Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, specifically to paper-based cover film for circuit boards and paper-based cover film circuit boards. Background Technology

[0002] A printed circuit board (PCB) is a support structure and carrier in electronic devices used to fix and support electronic components and provide electrical connections. It acts as the skeleton of an electronic system, ensuring smooth current flow and efficient signal transmission, while providing insulation protection against short circuits and oxidation. The paper-based cover film for PCBs is a new type of environmentally friendly cover material used to replace traditional high-temperature resin cover films (such as polyimide PI film). It is mainly made of paper substrate coated with thermosetting or thermoplastic adhesives and is attached to the surface of the PCB through windowed alignment to protect the circuitry.

[0003] However, existing paper-based cover films for circuit boards and paper-based cover film circuit boards cannot effectively reinforce and install the film during use, making it prone to detachment, reducing its stability and installation efficiency. Furthermore, the installation direction of the main board cannot be adjusted, preventing effective switching and plugging. Consequently, its installation method is limited, making it unsuitable for different installation methods, thus reducing its efficiency and applicability. Therefore, we propose paper-based cover films for circuit boards and paper-based cover film circuit boards. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0016] like Figures 1 to 5 As shown, the paper-based cover film of the circuit board includes: a film body 1, a number of evenly distributed first docking holes 2 are opened on the top of the film body 1, first mounting holes 5 are opened near the four corners of the top of the film body 1, and adhesive tape 3 is attached to the top of the film body 1 near the front and rear sides.

[0017] Several evenly distributed L-shaped snap-fit ​​blocks 4 are connected to the front and rear sides of the membrane body 1, and two adhesive tapes 3 are arranged symmetrically about the central axis of the membrane body 1.

[0018] In this embodiment, it can effectively reinforce and install the membrane 1, thereby making it less prone to detachment during use and improving its stability and installation efficiency.

[0019] The paper-based cover film circuit board includes a main board body 6. The top of the main board body 6 has several evenly distributed second mating holes 11. The top of the main board body 6 has second mounting holes 10 near the four corners. The front and rear sides of the main board body 6 have bonding grooves 9. The front and rear side walls of the main board body 6 are connected to fixing blocks 14 by bolts near the left and right sides. The two fixing blocks 14 located on the front or rear side are movably connected to each other by a rotating shaft and bearing. The front end of the rotating shaft on the front side of the bonding plate 15 passes through the inner ring of the bearing and is fitted with a fastening nut. The top of the bonding plate 15 has stabilizing holes 8 near the four corners. The main board body 6 has several evenly distributed first ventilation holes 7 along the front-rear direction. The main board body 6 has several evenly distributed second ventilation holes 13 along the left-right direction. The top of the main board body 6 has several evenly distributed L-shaped grooves 12 near the left and right sides.

[0020] Implementation plan: This allows for adjustment of the installation direction of the motherboard body 6, enabling effective switching and plugging, thus avoiding a single installation method and allowing it to adapt to different installation methods, thereby improving its efficiency and applicability.

[0021] Working principle: In use, the membrane body 1 is first aligned with the main body 6, and the first mating hole 2 and the second mating hole 11 are aligned. The membrane body 1 is then attached to the top of the main body 6, and the L-shaped snap-fit ​​block 4 is snapped into the L-shaped groove 12. Then, the adhesive tape 3 is folded so that it fits into the fitting groove 9, which effectively reinforces and installs the membrane body 1, making it less likely to detach during use, thus improving its stability and installation efficiency. Loosening the nut allows the adhesive plate 15 to be rotated to switch its direction, thereby adjusting the installation direction of the main body 6 and enabling effective switching of the insertion. This avoids a single installation method and allows it to adapt to different installation methods, improving its efficiency and applicability. Finally, it is installed through the first mounting hole 5, mounting hole 10, and stabilizing hole 8.
