Description

Technical Field

[0001] This invention relates to the field of flexible circuit board production equipment technology, and particularly to an FPC single-sided double-contact hollow finger production system. Background Technology

[0002] FPC refers to flexible printed circuit boards. When manufacturing patterns for single-sided double-contact cutout fingers on pure copper FPCs, dry film filling and cover film opening are often used. However, after the cover film is bonded to the copper plate, a 20-50µm height difference step is formed in the open area. Therefore, during the dry film filling and cover film opening process, a certain proportion of air bubbles are unavoidable due to the presence of these step areas, leading to circuit defects during etching and causing the product to fail to meet functional requirements and be scrapped. Based on this, this application provides a single-sided double-contact cutout finger manufacturing system for FPCs. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an FPC single-sided double-contact hollow finger production system, comprising:

[0004] A window opening mechanism for creating windows in the cover film of the FPC;

[0005] The screen printing mechanism, connected to the window opening mechanism, is used to screen print an anti-etch ink layer on the window opening area of ​​the FPC cover film;

[0006] The film application mechanism, connected to the screen printing mechanism, is used to apply photosensitive dry film onto the FPC;

[0007] The exposure mechanism, connected to the film application mechanism, is used to expose the FPC so that the desired circuit pattern can be transferred onto the FPC;

[0008] The developing mechanism, connected to the exposure mechanism, is used to develop the circuit patterns on the FPC;

[0009] The etching mechanism, connected to the developing mechanism, is used to etch the FPC to remove the unmasked copper foil on the FPC;

[0010] The film removal mechanism, connected to the etching mechanism, is used to remove the photosensitive dry film and the anti-etching ink layer from the FPC.

[0011] In some embodiments, a pressing mechanism is also included, disposed between the window opening mechanism and the screen printing mechanism, the pressing mechanism being used to press the cover film attached to the FPC.

[0012] In some implementations, the height of the etch-resistant ink layer in the windowed area of ​​the FPC is flush with the height of the cover film of the FPC.

[0013] In some embodiments, the window opening mechanism is connected to the screen printing mechanism, the screen printing mechanism to the film application mechanism, the film application mechanism to the exposure mechanism, the exposure mechanism to the developing mechanism, the developing mechanism to the etching mechanism, and the etching mechanism to the film removal mechanism via conveyor belts.

[0014] In some embodiments, the window opening mechanism is a laser engraving machine, the screen printing mechanism is a screen printing machine, the film application mechanism is a film application machine, the exposure mechanism is an exposure machine, the developing mechanism is a developing machine, the etching mechanism is an etching machine, and the film removal mechanism is a film removal machine.

[0015] In some embodiments, the window opening mechanism is connected to the pressing mechanism and the screen printing mechanism via conveyor belts.

[0016] In some embodiments, the pressing mechanism is a pressing machine.

[0017] Compared with existing technologies, the FPC single-sided double-contact cutout finger production system provided in this application adds a screen printing mechanism between the windowing mechanism and the film-applying mechanism. This screen printing mechanism fills the FPC windowed area with an anti-etching ink layer, ensuring that the windowed area of ​​the FPC cover film is on the same horizontal plane as other areas. This prevents the formation of height differences or steps in the FPC windowed area due to the film opening. Therefore, the FPC products produced by the system provided in this application do not have film bubbles in the FPC windowed area, effectively protecting the copper surface of the FPC, ensuring the integrity of the copper surface, and significantly reducing the scrap rate of FPC products.

[0020] To facilitate understanding of the structure and operation of this utility model, the following description, in conjunction with the accompanying drawings and optimized embodiments, provides a more comprehensive and detailed account of the utility model. However, the scope of protection of this utility model is not limited to the specific embodiments described below. It should be noted that, without affecting the effectiveness of use, the structural features and component dimensions, connection methods, and device sizes in the embodiments of this utility model can be changed.

[0021] Unless otherwise defined, all technical terms used below have the same meaning as commonly understood by those skilled in the art. The terms "first," "second," and similar terms used in this utility model patent application specification and claims do not indicate any order, quantity, or importance, but are merely for the purpose of distinguishing corresponding components. Similarly, the terms "a" or "one," etc., do not indicate a quantity limitation, but rather indicate the presence of at least one. Terms such as "connection" or "connected" are not limited to direct connections, but can refer to indirect connections through other intermediate connecting parts. Terms such as "above," "below," "one side," "the other side," "vertical," and "horizontal" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship also changes accordingly.

