Embodiment Construction

[0009] The present invention will be described in detail below in conjunction with specific embodiments.

[0010] Such as figure 1 , the contactless card involved in the present invention comprises radio frequency module 1, module welding pad 4, polyester film 5, PVC card base 6, also comprises the coil 3 and film capacitor 2 that are made by corrosion method, coil and film capacitor and radio frequency The modules are electrically connected to the mylar.

[0011] The method involved in the present invention makes contactless card,

[0012] The first step in the process is module encapsulation.

[0013] First, thin the disk chip to 0.15-0.18mm, and then cut it; use a machine to combine the cut chip with silver paste and strips, and reach the tangential thrust standard> 500g / mm 2 ; For the finished semi-finished product to be soldered with gold wire, use gold wire to connect the solder joints and strips of the chip to form a path, and test to meet the following standards: th...

Abstract

This invention discloses a method for manufacturing untouching card used in smart card field and the untouching card manufactured by the method. The manufacturing method includes following steps: A. packing the module; B. making corrosion coil; C. processing the corrosion coil and the module in combination; D. laminating to make card. The untouching card manufactured by this method includes radio-frequency module, module soldering disk, polyester film, PVC card base, as well as coil and film capacitor made by corrosion, coil and film capacitor being electrically connected with the radio-frequency module on the polyester film. The advantageous effect of the invention is that the manufacturing process is simpler, the properties of the products are more stable and reliable and the consistance of the products is higher than prior art because the method of corrosion is used.

Description

technical field [0001] The invention belongs to the field of smart cards, in particular to a method for making a non-contact card. Background technique [0002] Now, contactless cards, such as transportation cards, consumer entertainment cards, etc., have become an indispensable consumer tool in people's lives due to their irreplaceable simple and practical advantages. The conventional method adopted at the time was winding coils with enameled wires. This production method is greatly limited by equipment factors, and the production capacity of the equipment is very low. The production cannot achieve mass production. If a large amount of equipment is invested, it will increase the cost. Furthermore, the coil made by the winding method is affected by human factors, and a slight deformation of the coil will affect the deviation of the working frequency of the card, thereby causing the card to work unstable. Contents of the invention [0003] One of the technical problems to ...
