Description

Technical Field

[0001] The utility model relates to the technical field of circuit boards, in particular to a circuit board with embedded components. Background Art

[0002] Embedded component circuit boards, also known as embedded component PCBs, are specially designed circuit boards that utilize embedded technology to mount components (such as resistors, capacitors, and chips) within the PCB's internal layers, rather than traditional surface-mount or through-hole mounting methods. This technology effectively optimizes board space utilization, improves electrical performance, and, in some applications, enables smaller, higher-density designs. Generally speaking, embedded component PCBs are a highly integrated, high-performance circuit board technology widely used in applications with strict requirements on space, volume, electrical performance, and thermal management. Although their design and manufacturing are challenging, the increasing miniaturization and integration of electronic products suggests that embedded component technology will have broader application prospects.

[0003] Currently, existing circuit boards with embedded components are prone to heat generation during use. Due to the embedded design, the generated heat cannot be discharged, which can easily cause the circuit boards to burn out. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a circuit board with embedded components, which has the advantages of improving the heat dissipation effect of the components embedded in the circuit board and increasing the service life of the circuit board. It solves the problem that the heat generated by the circuit board with embedded components during operation cannot be effectively removed, which easily causes the circuit board to burn.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a circuit board with embedded components, comprising an insert plate, a film body, a rubber plate and an outer circuit board, the top and bottom surfaces of the insert plate are sequentially installed with a film body, a rubber plate and an outer circuit board, the film body has elastic force, and is used to provide support for the insert plate and the insert embedded inside, thereby improving the overall toughness of the circuit board, and the film body is hollowed out at the position of the insert and does not cover the insert, and the rubber plate is a thermally conductive silicone, which covers the insert and provides heat dissipation and cooling for the insert.

[0006] The insert plate is provided with insert grooves in which components are clamped. The number of the insert grooves provided on the insert plate is the same as the number of embedded components, and the size of the insert grooves matches the size of the embedded components.

[0007] The edges of the outer circuit board are bonded with protective edge strips, which are covered on the sides of the insert plate, membrane body and rubber plate. The protective edge strips are made of rubber and are hollow inside. Air enters the protective edge strips to cool the rubber plate, thereby achieving heat dissipation and cooling treatment for the covered insert.

[0008] During installation and operation of the circuit board with embedded components, the components are embedded in the embedding grooves provided on the embedding plate, and then the membrane, rubber plate and outer circuit board are installed outward in sequence on the top and bottom surfaces of the embedding plate, and then copper welding parts are set in the installation holes and fixed by welding technology, and a circle of protective edge strips are bonded to the side edges of the outer circuit board. Air enters the protective edge strips to dissipate heat and cool the rubber plate, and after the rubber plate cools down, the covered components can be cooled.

[0009] As a further improvement of the above solution, a docking port is provided on a side of the outer circuit board close to the insert plate, and the docking port is covered on the side of the component.

[0010] Through the above technical solution, the docking port corresponds to the position of the component embedded in the insert plate, and when the outer circuit board and the insert plate are installed, the docking port covers the side of the corresponding component.

[0011] As a further improvement of the above solution, a convex strip is fixed to the edge of the docking port, and the convex strip fits on the inner side of the insert groove.

[0012] With the above technical solution, the inner side of the convex strip is inclined outward. When the outer circuit board and the insert plate are closed, the convex strip presses the film body at the upper edge of the component to prevent the film body from moving.

[0013] As a further improvement of the above solution, the edges of the opposing surfaces of the outer circuit board and the insert plate are both provided with teeth, and the teeth are meshed with each other.

[0014] Through the above technical solution, when the outer circuit board and the insert plate are closed and installed, the teeth are engaged with each other, thereby improving the installation stability between the outer circuit board and the insert plate.

[0015] As a further improvement of the above solution, corresponding positions on the outer circuit board, the rubber plate, the membrane body and the insert plate are all provided with mounting holes, and copper welding parts are installed in the mounting holes.

[0016] Through the above technical solution, the copper welding parts are installed in the mounting holes of each layer of the board body, so that each layer of the board body is aligned and welded to the outer circuit board through the copper welding parts.

