However, because the mold release is a coating of chemical material, components on the pre-protective surface of the semi-finished product can be contaminated to varying degrees. Furthermore, in the case of a highly integrated module, the pre-protection surface of the semi-product has different material modules, and the different material modules will have different adsorption degrees to the auxiliary film, which will cause damage to the module when the auxiliary film is removed.

Detailed Description
For a further understanding and appreciation of the features and advantages achieved by the present invention, the following description will be presented in terms of examples and accompanying drawings:
in view of the above-mentioned problems of the prior art, the present invention provides an auxiliary film comprising a body and a plurality of microstructures. The microstructure is formed on the first surface of the body to form an uneven surface, and two ends of the microstructure extend to the periphery of the first surface respectively. When the first surface of the body is attached to a pre-protection surface of a substrate, the microstructure forms an open gas flow channel. The open gas flow channel is utilized to increase the separation efficiency of the auxiliary film and the substrate, so as to correspondingly increase the operation speed of the process and further reduce the overall process time.
Hereinafter, various examples will be described with respect to the auxiliary film structure of the present invention.
Referring to fig. 1, which is a schematic structural diagram of an embodiment of the present invention, as shown in the drawing, the embodiment is an auxiliary film 1 attached to a pre-protecting surface 4 of a substrate 2, so that the auxiliary film 1 and the substrate 2 are attached to each other, and the auxiliary film 1 includes a body 10; in the present embodiment, the material of the body 10 is a polymer material, such as Polyethylene (PE), polyethylene terephthalate (PET), polycarbonate (PC), polyimide (PI), polyvinyl chloride (PVC), polystyrene (PS), polymethyl methacrylate (PMMA), but the present embodiment is not limited thereto.
Referring to fig. 1 and 2A, fig. 2A is an enlarged schematic view of the structure of an embodiment of the present invention, which is an enlarged schematic view of fig. 1, as shown in the drawings, in this embodiment, the body 10 is provided with a plurality of microstructures 14 (e.g. a plurality of slots) on a first surface 12 contacting the pre-protection surface 4 of the substrate 2, so as to form a concave-convex surface, and two ends of the microstructures 14 respectively extend to the periphery of the first surface 12. In this embodiment, one end of the microstructure 14 extends to a first outer edge 122 of the first surface 12, and the other end extends to a second outer edge 124 of the first surface 12, that is, the microstructure 14 extends from the first outer edge 122 and the second outer edge 124 to the inner side of the first surface 12, and the first outer edge 122 and the second outer edge 124 are the peripheries of the first surface 12. As shown in the drawing, when the auxiliary film 1 is disposed on the pre-protection surface 4 of the substrate 2, the substrate 2 is abutted against the respective microstructures 14, so that the substrate 2 and the respective microstructures 14 form a plurality of open gas flow channels 142, i.e. a plurality of open gas flow channels 142 are formed between the substrate 2 and the first surface 12 of the body 10.
Referring to fig. 1, fig. 2A, and fig. 2B together, fig. 2B is a schematic cross-sectional view of an embodiment of the present invention, as shown in the drawings, in this embodiment, at least one component 3, such as an electronic component or a component formed by a chemical material coating, is disposed on a pre-protecting end surface of the substrate 2, and the component 3 is correspondingly abutted against the first surface 12 of the body 10. Similarly, the assembly 3 will abut the microstructure 14 and form the open gas flow channel 142. In this embodiment, the component 3 may be a battery module, a chip, or a bio-sensing material coating or a silicone coating. When the component 3 is an electronic component such as a battery module, a chip, or the like, the substrate 2 may be a circuit board, particularly a flexible circuit board.
In this embodiment, a plurality of grooves are formed on the first surface 12 of the microstructure 14, so that the substrate 2 and the microstructures 14 form the open gas flow channel 142.
In this embodiment, the microstructures 14 have a V-shaped structure for guiding a fluid, such as air, into the open gas channels 142 of the respective microstructures 14. In addition, in the present embodiment, the distance between the microstructures 14 may be appropriately adjusted according to the material characteristics of the components 3 disposed on the substrate 2 and the pre-protection surface 4 and the process station requirements, such as the required adhesion capability between the auxiliary film and the substrate at the process station.
