High-frequency data transmission line and manufacturing method thereof

The invention discloses a high-frequency data transmission line and a manufacturing method thereof. The high-frequency data transmission line comprises a conductor part, the conductor part comprisingat least one first wire core group, the first wire core group comprising two wires, each wire comprising a first conductor formed by twisting seven bare copper wires with the diameter of 0.07 +/-0.008mm; a first insulating layer, coated on the first conductor, and the outer diameter of the first insulating layer is 0.50 +/-0.05 mm; a ground wire which is intertwisted with the two wires; aluminumfoil, coated on the two wires and the ground wire, the thickness of the aluminum foil being 13 +/-3 microns, and the width of the aluminum foil being 4 +/-1 mm; and a first wrapping tape layer, wrapped on the aluminum foil, and the winding pitch being 5 +/-0.5 mm. The high-frequency characteristic parameters of the transmission line are more optimized, and the transmission quality is high. 本发明公开了一种高频数据传输线及其制造方法，包括一导体部，该导体部包
