1. What materials are used in card edge connectors?
Contacts are typically made of phosphor bronze or beryllium copper, with gold or tin plating for enhanced conductivity and corrosion resistance.
-
2. How do card edge connectors ensure reliable connections?
Reliable connections are achieved through spring-loaded contacts that maintain consistent pressure against the PCB edge.
-
3. What is a keying feature in card edge connectors?
Keying features ensure proper orientation and prevent incorrect insertion of the PCB into the connector.
-
4. What is a gold finger in card edge connectors?
Gold fingers refer to the gold-plated contact pads on the PCB that interface with the connector contacts.
