PCB Impedance Is Not a Minor Issue. If It Is Ignored During Design, Problems Can Easily Occur Later.
When many people design a PCB, they first focus on trace width, trace spacing, hole size, board layers, and component placement. They may think that as long as the DRC passes, the board should be fine. However, if the board involves USB, Ethernet, DDR, LVDS, HDMI, RF signals, or high-speed communication interfaces, impedance can no […]
