PCB-Printed Circuit Board

A printed circuit board (PCB) serves the purpose of interconnecting electronic components within a circuit. It is composed of conductive layers, typically crafted from copper, which are laminated onto or sandwiched between non-conductive layers. Electronic components are affixed to these conductive layers through soldering, establishing both electrical connections and mechanical stability.

PCBs are available in several varieties:

Single-sided: Contains a single layer of copper.

Double-sided: Features two layers of copper, one on each side of the substrate.

Multi-layer: Comprises multiple copper layers interspersed with insulating layers, facilitating a greater density of components.

PCBs are extensively utilized in electronic devices due to their capacity to streamline manufacturing and assembly processes, resulting in more cost-effective and rapid mass production. There are design tools that aid in the creation of layouts. Multi-layer PCBs are especially prevalent in surface mount technology, although they present challenges in terms of repair and modification. Alternatives such as wire wrap and point-to-point construction have become infrequently used.
