Card edge connectors mate directly with the PCB edge, whereas headers require a separate male connector soldered to the board. Card edge is generally more space-efficient for modular systems.
Card Edge Connectors Component Intelligence
High-density board-to-board interconnects for modular PCB architectures.
What are Card Edge Connectors components?
Card edge connectors interface directly with PCB gold fingers, eliminating the need for a mating header. They are critical for modular designs, offering high contact density and cost-effective board-to-board connections in backplane and industrial computing systems.
How to Choose Card Edge Connectors Components
Selecting the right card edge connector requires balancing mechanical fit with electrical signal requirements.
Contact Pitch
Standard pitches range from 0.050" to 0.156". Ensure the pitch matches your PCB gold finger layout precisely.
Mounting Style
Choose between through-hole, surface mount (SMT), or press-fit based on your PCB assembly process and mechanical stress requirements.
Contact Plating
Gold plating is essential for high-cycle applications to prevent oxidation and ensure low contact resistance over time.
Polarization
Use polarizing keys or notches to prevent incorrect board insertion, which can cause catastrophic short circuits.
Current Rating
Verify the current rating per contact to ensure the connector can handle your system's power distribution needs.
