What is FFC cable ?
- Number of Conductors (Pins)
- This is the total number of conductors within the cable, ranging from just a few to over 100. The conductors are also referred to as "pins." For example, an FFC cable with 20 conductors is called a 20-pin.
- The spacing of the conductors. The pitch typically refers to the distance from the center of one conductor to the center of its neighboring conductor. A single FFC can have different pitches between different conductors on the same cable, however, this is uncommon. FFC cables are available in many pitches, such as 0.500 mm, 0.625 mm, 0.635 mm, 0.800 mm, 1.00 mm, 1.25 mm, 1.27 mm, 2.00 mm, 2.54 mm, but the most common pitches are 0.500 mm, 1.00 mm, and 1.25 mm. Custom Pitch and Multiple Pitch FFC are available upon special request.
- Some cables (described as Type 1 by Würth Elektronik or Type A by Molex) have exposed contacts on the same side at each end. Other cables (labelled Type 2 or Type D) have the exposed contacts on opposite sides of the cable (so that if the cable is lying flat, one end will have face-up contacts, and the other end will have face-down contacts).
- Exposure length
- The length of the electrical contact that has been exposed at the termination of the cable.
- Most FFCs have some sort of extra material attached on the opposite side of the exposed length of the cable to facilitate ZIF or LIF connections.
- Conductors size
- The width and thickness of the conductors
Now FFC Cables are widely used in printer connections between the head and the motherboard, plotters, scanners, copiers, stereos, LCD appliances, fax machines, DVD players, and signal transmission and plate board connections. In modern electrical equipment, FFC Cables can be found almost everywhere.
