PCB (Printed Circuit Board) is a thin board where the electronic components, which are in pairs and assemblies, where the sides are made of copper lining to solder the legs of the components. PCB can be more than 1 layer, which I know maximum up to 12 layer.PCB is made of fiber material or the like on the non conductive part. The thickness of copper on PCB is various, there are 35 micrometer there is also a 17-18 micrometer.
Other PCB materials are phenolic or pertinax paper, usually brown, this type of material is more popular because of its cheaper price.For PCB in use for Through hole plating, usually wearing a fiberglass, because the fungus does not like this material, and The material is stronger and not easy to bend in comparison with pertinax.PCB can be found in almost all electronic equipment, such as radio, mobile, television, and others.
There are several different types of PCBs according to their usefulness: 1 side PCB (commonly used in electronic circuit such as radio, TV, etc.) PCB double side (ie both sides of PCB used to connect components) and PCB multi side (PCB part outside or inside used as media Conductor, for example in PC circuits).
