When the board doesn’t have integrated components it is more correctly referred to as printed wiring board (PWB) or etched wiring board. Still, the concept printed wiring board has grown into disuse. A PCB inhabited with electronic components is described as a printed circuit assembly (PCA), printed circuit board assembly or even PCB assembly (PCBA). The IPC advised name for assembled boards is circuit card assembly (CCA), and for assembled backplanes it is backplane assemblies. The term PCB is utilized informally for both bare and assembled boards.

What’s printed circuit board (PCB)?


A PCB mechanically supports and electrically binds electronic components by means of conductive tracks, pads and other features etched from copper sheets laminated onto a non-conductive substrate. Essential components – capacitors, resistors or active devices – are often embedded on the printed circuit board. Advanced PCBs may have components integrated in the substrate.

The reality is, PCBs can be single sided (single copper layer), double sided (2 copper layers) or multi-layer (outside plus inside layers). Conductors on diverse layers are linked with vias. Multi-layer PCBs make room for much greater component denseness.

FR-4 glass epoxy is the principal insulation substrate. A basic building block of the PCB is an FR-4 panel with a thin layer of copper foil laminated to one or both the sides. In multi-layer boards, multiple layers of material are laminated with each other.

Printed circuit boards are utilized in basically the most basic electronic devices. Alternatives to PCBs comprise of wire wrap and point-to-point construction. PCBs need the extra design effort to lay out the circuit, but producing as well as assembly can be automatic. Manufacturing circuits with PCBs is much less costly and quicker than with alternative wiring methods simply because components are mounted and wired with one part. Moreover, operator wiring errors are done away with.
