Ultrathin EMI electromagnetic shielding adhesive tape

Abstract

The invention discloses ultrathin EMI electromagnetic shielding adhesive tape. The adhesive tape includes a tape body, an optical PET layer, a buffer layer and a copper coil layer. The optical PET layer is arranged on one side of the interior of the tape body, a heat conducting layer is installed at the portion, on one side of the optical PET layer, of the interior of the tape body, and the bufferlayer is installed on the side, where the heat conducting layer is away from the optical PET layer, of the interior of the tape body; buffer strips are uniformly installed in the buffer layer, a resin thin film layer is installed on the side, where the buffer layer is away from the heat conducting layer, of the interior of the tape body, and an anti-corrosion layer is installed on the side, wherethe resin thin film layer is away from the buffer layer, of the interior of the tape body. By installing the copper coil layer at the portion, on one side of a first bonding layer, of the tape body,forming second saw teeth on both sides of the copper coil layer and installing the resin thin film layer in the tape body, the surface roughness and the contact surface can be effectively increased, the bonding force among the copper coil layer, an aluminum coil layer and a glue layer is enhanced, the structural stability of the adhesive tape is ensured, and meanwhile, the electromagnetic shielding capability of the adhesive tape is improved.

Description

technical field [0001] The invention relates to the technical field of electromagnetic shielding tapes, in particular to an ultra-thin EMI electromagnetic shielding tape. Background technique [0002] With the advent of the digital age, electronic products such as laptops, handheld computers, mobile phones, and copiers have entered thousands of households. However, these products will generate noise due to high-frequency electromagnetic interference, which will affect the quality of use. If the human body is exposed to strong electromagnetic fields for a long time If the environment is low, it may be susceptible to cancer, so it is imperative to prevent electromagnetic interference. Shielding is to isolate the metal between two spatial regions to control the induction of electric fields, magnetic fields and electromagnetic waves from one region to another. and radiation. [0003] Copper foil is a kind of high-performance electromagnetic shielding material. In the prior art,...
