What is circuit boards?

Circuit boards, also known as printed circuit boards (PCBs), are rigid or flexible platforms that mechanically support and electrically connect electronic components using conductive pathways, tracks or signal traces etched from copper sheets laminated onto a non-conductive substrate. They are essential for building electronic devices, providing a structured and reliable way to assemble and interconnect components like resistors, capacitors, integrated circuits, and connectors. PCBs are used in a vast array of applications, from simple consumer electronics to complex industrial and aerospace systems.
