[0002] With the rapid development of the information age, laptops have become widely used, bringing great convenience to people's lives, studies, and work. In the manufacturing process of laptop motherboards, conductive foam is typically installed. However, traditional conductive foam is omnidirectionally conductive and cannot achieve localized conductivity, limiting its further application and development in electronic devices. Utility Model Content

[0006] Furthermore, the density of the polyurethane foam is 50±5 kg / m³. 3 The surface rigidity is 90±5° and the thickness is 5.32±0.6mm.

[0007] Furthermore, the polyurethane foam has a tensile strength ≥0.085 MPa, a breaking load ≥35 N, a breaking elongation ≥130%, an indentation load deflection of 25% ≥80 N, an indentation load deflection of 40% ≥100 N, an indentation load deflection of 65% ≥150 N, and a permanent compression set ≤8%.

[0008] Furthermore, the conductive cloth is a single-sided conductive cloth with built-in hot melt adhesive.

[0009] Furthermore, the conductive cloth surface is provided with a layer of black copper-nickel conductive coating.

[0010] Furthermore, the conductive cloth has a thickness of 0.05±0.015mm, a surface resistivity of <0.07Ω / sq, and a planar on-resistance of <0.1Ω.

[0011] Furthermore, the conductive double-sided adhesive has a thickness of 0.05±0.005mm, a 180-degree peel force of >1300g / 25mm, and a vertical conduction resistance of <0.05Ω.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This utility model discloses an antioxidant locally conductive cushioning foam. The foam contains polyurethane foam, which provides shock absorption and cushioning. A conductive cloth is wrapped around the polyurethane foam, and Mylar tape of a specific shape is placed on the outside of the conductive cloth to partially shield the conductive cloth. Only the hollowed-out areas expose the conductive cloth, creating local conductivity while the rest is insulated, preventing the product from being subjected to unnecessary electromagnetic interference. Conductive double-sided adhesive is also placed on the outside of the conductive cloth, providing both bonding and conductivity. It is suitable for laptop motherboards and can provide multiple functions such as anti-oxidation, local conductivity, shock absorption, cushioning, and shielding. The overall structure is simple, the manufacturing cost is low, and it has great potential for widespread application. Attached Figure Description
