Embodiment Construction

[0016] Refer to attached figure 1 The design is as follows: the coil height can be adjusted by using the adjustable smart card coil method. It is used in the contactless smart card coil design, which includes adjustable coils, wiring needle boards, antenna contact copper foil, and modular tools; the architecture is: adjustable coils based on wiring The needle board (eg: the thickness is only 2MM thick (0.5mm bottom plate, 1.5mm needle length) is equivalent to the thickness of 2 standard sample cards) for arbitrary wiring design, and the copper foil of the antenna contact is used as the connection medium between the adjustable coil and the modular machine tool , the module tool is used as the carrier of the test module.

[0017] Place the module of the coil to be designed on the module machine tool, select the adjustment coil and the corresponding wiring needle board required for the design, and conduct the resonance and Q value test of the coil based on the wiring needle board...

Abstract

The invention discloses an implementation device for designing a non-contact intelligent card coil by adopting an adjustable coil, and belongs to a device for testing and designing a non-contact intelligent card. The device for assisting the standardized design of the non-contact intelligent card comprises four parts, namely the adjustable coil, a wiring needle plate, antenna contact copper foils and a module machine tool. The two antenna contact copper foils are integrated with the module machine tool and externally connected with the adjustable coil, and the coil is designed in a winding mode based on a wiring needle plate. Not only can random switching be realized and connectivity be ensured when a non-contact module is tested, but also the adjustable coil can satisfy any specification of Class 1, Class 2, Class 3, Class 4, Class 5 and Class 6 specified by a non-contact standard protocol and design of a special-shaped coil, and operation is simple and quick.

Description

technical field [0001] The invention relates to the field of non-contact smart card coil design and testing, and provides a quick coil design method and performance verification. Background technique [0002] With the popularization and wide application of contactless smart cards, the need for diversified designs of contactless smart cards is more urgent. In the design stage, the coil design, as a key step, will have a great impact on the overall performance and reliability of the smart card, and the height-adjustable design of the coil becomes particularly important; [0003] At present, the design of coils is all designed with disposable paper coils. The paper coil itself has solidified a coil type. The subsequent design can only be based on the existing coil type for simple resonance and Q value adjustment, and the disposable coil needs It is connected to the module by welding, and every time the coil is replaced, the module needs to be re-welded to connect. This operati...
