What is a PCB? A Printed Circuit Board, or PCB, is a custom-designed board used to electrically connect electronic components using conductive tracks, pads, and other features etched from copper sheets laminated onto a non-conductive substrate. PCBs are the foundation of most electronic devices we use today, from smartphones and computers to medical equipment and…

Understanding High-Speed Signals What Makes a Signal High-Speed? A signal is considered high-speed when its frequency is high enough to cause significant signal integrity issues, such as reflections, crosstalk, and electromagnetic interference (EMI). The exact frequency at which a signal becomes “high-speed” depends on various factors, including the PCB material, trace length, and rise time…
