Description

Technical Field

[0001] This invention relates to a fixture, processing method, and PCB board for improving horizontal line scratches on PCB gold-coated panels, belonging to the field of printed circuit board manufacturing. Background Technology

[0002] In the manufacturing process of printed circuit boards (PCBs), the gold-plated side panel is typically used as a crucial functional area for electrical connections or signal transmission, and is widely applied to connectors, gold fingers, or other high-reliability connection components. Due to the high surface precision requirements and material costs associated with the gold-plated side panel, its surface quality directly affects the conductivity of the PCB and the overall quality of the product.

[0003] In existing PCB manufacturing processes, PCBs typically move continuously on a machine via a conveyor mechanism. During this process, the bottom surface or a portion of the PCB inevitably comes into contact with the machine's support surface or the conveyor structure. When the PCB has a gold-plated panel, this area is prone to scratches during horizontal machining and conveying due to friction, foreign object inclusions, or uneven stress.

[0004] In existing technologies, to reduce scratches on gold panels, improvements are typically made by enhancing machine cleaning, optimizing transmission parameters, or adding protective measures to the gold panel surface. However, these methods often depend on operating procedures or equipment conditions, resulting in poor stability and making it difficult to effectively prevent scratches on gold panels during horizontal line processing. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art. In the existing PCB production process, when the PCB is conveyed and processed in the horizontal line processing equipment, the gold panel area is prone to contact with the machine support surface or conveying structure, which will cause scratches and affect the surface quality and reliability of the gold panel.

[0006] To solve the above-mentioned technical problems, the present invention is implemented using the following technical solution: In a first aspect, a fixture is provided for improving scratches on PCB gold panels during horizontal line processing, comprising: The frame section encloses and forms an internal space for accommodating the PCB. A support structure is provided on the inner side of the frame portion to support the PCB. The support structure includes multiple support points, which are equidistantly arranged on the inner side of the frame.

[0007] Furthermore, the overall thickness of the fixture is not less than 10 mm.

[0008] Furthermore, the distance between the inner edge of the frame portion and the edge of the PCB is not less than 10mm.

[0009] Furthermore, the support points are respectively set along the long and short sides of the frame portion; Three support points are provided at each long side; Two support points are set at each short side.

[0010] Furthermore, the length of the support point is not less than 25mm; the width of the support point is not less than 20mm.

[0011] Furthermore, the width of the border portion is not less than 30mm.

[0012] Furthermore, the fixture is made of acrylic material.

[0013] Secondly, a processing method for improving the scratches on PCB gold panels during horizontal line processing is provided, including the following steps: Before the PCB enters the horizontal line processing equipment, the PCB is placed in the fixture described in any one of claims 1 to 7 for improving the scratches on the PCB gold panel during horizontal line processing; The fixture and PCB are brought into the horizontal line processing equipment as a whole; After the horizontal lines of the PCB are processed, the entire PCB is removed from the processing equipment.

[0014] Thirdly, a PCB board is provided, which is prepared by the processing method described in the second aspect to improve the scratching of the PCB gold panel during horizontal line processing.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: 1. This invention utilizes a jig with a frame and support structure to support the PCB during horizontal line processing, so that the PCB is in a state of being supported as a whole during processing and transportation. This allows the gold panel of the PCB to be separated from the machine support surface, avoiding direct contact between the gold panel and the machine. This effectively reduces or eliminates the problem of gold panel scratches caused by friction, local stress, or foreign object inclusion.

[0016] 2. This invention provides uniform support for the PCB during horizontal line processing by setting multiple equally spaced support points on the inner side of the fixture and arranging them along the long and short sides of the frame. This improves the stability of the PCB during transport and reduces surface damage caused by board shaking or sinking. At the same time, the fixture adopts a frame structure with a certain thickness and width, which can be directly applied to existing production lines without changing the structure of existing horizontal line processing equipment.

[0019] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments and specific features in the embodiments are detailed descriptions of the technical solution of the present application, rather than limitations thereof. In the absence of conflict, the embodiments and technical features in the embodiments can be combined with each other.

[0020] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0021] In one specific embodiment, such as Figure 1 As shown, a fixture for improving the scratches on PCB gold panels during horizontal line processing is provided, including a frame portion and a support structure disposed inside the frame portion.

[0022] The frame portion encloses an internal space for accommodating the PCB. In use, the entire PCB is placed inside the fixture, and the fixture supports the PCB.

[0023] The support structure includes multiple support points, which are equidistantly arranged on the inner side of the frame to provide distributed support for the PCB, thereby preventing the PCB from sinking locally or coming into contact with the machine surface during horizontal line processing. By supporting the PCB with support points, the PCB is in a state of being supported as a whole during the processing. In particular, the gold panel of the PCB is separated from the support surface of the machine, which structurally avoids direct friction between the gold panel and the machine, thereby reducing the risk of scratches.

[0024] In this embodiment, as Figure 2As shown, the overall thickness of the fixture is not less than 10mm; to ensure that the fixture has sufficient height in the horizontal processing equipment so that the PCB can be detached from the machine surface under load; at the same time, the distance between the inner edge of the frame and the edge of the PCB is not less than 10mm, so as to avoid the frame from squeezing or interfering with the edge of the PCB, and to provide space for the arrangement of support points.

[0025] Furthermore, the support points are respectively set along the long and short sides of the frame, wherein 3 support points are set at each long side and 2 support points are set at each short side, so that the PCB is supported in all four directions, thereby improving the stability of the PCB during the horizontal line processing. Specifically, the length of the support point is not less than 25mm and the width is not less than 20mm; so that a contact area is formed between the support point and the edge of the PCB, avoiding excessive local stress due to the small contact area.

[0026] In this embodiment, the width of the frame portion is not less than 30mm; this is to ensure that the fixture does not deform during long-term operation in the horizontal line processing equipment; specifically, the fixture is made of acrylic material, which makes the fixture easy to process and lightweight, and suitable for repeated use on the PCB production line.

[0027] This embodiment also provides a processing method to improve the scratching of PCB gold panels during horizontal line processing; such as Figure 3 As shown, in specific implementation, before the PCB enters the horizontal line processing equipment, the PCB is first placed in the internal space of the aforementioned fixture, so that the PCB is supported by the fixture's support points; then, the fixture and the PCB are transported and processed as a whole into the horizontal line processing equipment; after the PCB completes the horizontal line processing, the PCB is removed from the processing equipment as a whole, and then subsequent processes are carried out.

[0028] This embodiment also provides a PCB board, which is prepared using the above-described processing method to improve the scratching of the PCB gold panel during horizontal line processing. Because the PCB is supported and carried as a whole by a fixture during horizontal line processing, preventing direct contact between the gold panel and the machine tool, the resulting PCB board has better surface integrity and consistency in the gold panel area.

[0029] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
