According to the number of layers, the custom printed circuit boards are divided into three major categories, namely, single layer, double layer and multilayer circuit board.

The first is the single layer pcb. On the most basic PCB, the parts concentrate on one side and the wires focus on the other.

Double layer pcbs are extensions of a single layer, and double sided layers are used when single-layer cabling does not meet the needs of electronic products.

A multilayer board is a printed circuit board in which three layers of conductive graphic layers and insulation between them are laminated and interconnected in accordance with the requirements.
