Multilayer PCB Design – Impact of Vias on High Frequency Signal Transmission First, the basic concept of vias Through-hole (via) is an important part of the multilayer PCB, drilling costs usually account for 30% to 40% of the cost of PCB board. Simply put, every hole on the PCB can be called a hole. From […]
