By the laser irradiation ink lay, make the organic substance gasification in printing ink, expose the chemical plating active material, form on the surface of glass back of the body screen or coloured prime coat the antenna pattern that the chemical plating active material consists of, thereby follow-uply can carry out chemical plating on this chemical plating active material surface; In fact, activate by laser, can make the chemical plating active material be reduced into metal simple-substance, the catalyst that these metal simple-substances plate as subsequent chemistry, thus can carry out chemical plating.
In step 4, but carry out electroless copper on the surface of described chemical plating activating area, form the copper facing antenna stack on glass back of the body screen.
the electroless copper plating method that described method of carrying out electroless copper is commonly used for those skilled in the art, but the chemical plating active material that described chemical plating activating area exposes, after chemical bronze plating liquid contacts, can promote the copper ion generation reduction reaction in chemical plating fluid, generate metallic copper, be wrapped in the chemical plating active material surperficial, and be connected to each other the copper coating that forms one deck densification, thereby the chemical plating activating area (the antenna pattern zone that the chemical plating active material consists of) on glass back of the body screen or coloured prime coat surface forms the copper facing antenna stack fast, the thickness of described copper facing antenna stack is 28-30 μ m.
Preferably, preparation method of the present invention also comprises step 5, and described step 5 is the chemical nickel plating on surface at the copper facing antenna stack, forms nickel coating, and the thickness of described nickel coating is 0.5-1 μ m.
The method of the chemical nickel plating that the method for described chemical nickel plating is commonly used for those skilled in the art at the chemical nickel plating on surface of copper facing antenna stack, can prevent that the copper facing antenna stack is oxidized.
The various plating solutions that the chemical bronze plating liquid that adopts, chemical nickel-plating liquid all can adopt those skilled in the art to commonly use.For example, described chemical bronze plating liquid contains mantoquita and reducing agent, and the pH value is 12-13, and described reducing agent can be reduced to copper simple substance with copper ion in mantoquita, and reducing agent can be one or more in glyoxalic acid, hydrazine and inferior sodium phosphate.Described electroless copper yet can directly adopt disclosed copper plating bath in prior art, " sufacing " in December, 2002 for example, the interim disclosed a kind of plating solution of the 31st volume the 6th: CuSO
45H
2O 0.14mol/L, Na
2EDTA2H
2O
20.14mol/L, potassium ferrocyanide 10mg/L, 2,2 '-bipyridine 10mg/L, glyoxalic acid (HCOCOOH) 0.10mol/L, the copper plating bath temperature is 55-60 ℃, and with NaOH or H
2SO
4The pH value of regulating plating solution is 12-13.Chemical nickel plating also can adopt nickel-plating liquid of the prior art, for example it consists of: nickelous sulfate: 23g/l-25 g/l-, inferior sodium phosphate: 18g/l-20 g/l-, lactic acid: 18 g/l--20g/l, malic acid: 12 g/l--15g/l, regulating pH with NaOH is 4-5.2, and the temperature of nickel-plating liquid is: 85-90 ℃.
In the present invention, the time of electroless copper or chemical nickel plating is restriction not.Under preferable case, the time of electroless copper is 10-240 minute; The time of chemical nickel plating is 8-15 minute.
Make the mobile phone back of the body screen with antenna by above-mentioned preparation method, described mobile phone with antenna is carried on the back screen and is comprised glass back of the body screen and be formed at the antenna that the described glass back of the body shields, and described antenna is the copper facing antenna.In the preferred case, do not manifest glass back of the body screen in order to make the copper facing antenna, affect the aesthetic property of glass back of the body screen, also be coated with coloured prime coat on described glass back of the body screen, described copper facing dwi hastasana is formed on described coloured prime coat.In preferred situation, in order to protect the copper facing antenna, avoid the oxidation of copper facing antenna, also plate on described copper facing antenna and be provided with nickel coating.
In sum, but the present invention is by shielding according to designed antenna pattern silk screen printing metalization ink at the glass back of the body, then adopt energy beam to carry out radiation to described ink lay, expose the chemical plating active material, these chemical plating active materials can carry out chemical plating as the catalyst of subsequent chemistry plating, thereby realized making antenna on the surface that the glass back of the body shields, made mobile phone back of the body screen not only satisfy beyond the fashion degree and texture well of outward appearance, also satisfied functional need.
