Introduction to Flat Flexible Cable ffc
Flat Flexible Cable ffc (FFC cable), sometimes also called Flexible Printed Circuit (FPC), is a flat cable made of a multi-strand copper wire conductor wrapped with insulating material and pressed by a high-tech automated equipment production line through a sheath material. It has the advantages of softness, free bending and folding, relatively thin thickness, small size, simple connection, easy disassembly, etc. The number and spacing of wires can be arbitrarily selected to make wiring more convenient, greatly reduce the volume of the product, reduce production costs, and improve production efficiency. It is suitable for data transmission cables or power transmission in electrical equipment. Common specifications include 0.5mm, 0.8mm, 1.Omm, 1.25mm, 1.5mm, 2.0mm, 2.5mm and other flexible cable with various spacings. The design of FFC allows it to bend and fold in a small space, which is very suitable for use in environments that require frequent movement or limited space.
Flat Flexible Cable ffcs are used for power connections and control signal lighting of various mobile power devices in industries such as lifting, transportation, machinery, electrical, mining, etc. with working voltages below 450/750V and ambient temperatures of -70~260℃.
It has the following characteristics: Nitrile compound is used for insulation and sheath. Improve the softness and corrosion resistance of the cable. TST CABLES can customize various specifications of Flat Flexible Cable ffcs according to customer needs, and add steel wire ropes or other load-bearing elements on both sides of the core.
The wide application of FFC cables is due to its light, flexible, efficient transmission characteristics, and ability to adapt to complex space and mobile needs. With the continuous advancement of technology, FFC will continue to play a key role in more innovative fields.

Flat Flexible Cable ffc (FFC) structure and materials
Flat Flexible Cable ffc (FFC) materials and structure
The main materials of FFC cable include conductor, insulation layer and protective layer. The basic structure of FFC consists of conductor layer and insulation layer, where the conductor layer can be single layer or multi-layer, and the insulation layer is wrapped around the outside of the conductor layer to form a flat cable structure. In some high-performance FFCs, additional shielding layers and reinforcement layers may also be included to provide better electromagnetic compatibility (EMC) and mechanical protection.
Conductor layer: Usually a thin wire made of copper, used to transmit electrical signals. The thickness and width of the conductor layer can be customized according to different application requirements.
Insulation layer: Covering on the conductor layer, it plays the role of electrical isolation to prevent short circuit. Common insulating materials include polyimide, polyester (PET), polyvinyl chloride (PVC), etc.
Protective layer: In some FFCs, there is an additional protective film to increase the mechanical strength and durability of the cable and protect the conductor and insulation layer from external damage.
Connector: Both ends of the FFC are usually equipped with special connectors for connecting to the motherboard or other circuit boards of electronic devices for quick plugging and unplugging.
Conductor material:
The most commonly used is copper, especially high-purity oxygen-free copper (OFC), because of its good conductivity and flexibility. The conductor is usually in the form of multiple strands of fine copper wires twisted together to enhance the softness and tensile strength of the cable.
Insulation layer material:
Polyimide: It has excellent thermal stability, chemical stability and mechanical strength, and is suitable for high temperature environments.
Polyester (PET): It has low cost and is suitable for medium temperature and non-extreme environments.
Polyvinyl chloride (PVC): It is used in some non-high temperature applications, such as internal connections of household appliances.
Silicone: It has good heat resistance and flexibility, and is suitable for occasions requiring high flexibility and temperature resistance.
Protective layer material: usually polyimide or polyester film, sometimes rubber or silicone is used to increase the mechanical strength and environmental resistance of the cable.
Flat Flexible Cable ffc (FFC) temperature range
The temperature range of Flat Flexible Cable ffc (FFC) mainly depends on the selected insulation material and protective layer material. For example:
Polyimide cable (Polyimide): The operating temperature range is usually -55°C to +200°C or above, and some special grades can reach +260°C.
Polyester cable (PET): The operating temperature range is about -40°C to +105°C.
Polyvinyl chloride cable (PVC): The operating temperature range is usually around -20°C to +80°C.
