According to the characteristics of the circuit board, the circuit board is divided into FPC, PCB, and FPCB. Circuit board includes many kinds of working layers, such as signal layer, protective layer, silk screen layer, internal layer, etc.
Before designing multilayer PCB circuit board, the designer needs to determine the circuit board structure according to the circuit size, the size of the circuit board, and the EMC, it decides to adopt four or six layers. After determining the number of layers, the location of the inner layer and the distribution of different signals on these layers are determined. This is the choice of multilayer PCB stack structure.
Many factors need to be considered to determine the stacked structure of multilayer PCB boards. In terms of routing, more layers are better for routing; the cost and difficulty will increase. For the manufacturer, whether the stack structure is symmetrical or not is the focus of attention. Therefore, the selection of layers needs to consider all aspects of the needs in order to achieve the best balance.( custom pcb board)
