Description

Technical Field

[0001] This utility model belongs to the field of circuit board processing technology, specifically relating to a miniaturized pin packaging structure for HDI boards. Background Technology

[0002] HDI boards are a type of circuit board, belonging to the category of high-density interconnect circuit boards. They feature higher line density and smaller vias, making them suitable for high-performance, highly integrated electronic products. Compared to traditional printed circuit boards, HDI boards can provide more connection points in a smaller space, thus supporting more complex circuit designs.

[0003] Pin-mount packaging for HDI boards is a high-precision and highly complex technology. Before pin-mount packaging, the HDI board usually needs to be fixed in the packaging base to ensure that the board does not shift during the entire packaging process. Existing packaging fixing structures require custom-made fixtures based on the specific size of the HDI board and packaging requirements, which is costly. At the same time, when packaging pins, they need to be precisely placed in the predetermined position. HDI boards have a high density, and pins need to be precisely aligned with the connection points of the circuit. Existing packaging structures cannot be positioned and packaged according to different HDI boards, lacking flexibility and only able to handle some specific boards, which limits the versatility of production packaging. Utility Model Content

[0004] The purpose of this invention is to provide a miniaturized pin packaging structure for HDI boards, which can assist in the positioning of different circuit boards, avoid circuit board displacement, and ensure perfect alignment during the packaging process.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A miniaturized pin packaging structure for an HDI board includes a fixed base and a positioning groove. The positioning groove is formed on the top of the fixed base, and structural grooves are formed on both sides of the inner wall of the positioning groove. A positioning mechanism is provided inside the structural groove. The positioning mechanism includes a compression spring, a positioning element, a push rod, and a pull rod. One end of the compression spring is fixedly connected to the inner wall of the structural groove, and the positioning element is fixedly connected to the other end of the compression spring. The positioning element is respectively disposed inside the structural groove. One end of the push rod is fixedly connected to the outer side of the positioning element, and the other end of the push rod extends through to the outer side of the fixed base. The push rod is movably disposed inside the compression spring, and the pull rod is fixedly installed on the outer end of the push rod.

[0007] Preferably, the inner side of the positioning member is set as an inclined surface with an angle of forty degrees, and a protective layer is fixedly connected to the bottom of the positioning member, the protective layer being made of rubber.

[0008] Preferably, the positioning member is fixedly connected to the front and rear sides with sliders, and the inner wall of the structural groove is provided with grooves on the front and rear sides for use with the sliders.

[0009] Preferably, the top of the fixed base has two vertical grooves, the top of the inner wall of the vertical groove is fixedly connected to a baffle, the inside of the vertical groove is movably connected to a circular plate, the top of the circular plate is fixedly connected to a screw, the screw extends to the top of the baffle, the top of the fixed base is provided with an auxiliary positioning plate, both ends of the auxiliary positioning plate are sleeved on the top of the screw, the surface of the screw is threaded with a fastening nut, the fastening nut is located on the top of the auxiliary positioning plate, and the top of the auxiliary positioning plate is provided with an auxiliary insertion hole.

[0010] Preferably, the diameter of the top of the auxiliary socket is larger than the diameter of the bottom, and there are several auxiliary sockets that are equidistantly distributed on the top of the auxiliary positioning plate.

[0011] Preferably, a support frame is installed on the top of the positioning groove, and the support frame is made of an elastic material.

[0012] Preferably, the compression springs are of several types and are evenly distributed on the inner wall of the structural groove.

[0013] The technical effects achieved by this utility model are as follows:

[0014] In this invention, during the processing and packaging of the circuit board, the circuit board can be directly placed between two positioning components. Pressing the circuit board down, with the cooperation of the inclined surfaces inside the positioning components, compresses the positioning components on both sides, causing them to move into the structural groove and compressing the compression spring. After the circuit board is compressed against the positioning components, it moves to the bottom of the positioning components and is positioned in the positioning groove. Then, under the elastic force of the compression spring, it pushes the positioning components to move inward simultaneously. With the blocking and limiting effect of the two positioning components, the circuit board can be automatically positioned and limited within the fixed base. Thus, with the cooperation of the positioning mechanism, different circuit boards can be positioned within the fixed base, ensuring that the circuit board will not shift or move during the entire packaging process, thus ensuring the stability of the packaging process.

[0015] In this invention, after the circuit board is fixed and positioned within the fixed base, the two ends of the auxiliary positioning plate can be fitted onto the surfaces of the two screws. Then, the position on the circuit board where the pins to be packaged is aligned with the auxiliary insertion holes on the auxiliary positioning plate. When aligning the two, the screws on both sides and the circular plate can slide inside the vertical groove, thereby driving the auxiliary positioning plate to move horizontally to adjust its position. After adjusting and aligning the auxiliary positioning holes with the positions of the packaged pins on the circuit board, the fastening nut can be turned downwards. Through the cooperation of the fastening nut and the screws, the auxiliary positioning plate can be fixed. Thus, when packaging the pins, with the cooperation of the auxiliary holes, the pins can be accurately packaged on the circuit board, ensuring that the pins are packaged in the correct positions, thereby improving the accuracy and quality of the packaging.

