Description

A method for optimizing hole positions in a flexible circuit board reinforcement and the reinforcement itself. Technical Field

[0001] This invention relates to the field of flexible circuit board auxiliary material processing technology, and in particular to a method for optimizing hole positions in flexible circuit board reinforcement components and the reinforcement component itself. Background Technology

[0002] In the production of flexible printed circuit boards (FPCBs), reinforcing components are typically used to improve the structural strength of local areas of the FPCB. To fit the FPCB, these reinforcing components usually require the machining of positioning holes, mounting holes, and other structural holes. However, adjacent structural holes on the reinforcing components are prone to damage and breakage, affecting the stability of the reinforcing component structure and consequently impacting the quality of the FPCB. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a method for optimizing the hole position processing of a flexible circuit board reinforcement and the reinforcement itself, so as to solve the problem that the reinforcement is easily damaged when processing adjacent mechanism holes.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0005] A method for optimizing the hole positions of a flexible circuit board reinforcement component includes: receiving a design layout drawing of the reinforcement component to be processed; identifying the distance between two adjacent mechanism holes in the design layout drawing; if the distance is less than or equal to a distance threshold, merging the two adjacent mechanism holes into an integrated hole to obtain an optimized layout drawing; and forming the integrated hole on the reinforcement component to be processed according to the optimized layout drawing.

[0006] To solve the above-mentioned technical problems, another technical solution adopted by the present invention is: a reinforcing member, which is prepared by the hole optimization processing method of a flexible circuit board reinforcing member as described above; the reinforcing member includes at least one integrated hole.

[0007] The beneficial effects of this invention are as follows: After receiving the design layout drawing of the reinforcement part to be processed, the invention identifies two adjacent mechanism holes in the design layout drawing and detects the distance between the two adjacent mechanism holes. When the detected distance is less than or equal to the distance threshold, the two adjacent mechanism holes are merged into one integrated hole to obtain an optimized layout drawing. Then, the integrated hole is formed on the reinforcement part to be processed according to the optimized layout drawing, thereby merging two adjacent mechanism holes into one integrated hole, eliminating the gap between the original two adjacent mechanism holes, solving the problem of hole wall deformation caused by the concentration of surrounding material force due to the existence of gaps, and thus avoiding the impact on the structural performance of the reinforcement part.

Detailed Implementation

[0009] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0010] In related technologies, reinforcing components adapted to flexible circuit boards typically require the machining of positioning holes, mounting holes, and other structural holes. Current methods for machining these structural holes primarily involve drilling or punching. However, when the spacing between adjacent structural holes is too small, the material around the holes experiences stress concentration, leading to hole wall deformation. This, in turn, causes problems such as easy breakage, fracture, and burr residue in the small-spacing area, affecting the structural performance of the reinforcing component. Furthermore, the deformed structural holes reduce subsequent assembly positioning accuracy, increase process errors, and result in low product yield.

[0011] To address the aforementioned technical problems, this invention provides a method for optimizing the hole positions of a flexible circuit board reinforcement and the reinforcement itself, solving problems such as deformation, damage, and low yield that occur when drilling / punching adjacent mechanism holes.

[0012] A method for optimizing the hole positions of a flexible circuit board reinforcement component includes: receiving a design layout drawing of the reinforcement component to be processed; identifying the distance between two adjacent mechanism holes in the design layout drawing; if the distance is less than or equal to a distance threshold, merging the two adjacent mechanism holes into an integrated hole to obtain an optimized layout drawing; and forming the integrated hole on the reinforcement component to be processed according to the optimized layout drawing.

[0013] As can be seen from the above description, the beneficial effects of the present invention are as follows: after receiving the design layout drawing of the reinforcing part to be processed, the two adjacent mechanism holes in the design layout drawing are identified and the distance between the two adjacent mechanism holes is detected. When the detected distance is less than or equal to the distance threshold, the two adjacent mechanism holes are merged into one integrated hole to obtain an optimized layout drawing. Then, the integrated hole is formed on the reinforcing part to be processed according to the optimized layout drawing, thereby realizing the merging of the two adjacent mechanism holes into one integrated hole, eliminating the gap between the original two adjacent mechanism holes, solving the problem that the hole wall of the two adjacent mechanism holes is deformed due to the stress concentration of the surrounding material due to the existence of gaps, thus avoiding the impact on the structural performance of the reinforcing part.

[0014] In one embodiment of this application, the step of identifying the distance between two adjacent mechanism holes in the design layout drawing includes: obtaining the material type of the reinforcement to be processed; and obtaining a preset distance threshold corresponding to the reinforcement to be processed based on the material type.

[0015] As described above, this embodiment establishes a correspondence between different material types and distance thresholds. Before identifying the spacing between two adjacent mechanism holes, a corresponding preset distance threshold is obtained based on the material type of the reinforcement to be processed. Then, the spacing is judged based on this distance threshold. Since the distance threshold corresponds to the material type, the set distance threshold is more in line with the material characteristics of the current reinforcement to be processed, thus meeting the requirements of different materials for spacing settings.

