Description

Technical Field

[0001] The utility model relates to the technical field of display device packaging, and in particular to a packaging substrate and a packaging system. Background Art

[0002] At present, the pixel pitch of display devices is getting smaller and smaller, which means that the size of display units needs to be made smaller and smaller. This is accompanied by the requirement for thinner packaging substrates. When the packaging substrate is thin to a certain extent, the strength of the packaging substrate will be significantly reduced, and the board will bend and warp more, making it impossible to directly automate the operation.

[0003] In the related art, the following two methods are used to solve the above problems: the first is to use a carrier plate + cover plate combination to clamp the packaging substrate between the carrier plate and the cover plate, so as to ensure the flatness of the packaging substrate; the second is to directly use double-sided tape to bond the packaging substrate and the carrier plate together.

[0004] However, the following problems exist in the first method: 1. The action of placing the package substrate into the carrier is relatively complicated, and it is difficult to realize automation; 2. Because of the existence of the cover plate, the upper surface of the cover plate will be higher than the functional area of ​​the package substrate, which will affect the subsequent operations. For example, when printing, the area near the cover plate and the middle area of ​​the functional area will have inconsistent tin amounts. The inventors learned through practice that there is more tin near the cover plate, and the chip in this area is easy to shift, affecting the display effect; 3. In order to avoid inconsistent tin amounts, the cover plate is usually made very thin to reduce the impact of inconsistent tin points, but this will cause large loss of the cover plate. The following problems exist in the second method: 1. It is difficult to paste the board, and a carrier plate and double-sided tape are required, and there are no bubbles between the double-sided tape and the package substrate; 2. The double-sided tape is easy to delaminate after multiple high-temperature processes; 3. After the double-sided tape is pasted on the package substrate and has undergone multiple high-temperature processes or pressurization processes, it is not easy to separate, and it is easy to stick to the surface of the package substrate; 4. Double-sided tape is mostly disposable and has a high replacement frequency.

[0005] Therefore, there is a problem in the related art that it is not easy to realize automated production. Utility Model Content

[0008] Furthermore, the substrate body has a functional area, and the magnetic ink layer and the functional area are staggered in the extension direction of the substrate body.

[0012] Furthermore, the substrate body is a rectangular structure, the magnetic ink layer includes a plurality of side edges connected to each other, and the widths of the plurality of side edges are all equal.

[0018] The drawings constituting part of the present application are used to provide a further understanding of the present invention. The exemplary embodiments of the present invention and their descriptions are used to explain the present invention and do not constitute an improper limitation on the present invention. In the drawings:

[0019] Figure 1 A schematic structural diagram of a packaging system provided by an embodiment of the utility model is shown.

[0020] The above drawings include the following reference numerals:

[0021] 10. Base plate body; 11. Functional area;

[0022] 20. Magnetic ink layer; 21. Side edge;

[0023] 30. carrier plate; 31. magnetic part;

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] like Figure 1 As shown, an embodiment of the utility model provides a packaging substrate, which includes a substrate body 10 and a magnetic ink layer 20, the magnetic ink layer 20 is arranged on the surface of the substrate body 10, and the carrier 30 is provided with a magnetic part 31, and the magnetic ink layer 20 can be magnetically matched with the magnetic part 31.

[0027] The packaging substrate provided in this embodiment is used to solve the difficulty of assembly and separation, and to facilitate automation and ensure the process effect. When designing the packaging substrate, a magnetic ink area is designed, and the carrier only needs to be equipped with a magnet. Specifically, when the packaging substrate and the carrier 30 are assembled together, the magnetic attraction of the magnetic part 31 and the magnetic ink layer 20 can be used to fix the packaging substrate and the carrier 30, so that the packaging substrate and the carrier 30 are convenient to fit. When it is necessary to separate the packaging substrate from the carrier 30, due to the magnetic attraction between the packaging substrate and the carrier 30, it is only necessary to remove the packaging substrate with force, which is convenient for unloading. Therefore, the above structure can achieve easy fitting of the packaging substrate and the carrier 30, convenient unloading, and convenient automated production.

[0028] Furthermore, the structure of this embodiment can overcome the problem of inconsistent tin amount in the related art. Specifically, in the related art, due to the presence of the cover plate, the upper surface of the cover plate will be higher than the functional area of ​​the package substrate, which will affect subsequent operations. For example, when printing, the area near the cover plate and the middle area of ​​the functional area will have inconsistent tin amounts. The inventors have learned through practice that there is more tin near the cover plate, and the chip in this area is easy to shift, affecting the display effect. In this embodiment, since there is no need to set a cover plate, the problem of inconsistent tin amount can be overcome.

[0029] It should be noted that the package substrate and the carrier 30 are fixed by the magnetic attraction cooperation between the magnetic part 31 and the magnetic ink layer 20 . It is only necessary to provide the magnetic ink layer 20 on the package substrate, and there is no pollution to the package substrate.

[0030] In addition, the magnetic attraction method has the advantages of being reusable and having low loss.

[0031] like Figure 1 As shown, in this embodiment, the substrate body 10 has a functional area 11, and the magnetic ink layer 20 and the functional area 11 are staggered in the extension direction of the substrate body 10. With the above structure, the magnetic ink layer 20 and the functional area 11 do not interfere with each other.