[0017] As a further improvement of the above solution, a through hole is provided on the protective edge strip, and the through hole passes through the interior of the protective edge strip.

[0018] Through the above technical solution, the through holes are used to input air into the protective edge strips, thereby improving the cooling efficiency of the rubber plate, thereby ensuring the speed of heat dissipation and cooling of the components.

[0019] Compared with the prior art, the present invention provides a circuit board with embedded components, which has the following beneficial effects:

[0020] 1. The circuit board with embedded components has plastic sheets mounted on the upper and lower sides of the insert board, and protective edge strips are installed on the edges of the circuit board. The interior of the protective edge strips is hollow, and gas enters the protective edge strips to cool the rubber sheet. The heat generated by the components covered by the rubber sheet is absorbed and cooled, thereby effectively improving the heat dissipation effect of the components and thus increasing the overall service life of the circuit board.

[0021] 2. The circuit board with embedded components is equipped with protective edge strips on the edge of the circuit board. The protective edge strips provide protection for the edges of the insert board, film body, rubber plate and outer circuit board. When a collision occurs, the protective edge strips squeeze the internal air, and the internal air is suddenly squeezed by the force, which is buffered, thereby effectively preventing damage to the circuit board.

Example 1

[0035] See also Figure 1-Figure 5 As shown, the circuit board with embedded components proposed in this embodiment includes an insert plate 1, a film body 2, a rubber plate 3 and an outer circuit board 4. The top and bottom surfaces of the insert plate 1 are installed with the film body 2, the rubber plate 3 and the outer circuit board 4 in sequence. The film body 2 has elastic force, which is used to provide support for the insert plate 1 and the insert embedded inside, thereby improving the overall toughness of the circuit board. The film body is hollow at the position of the insert and does not cover the insert. The rubber plate 3 is a thermally conductive silicone that covers the insert to provide heat dissipation and cooling for the insert.

[0036] The insert plate 1 is provided with an insert groove 101 , in which the component 5 is clamped. The number of the insert grooves 101 provided on the insert plate 1 is the same as the number of the embedded components 5 (the inserts mentioned above), and the size of the insert groove 101 matches the size of the embedded components 5 .

[0037] The edge of the outer circuit board 4 is bonded with a protective edge strip 6, which is covered on the side of the insert plate 1, the membrane 2 and the rubber plate 3. The protective edge strip 6 is made of rubber and is hollow inside. Air enters the protective edge strip 6 and cools the rubber plate 3, thereby achieving heat dissipation and cooling of the covered insert.

[0038] The working principle of the circuit board with embedded components proposed in this embodiment is as follows: when in use, the component 5 is embedded in the embedding groove 101 opened in the embedding plate 1, and then the film body 2, the rubber plate 3 and the outer circuit board 4 are installed outward on the top and bottom surfaces of the embedding plate 1 in sequence, and then the copper welding part 406 is set in the mounting hole 405 opened and fixed by welding technology, and a circle of protective edge strips 6 are adhered to the side edge of the outer circuit board 4. Air enters the protective edge strips 6 to dissipate heat and cool the rubber plate 3. After the rubber plate 3 cools down, the covered component 5 can be cooled. Example 2

[0040] In this solution, the docking port 401 corresponds to the position of the component 5 embedded in the insert plate 1. When the outer circuit board 4 and the insert plate 1 are installed, the docking port 401 is covered on the side of the corresponding component 5, and the inner side of the ridge 402 is inclined outward. When the outer circuit board 4 and the insert plate 1 are closed, the ridge 402 presses the film body 2 at the upper edge of the component to prevent the film body 2 from moving. When the outer circuit board 4 and the insert plate 1 are closed and installed, the tooth pattern 403 is engaged to improve the installation stability between the outer circuit board 4 and the insert plate 1. The copper welding part 406 is installed in the mounting hole 405 of each layer of the board body so that each layer of the board body is aligned and welded to the outer circuit board 4 through the copper welding part 406. The through hole 601 is used to input air into the protective edge strip 6 to improve the cooling efficiency of the rubber plate 3, thereby ensuring the speed of heat dissipation and cooling of the component 5.
