Flexible PCB (Flexible Printed Circuit Board) referred to as " soft board ", is commonly called as FPC in industry, is The printed circuit board (PCB) being made of flexible insulating substrate (mainly polyimides or polyester film), with many hardness printing electricity The advantage that road plate does not possess.For example it can be with free bend, winding, folding.The body of electronic product can be substantially reduced using FPC Product, the need for applicable electronic product develops to high density, miniaturization, highly reliable direction.Therefore, FPC is in space flight, military affairs, movement It is widely used on the fields such as communication, laptop computer, computer peripheral equipment, PDA, digital camera or product.FPC also has Good thermal diffusivity and solderability and it is easy to load, the advantages of integrated cost is relatively low.

Because the consumer products such as mobile phone, POS, Intelligent worn device have very high appearance requirement, therefore antenna is general Built in needing, NFC antenna generally now is made by the way of ferrite magnetic film and FPC unifications, wherein due to FPC circuits Design has influence on thickness, technique and the cost of product.With the development of hand-hold electronic equipments, product tends to high performance-price ratio and slim Change, then the slimming of product and high performance-price ratio turn into the task of top priority.

Utility model content

For defect of the prior art, the purpose of this utility model is to provide a kind of NFC-FPC antennas.

A kind of NFC-FPC antennas provided according to the utility model, including FPC circuits single sided board and FPC wire jumper single sided boards, Wherein：Planning has circuit on the FPC circuits single sided board；The FPC wire jumpers single sided board is provided with bridge circuit；FPC wire jumper lists Two pieces of metallic regions are provided with panel and FPC circuit single sided boards, FPC wire jumpers single sided board and FPC circuit single sided boards are welded on Together.

Preferably, the method for FPC wire jumpers single sided board and FPC circuit one side plate welds is ultrasonic welding method or material strip SMT method.

Preferably, welding FPC wire jumpers single sided board and during FPC circuit single sided boards, FPC wire jumper single sided boards have circuit one side and The one side that FPC circuit single sided boards have bridge circuit is fitted.

Preferably, when welding FPC wire jumpers single sided board and FPC circuit single sided boards, circuit and FPC on FPC wire jumper single sided boards Bridge connection on circuit single sided board forms complete circuit.

Compared with prior art, the utility model has following beneficial effect：

1st, by two single sided board base materials, the production with dual platen base material same thickness and performance is produced by auxiliary process Product；

2nd, integrated cost of the present utility model is less than the cost of equal dual platen base material.

Fig. 1 is NFC-FPC structure finished product outline drawing；

Fig. 2 is NFC-FPC exploded perspective view.

In figure：1-FPC wire jumper single sided boards；2-FPC circuit single sided boards；3- metallic regions.

Embodiment

The utility model is described in detail with reference to specific embodiment.Following examples will be helpful to this area Technical staff further understands the utility model, but does not limit the utility model in any form.It should be pointed out that to ability For the those of ordinary skill in domain, without departing from the concept of the premise utility, some changes and improvements can also be made. These belong to protection domain of the present utility model.

As depicted in figs. 1 and 2, a kind of NFC-FPC antennas provided according to the utility model, including FPC circuit single sided boards With FPC wire jumper single sided boards, wherein：Planning has circuit on the FPC circuits single sided board；The FPC wire jumpers single sided board be provided with across Bridge circuit；Two pieces of metallic regions, FPC wire jumpers single sided board and FPC are provided with FPC wire jumpers single sided board and FPC circuit single sided boards Circuit single sided board welds together.

Further, the method for FPC wire jumpers single sided board and FPC circuit one side plate welds is ultrasonic welding method or material Band SMT method.

Further, when welding FPC wire jumpers single sided board and FPC circuit single sided boards, FPC wire jumper single sided boards have the one side of circuit The one side for having bridge circuit with FPC circuit single sided boards is fitted.

Further, welding FPC wire jumpers single sided board and during FPC circuit single sided boards, circuit on FPC wire jumper single sided boards and Bridge connection on FPC circuit single sided boards forms complete circuit.

Dual platen base material typesetting rate is 70%-80%, and identical single sided board base material typesetting rate is 70%-80%, PFC wire jumpers The typesetting rate of single sided board is more than 95%, and identical single sided board base material is the 55% of dual platen base material cost, in summary, this practicality It is new saved while having reached with dual platen same performance 30% cost.

In first time case study on implementation, artificial one layer of the laminating between one side FPC circuits single sided board and FPC wire jumper single sided boards The gold-plated soft boards of FPC.Test result indicates that can be in the environment of vibrating and falling vibration, it is ensured that ultrathin NFC-FPC circuits are not It is pierced, it is ensured that performance；But due to adding material, increase laminating cost, so cost is less desirable on the whole.

In second of case study on implementation, the mode Contact antenna of conventional shell fragment is substituted using golden steamed bun, cancels original shell fragment. The golden steamed bun is a Flexible Connector, using the characteristic of silicon rubber of golden steamed bun itself, realizes electrical contact.Test result indicates that Can be in the environment of vibrating and falling vibration, it is ensured that circuit is not pierced, it is ensured that performance；Your contact flat spring also reduced simultaneously Material Cost, and the demands such as the cost, performance, reliability of terminal can be met.
