In addition, the rise of flexible printed circuit board technology has also brought new possibilities to fields such as wearable devices.

[0003] During the use of existing circuit boards, usually to avoid the situation that when the user touches the circuit board by hand, the static electricity carried by the human body forms a high voltage at both ends of the capacitor, causing the capacitor to be breakdown damaged. The existing circuit boards are provided with an insulating layer inside, and when packaged and transported, an anti-static protective film is coated on the outer layer to enhance the anti-static effect and safety protection of the circuit board. However, during the actual use process, the user will inevitably touch the circuit board, so there are still certain safety hazards and cause certain economic property losses. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a PCB circuit board with blind vias to solve the technical problem of poor anti-static effect of the circuit board in the prior art.

[0006] By adopting the above technical solution, when the user performs the operation of taking the circuit board main body, the user can avoid directly contacting the circuit board main body by holding or pinching the first support piece, the second support piece, and the third support piece. This method effectively prevents damage or contamination that may be caused by direct contact.

[0007] Furthermore, the first support piece, the second support piece, and the third support piece are in a strip-shaped structure, which is used to provide the acting force points for the user on the circuit board main body.

[0011] Furthermore, a plurality of friction pieces are provided on the top surface of the first support piece, and they are arranged at equal intervals linearly along the width line of the first support piece.

[0012] By adopting the above technical solution, the plurality of friction pieces increase the friction force between the user and the support piece, making the grip more stable and reducing the risk of slipping or dropping the hand during the operation.

[0013] Furthermore, the material of the friction piece is a rubber strip, and the materials of the first support piece, the second support piece, and the third support piece are all epoxy resins.

[0015] Furthermore, a plurality of easy-to-break holes are provided at the connection between the connecting piece and the circuit board body.

[0016] By adopting the above technical solution, the plurality of easy-to-break holes enable the user to easily remove the support mechanism from the circuit board body when needed. The setting of the easy-to-break holes reduces the difficulty during the removal process and improves the operation convenience.

[0017] Furthermore, blind holes and mounting holes are provided on the surface of the circuit board body.

[0018] By adopting the above technical solution, the blind holes help to optimize the circuit layout, improve the overall performance and reliability of the circuit board. The setting of the blind holes enables the circuit board to achieve more complex circuit connections within a limited space, while reducing the wiring difficulty and cost.

[0019] In summary, the present utility model mainly has the following beneficial effects:

[0020] 1. Through the support mechanism, when the user takes the circuit board main body, first, the operator holds or pinches the first support piece, the second support piece and the third support piece to avoid direct contact with the circuit board main body.

[0030] The following will describe the embodiments of the present utility model according to its overall structure.

[0031] Embodiment 1:

[0032] A PCB circuit board with blind vias, as Figures 1 - 4 shown, includes a circuit board main body 1. Support mechanisms 2 are provided on both sides of the circuit board main body 1. The support mechanism 2 includes a first support piece 201, a second support piece 202, and a third support piece 203. The first support piece 201, the second support piece 202, and the third support piece 203 are fixedly connected to the insulating layer inside the circuit board main body 1 through a connecting piece 204. When the user performs a taking operation on the circuit board main body 1, the user can hold or pinch the first support piece 201, the second support piece 202, and the third support piece 203 to avoid directly contacting the circuit board main body. This method effectively prevents damage or contamination that may be caused by direct contact. At the same time, the support mechanism 2 is made of epoxy resin material, which has excellent insulation performance and can effectively prevent the static electricity of the human body from being conducted to the circuit board main body 1, thereby improving the safety protection of the circuit board, especially enhancing its anti-static performance, protecting the circuit board and ensuring the safety of the operation process.

[0033] Refer to Figure 3 、 Figure 4, the first support piece 201, the second support piece 202, and the third support piece 203 are in a strip structure, which is used to provide the acting force points of the user on the circuit board main body 1. The strip structure enables the user to hold or pinch conveniently, providing clear and stable acting force points for the user. Such a structure helps the user to control and operate the circuit board main body 1 more precisely when taking, moving, or performing other operations. At the same time, the setting of the strip structure also increases the contact area and disperses the acting force, thereby reducing the damage that may be caused to the circuit board due to excessive local pressure. It not only facilitates the user's operation but also protects the circuit board main body 1 from damage to a certain extent.

