[0002] Copper foil tape is a metal tape mainly used for electromagnetic shielding, which is divided into electrical signal shielding and magnetic signal shielding. Electrical signal shielding mainly relies on the excellent electrical conductivity of copper itself, while magnetic shielding requires the conductive material "nickel" on the adhesive surface of copper foil tape to achieve the magnetic shielding effect. Therefore, it is widely used in mobile phones, laptops and other digital products.

[0003] According to a double-sided conductive copper foil tape disclosed in Chinese patent CN202023241847.9, the application provides a convenient winding point by setting an inner circle wheel and an outer circular edge, and the serrated edge can be used conveniently at the beginning. The anti-tear protective film can prevent it from being easily torn during use, and the easy-tear line can be used in sections and easily torn at the required nodes. The existing double-sided conductive copper foil tape is easy to cut by setting the easy-tear line, but the existing easy-tear lines are basically equidistantly distributed, and the tape lengths between the two sets of easy-tear lines are the same. Therefore, it is impossible to cut tapes of different lengths according to actual needs, which brings trouble to use.
