Description
Technical field
It the utility model is related to antenna technical field, more particularly to a kind of LDS antenna structures.
Background technology
The manufacture craft of LDS (Laser Direct Structuring, laser direct forming) antenna structure generally requires
Three steps：Injection molding, Laser Processing and circuit pattern metallization.It can pass through laser carving on moulding using LDS technologies
Electroless copper is carried out afterwards and produces the various antenna patterns for meeting design requirement, and solid can be formed by the excellent conductive capability of copper
Circuit, this measure can greatly increase the space of product, reduce the quantity of component and the flexibility of assembling.But in copper conductive pattern
Making and use during, inevitably in hot and humid environment, copper-base is vulnerable to the corrosion of oxygen, enters
And have a strong impact on its various aspects of performance.Therefore, must in order to prevent the oxidation deactivation of copper conductive pattern, ensure its normal work
Surface deposition nickel coating must be carried out to it to improve decay resistance, when exposing in atmosphere self-passivation shape can occur for metallic nickel
The self-passivation film fine and close into one layer, so as to ensure that matrix is not continued oxidation, so possessing very outstanding corrosion resistance.
Deposition nickel coating can use electro-plating method and chemical plating method.For LDS antenna structures in nickel plating, usually plating is white
Nickel, and when the color of antenna holder is black, there can be larger aberration, at this time, it may be necessary to be carried out to antenna surface at melanism
Reason, to meet requirement of the client to appearance color.Production process can undoubtedly be increased by carrying out Darkening process, be unfavorable for improving production effect
Rate and cost-effective.
Utility model content
Technical problem to be solved in the utility model is：A kind of LDS days knots that need not carry out Darkening process are provided
Structure.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：
A kind of LDS antenna structures, including antenna holder, the antenna holder are provided with the copper wire layer stacked gradually and nickel plating
Layer, the nickel coating is black nickel dam.
Further, the thickness of the black nickel dam is 2-5 μm.
Further, the thickness of the copper wire layer is 10-18 μm.
Further, the black nickel dam includes nickeltin and/or nickel sulfide.
Further, the black nickel dam is deposited in copper wire layer by way of chemical plating.
Further, the black nickel dam includes nickel, zinc and sulphur.
The beneficial effects of the utility model are：The black coating nickel in copper wire layer, when the color of antenna holder is black, no
Need the later stage to carry out Darkening process to antenna holder and can reach the consistent requirement of appearance color, process can be saved, improve life
Efficiency is produced, it is cost-effective；And black nickel dam has the pore space structure of large area, aerial radiation area can be increased, improve antenna
Performance, it is also beneficial to increase area of dissipation during Antenna Operation, extension antenna service life.
Brief description of the drawings
Fig. 1 is the diagrammatic cross-section of the LDS antenna structures of the utility model embodiment one；
Label declaration：
1st, antenna holder；2nd, copper wire layer；3rd, black nickel dam.
Embodiment
For detailed description technology contents of the present utility model, the objects and the effects, below in conjunction with embodiment and match somebody with somebody
Accompanying drawing is closed to be explained.
The design of the utility model most critical is：In the surface black coating nickel dam of copper wire layer, it is not necessary to antenna is carried out black
Change is handled, and can greatly save process.
Fig. 1, a kind of LDS antenna structures, including antenna holder are refer to, the antenna holder is provided with the copper stacked gradually
Line layer and nickel coating, the nickel coating are black nickel dam.
It was found from foregoing description, the beneficial effects of the utility model are：The black coating nickel in copper wire layer, when antenna holder
When color is black, it is not necessary to which the later stage carries out Darkening process to antenna holder and can reach the consistent requirement of appearance color, can be with
Process is saved, improves production efficiency, it is cost-effective；And black nickel dam has the pore space structure of large area, antenna spoke can be increased
Area is penetrated, improves antenna performance, is also beneficial to increase area of dissipation during Antenna Operation, extension antenna service life.
Further, the thickness of the black nickel dam is 2-5 μm.
Seen from the above description, the thickness of black nickel dam can plate according to specific needs, unsuitable blocked up or excessively thin.
Further, the thickness of the copper wire layer is 10-18 μm.
Seen from the above description, the thickness of copper wire layer can be selected as needed.
Further, the black nickel dam includes nickeltin and/or nickel sulfide.
Further, the black nickel dam includes nickel, zinc and sulphur.
Seen from the above description, black nickel dam both can be the mixture of nickeltin and nickel sulfide, can be again collection nickel,
The coating that zinc, sulphur, organic matter are integrated.
Further, the black nickel dam is deposited in copper wire layer by way of chemical plating.
Fig. 1 is refer to, embodiment one of the present utility model is：
A kind of LDS antenna structures, the later stage can be avoided to carry out Darkening process to antenna, process can be saved.
As shown in figure 1, the LDS antenna structures include antenna holder 1, the antenna holder 1 is provided with what is stacked gradually
Copper wire layer 2 and black nickel dam 3.Preferably, the thickness of the copper wire layer 2 is 10-18 μm, and the thickness of the black nickel dam 3 is 2-5 μm.
Black nickel dam 3 both can be the mixture of nickeltin and nickel sulfide, can be the plating for integrating nickel, zinc, sulphur, organic matter again
Layer.In the present embodiment, black nickel dam 3 is the mixture of nickeltin and nickel sulfide.
In the present embodiment, the manufacturing process of LDS antenna structures is：
First, injection obtains antenna holder 1, after then laser carving goes out antenna pattern on antenna holder 1, chemical plating copper wire layer
2, copper wire layer 2 is washed successively after having plated, alkali cleaning oil removing, washing, acid pickling and rust removing, washing, antenna holder 1 is then immersed into plating
In the chemical plating fluid of black nickel, chemical plating fluid includes hypophosphites, nickel sulfate, potassium rhodanate and soluble pink salt, reaction generation nickel
Tin alloy and nickel sulfide are deposited in copper wire layer 2, and the nickel sulfide of generation makes nickel coating show as black.Carried out again after the completion of nickel plating
