Ordering a custom flexible flat cable (FFC) requires more than specifying its length and conductor count. Pitch, contact orientation, material, electrical requirements, and bending conditions all affect compatibility and performance. Providing complete specifications helps an FFC manufacturer recommend a suitable solution and reduce costly design changes.
What Specifications Are Needed for Custom FFC?
1. Pitch and Number of Conductors
Pitch is the distance between the centers of adjacent conductors. Common options include 0.5 mm and 1.0 mm, although availability depends on the manufacturer. The conductor count determines how many electrical connections the cable provides.
Tip: Check your connector's datasheet before ordering. The pitch and number of contacts must match the intended connection.
2. Cable Length and Thickness
Provide the required cable length, overall width, total thickness, and any special end dimensions. These measurements determine whether the FFC fits the available installation space and connector.
If the cable follows a curved route inside the equipment, provide a layout drawing to help the manufacturer assess the required length and clearance.
3. Contact Orientation
FFC contacts may face the same direction or opposite directions at the two ends, depending on the design. Incorrect contact orientation can prevent proper installation even when other dimensions match.
Provide connector specifications, clear photographs, or a technical drawing showing both cable ends.
4. Materials and Electrical Requirements
Specify conductor and insulation requirements, operating voltage, current, and signal type. Copper conductors and polymer insulation films are commonly used, but the appropriate materials depend on the application.
For high-speed signals, additional requirements such as impedance or signal integrity may apply. Current capacity should be confirmed based on conductor dimensions, temperature rise, and operating conditions.
5. Bending Conditions and Operating Environment
Explain whether the cable remains stationary or undergoes repeated bending. Include the expected bending radius, movement frequency, operating temperature, and potential exposure to chemicals.
Not every FFC is designed for continuous flexing. For dynamic applications, confirm the manufacturer's bending-life data and suitability before ordering.
What Should You Send to an FFC Manufacturer?
Prepare the following information before requesting a quotation:
Pitch and conductor count
Cable length, width, and thickness
Contact orientation and connector model
Material and electrical requirements
Bending conditions and operating environment
Technical drawings, samples, and order quantity
Conclusion
Choosing the right custom FFC cable starts with accurate specifications. Confirm connector compatibility, electrical requirements, and bending conditions before production. Providing drawings or samples can further reduce misunderstandings and speed up the quotation process.
