Since the work of engineer Paul Eisler working in the United Kingdom using PCB as a component to make the radio for the first time, PCB has been considered a most important component in electronic assembly. However, after being commercialized, the PCB was officially crowned “Mother of electronic components”. And so far the PCB has not yet had an alternative ability, so it deserves more than the name of the “Electronic Components King” component.

4 layer PCB means there are 4 layers to rout electrical signals: Top Layer, Inner Layer 1, Inner Layer 2 and Bottom Layer. TOP and bottom layers are the outer layers where we are placing components and routing. Inner layer 1 and inner layer 2 are in the core, and normally used as power planes or used for signal routing. Therefore, 4 layer PCB = 3 Signal layer + GND layer or 4 layer PCB = 2 signal layers + a VCC layer + a GND layer.
