Board-to-Board Connectors

Molex Board-to-Board Connectors are available in a variety of configurations, offering an expansive array of pitches and stacking heights. The printed circuit board (PCB) is a foundational staple in the electronics industry, and with continuing trends toward miniaturization, designers need a more diverse range of solutions for creating dependable PCB connections. To fit a range of applications, Molex Board-to-Board Connectors include mezzanine, backplane, coplanar, and more. These connectors are ideal for microminiature and high-power applications.
