Vias are small conductive holes that interconnect the different layers of a printed circuit board. Created by drilling and copper plating, they provide a reliable electrical pathway for signals and power.

This technology is essential for constructing complex, multilayer PCBs used in modern electronic devices. In addition to establishing electrical connections, vias also play a role in effective thermal management.

Key features of vias include:

• Reliable interlayer connectivity for both internal and external circuits.
• Enhanced signal integrity with minimized interference.
• Efficient distribution of heat and electrical current.

Ongoing innovations in PCB manufacturing ensure that vias continue to meet the increasing demands of high-speed and miniaturized electronic systems.
