What Is a Flexible Flat Cable?

Flexible Flat Cable (FFC) can choose the number and spacing of wires arbitrarily, make the connection more convenient, greatly reduce the volume of electronic products, reduce production costs, improve production efficiency, most suitable for moving parts and motherboards, PCB boards It is used as a data transmission cable between PCB boards and in miniaturized electrical equipment. Common specifications include flexible cables with various pitches such as 0.5mm, 0.8mm, 1.0mm, 1.25mm, 1.27mm, 1.5mm, 2.0mm, 2.54mm.

At present, it is widely used in the connection between various printer printheads and motherboards, signal transmission and board connection of plotters, scanners, copiers, stereos, LCD appliances, fax machines, various video players and other products. In modern electrical equipment, there is almost nowhere.

With bending and tensile resistance, good flexibility, cold and high temperature resistance, etc.

FPC is a flexible print circuit. From the point of view of their manufacturing, their circuit formation methods are different: 1 FPC uses chemical etching to process FCCL (flexible copper clad foil) to obtain different circuit routing. Single-sided double-sided and multi-layered flexible circuit boards. 2 FFC is a flat copper foil sandwiched between the upper and lower layers of insulating foil. The finished product is simpler and thicker. From the price point of view, naturally FFC is much cheaper, consider When it comes to production costs, more companies prefer to use FFC related design FFC flexible cable industry general specifications: P × N × TL × TYPE × (S1 / S2 / S3 / S4) (CT × CW) Pitch Pins Total Type Strip Length Supporting Tape Conductor Conductor Length Length Thickness Width Example S1 / S2: Stripping Length S3 / S4: Reinforcing Board Length Conductor Thickness Width Example: 0.5 × 45 × 300 × A (4/4/8/8) (0.035 × 0.30), which means 0.5mm pitch, 45 positions, total length of 300mm, same direction, 4mm cable openings on both ends, 8mm reinforcement plate length, copper wire specifications 0.035 * 0.30 Model of FFC flexible cable, and this specification is mainly applicable to LCD.

Common types of flexible flat cables are as follows:

Type A: the two ends are connected and the reinforcing plate is pasted on the insulating tape; type B: the reinforcing plate is cross-linked and pasted directly on the insulating tape; type C: the two-end reinforcing plate is directly pasted on the conductor; type D: two The end reinforcing plate is directly pasted on the conductor across; E type: one end of the reinforcing plate is pasted on the insulating tape, and the other end is directly soldered; F type: the two ends of the reinforcing plate are pasted directly on the insulating tape, and the inner half is peeled off; Type G: Solder directly at both ends.

FFC Technical parameters of flexible flat cable FFC:

Number of conductors N: the number of copper conductors in the cable; Pitch P: the distance between the centerlines of two adjacent conductors; Margin M: the distance between the centerline of the outermost conductor and the edge of the cable: full pitch TP : Distance between the centerlines of the two outermost conductors, TP = P * (N-1); total width W: distance between the two edges of the cable, W = P * (N + 1); total length TL: The distance between the two ends of the cable; Insertion thickness TT: the thickness of the two connecting ends of the cable;
