Embodiment 1-4 and comparative example 1

[0059] with the help of figure 2 and 3 The extrusion device shown uses a single wire comprising a copper alloy (silver content: about 10%) reinforced with in-situ silver fibers and has an outer diameter of 30 μm as an internal conductor, and uses a composition and MFR ( g / 10min) polymer alloy or ABS resin as the material of the dielectric layer to make a coated electric wire with an outer diameter of about 80 μm. The peripheral surface of the resulting coated electric wire was etched using hydrochloric acid to grant a catalyst. The catalyst was activated, and a thin film barrier layer (metal coating) having a thickness of 2 μm and including copper was formed on the activated peripheral surface by electroless plating. pass Figure 4 The shown die was polished to form a protective coating including polyurethane on the periphery of the coated electric wire having the film shield formed therein to obtain an ultra-fine coaxial cable having an outer diameter of about 100 μm. Th...

Abstract

An ultrathin coaxial cable comprises: inside conductor; dielectric layer at periphery of the inside conductor, comprising polyamide and polymer alloy of ABS resin; film shielding layer at the periphery of the dielectirc layer; protecting coating layer at the periphery of the film shielding layer. The invention also provides a method for manufacturing the ultrathin coaxial cable, comprising the following steps: forming the dielectirc layer including polymer alloy at periphery of the inside conductor through extruding; etching the dielectric layer's surface with hydrochloric acid, phosphoric acid, sulphuric acid or organic acid; treating the periphery of the etched dielectirc layer in order to supply catalyzer; activating the catalyzer; forming the film shielding layer at the periphery of the dielectirc layer by chemical plating or the combination of chemical plating and electric plating, the said dielectirc layer has activated catalyzer; forming protecting coating layer at the periphery of the film shielding layer.

Description

technical field [0001] The present invention relates to an ultra-thin coaxial cable, and a method of manufacturing the same. More particularly, the present invention relates to an ultra-fine coaxial cable which is excellent in flexural strength and electromagnetic shielding characteristics, and therefore, can be used, for example, in industrial robots, especially in information communication equipment such as notebook PCs and A cable for transmitting electric signals for control etc. through a movable part (for example, a bent part) in a mobile phone; and a method of manufacturing the ultra-fine coaxial cable. Background technique [0002] In recent years, for example, miniaturization, weight reduction, and complication of electronic equipment have rapidly progressed in the field of the electronics industry. In order to keep pace with these trends, cables connected to electronic devices are required to be ultra-thin, space-saving, and the like. [0003] A flexible printed ...
