FFC, FPC (Flat Flexible) Connectors

Flat flexible connectors, also known as FFCs and FPCs (flat panel connectors), are a type of electrical connector typically used in consumer electronics. These connectors often provide a variety of different contact arrangements and multiple configurations of mating components, as well as special features for suitable in multiple applications. They are commonly used for connecting LCDs, displays, scanners, and other electronic components to each other or to a PCB.

The 54809-1998 specification provides standardizations and performance criteria for this type of electrical connector. It describes the application field and working principle of the FFCs and FPCs.

Application Field

FFC/FPC connectors are used in a variety of different industries including automotive, aerospace, medical, consumer electronics, telecommunications, test and measurement, transportation, and industrial sectors. They can be found in a variety of electronic components, including portable or embedded devices, remote controls, power supplies, electronic toys, personal computers, communication equipment, and cameras.

Working Principle

FFC/FPC connectors are typically composed of a flexible flat cable (FFC) and a series of contacts along one, two, or four edges. The contact can be either insulative (PFC) or conductive (FFC). The cable and contacts are then interconnected with a special contact that slides along the cable when inserted into the mate connector.

FFC/FPC connectors provide the same function as traditional wires or cables, but in a compact, low-cost, and time-saving package. They are designed to reduce the number of components and wiring used in many electronic equipment. Additionally, FFC/FPC connectors have the advantage of being low-profile and flexible, allowing them to fit into tight spaces or corners.

Benefits

FFC/FPC connectors are typically more reliable than traditional cables or wires because the cables can be routed along different routes and can be accessed easily for inspection or repair. Moreover, the connectors are resistant to normal vibration or shock because of their flexible and lightweight characteristics.

The connector\'s small form factor also makes it a great choice for applications where internal wiring and routing is difficult or not possible. Additionally, FFC/FPC connectors can be very cost-effective compared to traditional connector solutions because of their reduced material and labor costs.

Conclusion

FFC/FPC connectors are commonly used in a variety of industries and applications, offering reliable and cost-effective alternatives to traditional wiring and cables. The 54809-1998 specification provides general guidance and standards for the application field and working principle of these connectors.
