Description
Technical Field
The invention relates to the technical field of combination of injection molding and an antenna, in particular to a rear cover and antenna integrated part and a manufacturing method thereof.
Background
With the advent of the 5G era, the number of antennas in smart terminals such as smart phones is increasing. In the past, FPC antennas are all adhered to the inner surface of a rear cover, and as the number of antennas increases, in order to increase the antenna clear space, an antenna engineer needs to adhere a plurality of FPC antennas to the outer surface of the rear cover, where the rear cover refers to an external appearance piece of a smart terminal, and the rear cover plays a role of structurally supporting and bearing the antennas on one hand, and also plays a role of beautifying the external appearance of the smart terminal on the other hand, that is, the FPC antenna patterns on the outer surface of the rear cover need to be shielded through surface treatment, and a satisfactory external appearance effect is achieved.
In addition, both LDS and LAP techniques can etch and chemically plate multiple antennas on the outer surface of the plastic rear cover. However, the LDS technology requires a special modified plastic material to be used for injection molding the rear cover, and the modified plastic material is expensive and brittle, so the mechanical strength of the rear cover injection molded by the modified plastic material is poor. The LAP technique disclosed in patent 201410146680.8 is an LDS upgrading technique, and can be performed by using a common plastic material to mold a rear cover, then performing laser roughening and chemical activation, and then performing special chemical plating on the plastic rear cover to form a three-dimensional circuit diagram serving as an antenna. The LAP technology can be used for laser carving and chemically plating the antenna on other nonmetal back covers such as glass, ceramics and the like.
In order to beautify the appearance surface of the intelligent terminal, after laser etching, chemical plating of an LAP antenna or an LDS antenna is performed on the appearance surface of the rear cover, the antenna pattern on the outer surface of the rear cover also needs to be shielded through surface treatment. The LAP antenna or the LDS antenna is made of a metal material, the surface characteristics of the LAP antenna or the LDS antenna are different from those of the non-metal material of the rear cover, the antenna pattern is shielded, and a satisfactory appearance effect can be achieved only by performing surface treatment of repeatedly spraying, curing and polishing, wherein the polishing process may also polish the antenna. Therefore, if the outer surface of the back cover is subjected to laser etching, chemical plating of the LAP antenna or the LDS antenna and shielding, and a satisfactory appearance effect is achieved, the manufacturing process period is long, the yield is low, and the manufacturing cost is high.
In summary, an antenna engineer needs to fabricate a plurality of antennas on the outer surface of the rear cover of the smart terminal, however, it is still difficult in the art how to adopt the conventional surface treatment technology to shield the antenna pattern and achieve a satisfactory appearance.
