Description

Technical Field

[0001] The utility model belongs to the technical field of circuit boards, and in particular relates to a collaboratively produced PCB circuit board. Background Art

[0002] Collaborative production of PCB circuit boards means that multiple links and departments participate together to complete the entire process from design, manufacturing to testing, and finally produce circuit boards that meet the requirements. This production method emphasizes close cooperation and information sharing between departments to ensure the quality and performance of the circuit boards.

[0003] Existing PCB circuit boards need to go through multiple steps during collaborative production. During transportation, the surface of the circuit board may be worn, causing damage to the circuit and the circuit board. In addition, the circuit board is generally fixed directly inside the equipment with bolts. When maintenance is required, the bolts need to be removed. However, the threaded holes on the machine may have threads, making it difficult to remove the bolts more conveniently. It may even cause damage to the circuit board during removal. Therefore, we propose a collaboratively produced PCB circuit board. Utility Model Content

[0004] The purpose of the present invention is to provide a collaboratively produced PCB circuit board to solve the technical problem that the existing PCB circuit boards need to go through multiple steps during collaborative production, and the surface of the circuit board may be worn during transportation, resulting in damage to the circuit and the circuit board. In addition, the circuit board is generally fixed directly to the inside of the equipment by bolts. When maintenance is required, the bolts need to be removed, and the threaded holes on the machine may become chipped, resulting in the bolts being unable to be removed more conveniently and even causing damage to the circuit board during removal. The purpose is to achieve the purpose of being able to more conveniently repair the circuit board when it is needed, without damaging the circuit board during disassembly, and effectively preventing the circuit board from being worn during production and transportation, thereby increasing the service life of the circuit board.

[0005] In order to solve the above technical problems, the utility model provides a collaboratively produced PCB circuit board, including a circuit board body: mounting holes are provided at the top of the circuit board body near the corners, a rotating seat is installed inside the mounting hole, a mounting seat is provided at the bottom of the rotating seat, an expansion screw is fixed to the bottom of the mounting seat, a threaded rod is fixed at the bottom of the rotating seat corresponding to the mounting seat, a threaded groove is provided on the outer wall of the mounting seat corresponding to the threaded rod, a protective layer is bonded to the outer wall of the circuit board body, the periphery of the protective layer is covered with a hard layer, and a solder resist layer is provided on the outer wall of the hard layer.

[0006] Furthermore, the rotating seat is adapted to the mounting hole, and both the rotating seat and the mounting seat are made of stainless steel.

[0007] Furthermore, the threaded rod is adapted to the threaded groove, and the threaded rod is threadedly connected to the threaded groove.

[0008] Furthermore, a plurality of electrical components are installed on the top of the circuit board body, and the electrical components are adapted to the circuit board body.

[0009] Furthermore, the protective layer is made of a three-proof paint material.

[0010] Furthermore, the hard layer is made of PECVD nano-coating material.

[0011] Furthermore, the solder resist layer is made of paint material.

[0012] The beneficial effects of the utility model are:

[0013] 1. Through the design of the rotating seat, mounting seat, expansion screw, threaded rod and thread groove, when the staff needs to install a collaboratively produced PCB circuit board, the staff can first put the expansion screw into the fixed groove inside the equipment. After the expansion screw is installed, the rotating seat can be rotated so that the rotating seat can drive the threaded rod to rotate, so that the threaded rod can be rotated into the inside of the thread groove until the threaded rod reaches the bottom of the thread groove. The rotating seat is continued to be rotated so that the rotating seat can drive the mounting seat to rotate together through the threaded rod, so that the expansion screw can be expanded and fixed inside the fixed groove, completing the installation of the circuit board body. When disassembly and maintenance are required, the staff only needs to rotate the rotating seat to separate the threaded rod from the thread groove, and the circuit board body can be removed relatively easily. It is more convenient when the circuit board needs to be repaired, and the circuit board will not be damaged during disassembly.

[0014] 2. Through the design of protective layer, hard layer and solder mask, in a collaborative production process of PCB circuit boards, the protective layer will form a transparent protective film after curing, which has excellent insulation, moisture-proof, anti-leakage, dust-proof, anti-corrosion, anti-aging, corona resistance and other properties. The hard layer can fully cover all parts of the circuit board, including sharp edges, cracks and inner surfaces, effectively preventing the invasion of moisture, dust and dirt, and can effectively avoid the impact of friction during transportation on the main body of the circuit board. The solder mask is mainly used to protect the circuit and copper surface. It is coated on the surface of the circuit board to form a protective layer to prevent the circuit and copper surface from being eroded by the external environment. It can effectively prevent the circuit board from being worn during production and transportation, thereby improving the service life of the circuit board.

A threaded rod 105 is fixed to the bottom of the rotating seat 102 corresponding to the mounting seat 103. A threaded groove 106 is provided on the outer wall of 3 corresponding to the threaded rod 105. The threaded rod 105 can rotate inside the threaded groove 106 and drive the mounting base 103 to rotate. A protective layer 2 is bonded to the outer wall of the circuit board body 1. The protective layer 2 can protect the circuit board body 1 from corrosion and can effectively prevent dust or moisture from contacting the circuit board body 1. The periphery of the protective layer 2 is covered with a hard layer 3. The hard layer 3 can effectively prevent the circuit board body 1 from being damaged during transportation. A solder resist layer 4 is provided on the outer wall of the hard layer 3. The solder resist layer 4 can prevent the circuit and copper surface on the circuit board body 1 from being eroded by the external environment.

[0025] Example 2:

[0026] like Figures 1 to 3 As shown, the rotating seat 102 is adapted to the mounting hole 101, and the rotating seat 102 and the mounting seat 103 are both made of stainless steel.

[0028] Several electrical components 107 are installed on the top of the circuit board body 1. The electrical components 107 are adapted to the circuit board body 1.
