Abstract
The invention discloses a kind of NFC antennas being printed on flexible circuit board, and frivolous weight is small, facilitate fixed and occupy little space, further improve production efficiency, reduce production cost.
Description
Technical field
The present invention relates to wireless charging field, in particular to a kind of NFC antenna.
Background technique
Wireless charger refers to the charger being connected on the terminal device for needing to charge without traditional charging power cord,
Using newest wireless charging technology, by using the magnetic field transmission electric energy generated between coil, and NFC (Near Field
Communication, near field communication (NFC)) it is the bridge for connecting charging base station and equipment, it is a kind of contactless knowledge
It is logical can to carry out near radio between mobile device, consumer electronics product, PC and smart control tool for other and interconnection technique
Letter.
NFC make to charge base station and equipment realizes that non-contact lower information identifies, wireless charger is activated to start to fill to equipment
Electricity, NFC are made of NFC module and NFC antenna.NFC antenna generally by the circuit coil of coiling/printing/etch process production with
The Ferrite Material of anti-interference ability forms.Current NFC electric wire is all to be made on pcb board, and NFC antenna is made on PCB,
User is no longer satisfied to wireless charger in price, the higher requirement of the aspect of quality.
The major defect being currently, there are is：
1.PCB plate is using copper-clad laminate as substrate, to be fixed in wireless charger with certain thickness hard plate
Difficulty is high, needs specially to increase the fixed structures such as detent, occupied space is big and has loosening, the undesirable risk such as abnormal sound.
The weight of 2.PCB plate is generally large, especially when having higher weight requirement to wireless charging device, lightweight packages
Mitigation it is most important.
The signal needs of 3.NFC antenna are interacted with control module, need to be welded to connect on pcb board in production at present
Device, then be attached by other auxiliary materials with main module, a series of process of solder connector is in addition to reducing production efficiency, also
Increase additional cost.
Summary of the invention
The embodiment of the present invention is designed to provide a kind of NFC antenna, and frivolous weight is small, facilitates fixed and occupied space
It is small, production efficiency is further improved, production cost is reduced.
A kind of NFC antenna provided in an embodiment of the present invention, NFC antenna are printed on flexible circuit board.
Optionally, the NFC antenna is printed on the process on flexible circuit board and includes：Photosensitive dry film is attached to flexible substrate
Route that is upper or generating conducting after print photosensitive-ink, exposure, development, etching on substrate on flexible substrate, completes the NFC
Antenna is printed on the flexible circuit board 10
Optionally, the flexible circuit board is made of using polyimides or polyester film as substrate.
Optionally, the flexible circuit board is fixed on charging shell.
Optionally, the flexible circuit board is pasted on the charging shell.
Optionally, the flexible circuit board is using sticking double faced adhesive tape on the charging shell.
Optionally, the terminal that the flexible circuit board is drawn connects mainboard.
Optionally, the mainboard is equipped with charge coil.
Optionally, the connector being connected with the terminal that the flexible circuit board is drawn is additionally provided on the mainboard.
Therefore using the present embodiment technical solution, NFC antenna is made on the flexible circuit board due to using,
Weight of equipment is alleviated, facilitate fixed and is occupied little space, non-loosening and abnormal sound.Connect compared to being made on pcb board without increase
Device and its additional process process are connect, production efficiency is further improved, reduces production cost.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention without any creative labor, may be used also for those of ordinary skill in the art
To obtain other drawings based on these drawings.
Fig. 1 is a kind of NFC antenna structural schematic diagram provided by the invention；
Fig. 2 is another NFC antenna structural schematic diagram provided by the invention；
Fig. 3 is the third NFC antenna structural schematic diagram provided by the invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Embodiment：
The present embodiment provides a kind of NFC antenna, the NFC antenna A is printed on flexible circuit board 10, as shown in Figure 1, institute
Stating flexible circuit board 10 is to have height reliability, excellent pliability using polyimides or polyester film as one kind made of substrate
Printed circuit board.Photosensitive dry film is attached on flexible substrate when production, exposed, development is generated on substrate after etching and led
Logical route after bonding protective film, just realizes the process that the NFC antenna is printed onto the flexible circuit board 10.Specific mistake
Journey is as follows：Flexible polyester copper-clad plate substrate-patch photosensitive dry film or the continuous automatic exposure-imaging-etching-of print photosensitive-ink-
Film -- washing -- drying-quality inspection-packaging is moved back, the NFC antenna A is completed and is printed on flexible circuit board 10.
The flexible circuit board 10 is fixed on charging shell 20, as shown in Fig. 2, can be, but not limited to, the flexible electrical
Road plate 10 is pasted on the charging shell 20, such as the flexible circuit board 10 can be pasted onto described fill using double-sided adhesive 30
On electric shell 20.The terminal 11 that the flexible circuit board 10 is drawn connects mainboard 40, as shown in figure 3, the mainboard 40 is equipped with
Charge coil 50.The connector 60 being connected with the terminal 11 that the flexible circuit board 10 is drawn is additionally provided on the mainboard 40,
Realize the interaction of information.
The flexible circuit board has the characteristics that Distribution density is high, light-weight, thickness is thin, bending is good, in charging equipment
In, NFC antenna is made on the flexible circuit board, quality is frivolous, alleviates weight of equipment, facilitates fixed and occupied space
It is small, non-loosening and abnormal sound.Compared to being made on pcb board without connector and its additional process process is increased, further improve
Production efficiency reduces production cost.
Embodiments described above does not constitute the restriction to the technical solution protection scope.It is any in above-mentioned implementation
Made modifications, equivalent substitutions and improvements etc., should be included in the protection model of the technical solution within the spirit and principle of mode
Within enclosing.
