In general, a smart card is an integrated circuit chip (hereinafter referred to as an 'IC chip') equipped with a microprocessor, a card operating system, a security module, and a memory to process a specific task inside a card made of a synthetic resin material. It is built-in and is used as a means of payment, identification, identity verification, etc. in various fields such as finance, administration, and transportation.

The smart card forms a conductive pattern (conductive wire) pattern which is multi-arranged at predetermined intervals on the inner wall surface of the card itself or the surface of a substrate (hereinafter, referred to as a substrate) embedded in the card, and the IC chip is connected to the conductive pattern. It is made by sealing the inside after connecting and mounting.

In the manufacturing process of such a smart card, there has been a wire connecting device using ultrasonic waves as a device for forming a wire pattern on the surface of a substrate. It has a vibrating punch that vibrates up and down by a conductor guide and an ultrasonic generator for drawing the supplied conductive wire to the surface of the substrate, and the predetermined manner is to press the conductive wire supplied through the conductive guide into the substrate while the vibration punch vibrates. It consisted of the structure which forms a pattern.

Accordingly, there is an advantage that can further improve product quality and productivity.

In addition, since the periphery of the groove 11 of the portion where the conductive wire 20 is inserted is softened by the hot air supplied by the warm air injector 140, the groove 11 is in close contact with the outer circumferential surface of the inserted conductive wire 20. The inner shape of the wire is deformed, and further, since both ends of the inlet side of the groove 11 are partially covered by the pressurized wire 200, the wiring state of the inserted wire 20 becomes more robust. .
