Description

Technical Field

[0001] This invention relates to the field of electronic component packaging, and more particularly to an electronic packaging cover tape specifically designed for single-row, multi-layer derivative packaging tapes. Prior Technology

[0002] With the popularization of emerging technologies such as the Internet of Things (IoT), 5G, artificial intelligence (AI), self-driving cars, electric vehicles (EVs), and smart wearable devices, the market demand for electronic components (including active components such as transistors, diodes, integrated circuits, and passive components such as resistors, capacitors, and inductors) is increasing rapidly.

[0003] As electronic components become smaller and their performance requirements become more stringent, the demands on packaging technology are also increasing, especially in terms of component loading, packaging, storage and protection, where it is urgent to break through the bottlenecks of existing technologies.

[0004] Most common electronic component carrier tapes or packaging tapes currently use a single-row, single-recessed, or single-empty-frame structure, which can only load one electronic component per unit travel length, thus limiting the efficiency of the production line and the packaging speed.

[0005] Furthermore, even in the existing improved schemes with multiple columns, poor sealing can easily lead to incomplete sealing of packaging bags or mutual interference between adjacent bags, which can cause components to slip out or be mixed up during transportation or handling.

[0006] On the other hand, with the increasing global emphasis on sustainable development and social responsibility, corporate ESG (Environmental, Social, and Governance) needs and performance have become important indicators of corporate operations, and are gradually influencing the decisions of investors, government agencies, consumers, and other stakeholders. Among these, environmental needs, particularly reducing carbon footprint, energy efficiency, resource recycling, and waste reduction, have become fundamental requirements for companies to comply with ESG standards.

[0007] Therefore, there is a great need for an innovative multi-layer derivative packaging roll and its dedicated electronic packaging cover, which utilizes a single-layer loading method to improve the efficiency of unit packaging material use and reduce the material cost per unit of packaging material, thereby solving all the problems of the aforementioned conventional technologies. Summary of the Invention

[0008] To address the aforementioned problems, this invention provides a special electronic packaging cover tape for single-row, multi-layered derivative packaging reels, comprising a light-transmitting substrate layer, an adhesive layer, and a pressure-sensitive adhesive layer stacked sequentially from top to bottom. In this invention, the special electronic packaging cover tape for single-row, multi-layered derivative packaging reels is a multi-layered composite structure, comprising: a light-transmitting substrate layer, possessing light transmittance and heat resistance; an adhesive layer stacked on one lower surface of the light-transmitting substrate layer; and a pressure-sensitive adhesive layer partially stacked and / or arranged on one lower surface of the adhesive layer; wherein the pressure-sensitive adhesive layer has a lateral spacing and / or a longitudinal spacing, the lateral spacing and / or the longitudinal spacing being set to a range of 0.5~50mm to accommodate the pocket size of a single-row, multi-layered derivative packaging reel, and the lateral spacing and / or the longitudinal spacing being smaller than the pocket size of the single-row, multi-layered derivative packaging reel.

[0009] In one embodiment of the present invention, the thickness of the light-transmitting substrate layer is set to 10~50μm, and the light-transmitting substrate layer includes a plastic film material, which includes at least one of PET, PP, PE, PET / PE or PET / PP. In one embodiment of the present invention, the thickness of the adhesive layer is set to 0.5~50mm, and is less than or equal to the thickness of the light-transmitting substrate layer. The adhesive layer includes at least one of acrylic adhesive, silicone adhesive, PU adhesive, rubber or polymer adhesive.

[0010] In one embodiment of the present invention, the adhesive layer further includes an antistatic coating or antistatic particles.

[0011] In one embodiment of the present invention, the thickness of the pressure-sensitive adhesive layer is set to 1~20μm, which is less than the thickness of the light-transmitting substrate layer and the adhesive layer. The pressure-sensitive adhesive layer includes at least one of acrylic adhesive, silicone adhesive, PU adhesive, rubber or polymer adhesive, and the materials selected for the pressure-sensitive adhesive layer and the adhesive layer may be the same or different.

