Description

Technical Field

[0001] This application relates to the field of PCB manufacturing technology, and in particular to single boards, panel boards and working boards. Background Technology

[0002] With the continuous development of technology in the field of communication electronics, high-quality cost reduction solutions have become the ultimate goal in the consumer electronics hardware sector. Traditional printed circuit board (PCB) manufacturing requires the addition of wider process edges. The purposes are: 1) to add positioning holes to fix the position of the PCB board and to serve as an auxiliary means for mounting component fixtures; 2) to add mark points for PCB manufacturing testing, identification of component placement orientation, and to prevent mistaken identification. However, wider process edges lead to lower utilization rates of work boards, reduced output of work boards, and thus increased project costs. Utility Model Content

[0003] The purpose of this application is to disclose a single board, a panel, and a working board. The single board enables high utilization of the working board, increases the output of the working board, and reduces costs.

[0004] In a first aspect, this application discloses a single-layer board. The single-layer board includes a single-layer board body and a process edge connected to the single-layer board body; the single-layer board body includes a notch recessed inward from the edge of the single-layer board body; the process edge is at least partially located within the notch.

[0005] In some implementations, the process edge is completely located within the notch.

[0006] In some implementations, the notch is a chamfer on the body of the single panel.

[0007] In some embodiments, the projection of the single-board body and the notch onto the projection plane is rectangular, the projection plane is parallel to the single-board body, and there are two adjacent process edges.

[0008] In some embodiments, at least the process edge is rectangular, either the process edge or the notch.

[0009] In some implementations, the area of ​​the process edge is S, where S ≥ 6 mm × 3 mm.

[0010] In some embodiments, the notch includes a corner; the process edge includes a positioning hole and an edge away from the main body of the board. The distance between the center of the positioning hole and the edge is greater than the distance between the center of the positioning hole and the corner.

[0011] In some embodiments, a portion of the edge of the positioning hole is abutted against the sidewall of the corner.

[0012] In some embodiments, the process edge includes an edge away from the main body of the single board; the minimum distance between the edge of the positioning hole and the edge is d, where d ≥ 1 mm.

[0013] In some embodiments, the process edge includes a mark point and a positioning hole, and the minimum distance between the edge of the mark point and the edge of the positioning hole is n, where n ≥ 1 mm.

[0014] Secondly, this application discloses a panel. The panel comprises at least two of the aforementioned single veneers, and the process edge is located at the edge of the panel.

[0015] Thirdly, this application discloses a working board. The working board includes multiple single boards of any of the aforementioned types, which are spliced ​​together; or, the working board includes any of the aforementioned types of panels.

[0016] For the single board, the panel, or the work board, since the main body of the single board includes a notch and the process edge is at least partially located within the notch, the area of ​​the single board is smaller than the sum of the area of ​​the main body of the single board and the area of ​​the process edge. Therefore, the single board of this application occupies a smaller area, the output of the work board is larger, the utilization rate of the work board is improved, and a high-capacity, low-cost PCB structure manufacturing process is achieved.

[0023] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0024] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0025] See Figure 1 , Figure 2 and Figure 4 This application discloses a single board 1. Figure 1 The diagram illustrates two single-layer boards 1 forming a panel 10. Each single-layer board 1 includes a board body 11 and a process edge 12 connected to the board body 11. The process edge 12 can be connected by means such as connecting ribs. Figure 1 The diagram illustrates that each board 1 includes two process edges 12; however, the number of process edges 12 is not limited thereto. The board body 11 includes a notch recessed inward from the edge of the board body 11. The process edges 12 are at least partially located within the notch. Figure 1 and Figure 2 The diagram illustrates that the process edge 12 is completely within the notch. Therefore, the shape of the notch can be inferred from the shape of the process edge 12. In embodiments where the process edge 12 is completely within the notch, the relationship between the process edge 12 and the notch includes: 1) equal area and the same shape; 2) the same shape but unequal area; 3) different shapes and unequal areas. When the process edge 12 is partially within the notch, the shape of the process edge 12 can be determined according to requirements.

[0026] Because the process edge 12 is at least partially located within the notch, it is formally equivalent to the process edge 12 and the single-panel body 11 being interlocked. The notch is formed by an indentation from the edge of the single-panel body; this interlocking can also be understood as embedding. Therefore, the extent to which the process edge 12 is partially located within the notch is not limited, as long as the embedding effect is achieved. The shape of the process edge 12 and the shape of the notch are not limited to the rectangle with rounded corners shown in the figure. For example, the shapes of the process edge 12 and the notch can each be rectangles in a mathematical sense. The notch can also be other shapes, such as ellipses.

