Prototype PCB boards (printed circuit board)


A printed circuit board (PCB) is for mechanically support and electrically connect electronic components. It uses conductive tracks and other features.

PCBs can be single sided (one copper layer), double sided (two copper layers) or multi-layer.

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.
