Description

The NFC antenna of a kind of smart mobile phone and individual pen thereof

Technical field

The utility model relates to the smart mobile phone field with NFC payment function, in particular a kind of NFC antenna with individual pen structure.

Background technology

Along with the development of smart mobile phone technology, the function and application demand of user to smart mobile phone also can change to some extent, such as utilize with NFC (NearFieldCommunication, wireless near field communication) the smart mobile phone brush shirt once of payment function, the button that on the clothes such as trousers, certain is specified just can demonstrate the merchandise news relevant to these clothes on this mobile phone screen, and for example directly brush ring with such mobile phone, the gadgets such as necklace just can demonstrate the merchandise news relevant to this gadget on this mobile phone screen, for another example with such mobile phone brush once the pet identity disc such as dog tag just can demonstrate master message be associated with this pet etc. on this mobile phone screen.

And these functions or application are all that NFC parts by being arranged on smart mobile phone inside have come, wherein just include NFC antenna, traditional NFC antenna adopts FCCL (FlexibleCopperCladLaminate usually, flexible copper-clad plate) raw material are made into FPCB (FlexiblePrintedCircuitboard, flexible printed-circuit board) form, traditional NFC antenna be one circle ring around coiled type circuit, the head and the tail of circuit are provided with feedback point, and head and the tail two feedback point need be arranged on the same side of coil.

Traditional way is, or the mode adopting via hole to connect, or adopts the mode of wire jumper bridge joint.For front a kind of mode, the two-sided Copper Foil adopted adds via hole to realize, need boring, hole plating and two-sided making circuit, and set out the wire with a feedback point at the bottom of double sided board, this wire is electrically connected by the hole wall of conduction and the circuit of double sided board top layer, thus realizes the same side that 2 feedback points are positioned at coil; And for rear a kind of mode, be on the line layer of single sided board, after print shield layer, stamp another line layer again, and the feedback of lower sandwich circuit point is made to be in the same side of coil across a part for circuit and the feedback point of upper layer circuit.

But, front a kind of mode adopting via hole to connect, double sided board used is higher than the cost of single sided board, and the bottom seldom do not limit needs the area of etching large, can cause waste and the environmental pollution of Copper Foil, manufacturing procedure is comparatively complicated, not only increase cost, and the operation of process is more, the pollution that NFC antenna is subject to and interference more, the electrical property of finished product can be reduced.Then adopt a mode for wire jumper bridge joint, have to pass through again printing repeatedly and baking, while loaded down with trivial details manufacturing procedure adds cost, also can have influence on the reliability of NFC antenna electrical property.In addition, traditional way limits by its processing procedure, all there is the risk of short circuit in the position that processing via hole or printing are passed a bridge, and the quality of finished product also can be caused to occur unstable situation.

Therefore, prior art still haves much room for improvement and develops.
