Technical Field

[0001] This utility model relates to the field of circuit board technology, specifically to a single-sided etched circuit board. Background Technology

[0002] The main function of single-sided etched circuit boards is to use strong acids or alkalis to react with the copper surface of the circuit board, etching away the non-circuit copper and retaining the copper layer at the circuit location, thereby achieving electrical connection between electronic components. By controlling parameters such as the concentration, temperature, and etching speed of the etching solution, the required conditions can be met.

[0003] Single-sided etched circuit boards are characterized by their simple manufacturing process and low cost, making them suitable for less complex electronic products. However, during current circuit board manufacturing, it is impossible to position them properly, which can easily lead to displacement during the etching process, reducing efficiency and affecting the etching effect.

[0004] Therefore, a novel single-sided etched circuit board is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a single-sided etched circuit board to solve the problem mentioned in the background art that the circuit board cannot be positioned during processing and production, and that the etching process is prone to displacement, which reduces efficiency and affects the etching effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a single-sided etched circuit board, comprising a copper-clad plate and a circuit board substrate, wherein the copper-clad plate is located in front of the circuit board substrate, and positioning components for easy processing are provided at the four corners of the copper-clad plate.

[0007] The positioning component includes a positioning disc. Positioning holes are provided through the four corners of the copper-clad board. Multiple sets of positioning discs are provided and are respectively fixedly connected to the front and rear ends of the four corners of the copper-clad board. The positioning disc covers the outer ring of the positioning hole. A circular frame is fitted to the inner wall of the positioning hole. A protective inner pad is fixedly connected to the inner wall of the circular frame. Multiple sets of connecting outer plates are fixedly connected to the outer front end of the circular frame. A fixing groove is provided through the inner side of the connecting outer plate.

[0008] Preferably, the front end of the positioning disc is fixedly connected to multiple sets of insert plates, each insert plate corresponding to a fixed groove, the insert plate penetrating the interior of the fixed groove and engaging with the groove on the inner wall of the fixed groove.

[0009] Preferably, the copper-clad board has multiple sets of heat dissipation holes that are evenly distributed on both sides of the copper-clad board.

[0010] Preferably, a dust filter is attached to the rear end of the copper-clad board, a second external connector is fixedly connected to the rear end of the left side of the copper-clad board, and a first external connector is fixedly connected to the rear end of the right side of the copper-clad board.

[0011] Preferably, a second mounting plate is fixedly connected to the left side of the dust filter, and a first mounting plate is fixedly connected to the right side of the dust filter. The second mounting plate is inserted into the interior of the second external connector, and the first mounting plate is inserted into the interior of the first external connector.

[0012] Preferably, two sets of fastening bolts are provided through each of the four corners of the copper-clad board, and two sets of positioning sleeves are provided through each of the four corners of the front end of the circuit board substrate.

[0013] Preferably, the fastening bolt is threaded inside the positioning sleeve, and a knob is fixedly connected to the front end of the fastening bolt.

[0014] Preferably, sealing side gaskets are fixedly connected to the front ends of both sides of the circuit board substrate, and sealing bottom gaskets are fixedly connected to the top and bottom of the front end of the circuit board substrate. The front ends of the sealing side gaskets and sealing bottom gaskets are in contact with the rear end of the copper clad plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the single-sided etched circuit board not only realizes the positioning function and the rapid heat dissipation function, but also realizes the splicing and fixing function;

[0016] The system includes a positioning disc, positioning holes, a circular frame, a protective inner pad, a connecting outer plate, a fixing groove, and an insert plate. Two sets of positioning discs are fixed to the outer rings at both ends of the positioning holes, covering the periphery of the positioning holes. The circular frame penetrates the interior of the positioning holes. Multiple sets of connecting outer plates extend outward and fit against the surface of the positioning discs. The insert plate is fixed inside the fixing groove using an interlocking connection method, thus fixing the circular frame in all directions. During the etching process, the positioning holes facilitate the positioning of the four corners of the copper-clad board, effectively preventing the copper-clad board from shifting and reducing the etching effect. The protective inner pad provides strong protection for the inner wall of the positioning holes, avoiding friction damage that may affect later use.

[0017] The copper-clad board is equipped with a dust filter, heat dissipation holes, a first external connector, a second external connector, a first mounting plate, and a second mounting plate. The dust filter is placed against the rear end of the copper-clad board. By opening multiple sets of heat dissipation holes, the circuit of the copper-clad board is precisely cooled, improving the heat dissipation and protection effect, extending its service life. The dust filter also deeply removes impurities from the flowing air, ensuring that the copper-clad board and the circuit board substrate are within a safe range. The first mounting plate and the second mounting plate, which are fixed on both sides of the dust filter, are inserted and fixed in the first external connector and the second external connector using a plug-in connection method, which quickly fixes both sides of the dust filter and strengthens the connection between the dust filter and the copper-clad board.

[0018] By incorporating a sealing base gasket, sealing side gaskets, fastening bolts, knobs, and positioning sleeves, positioning sleeves are installed at all four corners of the circuit board substrate. The fastening bolts are rotated into the positioning sleeves using the threaded direction on their surfaces, enhancing the firmness between the copper clad laminate and the circuit board substrate, facilitating positioning and installation, and optimizing the connection method between structures. The sealing side gaskets and sealing base gaskets work together to provide sealing protection for the gaps between the copper clad laminate and the circuit board substrate, improving safety.
