If you interested in 4-layer Rogers Tin-sprayed PCB Board, please contact with us. We follow the quality of rest assured that the price of conscience, dedicated service. 4-layer PCB means that the printed circuit board is made of 4 layers of fiberglass. There are four wiring layers: top layer, bottom layer, VCC and GND. Through holes, buried vias and blind vias are generally used for interlayer connection. There are more buried vias and blind vias than double-sided. In addition, try not to run signal lines on the VCC and GND layers.
4-layer PCB boards have many advantages over double-sided boards. They can be designed to be more compact, have significantly improved noise resistance, and are easier to layout.
