[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0022] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.
[0023] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0024] In order to illustrate the technical solution described in this application, a specific embodiment is provided below for illustration.
[0025] Figure 1 A schematic structural diagram of a black shadow line cylinder drag plate provided in an embodiment of the present application is shown.
[0026] like Figure 1 As shown, the black shadow line dragging cylinder plate provided in the embodiment of the present application includes: a substrate 10, on which a copper wire pattern 11 is convexly provided, and the copper wire pattern 11 is designed as 9 sets, and the 9 sets are arranged in 3 rows and 3 columns. The lines on the set are used to remove the residual carbon on the roller, thereby reducing quality risks.
[0027] It should be understood that in the field of PCB technology, set refers to a graphic that is formed by piecing together multiple unit graphics in order to improve production efficiency, facilitate production, etc. It can also be called a puzzle board, which includes unit graphics, process edges, etc.
[0028] In each set, the copper wires are arranged in parallel, the width of each copper wire is greater than or equal to a first preset value, and the line spacing between adjacent copper wires is greater than or equal to a second preset value. For example, the first preset value and the second preset value can be determined according to the diameter of the roller, so that the lines on the set generate sufficient friction force on the roller to effectively remove the residual carbon on the roller, thereby reducing quality risks.
[0029] The length direction of the copper wires in different sets of each row is different, and the length direction of the copper wires in different sets of each column is different. With this arrangement, the carbon residue on the roller can be removed from different angles in any row or column direction, thereby improving the effect of removing the carbon residue on the roller and reducing quality risks.
[0030] In some embodiments, according to the diameter of the roller, the first preset value is set to 10 mil and the second preset value is set to 10 mil, so that the line on the set can generate sufficient friction on the roller to effectively remove the residual carbon on the roller, thereby reducing quality risks.
[0031] In some embodiments, the length direction of the copper wires in the three sets of each row includes a vertical direction, a left oblique direction, and a right oblique direction, and the length direction of the copper wires in the three sets of each column includes a vertical direction, a left oblique direction, and a right oblique direction. For example, the left oblique direction is a direction oblique to the left by 0 to 90 degrees relative to the vertical direction, and the right oblique direction is a direction oblique to the right by 0 to 90 degrees relative to the vertical direction. In other words, the length direction of the copper wires in the three sets of each row is a permutation and combination of the above three directions, and the length direction of the copper wires in the three sets of each column is a permutation and combination of the above three directions.
[0032] In some embodiments, the left oblique direction is a direction oblique 45° to the left relative to the vertical direction, and the right oblique direction is a direction oblique 45° to the right relative to the vertical direction. In this way, the left oblique direction and the right oblique direction differ by 90°, which can further improve the effect of removing residual carbon on the roller, thereby reducing quality risks.
[0033] In some embodiments, the copper line pattern 11 can be made by using related technologies, such as a subtractive process.
[0034] In some embodiments, the method for making the copper wire pattern 11 comprises the following steps:
[0035] (1) Provide a substrate 10. For example, the substrate 10 may be a plain copper plate, the thickness of the plain copper plate is 1.5 mm, and the initial copper thickness of the plain copper plate may be any value.
[0036] (2) In the electroplating process, the copper plate is plated to a copper thickness greater than or equal to 100um. It should be understood that because the black shadow process has a micro-etching system, the thicker the copper is plated, the more times the black shadow line cylinder plate can be used, that is, the longer its service life.
[0037] (3) Through exposure, development, etching and other processes, a Figure 1 The black shadow line shown in the figure drags the cylinder plate. Specifically, as Figure 1 As shown:
[0038] The whole panel is designed with 9 sets, 3 sets in each row, 3 rows in total, arranged in a 3*3 manner.
[0039] The first row of three sets is designed as follows:
[0040] The first set is designed with a line width of 10 mil, a line spacing of 10 mil, and all vertical lines;
[0041] The second set is 10mil line width, 10mil line spacing, and all left-slash lines;
[0042] The third set is a line width of 10 mil, a line spacing of 10 mil, and all lines are right-slashed.
[0043] The design of the three sets in the second row is as follows:
[0044] The first set is designed with a line width of 10 mil, a line spacing of 10 mil, and all left-slash lines;
[0045] The second set is 10mil line width, 10mil line spacing, and all right diagonal lines;
[0046] The third set is line width 10mil, line spacing 10mil, all vertical lines.
[0047] The design of the three sets in row 3 is as follows:
[0048] The first set is designed with a line width of 10 mils, a line spacing of 10 mils, and all right-slash lines;
[0049] The second set is 10mil line width, 10mil line spacing, and all vertical lines;
[0050] The third set is 10mil line width, 10mil line spacing, and all lines are left-slashed.
[0051] A black shadow line cylinder drag plate provided in an embodiment of the present application is designed through the above 9 sets. The placement positions of the direct lines of different sets are different. Through the pressure of the upper and lower rollers on the black shadow line cylinder drag plate, the lines on the set will generate friction on the rollers, which can effectively remove the residual carbon on the rollers, thereby reducing quality risks.
[0052] The embodiments described above are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application.
