FFC, FPC (Flat Flexible) Connectors

The FB8S039JA2R2000 is an FFC, or Flat Flexible Connector, that is specially designed for high reliability connections between wire and cable assemblies and bowed PCBs. The standard FPC design includes two rows of round contacts that are held together with tape or a locking tab. Each round contact is typically made of nickel-plated steel so they are durable and rust-resistant.

These connectors are ideal for applications where space and weight is of concern or when the installation environment is limited. They are also commonly used in a variety of consumer electronics because they hold up to bending and flexing during product assembly and installation. These connectors come in a variety of sizes and can range from very small to very large depending on the application.

Application Field

The FB8S039JA2R2000 FFC Connector is designed to be utilized in consumer electronics applications requiring a high-reliability connection. It is especially well-suited for applications that require a high amount of bending, flexing, and vibration during operation. Most commonly, these types of connectors are used in laptop computers, DVD players, LCD TVs, video cameras, automotive electronics, and handheld devices.

The FB8S039JA2R2000 is also ideal for flex and rigid-flex applications. This type of connector is typically used for data signal, power, and coaxial transmission. Moreover, applications that require board-to-board connections can make use of FFCs to link two PCBs that are placed close together. Highly reliable low-loss electrical connections are achieved with the use of FFCs due to their close proximity.

Working Principle

FFC connectors use a pin and socket arrangement in the contact workfaces, which allows a secure high-reliability electrical connection between the contacting parties. An FFC connector is inserted in between two surfaces, which requires connecting two PCBs or cables on either side. The FB8S039JA2R2000 is designed with two rows of round contacts, each with a center pin and socket on the end, which provides a secure thread-down feature. When two PCBs are inserted between the two rows of contacts, the center pin and socket on each contact is engaged. This thread-down feature ensures that the connection is secure and reliable.

In addition, FFC connectors are designed with a tape or plastic locking tab, which keeps the two rows of contacts in place. This design element helps to prevent accidental disconnection of the two sides during operation. An FFC connector also typically includes flat feet, which ensures that the contacts have good ground contact when they are connected.

Conclusion

The FB8S039JA2R2000 is an FFC connector that is designed to provide high reliability connections between wire and cable assemblies and bowed PCBs. It has a pin and socket contact workface arrangement, which allows a secure and reliable electrical connection between the two surfaces. This type of connector is ideal for applications that require a high amount of bending, flexing, and vibration during operation, and has a wide range of applications in consumer electronics as well as flex and rigid-flex designs. Lastly, the small size and lightweight design make FFCs perfect to be used in applications where space and weight is of concern.
