circuit boards

Circuit boards, also known as printed circuit boards (PCBs), are rigid or flexible structures that support and electrically connect electronic components like chips, resistors, and capacitors. They consist of a flat material—usually fiberglass—with conductive pathways made of copper etched onto its surface or layers. These pathways form the circuitry necessary for electronic devices to function, allowing signals and power to flow between components. Think of a circuit board as the backbone that organizes and links all the electronic parts in gadgets like computers, smartphones, and household appliances, ensuring they operate smoothly and reliably.
