Little knowledge - PCB Circuit Board

A printed circuit board (PCB) mechanically supports and electrically connects electronic components using conductive tracks, pads and other features etched from copper sheets laminated onto a non-conductive substrate.

Components (e.g. capacitors, resistors or active devices) are generally soldered on the PCB. Advanced PCBs may contain components embedded in the substrate.

There are three kinds of PCB, including single sided pcb (one copper layer), double sided pcb (two copper layers)and multi-layer pcb (outer and inner layers). Conductors on different layers are connected with vias. Multilayer PCBs allow for much higher component density.
