2. What is the difference between a card edge connector and a backplane connector?
A card edge connector interfaces directly with a PCB, while a backplane connector provides interconnections between multiple PCBs in a rack or enclosure.
-
3. 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.
