preparation example Construction

[0027] (3) In the preparation method of the silver-plated LDS antenna of the present invention, only two steps are required, the preparation process is simple, and the process of the first electroless plating and the second electroless plating does not need to add cyanide and does not need additional rinsing steps, while the gold coating in the coating structure of copper coating, nickel coating and gold coating in the prior art needs to add cyanide and a rinsing step must be set, which has the advantages of saving raw materials and reducing costs.

[0028] Further, the thickness of the second coating layer is 0.1-1 μm.

[0029] Further, the thickness of the second coating layer is 0.5-1 μm.

[0030] It can be seen from the above description that the thickness of the second silver plating layer can be designed according to actual needs. Preferably, it can be set to 0.1-1 μm, more preferably, it can be set to 0.5-1 μm, which can further ensure good electrical conductivity.

Abstract

The invention relates to an LDS antenna with silver coatings. The LDS antenna comprises an antenna element and the coatings. The coatings are composed of the first coating and the second coating. The first coating is a silver coating or a copper coating, and the second coating is a silver coating. The first coating is arranged on the surface of the antenna element, and the second coating is arranged on the surface of the first coating. The invention further relates to a manufacturing method of the LDS antenna with the silver coatings. The LDS antenna with the silver coatings and the manufacturing method of the LDS antenna have the beneficial effects that the performance of the antenna can be improved; safety, better electrical conductivity and the better anti-corrosion property are achieved; welding can be achieved; raw materials are saved; and the total cost is low.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a silver-coated LDS antenna and a manufacturing method thereof. Background technique [0002] At present, the antennas manufactured by LDS (Laser Direct Structured) laser direct structuring technology all use electroless Cu, Ni and Au layers as conductors. As a good conductor, Cu is widely used in other electronic and electrical engineering fields besides antennas. But Cu has poor corrosion resistance, especially in humid or other harsh environments. In order to avoid corrosion (which easily leads to performance degradation and poor visual effects), the Cu surface needs eg nickel plating as a protective layer. The Ni layer is not only used to prevent Cu corrosion, but also to block subsequent Au migration to the Cu layer. However, because Ni is carcinogenic in contact with human skin, it is included in the national list of restricted materials, so it is necessary to avoid t...
