Problems solved by technology

[0003] The above-mentioned process needs to disperse palladium ions in the plastic material (whether it is the place where the antenna is formed by default or the place where the antenna is not formed by default), so the amount of palladium is quite large, but palladium is a relatively expensive metal, so the material cost of this process is expensive
Furthermore, the stress characteristics (such as hardness, brittleness, elasticity, etc.) of plastic materials change after adding copper ions and palladium ions, so they cannot meet the needs of some industries. In addition, the above-mentioned process is only applicable to some specific types of plastic materials

Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] refer to figure 1 and figure 2 , the first preferred embodiment of the selective plating method for plastic parts of the present invention, first as shown in step S01, a plastic raw material and a laser sensitive additive 2 are mixed and injection molded to produce an electrically insulating part 100, which is electrically insulating The part 100 includes a plastic part 1 and a laser-sensitive additive 2 dispersed in the plastic part 1 . The plastic raw material can be ABS, PBT or PC, but not limited thereto. Laser-sensitive additive 2 (laser-sensitive additive) is commonly known as laser marking powder, laser powder, laser additive, photosensitizer or laser engraving powder, such as products produced by MERCK in Germany. ". Laser-sensitive additives can be titanium oxides (such as titanium dioxide (TiO 2 )), zinc sulfide (ZnS), calcium ...

Abstract

A method of depositing a metal layer on an electrically non-conductive plastic member includes: mixing a plastic material and a laser-sensitive additive to form a mixture, followed by injection molding the mixture to form an electrically non-conductive plastic member; irradiating a part of a surface of the electrically non-conductive plastic member with laser to engrave the electrically non-conductive plastic member so as to form a roughened region; forming an activating layer on the roughened region; and forming a metal layer on the activating layer on the roughened region of the electrically non-conductive plastic member. This method is suitable for making a housing for a mobile device.

Description

technical field [0001] The invention relates to a method for selective plating of plastic parts, in particular to a method for selective plating of plastic parts with relatively low production cost. The present invention also relates to a casing of a mobile communication device manufactured by the aforementioned method. Background technique [0002] The size of mobile communication devices is currently trending toward miniaturization. In order to reduce the volume of mobile communication devices, antennas of some mobile communication devices are currently formed on the surface of the back cover of the mobile communication device. One process method currently used to achieve this structural design is to mix copper ions and palladium ions with plastic raw materials and inject them to produce a plastic-based back cover, and then irradiate the predetermined area of ​​the back cover with a laser to inject the palladium into the back cover. Ions and copper ions are activated. Fi...