[0034] Refer to Figure 1 , Figure 2 , multiple sets of connecting pieces 204 are provided and arranged in an equidistant linear pattern along the length line of the first support piece 201, enhancing the connection stability between the support piece and the circuit board main body 1. The multiple sets of connecting pieces 204 are evenly distributed, which can effectively disperse the pressure and tension received by the support piece, improving the load-bearing capacity of the overall structure. At the same time, the equidistant linear arrangement of the connecting pieces also ensures the uniform transmission of force, avoiding the stress concentration phenomenon, thereby extending the service life of the circuit board. This layout also makes the support mechanism more beautiful and tidy, enhancing the overall texture and reliability of the product.

[0035] Refer to Figure 3 , Figure 4 , a plurality of friction pieces 205 are provided on the top surface of the first support piece 201 and arranged in an equidistant linear pattern along the width line of the first support piece 201. The plurality of friction pieces 205 increase the friction force between the user and the support piece, making the grip more stable and reducing the risk of slipping or dropping the hand during the operation. At the same time, the friction pieces 205 are arranged in an equidistant linear pattern along the width line of the first support piece 201, ensuring the uniform distribution of the friction force and further enhancing the stability and comfort of the grip. It not only enhances the user's operation experience but also improves the safety of the operation process.

[0036] Refer to Figure 3 , Figure 4 , the material of the friction piece 205 is a rubber strip, and the materials of the first support piece 201, the second support piece 202, and the third support piece 203 are all epoxy resin. The rubber strip material has good elasticity and friction, which can provide sufficient friction force to ensure that the user's hand does not slip when holding the support piece, thereby increasing the stability and safety of the operation. At the same time, epoxy resin has excellent insulation performance and mechanical strength, which can effectively prevent damage to the circuit board main body 1 caused by static electricity, and the support piece is not easily deformed or damaged, thus ensuring the stability and durability of the support mechanism.

[0037] Embodiment Two:

[0038] Refer to Figure 3 、 Figure 4 At the connection between the connecting piece 204 and the circuit board main body 1, a plurality of breakable holes 206 are provided. These breakable holes 206 enable the user to easily remove the support mechanism 2 from the circuit board main body 1 when needed. The setting of the breakable holes 206 reduces the difficulty during the removal process and improves the operation convenience. At the same time, the breakable holes 206 also allow the user to selectively remove some or all of the support pieces according to needs to meet different usage requirements, providing greater flexibility and enabling the circuit board main body 1 to be used more conveniently and efficiently in different application scenarios.

[0039] Refer to Figure 1 、 Figure 2 On the surface of the circuit board main body 1, blind holes 3 and mounting holes 4 are provided. The provision of the blind holes 3 helps to optimize the circuit layout, improve the overall performance and reliability of the circuit board. The setting of the blind holes 3 enables the circuit board to achieve more complex circuit connections within a limited space, while reducing the wiring difficulty and cost. At the same time, the provision of the mounting holes 4 facilitates the installation and fixation of the circuit board. Through the mounting holes 4, the circuit board can be stably installed in the device or chassis, ensuring the stability and safety of the circuit board, meeting both the functional requirements of the circuit board and improving its practicality and convenience.

[0040] The implementation principle of the present utility model is as follows: When the user performs the operation of taking the circuit board main body 1, first, the operator can hold or pinch the first support piece 201, the second support piece 202, and the third support piece 203 to avoid the user's direct contact with the circuit board main body 1, and the material of the support mechanism 2 is set as epoxy resin, which is beneficial to providing good insulation performance and preventing the static electricity of the human body from being conducted to the circuit board main body 1, thereby enhancing the safety protection of the circuit board main body 1 and further improving its anti-static performance. Subsequently, through the mounting holes 4, bolts are used for installation operation with the external mounting points to complete the installation operation of the circuit board main body 1. Then, the first support piece 201, the second support piece 202, and the third support piece 203 can be removed through the breakable holes 206 to avoid the influence of the existence of the support mechanism 2 on the use of the circuit board main body 1;
