Abstract

The invention discloses adhesive tape used as a shielding cover and application of the adhesive tape. When used as the shielding cover, the adhesive tape is excellent in shielding effect, thin and light. The adhesive tape comprises a release layer, a conductive adhesive layer, a fiber layer, a conductive adhesive layer, a conductive base body layer and an anti-oxidization conductive coating which are sequentially connected. The thickness of the adhesive tape is 0.03-0.3 mm. The conductive base body layer is a copper foil layer, an aluminum foil layer, a conductive fabric layer or a stainless steel layer. The thickness of the conductive base body layer is 0.005-0.25 mm. The adhesive tape can achieve electricity conductivity, shielding, grounding, anti-oxidization, heat conductivity and the like at the same time.

Description

technical field [0001] The invention relates to the field of shielding cover manufacture, in particular to an adhesive tape used as a shielding cover and its application. Background technique [0002] At present, the traditional shields on the market include: zinc-tin-nickel alloy shields, which are low in cost; nickel-nickel copper shields, which are made of good performance and easy to process; stainless steel shields, which are only used as covers. . In addition, the above-mentioned shielding cover also needs to be used together with a bracket, and the material of the bracket is zinc-tin-nickel alloy or nickel-nickel alloy. The installation of the above-mentioned bracket needs to be processed through processes such as bending, drilling, and installation. [0003] From the above analysis, it can be seen that the existing shielding cover has the following problems when used: thicker thickness, heavier weight, complicated processing, more manpower and material resources ar...
