Background technology
A kind of near-field coupling antenna of NFC antenna, because 13.56Mhz wavelength is very long, and reading/writing distance is very short, suitable coupled modes are magnetic Field Couplings, coil is suitable coupled modes, consumer product due to mobile phone and so on has very high appearance requirement, therefore antenna generally needs built-in, but after built-in antenna, antenna just must press close to mainboard or battery (all containing metallic conductor composition), the consequence of such design is, antenna can produce eddy current to weaken the magnetic field of antenna at conductive surface, therefore, industry usually adopts magnetic thin film (as the companies such as TDK produce) laminating FPC mode to form NFC magnetic sheet antenna in mobile phone, but one of NFC antenna key inserting mobile phone is, coil (antenna) externally can not be covered by conductive materials such as metals, otherwise signal cannot send out, a lot of mobile phone adopts metal back cover, solution unique is at present the patent of Japanese trader Maruwa, this technology opens T-slot in metal back cover, be double-decker with the NFC antenna magnetic sheet that FPC makes simultaneously, to be arranged on interior of mobile phone, the integral thickness of mobile phone will be made to increase, and when the NFC antenna magnetic sheet made of FPC is installed, operation is many and production cost is high.
Summary of the invention
The NFC antenna used for present mobile phone is generally the thickness problem making installation procedure many production cost height restriction assembling defensive position machine with the double-decker that FPC makes, the utility model aims to provide and a kind ofly does not need to be shaped separately can be printed directly on the NFC antenna of mobile phone front shroud inside, espespecially a kind of NFC antenna being applied to mobile phone.
In order to realize above-mentioned effect, the technical solution adopted in the utility model is: a kind of NFC antenna being applied to mobile phone, mobile phone is divided into mobile phone front shroud, mobile phone screen, cell phone mainboard and phone housing three part, mobile phone front shroud, mobile phone screen, cell phone mainboard and phone housing cooperatively interact and sequentially install, wherein cell phone mainboard is arranged on phone housing inside, mobile phone screen is arranged on before cell phone mainboard, mobile phone front shroud is arranged on before mobile phone screen, described mobile phone front shroud is divided into the transparent region corresponding with display screen and lower edges leaves the light tight region adopting silk-screen to have ink, lighttight region adopt Conductive silver ink silk-screen have NFC antenna, described NFC antenna comprises NFC antenna circuit and wire jumper, needs the region of wire jumper is printed on dielectric ink, dielectric ink is printed with wire jumper, then is printed on insulating barrier on antenna area at NFC antenna circuit.
The size of described mobile phone front shroud is greater than the size of mobile phone display screen.
The transparent region of described mobile phone front shroud is corresponding with the size of mobile phone display screen.
Described mobile phone front shroud adopts tempered glass cutting to form.
The silver content of described Conductive silver ink is 50-60%.
The silver content of described Conductive silver ink is 55%.
The beneficial effects of the utility model: the utility model adopts the method for silk-screen, by NFC antenna and wire jumper printing mobile phone front shroud inner surface, abandon employing FPC and make double-deck NFC antenna magnetic sheet, be presented as and lacked parts, not only reduce production cost, reduce assembling difficulty, lacked a part simultaneously and be arranged on interior of mobile phone, make the thickness of mobile phone can be thinner.
Accompanying drawing explanation
Fig. 1 is that the utility model is for STRUCTURE DECOMPOSITION schematic diagram during mobile phone.
Fig. 2 is the structural representation of mobile phone front shroud inner surface in the utility model.
Fig. 3 is the cross-sectional schematic of the utility model antenna printed layers.
Accompanying drawing mark illustrates: 1-front shroud, the light tight region of 11-, 12-transparent region, 2-mobile phone screen, 3-cell phone mainboard, 4-phone housing, 6-NFC antenna stack, 7-insulating barrier, 8-wire jumper layer.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, as shown in drawings, a kind of NFC antenna being applied to mobile phone, mobile phone is divided into mobile phone front shroud 1, mobile phone screen 2, cell phone mainboard 3 and phone housing 4 three part, mobile phone front shroud 1, mobile phone screen 2, cell phone mainboard 3 and phone housing 4 cooperatively interact and sequentially install, wherein cell phone mainboard 3 is arranged on phone housing 4 inside, mobile phone screen 2 is arranged on before cell phone mainboard 3, mobile phone front shroud 1 is arranged on before mobile phone screen 2, described mobile phone front shroud 1 adopts tempered glass cutting to form, be divided into the transparent region 12 corresponding with display screen and lower edges and leave the light tight region 11 adopting silk-screen to have ink, the size of mobile phone front shroud 1 is greater than the size of mobile phone display screen, transparent region 12 is corresponding with the size of mobile phone display screen, lighttight region adopt Conductive silver ink silk-screen have NFC antenna, described NFC antenna comprises NFC antenna circuit and wire jumper, needs the region of wire jumper is printed on dielectric ink, dielectric ink is printed with wire jumper, then on antenna area, is printed on insulating barrier 7 at NFC antenna circuit.
Be applied to the manufacture craft of the NFC antenna of mobile phone: described manufacture craft mainly comprises the following steps: (1) modulation printed ink: modulation is a Conductive silver ink of 50-60% containing silver content, and more excellent selection is silver content is 55%; Modulate lighttight ink, also will modulate dielectric ink, the dielectric ink of UV curing type can be selected;
(2) mobile phone front shroud 1 is prepared: adopt tempered glass as the front shroud 1 of mobile phone, glass-cutting as requested, then bevelling grinding, then clean, dried for standby; Because front shroud 1 comprises the transparent region 12 corresponding with mobile phone display screen size and outer peripheral light tight region 11; According to silk-screen principle, the surface that light tight ink printing does not participate in Presentation Function to front shroud 1 inner surface is formed light tight region 11, remaining transparent region 12 need not print, and then adopts the solidification measure of ink, makes the light tight region 11 after printing firmly durable in use; Here should be specifically noted that, surface of plate glass can not have water mark.
(3) NFC antenna part is printed: adopt Conductive silver ink silk-screen to have NFC antenna circuit at light tight region 11 inner surface of mobile phone front shroud 1; Adopt silver content to be the Conductive silver ink of 55%, according to silk-screen principle, form NFC antenna layer 6 in mobile phone front shroud 1 lighttight region printing NFC circuit.
(4) wire jumper part is printed: be printed with NFC antenna circuit in the light tight region 11 of mobile phone front shroud 1 and need the region of wire jumper first to stamp dielectric ink formation insulating barrier 7, print wire jumper with Conductive silver ink again and form wire jumper layer 8, stamp one deck on the surface of antenna area more not exclusively to cover, be reserved with the insulating barrier 7 of the external contact point of antenna, the part of contact point stamps the conductive polymer glue that one deck prevents Conductive silver ink surface oxidation again, can complete the printing of wire jumper part.
(5) complete the installation of NFC antenna: above NFC antenna circuit, stick a slice ferrite magnetic matte again, only expose the external contact point of antenna, can all complete all techniques of NFC antenna silk-screen at mobile phone front shroud 1 inner surface.
The screen printing method of layer-stepping is adopted directly to print NFC antenna and wire jumper at the inner surface of mobile phone front shroud 1, abandon traditional employing FPC and make double-deck NFC antenna magnetic sheet, not only reduce production cost, reduce assembling difficulty, lack a part simultaneously and be arranged on interior of mobile phone, make the thickness of mobile phone can be thinner.
