Double-sided pcb have one layer dielectric layer in the middle, both sides are traces layer. Multilayer PCB is a multilayer traces layer, a dielectric layer between each 2 layer, a dielectric layer may be made very thin layers . Multilayer circuit board having at least three conductive layers, wherein the outer surface 2layers, while the remaining one was synthesized in the insulating plate. Electrical connection between them is usually done by plated through holes in the circuit board on the implementation of the cross section
2-28 layer is available in our factory,
Multilayer pcb use in professional electronic equipment (computers, military equipment), especially in the case of the weight and volume overload. In high-speed circuits, the multi-substrate is also very useful, they can provide more than two layer boards for the printed circuit board designers to laying cable, and provides a large area of ground and power.
