About Multilayer PCB

The biggest difference between multilayer PCB and single panel and double panel is that the internal power supply layer (to maintain the internal power layer) and the ground layer are added. The power supply and ground wire network are mainly wired on the power supply layer. However, the multilayer wiring is mainly the top and bottom layer, with the middle wiring layer as a supplement. Therefore, the design method of multilayer.
PCB is basically the same as that of double-panel. The key lies in how to optimize the wiring of the internal electrical layer, so that the wiring of the PCB is more reasonable and the electromagnetic compatibility is better. A variety of processes, to provide customers with cost-effective PCB.
