Single Sided or Single Layer Types of PCB
•Single Sided PCB is the simplest low cost PCB or printed circuit board. These types of PCB has only one single layer of the base  substrate (Fiberglass) and one single conductive (copper) layer. Holes for electronic components are generally not plated through. Layout for the electronic components is on one side and the conductive circuit is on the other side. Since, there is only conductive layer forming the circuit, it is called single sided PCB or One Layer PCB or Single Layer PCB.

Light Emitting Diode The “Light Emitting Diode” or LED as it is more commonly called, is basically just a specialised type of diode as they have very similar electrical characteristics to a PN junction diode. This means that an LED will pass current in its forward direction but block the flow of current in the reverse direction. • Light emitting diodes are made from a very thin layer of fairly heavily doped semiconductor material and depending on the semiconductor material used and the amount of doping, when forward biased an LED will emit a coloured light at a particular spectral wavelength. • When the diode is forward biased, electrons from the semiconductors conduction band recombine with holes from the valence band releasing sufficient energy to produce photons which emit a monochromatic (single colour) of light. Because of this thin layer a reasonable number of these photons can leave the junction and radiate away producing a coloured light output. • Also, nearly al...