Referring to fig. 1 to 2C, fig. 2C is a schematic diagram illustrating separation of the auxiliary membrane and the substrate according to the present invention, in this embodiment, a fluid a flows to the inner side of the open gas flow channel 142 through the openings of the microstructure 14 at the periphery, and the open gas flow channel 142 has open openings with two ends communicating with each other, so that the fluid a can enter and exit the non-blocking flowing state. When the substrate 2 is separated from the auxiliary film 1, the flowable gas can effectively avoid the vacuum-like adsorption effect of the non-flowable gas between the substrate and the auxiliary film due to the lamination process, except that the microstructure reduces the total amount of the unit area of the substrate 2 contacted with the auxiliary film 1. The auxiliary film of the invention can increase the separation efficiency from the base material 2, so that the base material 2 can still be normally separated from the body 10 when the base material 2 is fed at a high speed, the components 3 of the base material 2 are not affected, and the production time of a corresponding production line is further reduced. Furthermore, when the first surface 12 of the auxiliary film 1 of the present invention is coated with the release agent, the amount of the release agent contacting the substrate 2 and the component 3 can be reduced under the structural design of the present invention, so as to reduce the pollution degree of the release agent to the substrate 2 and/or the component 3.
Referring to fig. 3 and fig. 4, fig. 3 is a schematic structural diagram of another embodiment of the present invention, and fig. 4 is a schematic structural sectional diagram of another embodiment of the present invention, which is a schematic structural sectional diagram of fig. 3. As shown, in the present embodiment, the microstructure 14 may have a U-shaped structure.
Referring to fig. 6, a schematic microstructure diagram of another embodiment of the present invention is shown, in this embodiment, besides the microstructure on the first surface is substantially identical in shape, the microstructures may also be designed in different shapes or with a non-constant distance between two adjacent microstructures to form a dense design. For example, as shown in fig. 5, fig. 5 is a schematic microstructure of another embodiment of the present invention. In this embodiment, the microstructures 14 take on irregular, distinct shapes.
The preferred arithmetic average roughness (Arithmetic average roughness) of the relief surface resulting from the microstructure 14 is between 0.1 microns and 0.5 microns for better separation efficiency in the present invention, but those skilled in the art should appreciate that the scope of the present invention is not limited thereto.
Referring to fig. 7, which is a schematic diagram illustrating the application of the structure of an embodiment of the present invention, the auxiliary film 1 of the present invention can also be applied to the battery industry of roll-to-roll mass production, such as a sheet lithium battery. In this state, for example, the substrate 2 may be a flexible metal substrate serving as a current collecting layer, and a component of a different material is provided on the protective surface of the pre-attached auxiliary film. The heterogeneous component comprises, for example, an active material coating 5 and a frame layer 6 surrounding the active material coating. The material of the frame layer 6 may be silica gel. The different material components will generate different adsorption forces to the auxiliary membrane 1, which will make the traditional auxiliary membrane have poor effect in separation, and the auxiliary membrane of the invention can effectively solve the problem due to the open gas flow passage.
In summary, the present invention provides an auxiliary film, which includes a main body and a plurality of microstructures disposed on a first surface of the main body to form an uneven surface, wherein two ends of the microstructures extend to a periphery of the first surface. When the first surface of the body is attached to a pre-protection surface of a substrate, the microstructure forms an open gas flow channel. The open gas flow channel can reduce the adsorption force between the auxiliary film and the substrate, increase the separation efficiency of the auxiliary film and the substrate, improve the operation speed of the process, further reduce the whole process time, and solve the problems of the prior art that the separation property of the release film is insufficient, the release film is easy to adhere to the electronic component arranged on the substrate, the component is damaged or polluted due to adsorption and tearing, and the like, the process yield is reduced, and the additional cost is generated.
The foregoing description is only one embodiment of the present invention and is not intended to limit the scope of the present invention, so that all changes and modifications in shape, construction, characteristics and spirit of the present invention as defined in the appended claims should be construed as included in the scope of the present invention.
