Description
Technical field
The present invention relates to the antenna technical field in radio communication terminal, more particularly to a kind of manufacture method of all-metal mobile phone NFC antenna.
Background technology
The mobile terminals such as smart mobile phone, PDA, mobile PC hereinafter referred to as " mobile phone ".Mobile phone with NFC function can be used as RFID passive labels, be may also act as RFID reader and used.With the popularization of the applications such as mobile payment, NFC function is by the standard configuration as smart mobile phone.NFC antenna is generally served as by wire coil, and wire coil can print on FPC, also can be using LDS fabrication techniques on plastic parts.At present, mobile phone built in NFC antenna has following two processing methods：NFC antenna is arranged on the plastic cement of cell phone rear cover by first method；Second method such as village field science and technology patent CN102405556B proposed a through hole and one are opened on shell after metal from through hole to metal after shell edge gap, the gap has cut off original vortex being completely reversed produced after metal on shell so that the vortex becomes the effective vortex that to antenna has positive effect in the same direction with antenna current.The NFC antenna area that first method needs is larger, can not be realized on all-metal fuselage.Although second method solves shielding action of the shell to NFC antenna after metal by the method for perforate and gap, the through hole and gap opened have impact on the integrality of shell after metal, destroy the aesthetic feeling and intensity of metal fuselage.
Such as application publication number is CN104993216A, entitled《NFC antenna structure for metal back cover mobile phone》Patent of invention, it is provided with its mobile phone metal back cover for blocking the spill grooving that is vortexed in mobile phone metal back cover and perforate for configuring camera, NFC antenna is communicated by being realized between spill grooving and perforate and external reader antenna using magnetic field coupling, and its spill grooving is made up of two transversal slottings and two vertical flutings.The invention needs NFC antenna being arranged near camera, and design limitations are big.
The content of the invention
The present invention is intended to provide a kind of manufacture method of all-metal mobile phone NFC antenna, this method can also realize NFC antenna function without NFC antenna is arranged on around metal back cover camera lens hole on all-metal mobile phone.A kind of manufacture method of all-metal mobile phone NFC antenna, including the step that following order is performed are gathered：
S1：Make endless metal frame；
S2：Make metal back cover；
S3：Metal edge frame is connected as a single entity with metal back cover by in-mould injection, ring plastic cement part is formed between endless metal frame and metal back cover；
S4：NFC antenna coil is made on the ring plastic cement part of the poly- S3 formation of the step；
S5：Fitted in the poly- S4 of the step behind NFC antenna coil ferrite layer.
Preferably, the endless metal frame can be cut off, select its top independent metal edge strip as miniature antenna radiant body, selection its underpart independent metal edge strip includes diversity antenna, slave antenna, GPS+WiFi antennas and BT antennas as primary antenna radiant body, the miniature antenna.
Preferably, on the endless metal frame it is cleavable go out USB holes, loudspeaker acoustic aperture, earphone jack, Mike's pickup hole etc..
Preferably, in the metal back cover it is cleavable go out camera lens hole, flash lamp aperture etc..
Preferably, the in-mould injection is using nanometer injection in mould, to ensure structural strength.
Preferably, the NFC antenna coil of the step S4, be can print on FPC, also can be using LDS fabrication techniques on ring plastic cement part, and coil turn inductance value as needed is determined.
Preferably, the ferrite layer is annular, and the NFC antenna coil described in step S4 is completely covered.
Preferably, the ferrite layer can make together with FPC coils, can also be fabricated separately, and be fitted in behind LDS coils.
The advantage of the invention is that：1）Without the embedded large area plastic parts in metal back cover, you can realize NFC antenna function on all-metal mobile phone.2）NFC antenna coil need not be arranged near camera lens hole, without cutting out the vertical line of rabbet joint at camera aperture.3）Metal back cover need not be partitioned into three sections, and a narrow annulus need to be only gone out along bonnet edge cuts, and independent metal frame members can be used for other antennas.
Brief description of the drawings
Fig. 1 is an embodiment of the present invention mobile phone metal shell floor map.
Wherein, 101 endless metal frame is represented；102 represent metal back cover；103 represent ring plastic cement part；104 represent NFC antenna coil；105 represent NFC antenna contact；106 represent metal primary antenna；107 represent metal miniature antenna.
Embodiment
The invention discloses a kind of manufacture method of all-metal mobile phone NFC antenna.
Below in conjunction with accompanying drawing, the technical scheme in the present invention is clearly and completely described.Described is only a part of embodiment of the invention, rather than embodiment whole.Based on the embodiment of the present invention, all other embodiment that those of ordinary skill in the art are obtained on the premise of creative work is not made belongs to the scope of protection of the invention.
As shown in figure 1, illustrating a kind of manufacture method of all-metal mobile phone NFC antenna, particular content comprises the following steps：
The first step, makes endless metal frame 101.The two ends of endless metal frame 101 are cut off, and the top independent metal edge strip of selection endless metal frame 101 selects 101 bottom independent metal edge strips as the radiant body or one part of metal primary antenna 106 as the radiant body or one part of metal miniature antenna 107.The miniature antenna includes diversity antenna, slave antenna, GPS+WiFi antennas and BT antennas.On the endless metal frame also it is cleavable go out USB holes, loudspeaker acoustic aperture, earphone jack, Mike's pickup hole etc..
Second step, makes metal back cover 102.Camera lens hole, flash lamp aperture etc. are cut out in metal back cover 102, it is not necessary to carry out special disposal for antenna.
Endless metal frame 101, is connected as a single entity, ring plastic cement part 103 is formed between endless metal frame 101 and metal back cover 102 by the 3rd step by nanometer injection in mould with metal back cover 102.
