Frank Department of Electrical and Computer Engineering Queen's University Slide 1 PCB Layout using ADS November 29, 2005 Motivation Need circuit more reliable than breadboard? Working at RF/microwave frequencies? Printed circuit board (PCB) is a good solution Slide 2 PCB Layout using ADS November 29, 2005 PCB PCB done on a substrate such as FR-2 or FR-4, though at RF/microwave frequencies special low-loss substrates are used (often obtained free from Rogers Corporation) Slide 3 PCB Layout using ADS November 29, 2005 PCB Design Procedure ● Layout software is usually used to to draw the metallic traces, which tells milling machine where to move excess metal Via holes are drilled through the board as necessary ……
