A printed circuit board (PCB) mechanically supports and electrically connect selectronic components using conductive tracks, pads and other features etched from copper sheets laminated onto a non-conductive substrate. PCBs can besingle sided (one copper layer), double sided (two copper layers) or multi-layer(outer and inner layers). Multi-layer PCBs allow for much higher component density. Conductors on different layers are connected with plated-through holes called vias. Advanced PCBs may contain components - capacitors, resistors or active devices - embedded in the substrate.