[0016] In one embodiment of this application, the method further includes: if the material type is epoxy glass cloth laminate, then the distance threshold is 0.25mm.

[0017] As described above, setting the distance threshold for epoxy glass cloth laminate material to 0.25mm can effectively solve the problems of deformation, breakage, and low yield that occur during drilling / punching when the spacing between adjacent mechanism holes of epoxy glass cloth laminate reinforcement is ≤0.25mm.

[0018] In one embodiment of this application, the method further includes: if the material type of the reinforcement to be processed is not obtained, the distance threshold is 0.3 mm.

[0019] As described above, when the material type of the reinforcement to be processed is not obtained, setting the distance threshold to 0.3mm provides a wide range of distance thresholds, which can solve the problem that damage easily occurs between adjacent mechanism holes in most materials.

[0020] In one embodiment of this application, identifying the spacing between two adjacent mechanism holes in the design layout drawing includes: traversing the mechanism holes in the design layout drawing, and for each target mechanism hole traversed, obtaining the adjacent mechanism hole with the closest spacing to the target mechanism hole as the center and the distance threshold as the radius, and taking the target mechanism hole and the adjacent mechanism hole as two adjacent mechanism holes.

[0021] As described above, by traversing the mechanism holes in the design layout drawing and taking the target mechanism hole and its nearest neighboring mechanism hole as the two adjacent mechanism holes, the identification of two adjacent mechanism holes can be achieved.

[0022] In one embodiment of this application, after determining the target mechanism hole and the adjacent mechanism hole as two adjacent mechanism holes, the method further includes: skipping the traversal of the adjacent mechanism holes.

[0023] As described above, since the identification process uses a distance threshold as the radius, when an adjacent mechanism hole is identified as the closest mechanism hole to the target mechanism hole, it indicates that the target mechanism hole is also the closest adjacent mechanism hole. Therefore, skipping the traversal of adjacent mechanism holes can improve the identification efficiency.

[0024] In one embodiment of this application, merging two adjacent mechanism holes into one integrated hole includes merging two adjacent mechanism holes into one waist-shaped hole.

[0025] As can be seen from the above description, by merging two adjacent mechanism holes into one waist-shaped hole, the original function of the mechanism hole can be preserved, but the two adjacent mechanism holes are integrated, and problems such as damage and breakage are likely to occur between adjacent mechanism holes.

[0026] In one embodiment of this application, merging two adjacent mechanism holes into a waist-shaped hole includes: pulling the two adjacent mechanism holes together along the spacing direction to obtain the waist-shaped hole, and making the radii at both ends of the waist-shaped hole consistent with the original radii of the two adjacent mechanism holes.

[0027] As described above, when forming the waist-shaped hole, the two adjacent mechanism holes are stretched together along the spacing direction, and the radii at both ends of the waist-shaped hole are consistent with the original radii of the two mechanism holes, which can effectively preserve the original size and function of the mechanism holes.

[0028] Another embodiment of the present invention provides a reinforcing member 100, which is prepared by the hole optimization processing method of a flexible circuit board reinforcing member as described above; the reinforcing member 100 includes at least one integrated hole 101.

[0029] As described above, by identifying two adjacent mechanism holes and merging them into a single integrated hole 101 based on the existing reinforcement design layout drawings, an optimized layout drawing is obtained. Then, the integrated hole 101 is formed on the reinforcement to be processed according to the optimized layout drawing, thereby merging two adjacent mechanism holes into a single integrated hole 101, eliminating the gap between the original two adjacent mechanism holes, and solving the problem of hole wall deformation caused by the concentration of surrounding material stress due to the existence of gaps. This avoids the impact on the structural performance of the reinforcement 100.

[0030] In one embodiment of this application, the distance from the center of the integrated hole 101 to the edges of the two ends of the integrated hole 101 is less than or equal to 0.15 mm.

[0031] As described above, the distance from the center of the integrated hole 101 to the edges of its two end holes is less than or equal to 0.15 mm, that is, the distance between two adjacent mechanism holes is less than or equal to 0.3 mm, which can solve the problem that adjacent mechanism holes are prone to breakage in most materials.

[0032] Embodiment 1 of the present invention is as follows: Referring to Figure 1, a method for optimizing the hole positions of a flexible circuit board reinforcement includes: S1, receiving the design layout drawing of the reinforcement to be processed; for example, taking the reinforcement to be processed in Figure 2 as an example, the design layout drawing shown in Figure 2 is obtained.

[0033] S2. Identify the spacing between two adjacent mechanism holes in the design layout drawing. If the spacing is less than or equal to a distance threshold, merge the two adjacent mechanism holes into one integrated hole to obtain an optimized layout drawing.

