Introduction of card edge connector?
Release time: 2023-02-07
The card edge connector is a method to connect two PCB boards. Because the PCB terminal surface is plated with gold or copper, it is like a finger, so it is commonly known as "golden finger". Card edge connectors are versatile and easy to use. In order to let more people familiar with it, the next small series for everyone to introduce some of the basic information about the card edge connector it.

The gold-plated layer of the card edge connector generally has 0.8u half gold-plated (contact gold-plated) and full gold-plated (the entire terminal includes pin gold-plated). The thicker the gold plating layer, the better the oxidation resistance. The card edge connector is used to insert into the card slot and contact the metal spring in the card slot, similar to the placement of fingers. Because this type of design requires high wear resistance and conductivity of the pad surface, it will be plated on the surface of the mat. There is a layer of nickel, a layer of gold, so commonly known as gold finger. Our company adheres to the principle of customer first and quality first, as always, to provide better products and better services for all enterprises, and is willing to make greater contributions to the country's environmental protection. This type of card edge connector is designed for high signal integrity (SI) on printed circuit boards (PCBs). Our card edge connectors increase PCB space by providing high-performance reliability and design flexibility for PCIe protocol solutions. The product portfolio includes rectangular surface mount sockets with 52 contacts (for Express mini-cards) or 76 contacts (for display mini-cards). The lock is available for the selected height. Some products in this category may support multi-function expansion cards and modules, including: WiFi, Bluetooth, GNSS, Near Field Communication, Wireless Gigabit Alliance (WiGig).
There are several main specifications for card edge connectors: standard (SEC), SEC-II, multi-beam, and newer high-density (HDCE). Card edge connectors are one of the classic connector categories widely used in the data and communications industry. These card edge connectors connect to the edge of the PCB through a single female connector, saving space and cost. PCIe®standards that define the reliability and performance of card edge connectors. From standard products to high-speed and high-power products, Amphenol provide a variety of card edge solutions for different applications. We offer a complete line of highly efficient card edge connectors to meet your application and design requirements.
