Detailed Description

To further explain the technical means and effects of the present invention adopted to achieve the intended purpose, the following detailed description of the embodiments, structural features and effects of the present invention will be made with reference to the accompanying drawings and examples.

As shown in figure 1, the weldable metalized injection-molded antenna oscillator comprises an oscillator body 1, wherein the oscillator body 1 is made of high-temperature plastics such as PPS, PEI, PEEK and LCP through injection molding, and a chemical plating layer 2, an electroplating signal layer 3 and a protective layer 4 are sequentially arranged on the oscillator body 1.

The surface of the vibrator body 1 is roughened by the existing chemical or physical method, so that the electroplating binding force is improved; the roughness can be preferably controlled between Ra1.6-6.3 according to the surface finish requirement of the product.

The chemical plating layer 2 is formed by the existing chemical deposition method for metal nickel or metal copper, and the thickness of the chemical plating layer 2 is 1-2 um.

The plating signal layer 3 is a metal plating layer, the plating metal and the plating color can be selected as required, such as one or a mixture of two of copper, tin, silver, gold, etc., the plating signal layer 3 is used for transmitting or reflecting electric signals and can be welded, and the thickness of the plating signal layer 3 is preferably 10-25 um.

The protective layer 4 is a protective film formed by passivating the electroplated signal layer 3, and the thickness of the protective film is 0.3-0.7 um.

After the surface roughening process treatment, the surface bonding force and the rapid deposition capability of the vibrator body 1 are increased, then the chemical plating is carried out, a copper layer or a nickel layer is rapidly deposited on the surface of the vibrator body 1, so that the surface of the vibrator body 1 has the conductive capability, and then metal layers with extremely strong conductive capabilities, such as copper, silver, gold, tin and the like, are electroplated on the surface of the vibrator body 1, so that the electroplating of a signal transmission metal layer on the surface of the vibrator body 1 is completed, the metal and the color of the electroplated layer can be customized, and the communication equipment assembly is mostly welding, so that the signal metal layer needs to have extremely strong conductive capability and also needs welding capability, and more silver and tin are generally selected; in order to prevent the product from generating problems of color change, oxidation, corrosion and the like on the surface of the product under severe conditions, passivation reaction treatment of an electroplating signal layer or other special conductive protective agent treatment is also needed to form a protective layer 4, the structural vibrator has super-strong conductive capability, and meanwhile, the surface has corrosion resistance, can adapt to any environment application, can realize local conduction, and can be welded and assembled with any other electronic part.
