Board-To-Board Connectors（V/W/X：XH）
A board-to-board connector is a component that connects or disconnects a circuit board and components, etc., by attaching it to the circuit board. Mainly used for notebook computers, mobile devices, and information and communication devices, board-to-board connectors include vertical connections, stacking connections, horizontal connections, etc. and various combinations of connectors are possible by combining connectors. Some have various functions, such as being vibration-resistant, impact resistant, having a high retention of connection parts, etc. Many connectors are square, and male, female and male / female are also used, so it is necessary to select a connector according to the circuit board and components to be connected.

FAQ Board Connectors
- Question: What factors should be considered when selecting a board-to-board connector?
- Answer: When selecting a board-to-board connector, consider:
1. Pitch: Ensure the connector's pitch matches the spacing between corresponding points on the boards.
2. Number of Contacts or Pins: Select a connector with the appropriate number of contacts for the application.
3. Voltage and Current Ratings: Consider the connector's capacity to handle the electrical requirements of the system, for example High current board-to-board connectors
4. Size : physical dimensions like height and orientation, for example, low profile or right angle PCB board connectors, should match your design to maintain a compact and efficient assembly.
5. Environmental Conditions: Consider factors like temperature, humidity, and exposure to chemicals to ensure the connector can withstand the intended operating environment. - Question: How do you ensure a secure connection with board-to-board connectors?
- Answer: To ensure a secure connection, consider
1. Robust Locking Mechanisms: Select connectors with sturdy locking features to ensure a secure and stable connection.
2. Adequate Contact Pressure: Choose connectors that provide sufficient contact pressure, preventing unintentional disconnections and maintaining a reliable electrical connection.
3. Reliable Solder Profile: For surface mount board interconnects, prioritize connectors with a dependable solder profile to establish a strong bond with the PCB.
4. Consider Environmental Factors: Evaluate the application's environmental conditions and, if exposed to moisture or other elements, opt for waterproof board-to-board connectors to enhance durability and prevent damage. - Question: What are the differences between mezzanine, coplanar, and backplane board-to-board connectors?
- Answer: 1. Mezzanine Connectors:
• Application: Join parallel PCBs in compact spaces.
• Characteristic: Small stacking height.
• Usage: Common in applications where space efficiency is crucial.
2. Coplanar Connectors:
• Application: Facilitate edge-to-edge connections on the same plane.
• Characteristic: Allow for flexibility in board orientation.
• Usage: Often used in modular designs.
3. Backplane Connectors:
• Application: Connect multiple PCBs within a chassis.
• Characteristic: Provide a higher number of connections.
• Usage: Ideal for scalable and complex systems, especially those requiring high-speed electronic board connections. - Question: Can you explain the role of pitch and stacking heights in board-to-board connectors?
- Answer: Pitch in board-to-board connectors denotes the distance between contact points, influencing density. A smaller pitch allows more contacts in a given space, crucial for compact designs. Stacking height represents the vertical space occupied when connectors are mated. It affects the overall system profile and is pivotal for applications with tight space constraints. Engineers optimize pitch for connectivity and stacking height for space efficiency, ensuring an ideal balance for electronic designs where minimizing size is essential.
- Question: What are the latest trends in miniaturization for board-to-board connectors?
- Answer: The latest trends in miniaturization for board-to-board connectors involve reduced pitch sizes, such as 0.4mm or even smaller, enabling higher contact density in limited spaces. Additionally, advancements in materials and manufacturing techniques contribute to smaller connector footprints. Robust and compact designs, like micro connectors and low-profile options, cater to applications with stringent size constraints, such IoT devices.
- Question: How do board-to-board connectors cater to the high-speed data transfer requirements?
- Answer: Board-to-board connectors meet high-speed data transfer demands by employing impedance matching, shielding against electromagnetic interference, and supporting high data rates (Gbps/Tbps). Differential signaling reduces noise susceptibility, while minimized crosstalk enhances signal integrity. These connectors play a pivotal role in various electronic applications, ensuring efficient and stable data transmission across interconnected boards.