Detailed Implementation

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figures 1-4As shown, a miniaturized pin packaging structure for an HDI board includes a fixing base 1 and a positioning groove 101. The positioning groove 101 is formed on the top of the fixing base 1. Structural grooves 2 are formed on both sides of the inner wall of the positioning groove 101. A positioning mechanism is provided inside the structural groove 2. The positioning mechanism includes a compression spring 201, a positioning element 202, a push rod 203, and a pull rod 204. One end of the compression spring 201 is fixedly connected to the inner wall of the structural groove 2. The positioning element 202 is fixedly connected to the other end of the compression spring 201 and is respectively disposed inside the structural groove 2. One end of the push rod 203 is fixedly connected to the outer side of the positioning element 202. The other end of 3 extends to the outside of the fixed base 1. The push rod 203 is movably disposed inside the compression spring 201, and the pull rod 204 is fixedly installed on the outer end of the push rod 203. After the positioning groove 101 in the fixed base 1 is processed, the push rod 203 can be pulled outward by holding the pull rod 204. The push rod 203 will drive the positioning member 202 to move into the interior of the structural groove 2 and squeeze the compression spring 201, so that the positioning member 202 can be released from the limit of the circuit board. Then the circuit board can be removed from the positioning groove 101. This not only allows for quick positioning of the circuit board, but also allows for quick separation of the circuit board from the fixed base 1.

[0024] like Figures 1-3 As shown, the inner side of the positioning member 202 is set as an inclined surface with an angle of 40 degrees. A protective layer 3 is fixedly connected to the bottom of the positioning member 202. The protective layer 3 is made of rubber. The inclined surface on the inner side of the positioning member 202 can reduce the frictional resistance between the circuit board and the positioning member 202, so that the circuit board can smoothly squeeze the positioning member 202 and move to the bottom of the positioning member 202 and be fixed. The protective layer 3 at the bottom of the positioning member 202 can effectively reduce the direct contact between the positioning member 202 and the circuit board, thereby reducing the risk of friction and wear. The softness of the rubber material plays a buffering role, avoiding scratches or damage to the surface of the circuit board caused by metal or hard materials.

[0025] like Figure 2 and Figure 3 As shown, sliders 401 are fixedly connected to the front and rear sides of the positioning member 202. The front and rear sides of the inner wall of the structural groove 2 are provided with sliding grooves 402 that cooperate with the sliders 401. When the positioning member 202 is squeezed, the positioning member 202 will drive the sliders 401 to slide along the inside of the sliding grooves 402. Under the guidance of the cooperation between the sliding grooves 402 and the sliders 401, the positioning member 202 can be restricted to move smoothly, preventing the positioning member 202 from shifting or tilting during the movement, thereby ensuring the accurate positioning of the positioning member 202 and avoiding incorrect positioning or errors.

[0026] like Figure 1 and Figure 4As shown, the top of the fixed base 1 has two vertical slots 501. A stop bar 502 is fixedly connected to the top of the inner wall of each vertical slot 501. A circular plate 503 is movably connected inside the vertical slots 501. A screw 504 is fixedly connected to the top of the circular plate 503, extending through to the top of the stop bar 502. An auxiliary positioning plate 505 is provided on the top of the fixed base 1. Both ends of the auxiliary positioning plate 505 are fitted onto the top of the screw 504. A fastening nut 506 is threaded onto the surface of the screw 504, located on top of the auxiliary positioning plate 505. An auxiliary insertion hole 507 is provided at the top. The stop bar 502 can block and limit the round block inside the vertical groove 501. The auxiliary positioning plate 505 can be fixed by the cooperation of the fastening nut 506 and the screw 504. At the same time, with the cooperation of the vertical groove 501 and the round plate 503, stepless adjustment can be achieved, which can facilitate precise adjustment of the position of the auxiliary positioning plate 505. Thus, when encapsulating the pin, with the cooperation of the auxiliary hole, the pin can be accurately encapsulated on the circuit board, ensuring that the pin is encapsulated in the correct position, thereby improving the accuracy and quality of encapsulation.

[0027] like Figure 1 and Figure 4 As shown, the top diameter of the auxiliary socket 507 is larger than the bottom diameter. There are several auxiliary sockets 507, which are evenly distributed on the top of the auxiliary positioning plate 505. Since the top diameter of the auxiliary socket 507 is larger than the bottom diameter, the pin can be more stably aligned and positioned in the correct position when inserted. The larger top diameter helps guide the pin into the hole, thereby reducing the deviation during the insertion process. This helps to improve the pin packaging accuracy and ensure that each pin is correctly placed in the predetermined position.

[0028] like Figure 1 and Figure 2 As shown, a support frame 6 is installed on the top of the positioning groove 101. The support frame 6 is made of elastic material and has a certain deformation capacity, which can adapt to the size of different circuit boards. Especially in mass production, the size of the circuit boards may have slight differences. The elastic material can effectively adjust to adapt to these differences and ensure that the circuit board is well supported. At the same time, the elastic support frame 6 can firmly fix the circuit board in the designated position during packaging to prevent the circuit board from shifting during packaging or use.

[0029] like Figure 2 As shown, there are several compression springs 201, which are evenly distributed on the inner wall of the structural groove 2. The multiple compression springs 201 can evenly push the positioning member 202 to position the circuit board, effectively preventing any side of the circuit board from being subjected to excessive or insufficient pressure, thereby ensuring that the circuit board is accurately and stably positioned during the packaging or assembly process.

[0030] The working principle of this utility model is as follows: When processing and packaging a circuit board, the circuit board can be directly placed between two positioning members 202. Then, pressing the circuit board down, with the cooperation of the inclined surface on the inner side of the positioning member 202, can squeeze the positioning members 202 on both sides into the interior of the structural groove 2, and squeeze the compression spring 201. After the circuit board squeezes the positioning member 202, the circuit board will move to the bottom of the positioning member 202 and be located on the positioning groove 101. Then, under the elastic force of the compression spring 201, it will push the positioning member 202 to move inward at the same time. Under the blocking and limiting of the two positioning members 202, the circuit board can be automatically positioned and limited in the fixed base 1. Thus, with the cooperation of the positioning mechanism, different circuit boards can be positioned in the fixed base 1, thereby ensuring that the circuit board will not shift or move during the entire packaging process, ensuring the stability of the packaging process.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
