Advantages of multilayer circuit boards
1, the multi-layer circuit board assembly density is high, the size is small, with the volume of electronic products is getting smaller and smaller, the function of PCB circuit board is also put forward higher requirements, the demand for multi-layer circuit board is also increasing.
2, the selection of multi-layer PCB circuit board laying line is convenient, the length of the laying line is greatly shortened, the laying line between the electronic components is reduced, but also improve the data signal transmission rate.
3. For the high-frequency circuit, after entering the ground, the signal line has a stable and low characteristic impedance to the ground, and the characteristic impedance of the power circuit is greatly reduced, which has a significant intercepting effect.
