Abstract

When the integration density and operating frequency increase in the electronic circuits, it is important to improve the signal transmission characteristics. In this paper, the signal transmission characteristics of the printed circuit boards are analyzed with the curvature of the pads. From the simulation results, signal transmission characteristics are improved when pad curvature increases. Pad curvature more effects on signal transmission characteristics when the thickness of the transmission line and the length of the transmission decrease.

전자 회로의 집적도와 동작 주파수가 증가함에 따라 신호 전달 특성을 향상시키는 것이 중요하다. 본 논문에서는 인쇄 회로 기판에서 패드의 곡률 변화에 따른 신호 전달 특성을 분석하였다. 시뮬레이션 결과, 곡률이 커질수록 신호 전달 특성은 개선되었고, 전송선로의 두께가 얇을수록 곡률 변화에 더 적은 영향을 받으며, 길이가 짧을수록 곡률 변화에 더 큰 영향을 받는 것을 확인할 수 있었다.