[0034] The process includes step S02 before execution S2: S02, obtaining the material type of the reinforcing component to be processed; obtaining a preset distance threshold corresponding to the reinforcing component to be processed based on the material type; for example, the preset correspondence is: material type epoxy glass cloth laminate (FR4) - distance threshold 0.25mm; polyimide (PI) - distance threshold 0.2mm; electromagnetic shielding film - distance threshold (film spacing) 0.25mm; other materials - distance threshold 0.3mm. Taking the obtained material type of the reinforcing component to be processed as epoxy glass cloth laminate as an example, the obtained distance threshold is 0.25mm; at the same time, when the material type of the reinforcing component to be processed is not obtained, the distance threshold is set to 0.3mm.

[0035] When identifying the spacing between two adjacent mechanism holes in the design layout drawing, the following method is used: S21, traverse the mechanism holes in the design layout drawing. For each target mechanism hole encountered, using the target mechanism hole as the center and the distance threshold as the radius, obtain the adjacent mechanism hole with the closest spacing to the target mechanism hole, and regard the target mechanism hole and the adjacent mechanism hole as two adjacent mechanism holes. At the same time, skip the traversal of the adjacent mechanism holes.

[0036] Taking Figure 2 as an example, the design layout drawing includes four mechanism holes. If the mechanism hole in the upper left corner is the target mechanism hole, then the radius of the mechanism hole itself is increased by 0.25mm (distance threshold) as the detection radius, and the mechanism holes near this mechanism hole are detected. For example, if the radius of the mechanism hole itself is 0.5mm, then the detection radius is 0.75mm. The nearest adjacent mechanism hole to the target mechanism hole is found to be the mechanism hole in the lower left corner. At this point, the two mechanism holes on the left are identified as adjacent mechanism holes, and the identification of the mechanism hole in the lower left corner is skipped. Then the mechanism hole in the upper right corner is detected and identified as the target mechanism hole. Similarly, the nearest adjacent mechanism hole to the target mechanism hole is found to be the mechanism hole in the lower right corner. At this point, the two mechanism holes on the right are identified as adjacent mechanism holes. This completes the traversal of all mechanism holes. A total of two pairs of adjacent mechanism holes were identified.

[0037] S22. If the distance between two mechanism holes is detected to be 0.2mm, where 0.2mm ≤ 0.25mm (threshold distance), then the two adjacent mechanism holes are merged into one integrated hole to obtain an optimized layout drawing. In this embodiment, the two adjacent mechanism holes are merged into one waist-shaped hole; that is, the two adjacent mechanism holes on the left side are merged into one waist-shaped hole, and the two adjacent mechanism holes on the right side are also merged into one waist-shaped hole. When merging into a waist-shaped hole, the two adjacent mechanism holes are stretched along the spacing direction to obtain the waist-shaped hole, and the radii at both ends of the waist-shaped hole are consistent with the original radii of the two adjacent mechanism holes. Figure 3 shows a schematic diagram of the formed waist-shaped hole.

[0038] S3. Form the integrated hole on the reinforcement part to be processed according to the optimized layout drawing. For example, use drilling or punching processes to obtain a reinforcement part with a waist-shaped hole. When processing the waist-shaped hole, the processing is based on a drill bit / grooving tool. The tolerance of the waist does not affect the performance of the reinforcement part, but it is necessary to remove the burrs of the waist-shaped hole to avoid scratching or puncturing the product.

[0039] Figure 2 shows the traditional design: the epoxy glass cloth laminate reinforcement has two circular mechanism holes with a center-to-center distance of 0.2mm (≤0.25mm). After traditional drilling, the hole wall deformation rate is >10%, and the yield is only 82%. Figure 3 shows the design of this invention: after the above-mentioned double circular holes are drawn into oblong holes and processed by punching, the hole walls are free of deformation and burrs, the material is undamaged, and the yield is improved to 98%. During subsequent assembly, the positioning error is controlled within ±0.05mm, meeting the process requirements. The mechanism holes on the reinforcement are usually used for connection with the flexible circuit board, such as when the reinforcement is attached to the surface of the flexible circuit board. Since the flexible circuit board itself also has drilled holes, changing the circular holes on the reinforcement to oblong holes does not affect the assembly of the reinforcement and the flexible circuit board. The reinforcement mainly serves a supporting function.

[0040] Please refer to Figure 3, which shows a reinforcing member 100 prepared based on the above method. The reinforcing member 100 includes at least one integrated hole 101. The distance from the center of the integrated hole 101 to the edges of both ends of the integrated hole 101 is less than or equal to 0.15 mm.

[0041] In summary, this invention provides a method for optimizing the hole positions of a flexible circuit board reinforcement component and the reinforcement component itself. By identifying two adjacent structural holes in the design layout drawing, two structural holes with a spacing less than or equal to a distance threshold are merged into a single oblong hole. This ensures that the positioning accuracy of the oblong hole is consistent with the original double circular holes, without affecting subsequent assembly processes. This eliminates the problem of stress concentration at the hole positions caused by small spacing while maintaining the structural integrity of the reinforcement component, reducing deformation and burrs, and increasing the processing yield to over 98%. Furthermore, the processing steps are simplified from processing two circular holes to processing one oblong hole, reducing processing steps and costs.
