Why is card edge connector called "Goldfinger"?
This is not about the famous 007 movie "Goldfinger", but rather about a card edge connector. It is a method of connecting two PCB cards, and is commonly known as "gold finger" because the surface of the PCB terminal is coated with gold or copper, which looks like finger.
Card edge connectors are widely used and easy to use. Its gold plating layer is generally 0.8u half gold plating (contacts are gold plated), or full gold plating (the entire terminal including the pins are gold plated). The thicker the gold plating, the better the anti-oxidation ability.
There are several types of card edge power connectors: Standard (SEC), SEC-II, Multi-Beam, and the newer High-Density Card Edge (HDCE).
1. SEC-II Card Edge Connector
2. Multi-Beam Power Card Edge Connector
3. High-Density Card Edge Connector
