fixing the elastic element 22112 so that the fixing clamp 22111 can spring back after telescopic movement. The fixing buckle 22113 also prevents the elastic element 22112 and the fixing clamp 22111 from falling off.
[0042] Specifically, such as Figure 6 and Figure 7 As shown, the clamp 2211 includes at least an even number of fixed clamps 22111, at least one elastic element 22112, and a fixed buckle 22113. An even number of notches 222 are provided on the second grid frame 221 corresponding to the position of each clamp 2211. The notches 222 are located on both sides of the frame of the second grid frame 221 and are opposite to each other. A fixed clamp 22111 is movably disposed in each notch 222. An elastic element 22112 is provided between two opposite fixed clamps 22111. One end of the elastic element 22112 is connected to one fixed clamp 22111, and the other end is connected to the other fixed clamp 22111. The fixed buckle 22113 is fixed on the second grid frame 221, and the elastic element 22112 is located inside the fixed buckle 22113. When the clamp 2211 is not installed at the top or bottom of the clamp frame 22, two fixing clamps 22111 are provided because the clamp 2211 has a second grid frame 221 above and below it. At the same time, because two fixing clamps 22111 are provided, the elastic element 22112 is placed between the two fixing clamps 22111.
[0043] Preferably, such as Figure 1 As shown, the first grid frames 211 are arranged in an array, and the second grid frames 221 are also arranged in an array. In this way, the hanger can hold a larger number of integrated circuit carrier boards, and the area of the hanging frame 1 and the placement frame 2 can be reduced.
[0044] Preferably, such as Figure 1As shown, a first washer 113 is also provided on the hook 11. The first washer 113 is disposed on the first fastener 111, and the first washer 112 abuts against one side of the conductive frame 21. Specifically, to prevent the first fastener 111 from being unstable when fixing the conductive frame 21, the first washer 112 is provided at the bottom of the first fastener 111, making the conductive frame 21 more securely fixed.
[0045] Preferably, such as Figure 4 As shown, a second gasket 122 and a second fastener 123 are also provided at the bottom of the middle frame 12. The second gasket 122 is disposed on the second fastener 123 and abuts against the limiting groove 213. The function of the second gasket 122 is the same as that of the first gasket 112, and will not be described again here.
[0046] Preferably, such as Figure 8 As shown, an insulating sleeve 23 is provided between the conductive frame 21 and the clamping frame 22, and a connector 221131 passes through the insulating sleeve 23 and is connected to the conductive frame 21. The conductive frame 21 and the clamping frame 22 are metal frames, and the connector 221131 is also a metal component. Therefore, during the electroplating operation, to prevent short circuits in the integrated circuit substrate, which could lead to uneven metal layer thickness on the integrated circuit substrate, the insulating sleeve 23 is used between the conductive frame 21 and the clamping frame 22 to avoid short circuits between the conductive frame 21 and the clamping frame 22 affecting the electroplating of the substrate.
[0047] In summary, the mounting fixture of this utility model, by providing a conductive frame 21 and a clamping frame 22, with conductive contacts 2111 on the conductive frame 21, eliminates the need for the integrated circuit carrier to be directly and completely attached to the conductive frame 21, preventing the carrier from sticking to the conductive frame 21. Simultaneously, the conductive contacts 2111 on the conductive frame 21 and the clamping frame 22 are equipped with clamps 2211, which fix the integrated circuit carrier to itself. During electroplating, the integrated circuit carrier will not shift, and excessive metal layer accumulation on the conductive contacts 2111 is also prevented.
[0048] The above are merely embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
