Fr4 PCB board layer:

One layer of copper. Normally the wire-leaded components must be mounted on only one side of the PCB, with all the leads through holes, soldered and clipped.
You can also mount the components on the track surface using Surface Mount Technology (SMT) or Surface Mount devices (SMD). Surface mount circuitry is generally smaller than conventional. Surface mount is generally more suited to automated assembly than conventional. In practice, most boards are a mix of surface mount and conventional components. This can have its disadvantages as the two technologies require different methods of insertion and soldering. Conventional circuitry is generally easier to debug and repair.

Two layers of copper, one each side of the board. The components must be mounted on only one side of the PCB but you can also mount components on both sides of the PCB. Normally only surface mount circuitry would be mounted on both sides of a PCB. The components must be mounted using both through-holes tecnology or Surface Mount Technology (SMT) or Surface Mount devices (SMD). Conventional circuitry is generally easier to debug and repair.

A PCB Laminate may be manufactured with more than two layers of copper tracks by using a sandwich construction. The cost of the laminate reflects the number of layers. The extra layers may be used to route more complicated circuitry, and/or distribute the power supply more effectively.

Fr4 PCB board layout:

The PCB layout can be draw either manually or by ECAD (Electronic - Computer Aid Design) software. The manual process is useful and quick only for very easy PCBs, for more complex PCBs I suggest the second way. Nowadays inexpensive computer software can handle all aspect of PCBs pre-processing. Also is available expensive professional computer software that can direct control the fabrication processing tools
