Product Details


   Multi-layer PCB has many advantages, such as: high assembly density, small size; short connection between electronic components, signal transmission speed, convenient wiring; good shielding effect, and so on. The number of layers of the multilayer board is not limited. Currently, there are more than 100 layers of PCBs, and four-layer and six-layer boards are common.

PCB stack structure

1.  Four-layer structure:

       TOP-------------Singnal top layer signal layer

        Inner1----------GND Inner electrical layer

        Inner2----------POWER Inner Electrical Layer

        BOTTOM----------Singnal2 bottom signal layer

2. Six-layer laminate structure:

        TOP------------------------Single1 Signal Layer 1

        Inner1---------------------GND Inner Electric Ground

        Inner2---------------------Single2 Signal Layer 2

        Inner3---------------------Power Internal Power Supply

        Inner4---------------------GND Inner Electrical Land

        Bottom---------------------Single3 Signal Layer 3
