5.Little knowledge
PCB is an acronym for printed circuit board. It is a board that has lines and pads that connect various points together. A PCB allows signals and power to be routed between physical devices.
There are alternating layers of different materials which are laminated together with heat and adhesive such that the result is a single object.

FR4
The base material, or substrate, is usually fiberglass. Historically, the most common designator for this fiberglass is “FR4”. This solid core gives the PCB its rigidity and thickness.
You will find many different thickness PCBs; the most common thickness for print circuit board is 1.6mm (0.063"). 

Copper
The next layer is a thin copper foil, which is laminated to the board with heat and adhesive. On common, double sided PCBs, copper is applied to both sides of the substrate. When we refer to a double sided or 2-layer board we are referring to the number of copper layers (2). This can be as few as 1 layer or as many as 16 layers or more. 

Soldermask
The layer on top of the copper foil is called the soldermask layer. It is overlaid onto the copper layer to insulate the copper traces from accidental contact with other metal, solder, or conductive bits. This layer helps the user to solder to the correct places and prevent solder jumpers. Soldermask is most commonly green in color but nearly any color is possible. 

Silkscreen
The white silkscreen layer is applied on top of the soldermask layer. The silkscreen adds letters, numbers, and symbols to the PCB that allow for easier assembly and indicators for humans to better understand the board. Silkscreen is most commonly white.
