Description

Technical Field

[0001] This application relates to the field of circuit boards, for example to a circuit board panel. Background Technology

[0002] Circuit board panelization refers to combining multiple small circuit boards together to facilitate production. Circuit board panelization can help circuit board manufacturers save costs and improve production efficiency.

[0003] Common methods for splicing circuit boards include V-cut, perforated holes, and solid connections. Solid connections refer to connecting the individual circuit boards using connecting ribs.

[0004] However, in the current solid connection panel design, burrs are easily generated at the corners of the circuit boards during the separation process, which requires manual polishing to remove the burrs and reduces the separation efficiency. Utility Model Content

[0005] To overcome the problems existing in the related technologies, this application provides a circuit board panel that can avoid burrs at the corners of the circuit boards during separation, thereby improving separation efficiency.

[0006] According to a first aspect of the embodiments of this application, a circuit board panel is provided, characterized in that it includes a plurality of first connecting components and a plurality of circuit boards arranged in an array; a first channel is provided between adjacent circuit boards in a first direction of array arrangement, and a second channel is provided between adjacent circuit boards in a second direction of array arrangement, wherein the first direction and the second direction are perpendicular to each other.

[0007] Every four circuit boards arranged in a 2x2 array are connected by a first connecting component; the first connecting component includes a first connecting part, a second connecting part, and a third connecting part; the second connecting part is located at the intersection of the first channel and the second channel; the first connecting part and the third connecting part are respectively disposed on both sides of the second connecting part extending along the first direction, and the two sides of the first connecting part and the two sides of the third connecting part are respectively connected to the side of a circuit board; the width of the second connecting part in the second direction is smaller than the width of the first connecting part in the second direction, and the width of the second connecting part in the second direction is smaller than the width of the third connecting part in the second direction;

[0008] The first connecting part is recessed inward at the connection point with the connected circuit board near the second connecting part to form a first arc-shaped structure, and the third connecting part is recessed inward at the connection point with the connected circuit board near the second connecting part to form a second arc-shaped structure.

[0009] This application embodiment optimizes the first connecting component. Specifically, the first connecting component includes a first connecting part, a second connecting part, and a third connecting part. A first arc-shaped structure is formed by recessing the first connecting part near the second connecting part at the connection between the first connecting part and the connected circuit board. A second arc-shaped structure is formed by recessing the third connecting part near the second connecting part at the connection between the third connecting part and the connected circuit board. Since the arc-shaped structure can change the contact angle between the cutting tool and the circuit board, the cutting force is more evenly distributed on the surface of the circuit board. Therefore, burrs can be avoided at the corners of the circuit board during separation, eliminating the need for manual burr removal and improving separation efficiency.

[0010] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application.

[0018] In related technologies, the length of the connecting ribs used in solid-connection panel designs is generally equal to two or three times the distance between the two circuit boards, and the width of the connecting ribs is equal to the distance between the two circuit boards. Using this type of connecting rib, burrs are easily generated at the corners of the circuit boards when using cutting tools to separate them.

[0019] This application embodiment optimizes the structure of the first connecting component. Specifically, the first connecting component includes a first connecting part, a second connecting part, and a third connecting part. A recessed arc-shaped structure is formed on the plane where the first connecting part and the second connecting part contact each other and near the corner of the circuit board. A recessed arc-shaped structure is also formed on the plane where the third connecting part and the second connecting part contact each other and near the corner of the circuit board. Since the arc-shaped structure can change the contact angle between the cutting tool and the circuit board, the cutting force is more evenly distributed on the surface of the circuit board, thereby avoiding burrs at the corner of the circuit board during board separation.

[0020] Please see Figure 1 The circuit board panel provided in this application includes a plurality of first connecting components 1 and a plurality of circuit boards 2 arranged in an array; a first channel 3 is provided between adjacent circuit boards in the first direction of the array arrangement, and a second channel 4 is provided between adjacent circuit boards in the second direction of the array arrangement, wherein the first direction and the second direction are perpendicular to each other.

[0021] Four circuit boards 2 arranged in a 2x2 array are connected by a first connecting component 1. The first connecting component 1 includes a first connecting part 11, a second connecting part 12, and a third connecting part 13. The second connecting part 12 is located at the intersection of the first channel 3 and the second channel 4. The first connecting part 11 and the third connecting part 13 are respectively disposed on both sides of the second connecting part 12 extending along the first direction, and the two sides of the first connecting part 11 and the two sides of the third connecting part 13 are respectively connected to the side of a circuit board. The width of the second connecting part 12 in the second direction is smaller than the width of the first connecting part 11 in the second direction, and the width of the second connecting part 12 in the second direction is smaller than the width of the third connecting part 13 in the second direction.

[0022] The first connecting part 11 is recessed at the connection point with the connected circuit board 2 near the second connecting part 12 to form a first arc-shaped structure 111, and the third connecting part 13 is recessed at the connection point with the connected circuit board 2 near the second connecting part 12 to form a second arc-shaped structure 131.

[0023] The first connecting component is a connecting rib, with a first direction being horizontal and a second direction being vertical. Alternatively, the first direction is vertical and the second direction is horizontal.

[0024] The circuit board is square or rectangular, and the side of the circuit board is the plane containing the right-angled side of the circuit board.

