Memory connectors have been an increasingly important part of modern computing technology, and the development of the PC Card socket, or SF9-STR1-B, has made widespread acceptance of these components possible. This article will explore the design of the SF9-STR1-B and the fields and working principles that make it applicable to modern device design.

Design

The SF9-STR1-B PC Card socket is a ZIF (zero insertion force) socket that is designed to fit with multiple types of Peripheral Component Interconnect Express (PCIe) cards. It is a low-profile socket that is able to support a single PCIe card. The socket is 0.8 mm thick and uses friction type of contacts to create a secure connection between the card and the PCB. To create a secure contact, the socket uses connections that are compliant with the PCI-SIG standards.

The SF9-STR1-B has a single row of pin headers, with 10 pins that are spaced 2.54 mm apart. The PCIe socket is designed to meet the temperature requirements for industrial applications and has an operating temperature range of -25C to +85C. It is also RoHS compliant and has a lifespan of >10,000 cycles.

Application field

The SF9-STR1-B is designed for applications that require a reliable, cost effective solution for connecting a single PCIe card. The socket is most commonly used in computers for connecting peripherals such as video cards, wireless network adapters, and sound cards. Additionally, this socket is also used in embedded applications such as medical devices, networking equipment, industrial control and automation, and aerospace applications.

Working Principle

SF9-STR1-B PCIe sockets use a zero insertion force (ZIF) design, which enables easy connection and disconnection of the PCIe card without tools. The socket has 10 pins that are evenly spaced across the length of the card. When the card is inserted into the socket, the pin headers fit into their corresponding contacts on the card. As the card is pushed into the socket, the card sits securely in the pin headers. The friction between the pin headers and the contacts on the card creates a secure contact. Once the card is inserted into the socket, the connections between the card and the socket are established and the data can be transmitted to and from the card.

The SF9-STR1-B is designed with open pin headers that allow for air flow in the socket. This helps to ensure that the card does not get too hot and helps to reduce the risk of overheating. The socket also has a latch that helps to keep the card in place and prevents it from being accidentally removed. Finally, the socket is designed with a dust cover, which helps to protect the connections against dust, dirt, and other contamination.

Conclusion

The SF9-STR1-B is a reliable, cost-effective PC card socket for connecting single PCIe cards. Its ZIF design ensures an easy connection and disconnection without the need for tools. Additionally, the socket is designed with open pin headers and a dust cover to further protect the connection and provide for better airflow. The SF9-STR1-B is designed to meet the temperature requirements of various industrial applications and is RoHS compliant. This makes it an ideal choice for many applications such as computers, medical devices, networking equipment, and more.
