What Is Wire Flattening Roller?
Wire Flattening Roller is an important working part used to manufacture Flexible Flat Cable (FFC) machines. The materials are high-speed steel and cemented carbide. Its manufacturing accuracy determines the quality of FFC. Therefore, the minimum tolerance of Wire Flattening Roller is controlled at 0.001 mm, Zhuzhou Our, a high-quality supplier in China, can provide high-quality Wire Flattening Roller products.
What is Flexible Flat Cable(FFC)?
Flexible Flat Cable (FFC) can choose the number and spacing of wires arbitrarily, which makes the connection more convenient, greatly reduces the volume of electronic products, reduces production costs, and improves production efficiency. It is most suitable for moving parts and motherboards, and PCB to PCB. It is used as data transmission cable in miniaturized electrical equipment.
Common specifications are 0.5mm, 0.8mm, 1.0mm, 1.25mm, 1.27mm, 1.5mm, 2.0mm, 2.54mm and other flexible cables with various pitches.
What are the applications of Flexible Flat Cable (FFC)?
It is widely used in the connection between the print head of various printers and the motherboard, and the signal transmission and board connection of products such as plotters, scanners, copiers, stereos, LCD appliances, fax machines, and various DVD players. In modern electrical equipment, almost nowhere.
The difference between FFC and FPC?
FPC is a flexible print circuit. In terms of their manufacturing, the way they are formed is different:
- FPC is to process FCCL (flexible copper clad foil) by chemical etching to obtain flexible circuit boards with different single-sided double-sided and multilayer structures.
- FFC is a flat copper foil sandwiched between upper and lower insulating foil films. The finished product is simpler and thicker.
What are the types of FFC flexible flat cables?
Common models are as follows:
- Type A: Both ends are connected and the reinforcing plate is pasted on the insulating tape;
- Type B: Cross the reinforcing plate and paste it directly on the insulating tape;
- Type C: The reinforcing plates at both ends are directly pasted on the conductor;
- Type D: Cross the reinforcing plates at both ends and paste directly on the conductor;
- Type E: one end of the reinforcing plate is attached to the insulating tape, and the other end is directly soldered;
- Type F: The reinforcing plates at both ends are directly attached to the insulating tape, and the inner half is peeled off;
- Type G: Direct soldering at both ends.
What are the FFC technical parameters?
- Number of conductors N: the number of copper conductors in the cable;
- Pitch P: The distance between the center lines of two adjacent conductors;
- Margin M: The distance between the center line of the outermost conductor and the edge of the flat line;
- Full pitch TP: the distance between the center lines of the outermost two conductors, TP=P*(N-1);
- Total width W: the 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;
