SFV25R-1STBE1HLF application field and working principle

Flat Flexible Connectors, commonly known as "FFC," are a type of connector that is used in a wide range of applications. FFCs are typically used to join two electronic components, such as a printed circuit board (PCB) and an integrated circuit (IC). They have a flat design that allows them to be mounted in tight spaces, making them suitable for use in space-constrained applications.

Design

FFC connectors consist of two parallel rows of insulated conductors. The conductors are typically made of copper or other metal alloys with an insulation layer of polyimide film. The insulation is designed to reduce electrical noise and cross-talk, as well as protect against corrosion and other environmental effects. Depending on the application, the insulation thickness can range from 40 microns to 250 microns. Some FFC connectors are designed with a dual-row design, which allows for higher currents to pass through the connector.

Applications

FFCs are commonly used in industrial, automotive, and consumer electronics applications. They can be used to connect ICs to PCBs, as well as to connect different PCBs together. They are used in a wide range of devices including computers, phones, tablets, and audio equipment. The flexibility of FFCs make them well suited for applications where cables need to be routed in tight spaces or around corners. They are also often used in robotics applications, as they can be easily routed to the desired location without specialized tools or techniques.

Working principle

When an electrical signal is applied to an FFC connector, electrical current flows between the two conductors. This current is then transferred to the connected pins on the IC or PCB. This process is known as contact drawing and the amount of current that is drawn depends on the resistance of the connector. The FFC connector also contains a "flux" material, which helps ensure that a good connection is maintained between the two contact points. The flux also helps to reduce oxidation of the contacts, which increases the lifespan of the connector.

Conclusion

FFC connectors are highly versatile connectors that can be used in a wide range of applications. They are designed to be flexible and can be easily routed in tight places. The insulation layer helps to reduce electrical noise and improve the reliability of the connection. The flux material also helps to improve the contacts\' lifespan. FFC connectors are a cost-effective solution for connecting ICs to PCBs and other types of connections.
