Flat Flexible Cable (FFC) is a type of electrical cable that is flat, thin, and highly flexible, designed for compact and high-density electronic applications. These cables are commonly used in consumer electronics, automotive systems, printers, robotics, and other devices where space-saving and flexibility are crucial.

What is FFC Cable?
An FFC cable consists of multiple flat, thin metallic conductors (usually copper) placed parallel to each other and laminated with a flexible plastic film such as polyester (PET). This flat ribbon-like structure allows for tight bends, easy routing, and minimal electromagnetic interference (EMI).
Key Characteristics:
Flat and ultra-thin design
Pitch sizes typically range from 0.5mm to 2.54mm
Lightweight and space-efficient
Easy to install and remove
RoHS compliant and halogen-free options available
Common Applications of FFC Cables
Flat flexible cables are widely used across industries due to their versatility and mechanical advantages. You’ll commonly find FFC cables in:
Laptops and tablets – connecting the keyboard, screen, and motherboard
Printers and scanners – moving parts like print heads
Automotive interiors – infotainment systems, displays, and control panels
Home appliances – touch panels, sensors, and control modules
Medical devices – compact monitors and diagnostic tools
Robotics and automation – compact signal transmission in articulated arms
FFC vs FPC: What’s the Difference?
Although often confused, FFC (Flat Flexible Cable) and FPC (Flexible Printed Circuit) differ in construction and application:
| Feature | FFC Cable | FPC |
|---|---|---|
| Structure | Flat ribbon cable | Etched copper on flexible PCB |
| Manufacturing | Stamped or laminated | Photolithographic process |
| Flexibility | High | High (but less uniform) |
| Customization | Fixed pitch & conductor count | Fully customizable |
| Cost | Lower | Higher |
Advantages of Using Flat Flexible Cable
✅ Space Saving – Ideal for compact devices with tight internal layouts
✅ Ease of Assembly – Tool-less connections for many models
✅ Flexibility – Withstand repeated bending and dynamic movement
✅ Cost-Effective – More affordable than complex circuit boards
✅ Low Impedance – Ideal for high-speed data and signal transmission
Selecting the Right FFC Cable
When choosing an FFC cable, consider the following specifications:
Pitch (distance between conductors): e.g., 0.5mm, 1mm, 2.54mm
Number of Conductors: Based on your device’s connector
Cable Length: Customized to fit your design
Termination Type: Exposed leads, stiffeners, or connectors
Bend Radius and Flex Cycles: Especially for dynamic applications
