Flexible flat cable (FFC cables) is a new form of data cable made of insulated materials and thin tin-plating flat copper by means of prodution pressing via high technology automatization devices. This 22pin FFC cable is quite flexible, bendable, foldable, thin, tiny, and it's easy to connect and assemble and disassemble. Other than that, FFC cable is able to solve electronmagnetic interference. There are free options for the number of wires and their normal pitches. FFC gives great conveniences for connection, what's more, descreases electronics' volume, reduces the cost of production and increases the productivity. FFC can be used in the connection between mobile components and mainboard, connection between PCB and PCB. In addition, FFC acts as a data transmission cable in some miniaturization electrical equipments.