[0032] like Figure 1 As shown, in this embodiment, the magnetic ink layer 20 is arranged at the edge of the substrate body 10. When the magnetic portion 31 and the magnetic ink layer 20 are magnetically matched, since the magnetic ink layer 20 is arranged at the edge of the substrate body 10, it is equivalent to the edge of the substrate body 10 being magnetically matched with the carrier 30, the substrate body 10 is not easy to shake, which can improve the assembly firmness of the package substrate.

[0033] In this embodiment, the magnetic ink layer 20 is an annular structure extending along the circumference of the substrate body 10. When the magnetic portion 31 and the magnetic ink layer 20 are magnetically matched, the entire outer edge of the substrate body 10 can be magnetically matched with the carrier 30, thereby further improving the assembly firmness of the package substrate.

[0034] It should be noted that the magnetic ink layer 20 is an annular structure extending along the circumference of the substrate body 10 , and the “annular structure” here means that the magnetic ink layer 20 is a closed loop structure. The shape of the magnetic ink layer 20 is adapted to the outer shape of the substrate body 10 .

[0035] In other embodiments, the magnetic ink layer 20 includes a plurality of magnetic ink segments, and the plurality of magnetic ink segments are arranged at intervals along the circumference of the substrate body 10. The plurality of magnetic ink segments are magnetically matched with the magnetic portion 31 to achieve magnetic matching between the magnetic portion 31 and the magnetic ink layer 20. Specifically, the plurality of magnetic ink segments are arranged at equal intervals along the circumference of the substrate body 10 to improve assembly stability.

[0036] In this embodiment, the substrate body 10 is a rectangular structure, and the magnetic ink layer 20 also forms a rectangular ring structure.

[0037] like Figure 1 As shown, in this embodiment, the outer edge of the magnetic ink layer 20 is flush with the outer edge of the substrate body 10. With the above structure, the outer edge of the magnetic ink layer 20 is placed outward as much as possible, thereby improving the assembly firmness of the package substrate.

[0038] The magnetic ink layer 20 includes a plurality of connected side edges 21, and the widths of the plurality of side edges 21 are all equal. When the magnetic portion 31 and the magnetic ink layer 20 are magnetically attracted to each other, the magnetic attraction force of each side edge 21 of the magnetic ink layer 20 is equal to that of the magnetic ink layer 20, which can improve the assembly stability of the package substrate.

[0039] In this embodiment, the substrate body 10 is a rectangular structure, and the magnetic ink layer 20 includes four connecting side edges 21 , and the widths of the four connecting side edges 21 are all equal.

[0040] In other embodiments, if the shape of the substrate body 10 changes, the shape of the magnetic ink layer 20 is adaptively adjusted, but the width of the magnetic ink layer 20 at each portion in the circumferential direction remains the same.

[0041] It should be noted that the width of the side edge 21 refers to the dimension of the side edge 21 in the direction from the center of the substrate body 10 to the edge.

[0042] like Figure 1 As shown, another embodiment of the utility model provides a packaging system, which includes a carrier 30 and a packaging substrate 40, and the packaging substrate 40 is arranged on the carrier 30, and the packaging substrate 40 is the packaging substrate provided above. Therefore, the packaging system can also realize easy bonding of the packaging substrate and the carrier 30, convenient unloading, and convenient automatic production.

[0043] In this embodiment, the shape of the magnetic part 31 is adapted to the shape of the magnetic ink layer 20, so that the magnetic part 31 and the magnetic ink layer 20 can be magnetically attracted to each other and the adsorption is firm.

[0044] The substrate body 10 is a rectangular structure, the magnetic ink layer 20 is a rectangular ring structure, and the magnetic portion 31 is also a rectangular ring structure.

[0045] In this embodiment, the size of the carrier 30 is larger than that of the packaging substrate 40 , and a magnetic portion 31 is disposed at the edge of the projection of the carrier 30 on the packaging substrate 40 .

[0046] In this embodiment, the magnetic part 31 includes a magnet, which has the advantages of simple structure and low cost.

[0047] Specifically, the magnet is a strong magnet and has the advantage of firm adsorption.

[0048] The device provided by the embodiment has the following beneficial effects:

[0049] (1) When the packaging substrate and the carrier 30 are assembled together, the magnetic attraction of the magnetic part 31 and the magnetic ink layer 20 can be used to fix the packaging substrate and the carrier 30, which is convenient for the packaging substrate and the carrier 30 to fit together. When it is necessary to separate the packaging substrate from the carrier 30, due to the magnetic attraction between the packaging substrate and the carrier 30, it is only necessary to use force to remove the packaging substrate, which is convenient for unloading. Therefore, it is possible to achieve easy fitting of the packaging substrate and the carrier 30, convenient unloading, and convenient automated production;

[0050] (2) In the related art, the existence of the cover plate will make the upper surface of the cover plate higher than the functional area of ​​the package substrate, which will affect the subsequent operation. For example, when printing, the amount of tin in the functional area near the cover plate and the middle area will be inconsistent. The inventors have learned through practice that there is more tin near the cover plate, and the chip in this area is easy to shift, affecting the display effect. In this embodiment, since there is no need to set a cover plate, the problem of inconsistent tin amount can be overcome;

[0051] (3) The package substrate and the carrier 30 are fixed by the magnetic attraction of the magnetic part 31 and the magnetic ink layer 20. It is only necessary to set the magnetic ink layer 20 on the package substrate, and there is no pollution to the package substrate.

[0052] (4) It adopts the magnetic attraction method, which has the advantages of reusability and low loss.

If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.
