Description

Technical Field

[0001] The utility model relates to the technical field of electronic materials, in particular to a multifunctional electronic adhesive tape assembly. Background Art

[0002] With the rapid development of electronic technology, the complexity and integration of electronic equipment are increasing day by day. In many aspects of the manufacturing, assembly, maintenance and protection of modern electronic equipment, tape plays an indispensable and key role. Tape can not only be used to fix electronic components to ensure their stability and safety inside the equipment, but also play an important role in circuit connection and insulation protection. In addition, in terms of the protection of electronic equipment, tape can prevent external factors such as dust and water vapor from corroding the inside of the equipment, providing a good environmental guarantee for the normal operation of the equipment. It can be said that electronic tape components are an important support for the normal operation and stable performance of electronic equipment.

[0003] However, traditional electronic tapes are often relatively single in function and cannot meet the increasingly diverse and complex needs. In some special environments, such as high temperature, high humidity, strong electromagnetic interference, etc., electronic equipment needs to have multiple properties such as conductivity, insulation, heat dissipation, moisture resistance, and electromagnetic interference shielding. However, the existing single-function tapes obviously cannot meet these comprehensive needs. This leads to the need to combine and superimpose multiple different types of tapes in practical applications, which not only increases the complexity and cost of operation, but also may affect the overall performance due to compatibility issues between different tapes. Moreover, the reliability and stability of this patchwork solution are difficult to fully guarantee when facing complex and harsh working environments. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-3 The multifunctional electronic tape assembly comprises a tape body 1, which is carefully composed of a plurality of functional layers, namely a core conductive layer 2, an intermediate insulating layer 3, a heat dissipation layer 4, a moisture-proof layer 5 and an electromagnetic shielding layer 6.

[0023] In the entire structure, the core conductive layer 2 is located at the innermost side of the tape body 1. It is in direct contact with the electronic components and undertakes the key task of conducting current and connecting the electronic components, thereby ensuring that the circuits in the electronic equipment can be normally conducted. The thickness of this core conductive layer 2 is 0.02mm, and the material selected is conductive silver paste with excellent conductive properties. Conductive silver paste has good uniformity and stability, and can provide a stable and efficient conductive path for electronic components.

[0024] Next to the outer side of the core conductive layer 2 is the middle insulating layer 3, which is 0.1 mm thick and made of polyester film. The middle insulating layer 3 plays a vital role in effectively isolating the current, preventing dangerous situations such as leakage and short circuit, and providing reliable protection for the safe operation of electronic equipment.

[0025] The heat dissipation layer 4 is installed on the outside of the middle insulating layer 3, and its thickness is 0.05mm. The material is copper foil with good thermal conductivity. During the operation of electronic equipment, electronic components will generate heat. The heat dissipation layer 4 can quickly conduct the heat away, avoiding equipment failure or performance degradation due to overheating, and ensuring stable operation and long life of the equipment.

[0026] Located outside the heat dissipation layer 4 is a moisture-proof layer 5, which is 0.06 mm thick and made of polytetrafluoroethylene film. This moisture-proof layer 5 can effectively block the intrusion of external moisture and protect the internal layers and electronic components from the influence of the humid environment, especially in an environment with high humidity, which can significantly improve the reliability and stability of electronic equipment.

[0027] The electromagnetic shielding layer 6 is installed on the outside of the moisture-proof layer 5, has a thickness of 0.04 mm, and is made of copper mesh. The electromagnetic shielding layer 6 can effectively shield the external electromagnetic interference, ensuring that the circuits and signals inside the electronic device are not interfered by the external electromagnetic environment, thereby ensuring that the electronic device can work stably and accurately.

[0028] The core conductive layer 2, the intermediate insulating layer 3, the heat dissipation layer 4, the moisture-proof layer 5 and the electromagnetic shielding layer 6 are not in direct contact, but are tightly and firmly connected through the adhesive layer 7. The adhesive layer 7 has a thickness of 5 μm and is made of an epoxy adhesive with high bonding strength and chemical stability, which ensures that the layers will not be delaminated or fall off during long-term use.

[0029] A protective coating 8 is also applied on the surface of the electromagnetic shielding layer 6. The thickness of the protective coating 8 is 20 μm, and the material is polyimide which is resistant to high temperature and chemical corrosion and has excellent insulation performance. This protective coating 8 can not only further enhance the protective performance of the entire tape assembly, but also improve its wear resistance, scratch resistance and aging resistance, so that it can maintain good performance and appearance in various complex and harsh environments.

[0030] When the utility model is used, when the electronic device is running, the core conductive layer 2 located on the innermost side plays a role first. Because it is made of conductive silver paste and is in direct contact with the electronic components, it can smoothly conduct current and establish a stable circuit connection. The intermediate insulating layer 3 then plays a key isolation role. Made of polyester film, it effectively prevents the current conducted by the core conductive layer 2 from leaking outward, prevents faults such as short circuits, and ensures that the current flows along a predetermined path. The heat dissipation layer 4 uses the good thermal conductivity of copper foil to quickly absorb and conduct the heat generated by the operation of the electronic components. The heat is transferred from the inside to the outside, avoiding the adverse effects of local overheating on the performance and life of the electronic equipment. The moisture-proof layer 5 forms a solid barrier with the characteristics of polytetrafluoroethylene film to block the invasion of external moisture and humid air. Even in a humid environment, it can protect the internal layers and electronic components from moisture erosion and maintain their normal working state. The electromagnetic shielding layer 6 is composed of a copper mesh, which can effectively shield the interference of the external electromagnetic field. It prevents external electromagnetic signals from interfering with the circuits and signals inside the electronic equipment, ensuring the stable operation of the electronic equipment and the accuracy of signal transmission. Each layer is tightly connected by an adhesive layer 7 composed of epoxy adhesive, which ensures that each functional layer works together in long-term use without delamination or displacement. The outermost polyimide protective coating 8 provides additional protection, enhances the wear resistance, scratch resistance and aging resistance of the tape body 1, and enables it to function stably for a long time in a complex and changeable use environment.

[0031] In summary, the various layers of the multifunctional electronic tape assembly work together to provide electronic devices with multiple key functions such as conductivity, insulation, heat dissipation, moisture resistance, electromagnetic shielding and protection, ensuring that electronic devices operate safely, stably and efficiently under various conditions.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
