Introduction to Flat Flexible Connectors (FFC and FPC)

Flat flexible connectors, FFC and FPC connectors, are cable assemblies composed of multiple insulated conductors using all flat cable technology. These cables provide cost-effective solutions for a broad range of low-profile, short-range interconnects including electrical circuits, communication connections and data networking. FFC/FPC cables can be used in a wide range of environments, from office and computer equipment to automotive applications.

Application Fields of FFC/FPC Connectors

FFC connectors are particularly well-suited for applications requiring great mechanical flexibility, thin dimensions and miniaturized wire-to-board connections. FPC connectors are commonly found in consumer electronics, particularly computer, telecommunications, controller, sub-assembly and medical markets.  They are ideal for applications that require high-speed data transmission and flexibility, such as signal-heavy HDDs, printed circuit boards and flexible circuitry systems. The FFC/FPC cables also meet the needs for recent trends in device miniaturization and increasing interface improvements with lower manufacturing costs.

FFC/FPC Connectors Specification: FH40-30S-0.5SV(99)

FH40-30S-0.5SV(99) is a FFC/FPC flat cable connector that features a 30-way board-to-board connection. It has a 0.5mm pitch, a ribbon contact type, and has a 40mm flat cable L value. The connector also has an integrated support for small-form-factor designs (SFFs) and features a terminal-nickel plating on its surface for corrosion protection. The FH40-30S-0.5SV(99) is compatible with both FFC and FPC flat cables and is suitable for a wide range of applications with low-profile and space-saving design needs.

Working Principle of FFC/FPC Connectors

FFC/FPC connectors enable flexible and miniature interconnection between circuit boards. The FFC/FPC connectors consist of two mating parts: a connector and a flat flexible cable (FFC/FPC). The connector has contacts in the form of a ribbon that is housed in a plastic housing. The housing encloses the contacts and provides insulation and strain relief. The flat cable has metal fingers that contact the connector contacts and provide electrical connection. The flexible flat cable (FFC/FPC) allows the circuit boards to move relative to each other without breaking the electrical connection. The contacts can be soldered to the PCB, or they can be connected to a board through a surface mount technology or other automated process. The advantage of using FFC/FPC connectors is that they provide a low-profile connection which allows for a more compact and space-saving design.

Conclusion

In summary, FFC/FPC connectors, such as the FH40-30S-0.5SV(99) cable, are designed for low-profile and space-saving connection requirements. They are widely used in a broad range of applications from electronics, telecommunications, automotive to consumer products. They feature a 0.5mm pitch, a ribbon contact type, a terminal plating on the surface for corrosion protection, and an integrated support for small-form-factor designs. The electrical connection between two circuit boards is achieved through a flexible flat cable with metal fingers that contact the connector contacts. FFC/FPC connectors provide a low-profile and cost-effective solution for a wide range of interconnects.
