Preparation method of copper foil antenna

Abstract

The invention relates to a preparation method of copper foil antenna and comprises the following steps: first, designing the shapes and dimensions of die cutting tools of materials according to requirements; preparing raw materials of double faced adhesive tape, PET, copper foil, PC, transparent PET protective film and exhausting film, respectively preparing tools for die cutting PC, copper foil,transparent PET and main material mesh cloth and installing on the tool seats corresponding to the used die cutting devices, respectively laminating and die cutting the raw material of PC, copper foil, transparent PET and mesh cloth to obtain a tape coiling group winded with initially shaped half-finished products of PC, copper foil and transparent PET and directly obtain the monomer half-finished product of mesh cloth; then placing the tape coiling group of the half-finished products of PC, copper foil and transparent PET on slicing machines to slicing; sticking PC, copper foil and transparent PET sequentially on fixed position on a jointed board to obtain the finally finished product of copper foil antenna. The method can replace the conventional methods to manufacture antennae, can satisfy the requirement on internally installed antennae in mobile phones well, can realize mass production, and opens up a new field for preparation technology of antennae.

Description

technical field [0001] The invention relates to a preparation method of a copper foil antenna. Background technique [0002] Traditional antennas generally use etched antennas or printed antennas, and the production of such antennas requires screen printing equipment and etching equipment. The production process will cause great pollution to the environment. And due to the limitation of its process method, it needs to invest a lot of manpower and equipment resources for mass production, and it is also difficult to manufacture antennas that meet high performance (such as built-in antennas for mobile phones), and the scrap rate is high, and the production efficiency is low. [0003] To solve this problem, it is necessary to develop a new type of antenna. Therefore, researchers have begun to devote themselves to the development of a new type of copper foil antenna. [0004] High-performance conductive copper foil has excellent adhesiveness, moisture resistance, corrosion resi...

AI Technical Summary

Problems solved by technology

However, the die-cutting needs to be reciprocated, and the efficiency is low; the die-cutting contact surface is large, the working pressure is unstable, the product forming stability is not good, and the product scrap rate is relatively high; the tool life is short

Most flat knives cannot be repaired and used repeatedly. Once damaged, they can only be scrapped, so the overall life is relatively short.
