Explanation of 5 Advantages of FFC Cable Arrangement

Introduction to FFC cable arrangement

FFC cable is a kind of soft flat cable. We can freely choose the number of wires and the spacing of wires. FFC cable is to make the connection more convenient, which can greatly reduce the volume of electronic products, help businesses improve production efficiency, and help manufacturers reduce production costs. FFC cable is most suitable to be placed between the main board of electronic products and their moving parts, between PCB boards and as a data transmission line between electronic devices. Therefore, FFC cable is widely used in signal transmission lines and connecting lines between various types of printers, scanners, copiers, audio, plotters, televisions and other electrical equipment and their motherboards. It can be seen everywhere in the contemporary era of science and technology.

FFC cable arranger has excellent flexibility, can be flexibly applied to various occasions, and can be folded and bent freely. It is not a problem to slide thousands of times. Not only that, FFC cable setter is also convenient for suppliers to use, the volume is also very small, the wiring program is very simple and easy to understand, and everyone can operate by himself.

The convenience brought by FFC arrangement to production

The FFC wiring board was originally designed to replace the larger wire harness because of its small volume and light weight. In the current cutting edge electronic device assembly board, FFC cable arrangement is usually the only solution to meet the requirements of miniaturization and mobility. FFC (sometimes called flexible printed circuit) is to etch copper circuit or print polymer thick film circuit on polymer substrate. For thin and light devices with compact and complex structure, the design solutions include from single-sided conductive lines to complex multi-layer three-dimensional assembly. The total weight and volume of FFC are 70% less than that of traditional round wire harness. FFC cable can also increase its strength by using reinforcing materials or lining plates to obtain additional mechanical stability.

Standard for FFC cable arranger

The standards of FFC cable arranger include the following aspects: number of pins, spacing of FFC cable arranger, size of conductor inside FFC cable arranger, length of bare wire of cable arranger, length of reinforcing plate, etc.

1. The pin index of FFC cable arranger ranges from 20 to 100;

2. There are seven standards for the spacing of FFX cable arranger: 0.3mm, 0.5mm, 0.8mm, 1.0mm, 1.25mm, 1.27mm and 2.54mm;

3. There are eight standards for the size of the conductor inside the FFC stringer: 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 FFC cable setter is 3-10mm;

5. The length of reinforcing plate of FFC cable arranger is 3.5-20mm.

Explanation of 5 advantages of FFC cable arrangement

1. FFC cable has higher assembly reliability and quality. FFC cable reduces the hardware required for internal connection, such as solder joints, trunk lines, backplane lines and cables commonly used in traditional electronic packaging, so that FFC cable can provide higher assembly reliability and quality. Due to the traditional internal hardware composed of complex multiple systems, it is easy to show a high component dislocation rate during assembly. Ping. Wu, marketing manager of eecx electronic products division, said, "FFC cable has low stiffness and small volume. It is precisely because the volume of FFC cable board components is small, so there is less data used." with the presentation of quality engineering, a thin flexible system is designed to be assembled in only one way, Then it eliminated many compensation errors related to independent wiring engineering.

2. FFC cable can move, bend and twist without damaging the wire, and can comply with different shapes and special package sizes. The only limitation is the volume space problem. Because it can withstand millions of dynamic bending, FFC cable can be well used in the internal system of continuous or periodic movement, and become a part of the function of the final product. The solder joint on rigid pcb will fail after hundreds of cycles due to thermal mechanical stress. Andy, product manager of eecx electronic, said, "some products that require electrical signal / power movement and have a small shape factor / package size benefit from FFC cabling.

3. FFC cable has small volume and light weight. The gray FFC cable board was originally designed to replace the larger harness wires. In the current cutting edge electronic device assembly board, FFC cable is the only way to meet the requirements of miniaturization and mobility. FFC cable (sometimes referred to as flexible printed circuit) It is to etch copper circuits or print polymer thick film circuits on polymer substrates. For devices that are thin and light, compact and complex in structure, the design treatment scheme includes from single-sided conductive lines to complex multi-layer three-dimensional assembly. The total component and volume of FFC wiring are 70% less than that of traditional round wire harness methods. FFC wiring can also be reinforced by using materials or lining plates The method adds its strength to obtain additional mechanical invariance.

4. FFC cable has excellent electrical function, dielectric function and heat resistance. The CEO of LT electronic said: "low dielectric constant allows rapid transmission of electrical signals; Superior thermal function makes the element easy to cool down; A higher glass transition temperature or melting point allows the element to operate at a higher temperature.

5. FFC cable can be moved, bent and changed without damaging the conductor. It can obey different shapes and extraordinary packaging dimensions. The only limitation is the volume space problem. Because it can accept millions of dynamic bends, FFC cable can be well used in the internal contact system of continuous activities or scheduled activities, and become a part of the function of the end product. The effect of mechanical stress on the solder joint on the rigid pcb will fail after hundreds of cycles. Jenny, product manager of eecx, said: "some products with small shape factor / package size benefit from FFC wiring.

Application of FFC cable

At present, it is widely used in the connection between the print head and the main board of various printers, the signal transmission and board connection of plotters, scanners, copiers, audio, liquid crystal appliances, fax machines, various DVD players and other products. It is almost nowhere in modern electrical equipment.

Common models:

Type A: both ends are connected and the reinforcing plate is pasted on the insulating adhesive tape;

Type B: the reinforcing plates are pasted directly on the insulating adhesive tape;

Type C: the reinforcing plates at both ends are directly pasted on the conductor;

Type D: the reinforcing plates at both ends are cross pasted directly on the conductor;

Type E: one end of the reinforcing plate is pasted on the insulating tape, and the other end is directly soldered;

Type F: the reinforcing plates at both ends are directly pasted on the insulating adhesive tape, and half of the interior is peeled off;

Type G: solder directly at both ends.
