What is FFC cable? People who have never used it may be unfamiliar with this term. Ordinary users, can you tell me the definition of FFC cable? What standards does it have? What are the technical parameters of FFC cables? Below, LCSC supplier Shenzhen Jushuo Electronics will introduce it to you.
What Is FFC Cable?
FFC cable is a soft, flat cable. We can choose the number of conductors and the spacing of the conductors at will. FFC cables are to make wiring more convenient. And FFC cables can significantly reduce the size of electronic products, helping manufacturers increase production efficiency and reduce costs. FFC cables are most suitable to be placed between the motherboards of electronic products and their moving parts, between PCB boards, and as transmission lines for data between electronic devices. Therefore, FFC cables serve as signal transmission lines and connecting lines in various types of printers, scanners, copiers, audio, plotters, televisions, and other electrical equipment and their motherboards. FFC cables are ubiquitous.
FFC cables assemblies exhibit excellent flexibility, allowing their versatile application in various settings. They can be freely folded and bent, enduring millions of sliding movements without issue. Moreover, FFC cable assemblies are user-friendly, compact in size, and feature straightforward wiring procedures that are easy to understand and operate, enabling anyone to handle them independently.
FFC Cables Standards
The standards for FFC cable assemblies include the following aspects: number of PINs, spacing between FFC cable assemblies, size of conductors inside FFC cables assemblies, length of bare wires in the cable assemblies, length of reinforcing plate, etc.
1. The PIN index range of the FFC cable assemblies is between 20-100;
2. There are seven standards for the spacing of FFX cable assemblies: 0.3mm, 0.5mm, 0.8mm, 1.0mm, 1.25mm, 1.27mm, 2.54mm;
3. There are eight standards for the size of the conductors inside the FFC cable assemblies: 0.035*0.3mm, 0.05*0.5mm, 0.05*0.7mm, 0.05*1.0mm, 0.1*0.5mm, 0.1*0.7mm, 0.1*0.8mm,0.1*1.6mm;
4. The spiral length range of the FFC cable assemblies is 3-10mm;
5. The length of the reinforcing plate of the FFC cable assemblies is 3.5-20mm.
Understanding FFC Cables Technical Parameters
1. Number of conductors N: the number of copper wire conductors in the cable;
2. Spacing P: the distance between the center lines of two adjacent conductors;
3. Margin M: the distance between the centerline of the outermost conductor and the edge of the cable;
4. Full pitch TP: the distance between the center lines of the two outermost conductors, TP=P*(N-1);
5. Total width W: the distance between the two edges of the cable, W=P*(N+1);
6. Wire opening length: the average length of the exposed conductor in the longitudinal direction;
7. Total length TL: the distance between the two ends of the cable;
8. Insertion thickness TT: The thickness of the two connecting ends of the cable.
Conclusion
FFC cables are an indispensable component in electronic devices. Its ability to withstand repeated folding and bending, coupled with its user-friendly nature, ensures that FFC cables will continue to be a preferred choice for designers and manufacturers alike.
As we look to the future, the ongoing advancements in FFC standards and the development of new technical parameters promise even greater possibilities for miniaturization and efficiency in electronic design.
In conclusion, the versatility and reliability of FFC cables position them at the forefront of electronic interconnectivity, ensuring their continued relevance and growth in the rapidly evolving landscape of technology.
