Why Are Vias in PCBs Filled and Plugged?
Introduction Printed Circuit Boards (PCBs) are the backbone of modern electronics, providing the necessary interconnections between components. Vias are essential elements in PCBs, allowing electrical connections between different layers of the board. However, in many high-density and high-performance PCB designs, vias are intentionally filled or plugged with conductive or non-conductive materials. This process, known as…
