[0005] The conductive cloth of the aforementioned laptop touch button tape is bonded to both sides of a first high-adhesion ultra-low resistance adhesive layer and a second high-adhesion ultra-low resistance adhesive layer, respectively. Then, a first release film and a second release film are respectively attached to the first and second high-adhesion ultra-low resistance adhesive layers. After baking and curing, a high-adhesion ultra-low resistance conductive tape is formed.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] like Figure 1As shown, an embodiment of this application provides a laptop computer touch button tape, including a high-adhesion ultra-low resistance conductive tape 1 attached to the touch button. The high-adhesion ultra-low resistance conductive tape 1 includes a conductive cloth 11. A first high-adhesion ultra-low resistance adhesive layer 12 is disposed on one side of the conductive cloth 11. A first release film 13 is disposed on the side of the first high-adhesion ultra-low resistance adhesive layer 12 away from the conductive cloth 11. A second high-adhesion ultra-low resistance adhesive layer 14 is disposed on the other side of the conductive cloth 11. A second release film 15 is disposed on the side of the second high-adhesion ultra-low resistance adhesive layer 14 away from the conductive cloth 11. The resistance of the first high-adhesion ultra-low resistance adhesive layer 12 and the second high-adhesion ultra-low resistance adhesive layer 14 is 0.01-0.02 ohms, and the peel force is 2000-2500gf.

[0020] Specifically, the conductive cloth 11 is a 0.05mm woven conductive cloth. A first high-adhesion ultra-low resistance adhesive layer 12 with a thickness of 0.025mm is coated on one side of the woven conductive cloth, and a second high-adhesion ultra-low resistance adhesive layer 14 with a thickness of 0.025mm is coated on the other side of the woven conductive cloth, giving both sides of the woven conductive cloth high adhesion. Then, a first release film 13 with a thickness of 0.05mm is attached to the side of the first high-adhesion ultra-low resistance adhesive layer 12 away from the woven conductive cloth, and a second release film 15 with a thickness of 0.05mm is attached to the side of the second high-adhesion ultra-low resistance adhesive layer 14 away from the woven conductive cloth. After baking and curing, a high-adhesion ultra-low resistance conductive tape 1 is formed, which is then applied to the touch button. The high-adhesion ultra-low resistance conductive tape 1 has a resistance of 0.01-0.02 ohms per square inch and a peel force of 2000-2500gf.

[0021] The low resistance value in this field is around 1 ohm, and the ultra-low resistance value is 0.01-0.02 ohms. The peel force of conventional ordinary adhesives in this field is 1000-1500 gf, and the high-tack peel force generated by the first high-tack ultra-low resistance adhesive layer 12 with a thickness of 0.025 mm and the second high-tack ultra-low resistance adhesive layer 14 with a thickness of 0.025 mm is 2000-2500 gf.

[0022] The first high-viscosity ultra-low resistance adhesive layer 12 and the second high-viscosity ultra-low resistance adhesive layer 14 are made of adhesive, curing agent, and 300-mesh conductive powder. They are prepared by mixing the adhesive, curing agent, and 300-mesh conductive powder in a mass ratio of 100:10:5, stirring at 500 rpm for 30 minutes at 25°C, and then curing at 80°C for 2 hours. The adhesive is an acrylic adhesive, specifically model PS8281E / YWGS83 from Kunshan Shimei New Material Technology Co., Ltd., the curing agent is model PX2300AM / YWDS20 from Kunshan Shimei New Material Technology Co., Ltd., and the conductive powder is conductive powder produced by Changsha Liyou Metal Materials Co., Ltd. The first high-viscosity ultra-low resistance adhesive layer 12 and the second high-viscosity ultra-low resistance adhesive layer 14 can use existing products from companies such as Henkel, 3M, and DuPont. Alternatively, the adhesive layer prepared using the above material combination and process conditions can have a resistivity of 0.01-0.02 ohms and an adhesion strength of 10 N / cm. 2 .

[0023] like Figure 2 As shown, the touch button, from top to bottom, comprises a black nano-touch panel 2, a copper foil 3, a chip 4, and a stainless steel sheet 5. High-adhesion ultra-low resistance conductive tape 1 can be cut into strips of 5mm*35mm. The first release film 13 is peeled off, and one side of the high-adhesion ultra-low resistance conductive tape 1 is attached to the side of the chip 4 closest to the stainless steel sheet 5. The second release film 15 is peeled off, and the other side of the high-adhesion ultra-low resistance conductive tape 1 is attached to the stainless steel sheet 5. When a finger slides on the touch button, a certain amount of pressure is generated, causing the black nano-touch panel 2, copper foil 3, chip 4, high-adhesion ultra-low resistance conductive tape 1, and stainless steel sheet 5 to touch and connect, forming a conductive path.

[0024] In the above structure, a high-adhesion, ultra-low-resistance conductive tape 1 is applied between the touch button chip 4 and the stainless steel sheet 5 to form a good conductive path. This laptop touch button tape has high adhesion, ultra-low resistance, and shielding effectiveness, thereby improving the sensitivity and reliability of the touch button and has broad application prospects.

[0025] like Figure 1 As shown, in one embodiment, the conductive cloth 11 of the laptop touch button tape is a woven conductive cloth with a thickness of 0.05mm. Using a 0.05mm thick woven conductive cloth provides good conductivity, conformability, and shielding, effectively reducing electromagnetic interference.

[0026] like Figure 1As shown, in one embodiment, the thicknesses of the first high-adhesion ultra-low resistance adhesive layer 12 and the second high-adhesion ultra-low resistance adhesive layer 14 of the laptop touch button tape are both 0.025 mm. The adhesion force of the 0.025 mm thick first high-adhesion ultra-low resistance adhesive layer 12 and the second high-adhesion ultra-low resistance adhesive layer 14 is 10 N / cm. 2 With a peel strength of 2000-2500gf, the high-adhesion, ultra-low-resistance conductive tape 1 is firmly adhered to the touch button.

[0027] like Figure 1 As shown, in one embodiment, the thicknesses of the first release film 13 and the second release film 15 of the laptop touch button tape are 0.05 mm, respectively. Using a 0.05 mm thick first release film 13 and second release film 15 effectively protects the first high-adhesion ultra-low resistance adhesive layer 12 and the second high-adhesion ultra-low resistance adhesive layer 14, facilitates peeling, and optimizes the thickness of the high-adhesion ultra-low resistance conductive tape 1.

[0028] like Figure 1 As shown, in one embodiment, the conductive fabric 11 of the laptop touch button tape is a non-woven conductive fabric. This non-woven conductive fabric has good conductivity and shielding properties.

[0029] like Figure 1 As shown, in one embodiment, both the first release film 13 and the second release film 15 of the laptop touch button tape are transparent release films. This arrangement facilitates visual inspection and also improves aesthetics.

[0030] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
