Abstract

In this study, we developed a micropattern technology in the shape of RFID TAG antenna using ultrasonic micropattern manufacturing system developed to enable micropattern technology. The ultrasonic tool horn in longitudinal vibration mode was installed in the micropattern manufacturing system to develop the ultrasonic press technology for the micropattern antenna shape of the RFID TAG antenna shape on the insulating sheet surface. The ultrasonic shaping technology was manufactured by applying the resonance design technique to a 60kHz tool horn, and by using the micropattern manufacturing system, the coil wire having a thickness of 25㎛ can be ultrasonically press-molded on an insulating sheet of 200㎛ or less. In ultrasonic press technology, the antenna shape having a minimum line width of 150㎛ could be molded without disconnection, peeling, or twisting of the coil wire.

본 연구에서는 미세패턴 성형이 가능하도록 개발된 초음파 미세패턴 제조시스템을 이용하여 RFID TAG 안테나 형상의 미세패턴 성형기술을 개발하였다. 미세패턴 제조시스템에 종진동 모드의 초음파 공구 혼을 설치하여 절연시트 표면에 RFID TAG 안테나 형상의 미세패턴 안테나 형상을 초음파 압입 성형공정 기술을 개발하였다. 초음파 성형기술은 60kHz 공구 혼을 공진설계 기법을 적용하여 제작하였고, 미세패턴 제조시스템을 이용하여 200㎛ 이하의 절연 시트지에 두께가 25㎛의 코일 와이어를 초음파 압입 성형을 할 수 있다. 초음파 압입 성형 시 코일 와이어의 단선, 박리 및 꼬임 현상 없이 최소선폭 150㎛인 안테나 형상을 성형할 수 있었다.
