Flat Flex Jumpers, Cables (FFC, FPC)
1. What are Flat Flex Jumpers, Cables (FFC, FPC)?
FFC (Flexible Flat Cable)
Flexible flat cables are made of metal foil and insulation layers laminated together and are connected to circuits through conductive adhesives. They are thin, light, resistant to bending, and have high transmission speeds. The conductor spacing specifications range from 0.5mm to 2.54mm, which can flexibly adapt to the compact space requirements of different electronic devices and significantly reduce production costs.
FPC (Flexible Printed Circuit)
Flexible printed circuit boards use materials such as polyimide (PI) as substrates, and form customized circuit patterns through etching processes. They support three-dimensional folding and high-density wiring and are suitable for complex bending scenarios.
2. What are the Structure of Flat Flex Jumpers, Cables (FFC, FPC)?
FFC structure: Flat copper foil is sandwiched between PET insulation layers, and the regularly arranged copper wires simplify the conductor design, which is classified as a cable product.
FPC structure: It includes flexible copper foil, insulation layer, and adhesive, and uses optical imaging and metallized hole processes to achieve multi-layer interconnection, with a high process complexity.
3. What are the Differences between Flat Flex Jumpers, Cables (FFC, FPC) in Manufacturing Processes?
FFC: Mass production through a lamination process, a simple process and low cost.
FPC: Needs to go through multiple precision processes such as graphic transfer, etching, and lamination, and has a higher technical threshold.
4. What are the Performance Characteristics of Flat Flex Jumpers, Cables (FFC, FPC)?
Flexibility: FPC supports customization of any shape, while FFC can only make regular shapes.
Connection Method: FFC uses a socket connector, while FPC is compatible with sockets or flat cable clips, which is more flexible.
Temperature Resistance: The conventional temperature resistance range of both is -40 ℃ to 105 ℃, and special designs can be extended to more severe environments.
5. What are Flat Flex Jumpers, Cables (FFC, FPC) Used for?
FFC: Mainly used in scenes such as LCD panels and camera modules that require high-density connections and high-speed signal transmission.
FPC: Widely used in environments such as smartphone screens, wearable devices, automotive electronics, and medical instruments that require repeated bending.
Derivative Solution: Rigid-flexible circuit board (R-FPC) combines rigid and flexible characteristics and is used in high-precision fields such as aerospace and high-end consumer electronics.
6. Selection Recommendation for Flat Flex Jumpers, Cables (FFC, FPC)
FFC: Suitable for standardized, low-cost, and high-speed transmission scenarios.
FPC: Recommended for designs with limited space, complex bending, or customized wiring.
