A Fine Pitch Board to Board connector is a specialized electronic component designed for connecting printed circuit boards (PCBs) with very close spacing between their contact points. These connectors are engineered to facilitate high-density connections in modern electronic devices, where space-saving and signal integrity are critical. Fine pitch connectors typically have pitch distances (the center-to-center spacing of pins or contacts) of 0.5mm or less.

Fine pitch board-to-board connectors come in various designs, such as surface mount or through-hole, and they are available in different configurations, including mezzanine connectors, stacking connectors, and more. These connectors enable the transfer of data, power, and signals between PCBs, ensuring reliable and secure connections in applications like smartphones, laptops, tablets, and other compact electronic devices.

The key features of fine pitch board-to-board connectors include precise alignment, multiple contact points for enhanced signal integrity, and various options for securing and fastening the connectors to the PCBs. Their design allows for efficient transmission of high-speed data and signals while minimizing crosstalk and signal loss. These connectors are a vital component in the miniaturization and high-performance requirements of modern electronics.
