Analysis of the Signal Transmission Characteristics with Curvature of PCB Pads

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.
