Abstract

The utility model provides a NFC antenna structure of line is walked to single face, relates to the NFC antenna. NFC antenna structure of line is walked to single face, including matrix material (1), lay printed circuit (2) and printing ink layer (3) of cover on printed circuit (2) that there are being matrix material (1) single face surface, the local extension of an avris that has matrix material (1) forms golden finger contact zone (11), printed circuit (2) are laid and are formed antenna coil (21), be provided with two golden finger positions in golden finger contact zone (11), a golden finger position is antenna coil initiating terminal (23), another golden finger position is antenna coil's end (24). The utility model discloses the degradable hangs down the production and the technology cost of product, further reduces the thickness of product, makes the product thinner, and the cost is lower.

Description

The NFC antenna structure of one side cabling

Technical field

The utility model relates to NFC antenna.

Background technology

Integrated circuit has been widely used the technical field at electronic communication, and is provided with very large improvement, and the appliance and electronic such as mobile phone is to frivolous future development for this reason.In order to adapt to mobile phone to frivolous future development, there is flexible PCB in currently available technology, flexible PCB is that the one made for base material with polyimides or polyester film has height reliability, flexible printed circuit, be called for short soft board or FPC, have the advantages that distribution density is high, lightweight, thickness is thin, bending property is good.The cabling of traditional two-sided FPC circuit is with the two-sided cabling of obverse and reverse, and cause FPC cost to increase, thickness cannot reduce, and further can not meet the needs of mobile phone development.

Summary of the invention

The purpose of this utility model is to provide the NFC antenna structure of the one side one side cabling that a kind of structure is simple, processing cost is low and more frivolous.

The utility model for the technical scheme achieving the above object adopted is: a kind of NFC antenna structure of one side cabling, the ink layer including gum base materials, be laid in the printed circuit of gum base materials monoplanar surface and cover on printed circuit; An avris local of gum base materials is had to extend to form golden finger contact zone, printed circuit is laid and is formed aerial coil, be provided with two golden finger positions in golden finger contact zone, a golden finger position is the initiating terminal of aerial coil, and another golden finger position is the end end of aerial coil.

Further, be less than by the coil line width between the initiating terminal of aerial coil and end end the coil line width being laid in other positions at golden finger contact zone place.

Further, the spacing between the initiating terminal and end end of golden finger contact zone place aerial coil is more than or equal to 3mm.

Further, gum base materials is had to be the flexible base, board being coated with gum described in.

Further, the thickness of gum base materials is had to be 0.10mm ± 0.02 described in.

The utility model can reduce production and the process costs of product, and reduce the thickness of product further, make product thinner, cost is lower.

Accompanying drawing explanation

Fig. 1 is the schematic diagram of the utility model preferred embodiment;

Fig. 2 is the generalized section of the utility model preferred embodiment.

Embodiment

Below in conjunction with drawings and Examples, the utility model is described in further detail:

As depicted in figs. 1 and 2, the NFC antenna structure of one side cabling, the ink layer 3 including gum base materials 1, be laid in the printed circuit 2 of gum base materials 1 monoplanar surface and cover on printed circuit 2; An avris local of gum base materials 1 is had to extend to form golden finger contact zone 11, printed circuit 2 is laid and is formed aerial coil 21, be provided with two golden finger positions in golden finger contact zone 11, a golden finger position is the initiating terminal 23 of aerial coil, and another golden finger position is the end end 24 of aerial coil.Designed by printed circuit 2 on the face having gum base materials 1, i.e. one side cabling, one side contact, effectively can reduce the thickness having matrix plate like this.

Be less than by the coil line width between the initiating terminal 23 of aerial coil 21 and end end 24 the coil line width being laid in other positions at golden finger contact zone 11 place.The width of printed circuit 2 is irregular, and the line width on described printed circuit 2 between two initiating terminals 23 be set up at golden finger position and end end 24 is thinner.

Spacing between the initiating terminal 23 and end end 24 of golden finger contact zone 11 place aerial coil 21 is more than or equal to 3mm, to ensure the setting by the coil line between the initiating terminal 23 of aerial coil 21 and end end 24.

Described have gum base materials 1 to be the flexible base, board being coated with gum, and gum is coated on the basis of existing flexible base, board.In the present embodiment, described in have the thickness of gum base materials 1 to be 0.10mm ± 0.02.
