Circuit boards are classified into three major categories, single-sided boards, double-sided boards, and multilayer circuit boards, depending on the number of layers. First, a single panel, on the most basic PCB, the parts are concentrated on one side and the wires are concentrated on the other side. Such PCBs are called single-sided circuit boards because the conductors are present on only one side thereof. The single panel is generally simple to manufacture and low in cost, but has the disadvantage that the single panel cannot be applied to a complex product.

The double-sided board is an extension of a single-sided board, and is used when a single-layer wiring cannot meet the requirements of an electronic product. Copper is coated on both sides of the circuit board, so that wires are arranged between the two layers, and the wires can be connected through the through holes to form required network connection.

The multilayer board refers to a printed board having three or more conductive pattern layers laminated with an insulating material therebetween at intervals, and the conductive patterns therebetween are interconnected as required. The multilayer circuit board is a product of the development of electronic information technology in the directions of high speed, multiple functions, large capacity, small volume, thinness and light weight. The circuit board is classified into a Flexible Printed Circuit (FPC), a rigid Printed Circuit (PCB) and a Flexible Printed Circuit (FPCB) according to its characteristics.
