Double Sided PCB

Double-sided Board only has one dielectric(for example, glass fiber) between two copper foil, all traces are located on two copper layer. Multi-layer board is multi double-sided board, every two layer has dielectric, and the dielectric is thinner. Multi-layer board has at least three conducting layers, two of them are on the outer surface, and the remaining layer is integrated into the insulating board.The electrical connection between them is achieved through plated through holes on the cross section of the circuit board.

Multi-layer board is better than single-sided and double-sided board on function, but the more layers, the higher the production cost. The longer the processing time, and the more complicated the quality inspection. However, under the cost comparison of the same area, although the cost of Multi-layer circuit boards is higher than that of Single-layer and Double-layer board, the cost difference between the two is not obvious when considering a variety of factors. With the advancement of technology, printed circuit boards have more than 100 layers, which are mainly used for precision aerospace instruments and medical equipment.
