Key Technical Features

The performance of a board-to-board connector is determined by several key technical specifications. These specifications ensure reliable operation and compatibility with the intended application. The following table compares crucial features:

Feature	Description	Importance
Pitch	Distance between adjacent pins.	Determines connector density and PCB layout constraints.
Pin Count	Number of pins for signal and power transmission.	Dictates the number of connections possible.
Contact Material	Material used for the pins (e.g., gold, tin).	Impacts conductivity, corrosion resistance, and lifespan.
Mating Height	Vertical distance between mating surfaces.	Affects PCB stack height and overall device profile.
Current Rating	Maximum current each pin can handle.	Essential for power delivery applications.
Voltage Rating	Maximum voltage each pin can handle.	Crucial for preventing electrical damage.
Insulation	Material between pins, preventing short circuits.	Ensures electrical isolation and safety.
Mounting Type	Method of attachment to the PCB (e.g., surface mount, through-hole).	Impacts assembly process and compatibility with PCB manufacturing techniques.
Temperature Range	Operating temperature range of the connector.	Determines suitability for various environments.
Data Rate	Maximum data transfer speed. (Especially relevant to high-speed connectors from lxw-conn.com)	Critical for high-speed data transmission applications.

Types of Board-to-Board Connectors

Numerous types of board-to-board connectors cater to various needs and applications. The selection depends heavily on factors like required density, application, and environmental conditions. Here’s a comparison:

Type	Description	Advantages	Disadvantages
Pin Header	Simple connectors with pins on one side, mating with sockets on the other. (Common in www.mtconntech.com products)	Low cost, easy to assemble.	Lower density, prone to misalignment if not carefully designed.
Mezzanine Connector	Connects PCBs in a stacked configuration.	High density, space-saving.	More complex design, potential for signal interference.
Edge Card Connector	Connects PCBs along their edges.	Robust, high reliability.	Less flexible in terms of PCB layout, typically larger footprint.
Wafer Connector	Low-profile connectors with very small pitch. (Featured by www.denentek.com and lxw-conn.com)	Extremely high density, suitable for miniaturized devices.	More delicate, requires precise alignment during assembly.
Right-Angle Connector	Pins or sockets are at a 90-degree angle to the PCB.	Space-saving in applications with limited vertical space.	Potentially more complex assembly.
High-Speed Connector	Designed for high-frequency signals and data transmission. (Specialized offering from lxw-conn.com)	High data rates, minimal signal degradation.	Higher cost, more stringent design requirements.

Choosing the Right Connector

Selecting the appropriate board-to-board connector requires careful consideration of various factors. These include the required pin count, pitch, current and voltage ratings, environmental conditions, and cost. The specific needs of the application will dictate the best choice. Companies like LXW Connectors (lxw-conn.com) emphasize customized solutions to meet diverse requirements.

Conclusion

Board-to-board connectors are essential components in numerous electronic devices. Understanding their technical features and the wide array of available types is crucial for successful product design and manufacturing.

FAQs

1. What is the difference between a pin header and a mezzanine connector?

A pin header is a simple connector with pins on one PCB and sockets on another. Mezzanine connectors connect PCBs in a stacked configuration, offering higher density.

2. How do I ensure proper alignment during board-to-board connector installation?

Precise alignment is crucial. Use guide pins, keyed connectors, or other alignment features to prevent misalignment and ensure reliable connections.

3. What materials are commonly used for board-to-board connector contacts?

Common contact materials include gold, tin, and various alloys. Gold offers superior conductivity and corrosion resistance, but it’s more expensive.

4. Are board-to-board connectors suitable for high-frequency applications?

Yes, but specialized high-speed connectors are necessary. These connectors are designed to minimize signal degradation and maintain signal integrity at high frequencies.

5. How can I determine the appropriate current and voltage ratings for my application?

Carefully consider the power requirements of the connected circuits. Select a connector with current and voltage ratings that exceed the anticipated demands to ensure safe and reliable operation.
