Further, printed circuit board (PCB) can be flexible PCB (abbreviation FPC).FPC can use existing
The FPC of standard.In further embodiments, it is also possible to carry out that FPC is fabricated separately out.Similarly, iron oxygen
Body using the ferrite of existing standard, and can be fitted on substrate corresponding magnet area.Other embodiments
In, ferrite can also directly produce ferrite in the magnet area of substrate.
Further, after each NFC antenna is manufactured, also including NFC antenna is packed the step of,
To be user-friendly to.In packaging, frequency of use can be indicated in NFC antenna, application method makes
With parameters such as conditions.
Further, the NFC antenna manufacture method also detects whether qualified including step S5:To shearing
To each described NFC antenna be operated frequency detecting, step S6 is carried out if unqualified) finishing:
The NFC circuit in the corresponding NFC antenna is etched using laser, to repair the NFC antenna
Working frequency.Eligible paths are detected whether by setting S5, to ensure the quality of the NFC antenna of manufacture.
The standard frequency of NFC antenna is 13.5MHz, due to by substrate laminating on a printed circuit when,
When carrying out S3 laminating steps, ferrite is fitted in when in corresponding NFC circuit, may there is error,
So as to the working frequency for causing NFC antenna shifts, communication quality is caused to decline or scrap.And pass through
S6 pre-shaping steps, are etched to NFC circuit using laser, repaired, so as to the frequency that works NFC antenna
Rate is adjusted, so that the quality and yield of product, the scrappage of the NFC antenna that reduction is got the upper hand of is effectively ensured.
Above-mentioned S6) in pre-shaping step, specially:Because NFC circuit is generally the electricity that many turn coils are formed
Road;And measured through many experiments, the width of NFC circuit coil is directly related with the working frequency of NFC.
