Embodiment Construction

[0016] The present invention will be further described below in conjunction with specific examples.

[0017] The invention discloses a method for manufacturing a non-contact smart card with metallic pigments on its surface.

[0018] The first step is to position the punching holes, and punch out several through holes that meet the specifications of the non-contact smart card chip on a polycarbonate material layer.

[0019] The second step is winding. On the ultrasonic equipment, several antenna groups composed of copper wires are fixed on the polycarbonate material layer, and the two ends of the antenna copper wires are placed in the through holes.

[0020] The third step is to package the chip, paste the non-contact smart card chip on the through hole, and its solder joint corresponds to the position of the antenna wire head, and the non-contact smart card chip is bonded by butt welding. The smart card chip is welded and fixed to the antenna wire head.

Abstract

The present invention discloses a contactless smart card having a surface with metal pigment, and relates to the physics field and the smart card manufacturing technology. The objective of the present invention is to mainly solve the problems that the stripping degree of a card body is unqualified and the color difference of an antenna coil is prominent after the metal pigment is used. The manufacture method of the contactless smart card provided by the invention comprises the production processes of location punching of an antenna circuit layer, patching, chip encapsulation, pre-lamination, lamination and die cutting. The manufacture method of the contactless smart card is applicable to mass production of the contactless smart card having a surface with metal pigment.

Description

technical field [0001] The invention relates to the field of physics and smart card manufacturing technology, in particular to a method for manufacturing a non-contact smart card with metal pigments on the surface. Background technique [0002] Usually, the non-contact smart cards we use are mainly used in transportation, access control, etc. This type of card will not use gold, silver, and pearlescent pigments to print the entire surface of the smart card, because the use of such pigments will cause the card to be damaged. The inner coil and chip produce serious color difference on the surface of the card body, affecting the appearance. [0003] However, with the advent of the replacement of financial chip smart cards, there is a direct demand for smart cards with obvious customer logos such as gold and silver on bank cards. After experiments, smart cards using such metal pigments, due to the characteristics of the material , The peeling degree of the card body is basicall...