[0025] In this embodiment, the first direction is vertical and the second direction is horizontal, as an example. Specifically, the left and right sides of the first connecting part 11 are connected to the side of a circuit board, thereby splicing two circuit boards in the horizontal direction. The left and right sides of the third connecting part 13 are connected to the side of a circuit board, thereby splicing two other circuit boards in the horizontal direction. The second connecting part 12 connects the first connecting part 11 and the third connecting part 13, thereby splicing four circuit boards arranged in a 2*2 array.

[0026] At the junction of the first connecting portion 11 and the second connecting portion 12, near the connected circuit board, a concave first arc-shaped structure 111 can be formed by drilling or punching holes. At the junction of the third connecting portion 13 and the second connecting portion 12, near the connected circuit board, a concave second arc-shaped structure 131 can be formed by drilling or punching holes.

[0027] This application embodiment optimizes the first connecting component. Specifically, the first connecting component includes a first connecting part 11, a second connecting part 12, and a third connecting part 13. A first arc-shaped structure 111 is formed inward at the connection between the first connecting part 11 and the connected circuit board 2 near the position of the second connecting part 12. A second arc-shaped structure 131 is formed inward at the connection between the third connecting part 13 and the connected circuit board 2 near the position of the second connecting part 12. Since the arc-shaped structure can change the contact angle between the cutting tool and the circuit board, the cutting force is more evenly distributed on the surface of the circuit board. Therefore, when separating the boards, burrs can be avoided at the corners of the circuit board, eliminating the need for manual burr removal and improving the separation efficiency.

[0028] In one embodiment, the first arc structure 111 and the second arc structure 131 are the same size and are both axially symmetrical about the center line of the second channel in the first direction.

[0029] In this embodiment, both the first arc-shaped structure 111 and the second arc-shaped structure 131 are axisymmetric structures, which can evenly distribute pressure, reduce stress concentration, and improve stability.

[0030] In one embodiment, both the first arc structure 111 and the second arc structure 131 are semicircular arcs.

[0031] In this embodiment of the application, both the first arc structure 111 and the second arc structure 131 are designed as semi-circular arcs, which can ensure axial symmetry and avoid the generation of burrs during plate separation.

[0032] In one embodiment, the diameter of the semicircular arc is half the difference between the width of the first connecting portion 11 in the second direction and the width of the second connecting portion 12 in the second direction.

[0033] In this embodiment, the diameter of the semicircular arc is designed to be half the difference between the width of the first connecting part 11 in the second direction and the width of the second connecting part 12 in the second direction. This maximizes the arc length, thereby maximizing the change in the contact angle between the cutting tool and the circuit board during board separation and avoiding burr generation.

[0034] In one embodiment, the width of the first connecting portion 11 in the second direction is 1.4-1.6 mm, and the width of the second connecting portion 12 in the second direction is 0.6-0.8 mm.

[0035] In this embodiment, the width of the first connecting portion 11 in the second direction can be 1.5 mm, and the width of the second connecting portion 12 in the second direction can be 0.7 mm. By setting the above width values, the splicing strength of the circuit board can be ensured to meet the requirements.

[0036] In one embodiment, the diameter of the semicircular arc is 0.3-0.5 mm.

[0037] In this embodiment, the diameter of the semicircular arc can be 0.4 mm. By setting the above diameter value, the arc length can be maximized while ensuring that the splicing strength of the circuit board meets the requirements. This allows for a greater variation in the contact angle between the cutting tool and the circuit board during board separation, thus avoiding the generation of burrs.

[0038] In one embodiment, the width of the second connecting portion 12 in the first direction is the spacing between adjacent circuit boards in the first direction of the array arrangement.

[0039] In this embodiment, the spacing between adjacent circuit boards in the first direction of the array arrangement is the width of the first channel. Designing the width of the second connecting part 12 in the first direction to be the width of the first channel ensures that the side of the first connecting part 11 and the side of the third connecting part 13 are flush with the side of the circuit board at the board separation position, which helps to avoid burrs during subsequent board separation.

[0040] In one embodiment, the side of the first connecting portion 11 away from the second connecting portion 12 is a concave arc structure, and the side of the third connecting portion 13 away from the second connecting portion 12 is a concave arc structure.

[0041] Among them, the concave arc structure can be an axisymmetric arc structure.

[0042] In this embodiment, the concave arc structure is a semi-circular arc. This structural design helps prevent burrs from forming during plate separation.

[0043] In one embodiment, the circuit board panel further includes a plurality of second connecting components, wherein two adjacent circuit boards located at the boundary of the circuit board panel are connected by a second connecting component.

[0044] The second connecting component is a connecting rib.

[0045] In this embodiment of the application, the left and right sides of the second connecting component are connected to two adjacent circuit boards located at the boundary of the circuit board panel, thereby splicing the two adjacent circuit boards located at the boundary of the circuit board panel.

[0046] In one embodiment, the two ends of the second connecting component along the first direction are concave arc structures.

[0047] Among them, the concave arc structure can be an axisymmetric arc structure.

[0048] In this embodiment, the concave arc structure is a semi-circular arc. By making both ends of the second connecting component along the first direction semi-circular arcs, burrs can be avoided during plate separation.

[0049] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0050] The above are merely embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