[0012] In one embodiment of the present invention, the dimensions of both the lateral spacing and the longitudinal spacing of the pressure-sensitive adhesive layer are smaller than the pocket size of the single-row composite derivative packaging tape.

[0013] In one embodiment of the present invention, the pressure-sensitive adhesive layer is arranged in strips at intervals and extends uniformly along the longitudinal direction of the single-row composite derivative packaging roll special electronic packaging cover strip 1.

[0014] In one embodiment of the present invention, the pressure-sensitive adhesive layer is arranged in a dotted pattern at intervals, or the pressure-sensitive adhesive layer is arranged in a dotted pattern with alternating intervals.

[0015] In one embodiment of the present invention, the pressure-sensitive adhesive layer is arranged in a combination of strips and dots.

[0016] In one embodiment of the present invention, the ranges of the lateral interval and the longitudinal interval are set to be different.

[0017] The single-row composite derivative packaging tape for electronic packaging provided by this invention can maintain high light transmittance and heat resistance. Through its multi-layer structure and specially arranged pressure-sensitive adhesive layer, it forms an independent sealing area after heat sealing / pressing with the packaging tape, thereby effectively preventing electronic components from slipping out or being mixed up. It also has the technical effects of anti-static protection, packaging stability and material cost reduction. Simple Explanation of the Diagram

[0025] The following description, in conjunction with the accompanying drawings and component symbols, provides a more detailed account of the embodiments of the present invention, so that those skilled in the art can implement it after studying this specification.

[0026] Referring to Figures 1A, 1B, and 3, the electronic packaging cover 1 of the single-row composite derivative packaging roll of the present invention has a multi-layer structure, comprising a light-transmitting substrate layer 10, an adhesive layer 20, and a pressure-sensitive adhesive layer 30 stacked sequentially from top to bottom. The light-transmitting substrate layer 10 provides light transmittance and heat resistance. The adhesive layer 20 becomes sticky after heating or applying pressure, allowing it to adhere to the single-row composite derivative packaging roll 2. The pressure-sensitive adhesive layer 30 has slight stickiness, ensuring independent sealing of each pocket 40, forming an independent sealing area S, and preventing electronic components 50 from sliding or being mixed up during transportation.

[0027] In one embodiment of the present invention, the thickness of the light-transmitting substrate layer 10 is 10-50 μm, preferably 12-40 μm, and more preferably 15-30 μm. The light-transmitting substrate layer 10 may be made of at least one of the following plastic film materials: PET (polyethylene terephthalate), PP (polypropylene), PE (polyethylene), PET / PE, or PET / PP. Furthermore, the light-transmitting substrate layer 10 has a visible light transmittance of 85% or more and can withstand ambient temperatures above 90°C to ensure the stability of the component encapsulation.

[0028] In one embodiment of the present invention, the thickness of the adhesive layer 20 is 10-50 μm, preferably 12-40 μm, and more preferably 15-20 μm. In a preferred embodiment of the present invention, the thickness of the adhesive layer 20 is less than the thickness of the light-transmitting substrate layer 10. The adhesive layer 20 may be selected from at least one of acrylic adhesive, silicone, PU adhesive, rubber, or polymeric adhesive. Preferably, the adhesive layer 20 includes an antistatic coating or antistatic particles (such as one of PEDOT, carbon black, or conductive polymer), thereby reducing static electricity accumulation and preventing damage to the electronic component 50 due to static electricity. In addition, space is reserved on the adhesive layer 20 for bonding with the single-row composite derivative packaging tape 2.

[0029] In one embodiment of the present invention, the thickness of the pressure-sensitive adhesive layer 30 is 1-20 μm, preferably 1-15 μm, and more preferably 1-10 μm. In a preferred embodiment of the present invention, the thickness of the pressure-sensitive adhesive layer 30 is less than the thickness of the light-transmitting substrate layer 10 and the adhesive layer 20. The pressure-sensitive adhesive layer 30 may be selected from at least one of acrylic adhesive, silicone, PU adhesive, rubber, or polymeric adhesive. Preferably, the materials used for the pressure-sensitive adhesive layer 30 and the adhesive layer 20 may be the same or different. Furthermore, the pressure-sensitive adhesive layer 30 can be modified through chemical and physical methods to change the microstructure of the film surface, thereby adjusting its surface energy and generating appropriate adhesion to ensure sealing performance.

