For the 24P (24-pin) configuration, ensure pin compatibility with your FFC/FPC connector to avoid misalignment or connection failure.
- Cable Specifications: Dimensions and Insulation
The physical and electrical characteristics of the FFC cable must align precisely with your system’s design:
- Conductor Count & Pitch: The 24P designation means 24 parallel conductors. Confirm the pitch (typically 0.5mm or 1.0mm) matches your connector specifications.
- Width & Thickness: Affects routing space and bend radius. Thinner cables offer greater flexibility but may be less durable under repeated stress.
- Insulation Material:
- PVC (Polyvinyl Chloride): Cost-effective and suitable for general-purpose, low-temperature applications (up to 105°C). Less resistant to chemicals and UV exposure.
- FEP (Fluorinated Ethylene Propylene): Offers superior heat resistance (up to 200°C), chemical inertness, and low smoke emission—ideal for harsh environments.
- PTFE (Polytetrafluoroethylene): Excellent thermal stability and dielectric properties; used in aerospace and high-reliability systems.
- Voltage Rating: The 60V rating is suitable for low-voltage signal and control circuits. Do not use in power transmission applications exceeding this limit.
- Flex Life and Mechanical Durability
FFC cables are often used in dynamic applications involving repeated bending, folding, or movement (e.g., printer heads, robotic arms, foldable displays):
- Flex life is measured in the number of bending cycles before conductor failure (e.g., 15,000 cycles, 50,000+ cycles).
- Higher flex life ratings are essential for automated equipment and moving assemblies.
- Consider reinforced edge zones or conductive shielding layers to prevent cracking and fatigue.
- Avoid sharp bends below the minimum bend radius (typically 10x the cable thickness) to prevent internal conductor damage.
The AWM 20706 standard ensures baseline durability, but performance can vary by manufacturer—opt for tested, high-cycle life versions when needed.
- Length and Connector Compatibility
Proper sizing and termination are critical for seamless integration:
