Product Details

PCB multilayer board refers to a multilayer circuit board used in electrical products, and multilayer boards use more single-sided or double-sided wiring boards. 

Multi-layer PCB function

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