Today we are going to tell you what’s the meaning and what’s the importance of the “layer” in PCB manufacture.
The layers of a PCB refer to the copper layers. A PCB is made by laminating copper layers with the substrate. Except for single-sided boards which have one layer of copper, boards with two or more sides have an even number of layers. Components are soldered on the outermost layers, and the other layers serve to connect the wires. However, some high-end PCBs now also embed components inside the inner layers of the PCB.
The number of layers and the size of a specific board determine the power and capacity of the PCB. As the number of layers increases, so does the functionality.
In the next article, we will explore the factors that determine how many layers a PCB is designed to have.
