Problems solved by technology

A built-in mobile phone antenna needs to open two sets of molds, one set of antenna bracket molds and one set of metal shrapnel molds, the cost is high; in addition, the two parts need to be assembled with a hot-melt machine, the production efficiency is very low; and hot-melt The process is not well controlled, the hot melt temperature is not adjusted properly or the hot melt fixture is unstable, which will easily cause the failure of the hot melt column. If the operator is not skilled, it is easy to cause the deformation of the metal shrapnel, which will cause waste of materials in the production process and reduce the cost of mobile phones. Antenna production capacity

Abstract

The invention discloses a built-in mobile phone antenna, which comprises a bracket made from non-electroplated material, a radiation fin part made from electroplated material and a coating layer of the radiation fin part. Meanwhile, the invention further discloses a manufacturing method of the built-in mobile phone antenna. The built-in mobile phone antenna and the manufacturing method thereof reduce the production cost, improve the production efficiency, and remarkably improve the production capacity of the mobile phone antenna.

Description

technical field [0001] The invention relates to mobile phone antenna technology, in particular to a built-in mobile phone antenna and a manufacturing method thereof. Background technique [0002] Mobile phones are one of the most important mobile terminals currently used. After the rapid development in recent years, the replacement of mobile phones is very fast, and the competition among mobile phone manufacturers is becoming increasingly fierce. Low manufacturing cost and high production efficiency are extremely important competitiveness for mobile phone manufacturers. [0003] Mobile phone antenna is a very important part of mobile phone parts, which directly determines the quality of mobile phone call performance. The structure of a conventional built-in mobile phone antenna is shown in FIG. 1 , which is assembled by a plastic antenna bracket 110 and a metal shrapnel 120 through a heat-melt column 130 , wherein the metal shrapnel 120 is a kind of metal radiation sheet. ...
