Description
Technical field
The present invention relates to antenna technical field more particularly to a kind of production methods of NFC antenna.
Background technique
NFC antenna is generally made of ferrite structure and FPC, and the one side of ferrite structure needs to carry out single-sided back-adhesive will
Ferrite powder is fixed, and the another side of ferrite structure needs to carry out two-sided gum to bond together with FPC.It is existing
Ferrite structure and FPC are die-cut to the shape needed by some NFC antennas respectively in production, first, then again carry out the two
Assembling, when assembling, are difficult to be accurately positioned, low efficiency, and finished product yield is low.When needing NFC antenna being made into mounting structure
When, the two-sided gum part in ferrite structure will not carry out be bonded, exposed back-adhesive surface with FPC completely and be likely to making
The impurity such as dust are stained in journey, it will seriously affect the later period assembling of NFC antenna.
Summary of the invention
The technical problems to be solved by the present invention are: a kind of production method of NFC antenna is provided, high production efficiency, and after
Phase is easily assembled to.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention are as follows:
A kind of production method of NFC antenna carries out gum to the ferrite for making NFC antenna, makes ferritic one
Single side glue-line is formed on side, is formed layers of two-sided on ferritic another side, is obtained ferrite structure；In the ferrite
Protective film is pasted in the layers of two-sided of structure, is then pressed in the region that the layers of two-sided does not paste protective film for making
The FPC of NFC antenna obtains antenna composite construction；The antenna composite construction is punched out, obtain at least two it is described
NFC antenna.
The beneficial effects of the present invention are: before pressing FPC protective film is pasted in layers of two-sided, can prevent in life
It produces and is stained with the impurity such as dust in manufacturing process, the later period tears protective film off when mounting；First FPC and ferrite structure are pressed
It is punched out again afterwards, can be with the multiple NFC antennas of one-pass molding, high production efficiency, and do not need to be aligned one by one, product is good
Rate is high.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that protective film is pasted in ferrite structure of the embodiment of the present invention one；
Fig. 2 is the structural schematic diagram of the NFC antenna of the embodiment of the present invention one.
Label declaration:
1, ferrite structure；2, protective film；3, NFC antenna.
Specific embodiment
To explain the technical content, the achieved purpose and the effect of the present invention in detail, below in conjunction with embodiment and cooperate attached
Figure is explained.
The most critical design of the present invention is: first will FPC and ferrite structure pressing after be punched out again, can once at
The multiple NFC antennas of type, high production efficiency.
Fig. 1 and Fig. 2 is please referred to, a kind of production method of NFC antenna carries out the ferrite for making NFC antenna
Gum makes to form single side glue-line on ferritic one side, forms layers of two-sided on ferritic another side, obtain ferrite
Structure 1；Protective film 2 is pasted in the layers of two-sided of the ferrite structure 1, does not then paste protective film in the layers of two-sided
2 region presses the FPC for making NFC antenna, obtains antenna composite construction；The antenna composite construction is punched out,
Obtain at least two NFC antenna 3.
As can be seen from the above description, the beneficial effects of the present invention are: before pressing FPC protection is pasted in layers of two-sided
Film can prevent from being stained with the impurity such as dust during manufacturing, and the later period tears protective film off when mounting；First by FPC
It is punched out again with after ferrite structure pressing, can be with the multiple NFC antennas of one-pass molding, high production efficiency, and do not need one
One is aligned, and product yield is high.
Further, location hole is successively made in the ferrite structure 1 before pasting protective film 2 and keeps away position and is opened
Window.
Seen from the above description, production location hole is convenient for being positioned with FPC and protective film.
Further, location hole is made on the FPC and protective film respectively before pasting protective film.
Further, the spacing between the two neighboring NFC antenna 3 is 1.5~2mm.
Seen from the above description, there is a certain distance, convenient for punching between two neighboring NFC antenna.
Further, the protective film 2 with a thickness of 0.01~0.03mm.
Seen from the above description, the thinner thickness of protective film will not influence the overall structure and assembling of NFC antenna 3.
Further, the material of the protective film 2 is PET or release paper.
Seen from the above description, the material of protective film, which can according to need, is selected.
Please refer to Fig. 1 and Fig. 2, the embodiment of the present invention one are as follows:
A kind of production method of NFC antenna, comprising: gum is carried out to the ferrite for making NFC antenna, makes ferrite
One side on form single side glue-line, form layers of two-sided on ferritic another side, obtain ferrite structure 1.Exist respectively
Location hole is made on the ferrite structure 1, FPC and protective film 2, then production keeps away position windowing in ferrite structure 1.Such as figure
Shown in 1, paste protective film 2 in the layers of two-sided of the ferrite structure 1, the protective film 2 with a thickness of 0.01~
0.03mm, preferably 0.025mm, the material of the protective film 2 are PET or release paper.Then guarantor is not pasted in the layers of two-sided
The region of cuticula 2 presses the FPC for making NFC antenna, obtains antenna composite construction.As shown in Fig. 2, compound to the antenna
Structure is punched out, and obtains at least two NFC antenna 3, and the spacing between the two neighboring NFC antenna 3 is 1.5
~2mm.In the present embodiment, can produce once multiple NFC antennas 3 according to specific needs, and production efficiency greatly improves.
In conclusion a kind of production method of NFC antenna provided by the invention, it can be raw with the multiple NFC antennas of one-pass molding
It produces high-efficient, and does not need to be aligned one by one, product yield is high；Obtained NFC antenna is mounted convenient for the later period, is assembled
It is convenient.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalents made by bright specification and accompanying drawing content are applied directly or indirectly in relevant technical field, similarly include
