On electronic contact 12, you can realize chip 10 function.As shown in figure 3, aforementioned electronic contact 12 is distributed in 11 bottom surface of ontology
The left and right sides, along the spacing between 2 adjacent electronic contacts 12 of 11 length direction of ontology (may be defined as first direction A)
For W1.
It please refers to Fig.2 and Fig. 3, inductor 20 has that a magnetic core 21, that a coil 22 is wound in magnetic core 21, an adhesive body 23 is close
Seal the top surface that adhesive body 23 is arranged with coil 22 and two electrodes 24 for aforementioned magnetic core 21.Former electrodes 24 can use conduction
Material is simultaneously made with the methods of printing, coating or plating, and is electrically connected in the conducting wire of coil 22.As shown in figure 3, two electricity
Pole 24 is W2 along the spacing between parallel first direction A, and spacing W2 is less than or equal to spacing W1 so that 12 edge of electronic contact
It chip 10 and connect the projection in direction with inductor 20 and entirely fall in described two electrodes 24.
The radio frequency identification module of the present embodiment can print when manufacture or applying conductive material is in the pre- of electrode 24
Positioning is set, and the equipment such as chip mounter (Surface Mount System) is then used to put the electronic contact 12 of chip 10 automatically
In the electrode 24 of inductor 20, reflow (Reflow) is then carried out to form electrode 24, is completed at the same time chip 10 and inductor 20
Electric connection, production process is simple and quickly.
It is noted that the inductor that the utility model is applicable in is not limited with previous embodiment.Magnetic core and sealing
Body may also be integrated into single magnetic core element using magnetic composite, equally by coil encapsulation in single magnetic core element
Portion.
By preceding description it is found that radio frequency identification module provided by the utility model can automate quick manufacture,
And need not in addition be set using printed circuit board (PCB) be used as substrate, be conducive to microminiaturization, and further decrease material at
This.
