Printed circuit board layout

PCB (Printed circuit board)

Printed circuit board is primarily an insulating material used as base, into which conductive strips are printed. The base material is generally fibreglass, and the conductive connections are generally copper and are made through an etching process.  The main PCB board is called the motherboard; the smaller attachment PCB boards are called daughter boards or daughter cards.

PCB board design defines the electrical pathways between components. It is derived from a schematic representation of the circuit. When it is derived, or imported from a schematic design, it translates the schematic symbols and libraries into physical components and connections

PCB layout

The PCB layout is a mirrored positive one- black on white. The PCB layout is printed 1:1 on paper by using a laser printer or copier machine. The laser printer or copier toner will not run out when it gets wet or oily. Therefore by using a laser printer the output will be fine and form in high quality of printing. It might be possible that the toner texture on the layout prints from the laser printer is not dense enough and passes too much light. However, results might be improved by setting the toner density.
