The first is a single -to -be, on the most basic PCB, parts are concentrated on one side, and the wires are concentrated on the other side. Because the wire only appears on one side, it is called this PCB called a single -sided line board. Single panels are usually simple and low in cost, but the disadvantage is that it cannot be applied to too complicated products.

The double -panel is an extension of a single -to -surface panel. When the single -layer wiring cannot meet the needs of electronic products, the double panel must be used. Both sides have copper covering and wiring, and can be used to drive the line between the two layers through the holes to form the required network connection.

Simply understand the classification of the circuit board

Multi -layer board refers to a printed board that has an insulating material with a conductive graphic layer of more than three layers and the insulation material between them, and the conductive graphics intermittently interconnect. Multi -layer line board is the product of the development of electronic information technology towards high speed, multifunctional, large capacity, large -volume, small volume, thin, and lightweight direction.