[0027] See Figure 5 In related technologies, the single board 1 includes a single board body 11 and a process edge 12 connected to the single board body 11. The single board body 11 does not have an inward recess to form a notch, and the process edge 12 is located outside the single board body 11. See also Figure 6Single board 1 constitutes panel 10. Figure 6 Each small square within the large solid line box represents Figure 5 As shown in the diagram, piece 10, therefore, Figure 6 The diagram shows 14 panels 10. Multiple panels 10 constitute the work board 100. Figure 5 In the related technologies shown, the area of ​​the single board 1 is at least the sum of the area of ​​the single board body 11 and the area of ​​the process edge 12, which occupies more area of ​​the working panel 100, resulting in low utilization of the working panel 100. This is not conducive to increasing production capacity and increases the manufacturing cost of printed circuit boards.

[0028] Figure 3 In this application, because the process edge 12 is at least partially located within the recessed notch of the single-panel body 11, the area of ​​the single-panel 1 is smaller than the sum of the area of ​​the single-panel body 11 and the area of ​​the process edge 12. Therefore, the area occupied by the single-panel 1 in this application is smaller. Figure 3 This illustration shows that the single board 1 of this application constitutes the panel 10, and multiple panels 10 constitute the working board 100. Figure 3 Each small square within the large solid line box represents Figure 1 As shown in the diagram, piece 10, therefore, Figure 3 The diagram shows 24 puzzle pieces.

[0029] Compare Figure 3 and Figure 6 This leads to the following insight: For a workboard of the same area, 100, Figure 3 The diagram shows 24 single boards 1. Figure 6 The diagram shows 14 individual boards 1. Therefore, the working board 100 of this application includes more individual boards 1, the output of the working board 100 is larger, the utilization rate of the working board 100 is improved, and a high-capacity, low-cost PCB structure manufacturing process is achieved.

[0030] When the process edge 12 is completely within the notch, the area of ​​the single board 1 is the sum of the area of ​​the single board body 11 and the area of ​​the notch, which is equivalent to not having to consider the area of ​​the process edge 12. Therefore, the output of the working board 100 is larger and the utilization rate of the working board 100 is higher.

[0031] See Figure 1 and Figure 2 Based on the position of the process edge 12, it can be inferred that the notch is the chamfer of the single-panel body 11. That is, for a component with an angle, a portion is cut off in the angled area to form the single-panel body 11. The space left by the cut-off portion is called the chamfer. At this time, the shape of the component with the angle is not limited to... Figure 2 The rectangle shown. More specifically, Figure 1 and Figure 2This can be understood as follows: Rectangular areas are cut off from each of the two adjacent corners of the rectangular component, and the remaining portion serves as the main body 11 of the single-board. (See also...) Figure 4 In some other embodiments, the single-board body 11 includes a side portion 111 located between adjacent corners, the side portion 111 having the notch, thereby allowing the process edge 12 to be located on the side portion 111. In this embodiment, the process edge 12 on the side portion 111 may only have test points, etc.

[0032] As described above, since the notch is a chamfered corner of the single-board body 11, the process edge 12 is at least partially located within the notch, i.e., at the corner of the single-board body 11. The process edge 12 facilitates the setting of positioning holes 121 and / or mark points 123. This makes it easier to position the single-board 1 in subsequent manufacturing processes and ensures that the single-board 1, the panel 10, or the work plate 100 are more secure. For example, the fixture can grip the single-board 1 at its corner, making the single-board 1 more secure. Figure 4 The process edge 12 shown is located on the side 111, which may cause the single board 1, panel 10, or work board 100 to tilt, resulting in an unstable grip. Furthermore, the process edge 12 is located at a corner and has a mark point, making identification and calibration more accurate. With the process edge 12 including positioning holes 121 and mark points 123, and combined with the inlay of the process edge 12, the problems of ensuring PCB board fabrication and mounting are solved under conditions of small single board area and a larger output of work board 100. Figure 1 and Figure 2 The diagram shows a single mark point, but the number of mark points 1, 2, and 3 is not limited to this.

[0033] See Figure 1 and Figure 2 The projection of the single-board body 11 and the notch onto the projection plane is rectangular. Here, "rectangle" can be understood as a rectangle in a mathematical sense, or it can be a rectangle with rounded corners; it just needs to be roughly rectangular. The projection plane is parallel to the single-board body, and there are two adjacent process edges 12. After the single boards 1 form a panel 10, a panel 10 includes four process edges 12. However, the number of process edges 12 in the panel 10 is not limited to four; it can be three, five, etc. In this case, the process edges 12 are not limited to being located at the corners of the panel 10.

[0034] As described above, since there are two adjacent process edges 12, when two single boards 1 are assembled into a panel 10, the four corners of the panel 10 are respectively equipped with the process edges 12, making the panel 10 or the work board more secure to grip and easier to position.

