Abstract

In this paper, a fully printed NFC tag operating at 13.56 MHz was designed and fabricated using silver nano-paste and carbon ink. The proposed NFC tag has a printed coil with an inductance of $2.74{\mu}H$ on a PI film for application to an NFC tag IC with an internal capacitance of 50 pF. Screen printing technology used in this paper has advantages such as large area printing for mass production, low cost and eco-friendly process compared to conventional PCB manufacturing process. The proposed structure consists of a circular coil implemented as a single layer using silver nano-paste and carbon ink, a jumper pattern for chip mounting between the outer edge and the center of the coil, and an insulation pattern between the coil and the jumper pattern. In order to verify the performance of the proposed NFC tag, we performed the measurements of the printing line width, thickness, line resistance, adhesion and environmental reliability, and confirmed the suitability of the NFC tag based on the full-printed manufacturing method.

본 논문에서는 은 나노 분말과 카본 잉크를 이용하여 13.56 MHz에서 동작하는 완전 인쇄형 NFC 태그를 설계 및 제작하였다. 제안된 NFC 태그는 50 pF의 내부 커패시턴스를 갖는 NFC 태그 IC에 적용하기 위해서, $2.74{\mu}H$의 인덕턴스를 갖는 원형 코일을 PI 필름 위에 설계하였으며, 전통적인 회로 제작 방식인 PCB 제조 공정에 비해 대면적 및 대량 생산, 저비용, 친환경공정 등의 장점을 가진 인쇄 전자 기술인 스크린 프린팅 기법을 이용하여 제작하였다. 제안된 구조는 단일 층으로 구현된 원형 코일, 코일 외곽과 중심부 사이에 칩 실장을 위한 점퍼 패턴, 그리고 코일과 점퍼 패턴과의 절연을 위한 절연 패턴으로 구성되어 있으며, 은 나노 분말과 카본 잉크를 이용하여 전도성 패턴과 절연 패턴을 중첩 인쇄하여 구현하였다. 본 논문에서 제안된 NFC 태그의 성능 검증을 위해 인쇄선폭, 두께, 선저항, 밀착력 그리고 환경 신뢰성 평가 등을 수행하였으며, 완전 인쇄형 제작 방식 기반 NFC 태그의 적합성을 확인하였다.