[0030] Furthermore, the pressure-sensitive adhesive layers 30 have a lateral spacing L1 and a longitudinal spacing L2, with dimensions ranging from 0.5 to 50 mm, smaller than the pocket 40 size of the single-row composite derivative packaging roll 2, to ensure sealing integrity. The aforementioned lateral spacing L1 and longitudinal spacing L2 can be the same or different, adjusted according to packaging requirements. When the adhesive layer 20 is stacked on the lower surface of the light-transmitting substrate layer 10 and sequentially stacked with the pressure-sensitive adhesive layer 30, it can slightly adhere to the surface of the single-row composite derivative packaging roll 2, forming an independent sealing area S. This ensures the independent sealing characteristics between the pockets 40 of each single-row composite derivative packaging roll, unaffected by adjacent pockets, effectively preventing electronic components from sliding or being mixed up.

[0031] Furthermore, in this invention, the transverse spacing L1 and longitudinal spacing L2 of the pressure-sensitive adhesive layer 30 are typically designed to be 5% to 15% smaller than the size of the pocket 40 in the single-row composite derivative packaging roll 2, preferably less than 10%.

[0032] Referring to Figure 2, in one embodiment of the present invention, the pressure-sensitive adhesive layers 30 are arranged in a strip-like pattern with a lateral spacing L1 ranging from 0.5 to 50 mm. The strip-like pressure-sensitive adhesive layers 30 extend uniformly along the longitudinal direction of the single-row composite derivative packaging roll-specific electronic packaging cover tape 1. After heat sealing or pressing, the adhesive layers 20 on both sides can firmly bond to the carrier tape, ensuring that the electronic components 50 will not fall off due to shaking during storage. The strip-like arrangement reduces the use of adhesive material, lowers manufacturing costs, and ensures appropriate sealing strength.

[0033] Referring to Figure 3, in another embodiment of the present invention, the pressure-sensitive adhesive layer 30 is replaced with a dotted arrangement, the lateral spacing L1 and longitudinal spacing L2 of which also range from 0.5 to 50 mm. This dotted arrangement design improves the uniformity of the seal, allowing the pocket 40 of the single-row composite derivative packaging roll 2 to be sealed independently and adaptable to electronic components 50 of different sizes and shapes. Simultaneously, the dotted arrangement reduces the adhesive area, further reducing material usage and improving environmental friendliness and recyclability.

[0034] Referring to Figure 4, in another embodiment of the present invention, the pressure-sensitive adhesive layer 30 is arranged in a combination of strips and dots, with the strip portion providing strong sealing and the dot portion ensuring that local sealing is not affected.

[0035] Referring to Figure 5, in another embodiment of the present invention, the pressure-sensitive adhesive layer 30 is arranged in a high-density dot pattern, and preferably, the dot pattern is staggered to ensure uniform sealing.

[0036] This invention utilizes a multi-layer composite structure and a locally pressure-sensitive adhesive layer arrangement design to achieve the following technical effects: the light-transmitting substrate layer has excellent light transmittance and heat resistance; the adhesive layer generates good adhesion after heating or pressurization and has antistatic function, enabling the cover tape to adhere firmly to the carrier tape and ensuring a stable and reliable encapsulation process.

[0037] The special arrangement design of the pressure-sensitive adhesive layer, after being arranged in dots, strips or staggered patterns, can form an independent sealing area on the packaging roll, effectively preventing electronic components from sliding or being mixed up during transportation or storage due to incomplete sealing.

[0038] Furthermore, by rationally controlling the thickness of each layer of material and the local arrangement, not only is the amount of material used reduced, but the overall packaging efficiency is also improved, thereby achieving the goals of reducing production costs and environmental protection.

[0039] The above description is merely a preferred embodiment for explaining the present invention and is not intended to limit the present invention in any way. Therefore, any modifications or changes made to the present invention under the same creative spirit should still be included within the scope of protection intended by the present invention.
