Introduction

FFC, FPC (Flat Flexible) Connectors are widely used in today’s equipment. They are somewhat similar to wire and cable in terms of their applications, but are much more compact in size and have a much greater durability in use. This article aims to discuss the application field and working principle of FFC, FPC (Flat Flexible) Connectors.

Application Field

Flat FPC and FFC connectors are commonly used for connecting electronic components on the PCB. For example, they can be used to connect a driving motor to a power supply or a mechanical motion device to a power supply. They are also often used for connecting a computer to a printer, a laser projector, or a video imaging device. Additionally, they can be used to connect devices such as pressure sensors, humidity sensors, gas sensors, and charge sensors.

Further, FPC and FFC connectors are also commonly used for liquid crystal displays and touchscreens. This enables the device to be connected to a PC or a host via a USB port. Moreover, FPC and FFC connectors are often used for connecting the hard disk, memory, and other peripherals to a computer, thereby allowing the computer to communicate with other devices.

In addition to these applications, FFC and FPC connectors are also used in communication equipment. For example, they are used for connecting a handset to a base station, enabling the handset to send and receive signals. Further, in multimedia applications, FFC and FPC connectors are used for connecting speakers and headphones to the sound card.

Working Principle

FFC, FPC (Flat Flexible) Connectors work by combining two or more conductive surfaces with a specialized electrically conductive material. This material is typically composed of shaped metal electrodes, some of which are designed to be embedded between two adjacent surfaces. The conductive material connecting the two surfaces, which are electrically conductive, then forms a connection that enables the two surfaces to communicate with each other.

The shape of the electrodes in FFC and FPC connectors differs from application to application. Generally, the arrangement of the electrodes is typically based on the number of lanes and the number of elements that need to be connected. In particular, FFC and FPC connectors used in multimedia applications often incorporate a center conductor and two ground plates. These ground plates are typically used to shield the data lines from external noise.

As for the materials used for the construction of the FFC and FPC connectors, they are generally composed of a combination of plastic materials and metal electrodes. The plastic material that is used for the construction of the connectors is chosen for its durability and flexibility. The plastic material also serves to protect the metal electrodes from damage and corrosion, thereby ensuring a reliable connection.

Conclusion

In conclusion, FFC, FPC (Flat Flexible) Connectors are widely used in various types of electrical and electronic equipment. They can be used for connecting electronic components on the PCB, such as a computer to a printer, and for connecting a driving motor to a power supply. Further, their application also extends to multimedia devices, such as speakers and headsets, as well as communication equipment. They work by combining two or more electrically conductive surfaces with a conductive material in the form of shaped electrodes. The combination of metal electrodes and plastic materials ensures durability and flexibility for the connectors.
