Preferably:
Before carrying out described step S1, on described plastic casing surface, infiltrate one deck high-temperaure coating in advance; The softening temperature on described plastic casing surface refers to the softening temperature of described high-temperaure coating, and the fusing point on described plastic casing surface refers to the fusing point of described high-temperaure coating.
Shown in step S2 when metal dust is carried out to cladding sintering, to carried out the jet conservation treatment of inert gas by the position of cladding sintering.
Also comprise step S3: the antenna or the circuit that form are carried out to surface oxidation-resistant processing.
Before described step S1, in advance described metal dust being carried out to coated processing of binding agent applies so that metal dust surface is coated with binding agent and/or before spraying, metal dust is carried out to static.Wherein, can adopt static nozzle to spray, to apply static.
The particle diameter of described metal dust is 0.5-200nm.
The thickness of described pattern is 7-20 μ m.
Described inert gas is argon gas or nitrogen.
The present invention forms the pattern setting by shower nozzle metal injection powder, this pattern can be formed in plane, curved surface and the labyrinth gap, the back side on plastic casing, and then by the energy deposited metals powder of laser beam or electron beam, directly form antenna and circuit.Therefore, compared with prior art, the inventive method is convenient on shaped face, form specific antenna and circuit more, and method of the present invention also to have operation few, the beneficial effect that cost is low.
In preferred version:
Adopt the mode of the jet processing of inert gas to protect the position of cladding sintering, to avoid metal dust in cladding sintering process to be oxidized, this preferred version has advantage cheaply.
Adopt electrostatic powder shower nozzle can make metal dust surface band static, thereby can directly rely on electrostatic adherence on plastic casing surface, and without adding binding agent.Adopt the coated mode of binding agent can make the adhesive force of metal dust and plastic casing stronger, be conducive to by the jet processing of inert gas.
The metal dust of 0.5-200nm is conducive to adhesive force and the cladding sintering after spraying, spraying more.And the circuit that thickness is 7-20 μ m adopts method of the present invention to be prepared, its circuit performance performance is good.
There is gross distortion in excess Temperature when infiltration high-temperaure coating in plastic casing surface can be avoided frosting because of cladding sintering.
The specific embodiment
Below in conjunction with preferred embodiment the invention will be further described.
A manufacture method for antenna or circuit, for form antenna or circuit on plastic casing, comprises subordinate's step:
1) prepare for forming the metal dust of antenna or circuit, this metal dust can be gold, silver, bronze, fine copper or its alloy powder, and metal dust particle diameter is preferably: 0.5-200 nanometer.Preferably can carry out the coated processing of binding agent to metal dust, to be coated a layer binder on metal dust surface, this binding agent is preferably resin combination, mainly plays the cohesive force that strengthens metal dust and plastic casing.
2) plastic casing that need to form antenna or circuit infiltrates in high-temperature resistant coating, thereby forms one deck high-temperaure coating on plastic casing surface, thereby avoids plastic casing, in cladding sintering process, gross distortion occurs.For resistant to elevated temperatures plastics, can not carry out the processing of this step completely.
3) utilize shower nozzle by metal powder painting on plastic casing, thereby on plastic casing, form predetermined pattern, this pattern is the antenna that will form or the pattern of circuit.This step preferably adopts by the accurate three-dimensional motion shower nozzle of controlling by computer program and sprays, to obtain high-precision pattern; And in order to make metal dust there is higher adhesive force at frosting, more preferably adopt electrostatic powder shower nozzle metallisation end, for the metal dust that is coated with binding agent, also can adopt non-static nozzle to spray.The coating thickness of metal dust is preferably 7-20 μ m.
4) with coaxial laser bundle or electron beam to metal injection powder carry out cladding sintering make shown in metal dust close attachment shown in plastic casing surface form antenna or circuit, wherein the transient temperature of cladding sintering higher than the softening temperature on plastic casing surface lower than the fusing point on plastic casing surface.It should be noted that in the situation that not infiltrating high-temperaure coating, the softening temperature on plastic casing surface and fusing point are all softening temperature and fusing points of quantity case material; And in the situation that infiltration has high-temperaure coating, the softening temperature on plastic casing surface and fusing point are all softening temperature and fusing points of high-temperaure coating, now, the temperature of cladding sintering can be higher than the fusing point of plastic casing self material.In the time of cladding sintering, to carried out the jet processing of inert gas by the position of cladding sintering, air velocity is 0.1-0.25m/s, to avoid metal dust to react in airborne oxygen, oxidized.
