Description

Technical Field

[0001] This utility model relates to the field of electronic tape technology, and in particular to high heat dissipation and light-shielding electronic tape. Background Technology

[0002] With the increasing demand for thinner and lighter electronic products, adhesive tape is often used to bond and fix the back cover to the body of electronic products. Electronic tape, also known as electrical tape, is mainly used to prevent leakage and provide insulation. It has good insulation, flame retardancy, and high-temperature resistance. Electronic tape is crucial for the connection of electronic components, providing good fixation and protection, allowing the electronic components to operate normally. For example, a Chinese patent discloses an electronic tape with application number CN201020186141.4. This electronic tape overcomes defects such as poor transparency, poor moisture resistance, and easy formation of burrs and paper scraps. It has good transparency, good moisture resistance, and is not prone to burrs. However, during use, it loses its adhesiveness as the temperature of the electronic components rises, and it generates a certain thermal resistance, increasing the resistance to heat transfer and slowing down heat dissipation, thus affecting the heat dissipation of electronic components. Utility Model Content

[0003] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a high heat dissipation and light-shielding electronic tape. The heat-dissipating double-sided adhesive on the surface of the adhesive layer can form a heat-conducting channel through the internal high thermal conductivity ceramic particles, connecting the heat-generating element and the heat sink. At the same time, the internal heat-conducting film can accelerate the heat exchange rate and transfer heat quickly. In addition, the external light-shielding film can reflect light, effectively preventing strong light from causing certain damage to electronic components.

[0004] This utility model also provides an electronic tape with the aforementioned high heat dissipation and light-shielding properties, comprising: an electronic tape body, the electronic tape body being composed of a base layer, an adhesive layer, a release layer, a conductive layer, and an insulating layer; a thermally conductive film is fixedly connected to one side of the base layer; the side of the thermally conductive film away from the base layer is fixedly connected to the adhesive layer; the other side of the base layer is fixedly connected to the release layer; the side of the release layer away from the base layer is fixedly connected to the conductive layer; and the side of the conductive layer away from the release layer is fixedly connected to the insulating layer. Through these components, and via the heat-dissipating double-sided adhesive on the surface of the adhesive layer, a heat-conducting channel is formed by the internal high thermal conductivity ceramic particles, connecting the heat-generating element and the heat-dissipating element. Simultaneously, the internal thermally conductive film accelerates the heat exchange rate, rapidly transferring heat. Furthermore, the external light-shielding film reflects light, effectively preventing strong light from damaging electronic components.

[0005] According to the high heat dissipation and light-shielding electronic tape of this utility model, a heat-dissipating double-sided adhesive is provided on the side of the adhesive layer away from the thermally conductive film, and a release paper is provided on the side of the heat-dissipating double-sided adhesive away from the adhesive layer. These components improve the heat conduction channel, providing excellent thermal conductivity and strong adhesion, enabling the heat-generating element and the heat-dissipating element to be fixed together, thereby enhancing the heat dissipation effect. This effectively reduces the resistance to heat transfer, improves heat dissipation efficiency, and maintains adhesion for a long time without easily detaching. It can also adapt to uneven surfaces.

[0006] According to the high heat dissipation and light-shielding electronic tape of this utility model, an adhesive layer is fixedly connected around the perimeter of the adhesive layer, and an organic high-temperature adhesive is applied to the surface of the adhesive layer. These components provide high-temperature resistance, chemical corrosion resistance, and excellent adhesion, effectively preventing insufficient adhesion at the bottom edges and thus preventing localized detachment.

[0007] According to the high heat dissipation and light-shielding electronic tape of this utility model, a recessed portion is fixedly connected to the side of the release layer away from the substrate, and a protruding portion is fixedly connected inside the recessed portion. The side of the protruding portion away from the recessed portion is fixedly connected to the conductive layer. Through these components, the release layer can effectively prevent the erosion of dust and moisture, providing excellent protection for the electronic tape itself.

[0008] According to the high heat dissipation and light-shielding electronic tape of this utility model, a light-shielding film is fixedly connected to the side of the insulating layer away from the conductive layer, and a frosted layer is fixedly connected to the side of the light-shielding film away from the insulating layer. These components provide isolation, protection, and coverage for electronic components. The light-shielding film effectively reduces sunlight exposure and reflects strong light, effectively preventing damage to electronic components from strong light.

[0009] According to the high heat dissipation and light-shielding electronic tape of this utility model, a fixing sleeve is fixedly connected to the surface of the frosted layer. The side surface of the fixing sleeve is fixedly connected to the separation layer, and the side surface of the fixing sleeve is fixedly connected to the conductive layer. Through these components, the fixing sleeve can reinforce the edge portion of the electronic tape body, preventing the edge structure from dispersing and stabilizing the internal structure.

