Micro board-to-board connector is a type of electrical connector designed to establish connections between two printed circuit boards or electronic components in a compact and miniaturized form factor.

Key features of micro board-to-board connectors include:

1. Miniaturized Design: These connectors are significantly smaller than standard connectors, making them ideal for applications with tight space constraints.

2. High-Density Connectors: Micro board-to-board connectors are often designed to provide a high number of contacts in a small area, making them suitable for applications requiring numerous connections.

3. Fine Pitch: They may have a fine pitch, meaning that the spacing between the connector’s contacts or pins is very close together. Common pitches for micro connectors include 0.5mm, 0.4mm, or even smaller.

4. Low Profile: Micro connectors typically have a low profile to maintain a slim form factor.

5. Versatile Configurations: These connectors come in various configurations, including right-angle, vertical, and mezzanine connectors, to accommodate different design and space constraints.

6. Surface Mount Technology (SMT): Many micro board-to-board connectors are designed for surface mount technology (SMT) assembly, which is commonly used in modern electronics manufacturing.
