Understanding PCB Visualizer

What is a PCB?

A printed circuit board (PCB) is a fundamental component in modern electronics. It is a flat board made of insulating materials, such as fiberglass or plastic, with conductive tracks, pads, and other features etched onto its surface. PCBs provide a means to mechanically support and electrically connect electronic components using conductive pathways, tracks, or signal traces.
