[0003] In the packaging process of the circuit board, the substrate is inevitably damaged to the copper layer of the functional area of the substrate due to the collision of external force around or cutting single forming in some links of process transportation or manufacturing, resulting in the exposure of the copper layer of the copper layer, and the exposed copper will be separated due to the heat effect in the subsequent plate and actual use, causing short circuit risk, resulting in the failure of the circuit board. The existing circuit board design does not consider the above risks, so

[0004] It should be noted that the introduction to the technical background above is only to facilitate the clear and complete description of the technical scheme of the utility model, and to facilitate the understanding of the technical personnel in the art. The above technical scheme cannot be considered as known by the technical personnel in the art only because it is described in the background technology part of the utility model. CONTENT OF THE UTILITY MODEL

[0005] The utility model aims at providing a collision-proof circuit board, which can set a reinforcing part to fill the corner retreat of the copper layer, so that the reinforcing part plays a buffering role on the copper layer, avoiding direct damage to the copper layer.

[0006] In order to achieve the above purpose, the utility model discloses a collision-proof circuit board, which comprises:

[0010] Among them, the copper layer is provided with a retreat at the corner, which is away from the direction of the transition mechanism, and the transition mechanism is filled with a reinforcing part matching the size of the retreat of the copper layer at the retreat of the copper layer;

[0011] The reinforcing part has a size sufficient to extend along the horizontal direction, so that the reinforcing part is used for buffering and avoiding direct exposure of the corner of the copper clad layer when the corner of the anti-collision circuit board is cut or collided.

[0012] As further description of the above technical solution, the reinforcing part is arranged as an isosceles triangle with equal side length along two outer sides of the copper clad layer.

[0013] As further description of the above technical solution, the number of the reinforcing parts is multiple, and each corner of the copper clad layer is provided with a reinforcing part.

[0014] As further description of the above technical solution, the sizes of the multiple reinforcing parts of each corner of the copper clad layer are matched.

[0032] In order for those skilled in the art to better understand the technical solutions in the present specification, the technical solutions in the embodiments of the present specification will be described clearly and completely below in conjunction with the drawings in the embodiments of the present specification. Obviously, the described embodiments are only some of the embodiments of the present specification, not all. Based on the embodiments in the present specification, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the present specification.

[0033] The following is to illustrate the embodiments of the present application by specific embodiments. Those skilled in the art can understand the advantages and effects of the present application from the disclosed content of the present specification. The present application can be implemented or applied by other different specific embodiments, and each detail in the present specification can be modified and changed in various ways based on different viewpoints and applications without departing from the concept of the present application. In addition, the drawings of the present application are only simple schematic illustrations, not the depiction of actual size, and the prior declaration is made. The following embodiments will further illustrate the related technical content of the present application in detail, but the disclosed content is not used to limit the protection scope of the present application.

[0034] It should be understood that although the terms "first", "second", "third" and the like can be used herein to describe various components or signals, these components or signals should not be limited by these terms. These terms are mainly used to distinguish one component from another component, or one signal from another signal. In addition, the term "or" used herein can include any one or more combinations of the associated listed items.

[0035] Referring to Figures 1-3 A kind of anti-collision circuit board for the embodiment, wherein the anti-collision circuit board includes:

[0036] Copper layer 1, copper layer 1 extends along the horizontal direction, and the outer surface of copper layer 1 is covered with paint layer 5;

[0037] Transition mechanism 2, transition mechanism 2 is arranged at the periphery of copper layer 1 along the horizontal direction, and transition mechanism 2 is arranged adjacent to copper layer 1;

[0038] Strengthening mechanism 3, strengthening mechanism 3 is arranged at the periphery of transition mechanism 2 along the horizontal direction, and strengthening mechanism 3 is arranged adjacent to transition mechanism 2;

[0039] Wherein, copper layer 1 is provided with retreat at the corner, away from the direction of transition mechanism 2, and transition mechanism 2 is filled with reinforcing part 4 matching the size at the retreat of copper layer 1;

[0040] Reinforcing part 4 has sufficient size extending along the horizontal direction, so that reinforcing part 4 is used to buffer and avoid direct exposure of the corner of copper layer 1 when the corner of anti-collision circuit board is cut or collided.

