The present invention relates to an NFC (Near Field Communication) and more particularly to an NFC ring and a processing flow thereof.
NFC stands for a near field wireless communication technology and is a kind of non-touchable identification and interconnection technology. By NFC, the near field wireless communication can be performed among a mobile device, a consumable electronic product, a PC (Personal Computer) and a smart control tool. NFC provides a simple and touchable solution, allowing a consumer to exchange information, access contents and services easily and intuitively. As a new communication technology, NFC stands out in many aspects, such as fast data transmission speed, high security, low cost and expended energy. Due to these functions, NFC is given more fantasies; for example, an NFC ring can catch people's attention. However, as the size of a ring is limited, the signal transmission and reception effect is not very perfect.
For an NFC ring sold on the markets, the NFC antenna is normally disposed on a curved surface of the ring as a surrounding coil, and then the outer layer of the ring is packaged. Nevertheless, as the induction area in this method is smaller, the access range is limited and the data can be stolen. Therefore, this kind of product is unable to spread out widely.
Referring to
Step 1
A surrounding antenna coil 20 is sheathed into a ring body 10.
Step 2
The antenna coil 20 is moved into a designated holding groove 12, and a head and a tail of the antenna coil 20 are put on a top of the ring body 10.
Step 3
The antenna coil 20 on the top is forced into a top groove 13 of the ring body 10 by a jig.
Step 4
A PCB (Printer Circuit Board) 30 is put in and tightened, and then the head and the tail of the antenna coil 20 are welded on the PCB 30.
Step 5
The antenna coil 20 is forced into a containing groove 14 at both sides of the ring body 10, and tightly enclosed in the groove of the ring body 10, followed by performing a first functional test.
Step 6
After passing the first functional test, potting adhesive A is filled into the top groove 13 to seal the PCB 30.
Step 7
A piece of decorated leather 40 is emplaced.
Step 8
The decorated leather 40 is attached in the groove of the ring body.
Step 9
The ring body is packaged by resin glue 50 which is solidified under a normal temperature, and the resin glue 50 can be polished as request, followed by passing a functional test to accomplish the product.
Accordingly, there are still some shortcomings for the abovementioned conventional NFC ring; therefore, this conventional NFC ring is indeed not a good design and needs to be improved.
Accordingly, an objective of the apparatus disclosed herein is to provide an NFC ring having a flat-bar FPC and a processing flow thereof.
To achieve the aforementioned object, disclosed herein is an NFC ring body, a flat-bar FPC and crystal glue. By the provision of the flat-bar FPC, the magnetic induction area of the NFC ring can be maximized, and for a same induction area, the access range and the anti-interference efficiency are all better than those of the conventional NFC ring produced by using a surrounding antenna coil. In addition, for the NFC ring produced by using the flat-bar FPC, the processing flow can be simplified to improve the production efficiency and the yield of the product, and the NFC ring can be made more miniaturized.
Furthermore, due to the unique induction method of the NFC ring, the data in the ring can be prevented from being stolen, thereby protecting the consumer's rights.
To enable a further understanding of the said objectives and the technological methods of embodiments of the invention herein, the brief description of the drawings below is followed by the detailed description of the preferred embodiments.
The present disclosure relates to an NFC (Near Field Communication) ring having a flat-bar FPC (flexible printed circuit) and a processing flow thereof, and more particularly to an NFC ring and a processing flow thereof, wherein by providing a flat-bar FPC, the signal transmission and reception effect as well as the anti-interference efficiency can be improved, along with that the processing flow can be simplified to improve the production efficiency and the yield of the product. In addition, the NFC ring can be made more miniaturized, and the data in the NFC ring can be prevented from being stolen by the unique induction method thereof.

An interior of the flat-bar FPC A2 that has been already equipped with the anti-interference function is provided with plural antenna beams A21 in an equal length, an IC (Integrated Circuit) A22, a capacitor A23 and plural pads A24, A25. By enclosing the flat-bar FPC A2 on the groove surface of the ring body A1 and welding the plural pads A24, A25, the NFC magnetic induction area can be maximized, thereby improving the signal transmission and reception effect as well as the efficiency in preventing from the interference among the metallic ingredients and the electronic parts on the ring body. In addition, the processing flow of the NFC ring A0 can be simplified to improve the production efficiency and the yield of the product effectively. Furthermore, the NFC ring A0 can be made more miniaturized.
The crystal glue A3 which is solidified under a normal temperature is used to seal the abovementioned components, achieving the purposes of water-proofing and beautification to the product.
