Multilayer PCB China Advantages

Multilayer PCB board have high assembly density and smaller size.
During multilayer PCB manufacturing, Multilayer circuit board laying is convenient and the laying length is shortened
The wiring between the electronic components of the multi-layer PCB circuit board is reduced, and the data signal transmission rate is improved during PCB manufacturing service, such as multilayer PCB prototyping and multilayer PCB fabrication.
For electronic products with higher heat dissipation requirements, a metal core heat dissipation layer can be set on the multilayer circuit board to facilitate the requirements for special functions such as shielding and heat dissipation

Double -Sided & Multi Layered PCB

Double sided printed circuit 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 circuit 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 printed circuit boards 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 PCB, the cost difference between the two is not obvious when considering a variety of factors. With the advancement of technology, PCB printed circuit board have more than 100 layers in PCB industry, which are mainly used for precision aerospace instruments and medical equipment.