[0041] For the above structure, only the corner position of copper layer 1 corresponding to the size is cut off during production to form retreat, and the corner position of copper layer 1 is filled with reinforcing part 4 when covering transition mechanism 2, so that the dense connection between copper layer 1 and transition mechanism 2 is still formed.

[0042] Through the above structure, when anti-collision circuit board is accidentally cut or collided, causing anti-collision circuit board to form inward stress from the corner position, at this time, due to the existence of reinforcing part 4, it plays a further transition role to the internal copper layer 1 entity part, and bears the influence that the original position of copper layer 1 should bear, therefore, even under the influence of the above, the corner of copper layer 1 does not occur paint layer 5 off phenomenon due to retreat, which avoids the occurrence of copper exposure phenomenon of copper layer 1, resulting in the risk of short circuit caused by copper ionization after the heat effect of circuit board.

[0043] Meanwhile, the copper clad layer 1 in the embodiment only needs to be cut at the corners, has less influence on the internal structure layout, the reinforcing part 4 is easy to process, the process cost is low, and the yield after the process is high.

[0044] Further, the reinforcing part 4 is arranged in the shape of an isosceles triangle with equal side lengths along two outer sides of the copper clad layer 1. Specifically, the apex of the reinforcing part 4 is arranged as the center directly subjected to force, and the two side lengths of the reinforcing part 4 are equal, so that the force is more balanced, and the internal copper clad layer 1 is prevented from being damaged by excessive stress.

[0045] Further, the number of the reinforcing part 4 is set to be multiple, and the reinforcing part 4 is arranged at each corner of the copper clad layer 1. Specifically, the multiple reinforcing parts 4 at each corner of the copper clad layer 1 are matched in size, so that full coverage of the copper clad layer 1 is achieved, and the situation that the copper clad layer 1 is knocked and has no reinforcing part 4 to buffer is avoided to the greatest extent. In the embodiment, the copper clad layer 1 is arranged in the shape of a rectangle extending along a plane, the number of the reinforcing part 4 is set to be four at four corners of the rectangle, and each reinforcing part 4 is arranged in the shape of an isosceles right triangle. The isosceles right triangle has the best stress resistance and is easy to process, and only needs to be cut at the corners of the copper clad layer 1.

[0046] Further, the copper clad layer 1 is provided with pads (such as circular structures in an array in Figure 1 ), and the reinforcing part 4 is arranged to avoid the pads. Specifically, since the reinforcing part 4 in the embodiment is only arranged at the corner position, that is, the main body part of the copper clad layer 1 is still used to arrange a functional structure, and the reinforcing part 4 is only arranged at the corner and does not affect the layout of the functional structure, and the corner is the most easily processed and has the best effect.

[0047] Further, the width of the transition mechanism 2 is matched with the width of the reinforcing mechanism 3, that is, the anti-collision circuit board in the embodiment takes the copper clad layer 1 as the main body, and the structure buffer level is uniform.

[0048] Further, referring to Figure 2 , 3 , the paint layer 5 is arranged to cover the reinforcing part 4 in the horizontal direction. Specifically, the surface of the reinforcing part 4 is still covered with the full-surface paint layer 5 structure similar to the existing circuit board without the reinforcing part 4, which is helpful for aesthetics, and the paint layer 5 is flatly laid on the copper clad layer 1, and the paint layer 5 has good structural strength.

[0049] The above disclosed content is only a preferred and feasible embodiment of the utility model, and does not limit the application patent range of the utility model, so that any equivalent technical change made by applying the utility model specification and drawing content is included in the application patent range of the utility model.

[0050] Various embodiments in the present specification are described in progressive manner, and the same or similar parts between various embodiments can refer to each other, and each embodiment focuses on the difference from other embodiments.

[0051] Although the present application is described through embodiments, those skilled in the art know that there are many modifications and variations of the present application without departing from the spirit of the present application, and it is intended that the appended embodiments include these modifications and variations without departing from the present application.