[0022] It should be noted that in this embodiment, the following operations are performed: opening windows on the FPC cover film using the windowing mechanism 1 (laser engraving machine); screen printing anti-etching ink on the windowed area of ​​the FPC using the screen printing mechanism 2 (screen printing machine); applying photosensitive dry film to the FPC using the film application mechanism 3 (film application machine); exposing the FPC using the exposure mechanism 4 (exposure machine); developing the circuit diagram on the FPC using the developing mechanism 5 (developing machine); etching the FPC using the etching mechanism 6 (etching machine); and removing the photosensitive dry film from the FPC using the film removal mechanism 7 (film removal machine). All of these operations are the same as the corresponding operations in the prior art and should be considered as known prior art by those skilled in the art. Moreover, removing the anti-etching ink layer from the FPC using the film removal mechanism 7 is the same as removing the photosensitive dry film from the FPC.

[0023] like Figure 1 As shown, the FPC single-sided double-contact hollow finger production system provided by this utility model includes:

[0024] Window opening mechanism 1, used to open windows on the cover film of the FPC;

[0025] The screen printing mechanism 2, connected to the window opening mechanism 1, is used to screen print an anti-etch ink layer on the window opening area of ​​the FPC cover film.

[0026] The film application mechanism 3 is connected to the screen printing mechanism 2 and is used to apply photosensitive dry film onto the FPC.

[0027] Exposure mechanism 4, connected to film application mechanism 3, is used to expose the FPC so that the desired circuit pattern is transferred onto the FPC;

[0028] The developing mechanism 5 is connected to the exposure mechanism 4 and is used to develop the circuit patterns on the FPC.

[0029] Etching mechanism 6, connected to developing mechanism 5, is used to etch the FPC to remove unmasked copper foil on the FPC;

[0030] The film removal mechanism 7, connected to the etching mechanism 6, is used to remove the photosensitive dry film and the anti-etching ink layer on the FPC.

[0031] In the above embodiments, the height of the anti-etching ink layer in the FPC window area is flush with the height of the FPC cover film to ensure that the anti-etching ink layer in the FPC window area is flush with other areas of the FPC.

[0032] In the above embodiments, the window opening mechanism 1 is a laser engraving machine, the screen printing mechanism 2 is a screen printing machine, the film application mechanism 3 is a film application machine, the exposure mechanism 4 is an exposure machine, the developing mechanism 5 is a developing machine, the etching mechanism 6 is an etching machine, and the film removal mechanism 7 is a film removal machine.

[0033] In the above embodiments, by adding a screen printing mechanism 2 to the production system, an anti-etching ink layer can be screen printed in the windowed area of ​​the FPC cover film. This ensures that the height of the anti-etching ink layer in the windowed area is at the same level as the height of other areas, thereby solving the technical problem in the prior art where a step with a height difference is formed after the FPC cover film is opened, causing film bubbles to form during the subsequent film application process of the film application mechanism 3. Therefore, the FPC products produced by the FPC single-sided double-contact hollow finger production system provided in this application will not generate film bubbles in the FPC windowed area, thus protecting the FPC copper surface, ensuring the integrity of the FPC copper surface, and effectively reducing the scrap rate of FPC products.

[0034] In some embodiments, a pressing mechanism 8 is also included, which is disposed between the window opening mechanism 1 and the screen printing mechanism 2, and the pressing mechanism 8 is used to press the cover film attached to the FPC.

[0035] In the above embodiments, the pressing mechanism 8 is a pressing machine. This pressing mechanism 8 is used to press the cover film attached to the FPC, thereby ensuring the adhesion performance between the cover film and the FPC.

[0036] In some embodiments, the window opening mechanism 1 is connected to the screen printing mechanism 2, the screen printing mechanism 2 to the film application mechanism 3, the film application mechanism 3 to the exposure mechanism 4, the exposure mechanism 4 to the developing mechanism 5, the developing mechanism 5 to the etching mechanism 6, and the etching mechanism 6 to the film removal mechanism 7 via conveyor belts.

[0037] In the above embodiments, by setting up conveyor belts in the production system to connect various mechanisms, the labor intensity of operators is reduced and the automation level of the production system is effectively improved.

[0038] In some embodiments, the window opening mechanism 1 is connected to the pressing mechanism 8 and the pressing mechanism 8 is connected to the screen printing mechanism 2 via a conveyor belt.

[0039] In the above embodiments, by setting a conveyor belt between the window opening mechanism 1 and the pressing mechanism 8 and between the pressing mechanism 8 and the screen printing mechanism 2, the labor intensity of the operators is reduced, the automation level of the production system is further improved, and the production efficiency is increased.

[0040] The above provides a detailed description of the FPC single-sided double-contact hollow finger production system provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the core idea of ​​this utility model. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