[0035] See Figure 1 , Figure 2 and Figure 4Of the process edge 12 and the notch, at least the process edge 12 is rectangular, including: 1) the process edge 12 and the notch are rectangular; 2) the process edge 12 is rectangular, and the notch is of other shapes. The rectangle can be a rectangle in a mathematical sense, or it can be... Figure 2 As shown, this includes a rectangle with rounded corners. (Combined) Figure 1 and Figure 2 The long side of the process edge 12 and the short side of the single board body 11 are located on the same side of the single board 1 (more specifically, aligned), and the short side of the process edge 12 and the long side of the single board body 11 are located on the same side of the single board 1; as a variation of the above embodiment, the short side of the process edge 12 and the short side of the single board body 11 may also be located on the same side of the single board 1, and the long side of the process edge 12 and the long side of the single board body 11 may be located on the same side of the single board 1.

[0036] As described above, since both the process edge 12 and the notch are rectangular and have regular shapes, it is easy to connect the process edge 12 to the single-board body 11, and it is also easy to remove the process edge 12 later. For example, the connecting ribs between the process edge 12 and the single-board body 11 are easier to connect.

[0037] See Figure 2 When the process edge 12 is rectangular, the area of ​​the process edge 12 is S, where S ≥ 6mm × 3mm, that is, S = length × width. For example... Figure 2 In the figure, L = 6mm and W = 3mm. Although the figure shows that the area of ​​the process edge 12 is approximately equal to the area of ​​the notch, in this embodiment, the area of ​​the process edge 12 can be smaller than the area of ​​the notch.

[0038] See Figure 2 and Figure 1 The notch includes a corner 112. In this embodiment, the single-board body 11 includes a first side 113 and a second side 114 that form the notch and are adjacent to each other. The tail of the first side 113 and the tail of the second side 114 are connected to form the corner 112, where the corner 112 is a rounded corner. In some embodiments, the corner can also be a right angle, an acute angle, an obtuse angle, or other shapes. The process edge 12 includes a positioning hole 121 and an edge 122 that is away from the single-board body 11. The distance between the center of the positioning hole 121 and the edge 122 is greater than the distance between the center of the positioning hole 121 and the corner 112. In short, compared with the edge 122 and the corner 112, the positioning hole 121 is closer to the corner 112.

[0039] As described above, the distance between the center of the positioning hole 121 and the edge 122 is greater than the distance between the center of the positioning hole 121 and the corner 112. The positioning hole 121 is closer to the corner 112. Therefore, the process edge 12 is closer to the single-board body 11, and the sum of their areas is smaller, resulting in a larger output of the workboard 100 and higher utilization of the workboard 100. Furthermore, the closer the positioning hole 121 is to the corner 112, and when a mark point 123 is provided on the process edge 12, it also helps to keep the mark point 123 further away from the positioning hole 121, thereby improving the accuracy of visual recognition and calibration of the single board 1, panel 10, or workboard 100.

[0040] See Figure 1 and Figure 2 In a further embodiment, a portion of the edge of the positioning hole 121 is in contact with the sidewall of the corner 112. This contact includes: 1) a portion of the edge of the positioning hole 121 is completely in contact with the sidewall of the corner 112; 2) a portion of the edge of the positioning hole 121 is in contact with a portion of the sidewall of the corner 112.

[0041] As described above, since part of the edge of the positioning hole 121 is in contact with the side wall of the corner 112, the positioning hole 121 can be made by combining the side wall of the corner 112 of the single board body 11 with the process edge 12. The sum of the area of ​​the process edge 12 and the area of ​​the single board body 11 is smaller (the sum of the areas is the smallest when the process edge 12 is completely within the notch). As a result, the output of the work board 100 is larger and the utilization rate is higher.

[0042] See Figure 2 The process edge 12 includes an edge 122 that is away from the main body 11 of the single board. The minimum distance between the edge of the positioning hole 121 and the edge is d, where d ≥ 1 mm;

[0043] As described above, since d≥1mm, the fixture can be prevented from damaging the single board 1, the splicing board 10, or the working board 100.

[0044] See Figure 2 The process edge 12 includes a mark point 123 and a positioning hole 121. The minimum distance between the edge of the mark point 123 and the edge of the positioning hole 121 is n, where n ≥ 1 mm, for example, 2 mm ≥ n ≥ 1 mm.

[0045] As described above, since n≥1mm, it is advantageous for the mark point 123 to be far apart from the positioning hole 121, thereby improving the accuracy of visual recognition and calibration of the single board 1, panel 10, or work board 100.

[0046] See Figure 1 and Figure 4Secondly, this application also discloses a panel 10. The panel 10 comprises at least two of the aforementioned single-layer boards 1, and the process edge 12 is located at the edge of the panel 10, only... Figure 1 The edge is an angle. Figure 4 The edges are straight.

[0047] See Figure 3 Thirdly, this application also discloses a working board 100. The working board 100 comprises multiple single boards 1 of any of the aforementioned types, and the multiple single boards 1 are spliced ​​together; this splicing is not limited to... Figure 1 The assembly shown. Alternatively, the work board 100 may comprise any of the aforementioned assembly boards 10.

[0048] With the above configuration, the work plate 100 has the following advantages: a larger output capacity and a higher utilization rate.

[0049] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