[0010] Beneficial effects: Compared with existing technologies, this new high heat dissipation and light-shielding electronic tape has a heat-dissipating double-sided adhesive layer on the adhesive surface. Through the high thermal conductivity ceramic particles inside, it forms a heat-conducting channel to connect the heat-generating element and the heat-dissipating element. At the same time, the heat-conducting film inside can accelerate the heat exchange rate and transfer heat quickly. In addition, the light-shielding film on the outside can reflect light and effectively prevent strong light from causing damage to electronic components. Attached Figure Description

[0019] Reference Figure 1-4 This utility model embodiment of a high heat dissipation and light-shielding electronic tape includes: an electronic tape body 1, which is composed of a base layer 2, an adhesive layer 7, a release layer 6, a conductive layer 4, and an insulating layer 5. A thermally conductive film 10 is fixedly connected to one side of the base layer 2, which can effectively conduct heat and improve the heat transfer efficiency, thus preventing local overheating of electronic components. The side of the thermally conductive film 10 away from the base layer 2 is fixedly connected to the adhesive layer 7, and the other side of the base layer 2 is fixedly connected to the release layer 6, which can effectively prevent the intrusion of dust and other contaminants and has a protective function. The side of the release layer 6 away from the base layer 2 is fixedly connected to the conductive layer 4, and the side of the conductive layer 4 away from the release layer 6 is fixedly connected to the insulating layer 5.

[0020] A heat-dissipating double-sided adhesive 12 is provided on the side of the adhesive layer 7 away from the heat-conducting film 10. A release paper 11 is provided on the side of the heat-dissipating double-sided adhesive 12 away from the adhesive layer 7 to isolate and protect the adhesive part of the heat-dissipating double-sided adhesive 12, preventing the adhesive part from adhering to other surfaces when not in use. An adhesive layer 3 is fixedly connected around the adhesive layer 7, and the organic high-temperature adhesive 14 is applied to the area. The surface of the adhesive layer 3 is provided with organic high-temperature adhesive 14.

[0021] The side of the separation layer 6 away from the base layer 2 is fixedly connected to a recessed part 15, which cooperates with the protruding part 16 of the conductive layer 4. The recessed part 15 is fixedly connected to the protruding part 16. Through the mutual fixed engagement with the recessed part 15, the connection between the separation layer 6 and the conductive layer 4 is made tighter and more stable, which can prevent them from falling off during use. The side of the protruding part 16 away from the recessed part 15 is fixedly connected to the conductive layer 4.

[0022] A light-shielding film 9 is fixedly connected to the side of the insulating layer 5 away from the conductive layer 4 to reflect strong light and effectively protect electronic components from damage caused by strong light. A frosted layer 8 is fixedly connected to the side of the light-shielding film 9 away from the insulating layer 5 to reduce heat and halo, effectively isolate ultraviolet rays, and improve the wear resistance and corrosion resistance of the surface of the electronic tape body 1. A fixing sleeve 13 is fixedly connected to the surface of the frosted layer 8. The side surface of the fixing sleeve 13 is fixedly connected to the separation layer 6 and the side surface of the fixing sleeve 13 is fixedly connected to the conductive layer 4.

[0023] Working principle: First, peel the release paper 11 off the surface of the adhesive layer 7, exposing the heat-dissipating double-sided adhesive 12 on the surface of the adhesive layer 7. Then, peel off the release paper 11 around the adhesive layer 3. Next, bond the center of the heat-dissipating double-sided adhesive 12 to the bonding area. Then, press the edges of the adhesive layer 3, which are coated with organic high-temperature adhesive 14, to ensure a tight connection between the adhesive layer 7 and the electronic component. When the temperature of the electronic component rises during operation, the heat-dissipating double-sided adhesive 12 conducts heat through the high thermal conductivity ceramic particles inside. The channel connects the heating element and the heat sink. At the same time, the heat-conducting film 10 inside can accelerate the heat exchange rate and transfer heat quickly. The conductive layer 4 on the electronic tape body 1 can effectively prevent the local accumulation of static electricity through the internal conductive fibers and release static electricity to the atmosphere through corona discharge capability. When the electronic components malfunction and leakage occurs, the insulating layer 5 can effectively prevent the leakage of current. The outside of the electronic tape body 1 is equipped with a light-shielding film 9, which has good heat insulation performance and can effectively block direct sunlight.
