Exploring the Main Connection Methods of Board-to-Board Connectors

To meet diverse design and application needs, Board-to-Board Connectors come with several connection methods. Each offers unique advantages based on stability, ease of use, and environmental demands. Here are the four most common types:

1. Plug-in Connection

This is the most widely used method, where the plug and socket are fixed on separate boards. It allows for simple insertion and removal, making it ideal for devices requiring frequent maintenance. However, repeated use can cause wear, especially in smaller pitch types like 0.8mm Board-to-Board Connectors.

2. Mechanical Connection

Using screws or other fasteners, this method provides superior vibration resistance and mechanical stability. Though it requires tools and more time to assemble, it's well-suited for environments with high mechanical stress.

3. Soldering Connection

In this method, electrical contacts are permanently joined to the PCB by soldering. It offers a highly reliable and secure connection, particularly for pcb board to board connectors used in mission-critical applications. However, it demands skilled labor and precise tools.

4. Bayonet (Twist-Lock) Connection

Quick and efficient, bayonet connections use a locking mechanism to secure the connector. It enables fast engagement and disengagement, useful in modular systems. However, over time, the lock may loosen, reducing connection stability.
