According to PCB printed circuit board number of layers classification: PCB ( power bank pcb board Printed ) printed circuit boards are divided into single panel, double sided plate and multilayer board. The common multilayer board is usually 4 ply or 6 ply, and the complex multilayer board can reach dozens of layers.


The PCB board has the following three main types of division:

Folding single panel

Single-SidedBoards on the most basic PCB ( HDI pcb Printed circuit board), the parts concentrate on one side and the wires focus on the other. Because the wires only appear on one side, the PCB is called a single panel (Single-sided).

Folding double sided plate

Double-SidedBoards both sides of the circuit board have wiring, but to use the two sides of the wire, there must be between the two sides have proper circuit connection. The bridge between such circuits is called the via. The guide hole is a small hole filled or coated with metal on the PCB. It can be connected with the wires on both sides.


Folding multilayer board

Multi-LayerBoards ( china pcb manufacturer ) in order to increase the area of wiring, multilayer boards use more single or double sided wiring boards. With a double and two single block as inner layer as the outer layer or two double-sided printed circuit board for the outer layer of the inner layer, two single block, through the positioning system and an insulating adhesive material alternately printed circuit board according to the design requirements for interconnection together and the conductive pattern becomes the four layer, six layer printed circuit board, also known as for multilayer printed circuit board.
