Board-to-Board Connectors are electrical connectors used to join two printed circuit boards (PCBs) together, enabling the transfer of power, signals, or data between them without the need for direct wiring. They are essential in compact and modular electronic designs where space efficiency and reliable interconnection are critical.
These connectors are available in various configurations, including mezzanine (stacking), coplanar, right-angle, and parallel board layouts. They come in different pitches, heights, pin counts, and mounting styles (surface-mount or through-hole) to meet specific mechanical and electrical requirements. Many board-to-board connectors are designed to support high-speed data transmission, high pin density, and precise alignment.
