Flat cables are used to connect peripherals inside the computer. They consist of highly stranded, individually insulated conductors that are laid in parallel and then fused into a flat, flexible ribbon structure. The flat cable distributes the mechanical load over the total bearable width, improves heat dissipation and eliminates the need for large conductors. Unlike traditional round wire cables, flat cables do not require redundant insulation materials, fillers and tapes. Because the spacing of the conductors is fixed and the geometry is constant, electrical characteristics such as impedance, capacitance, time delay, crosstalk, and attenuation remain unchanged. The important specifications of flat cables include the number of conductors, cable width, cable spacing, rated voltage and rated temperature.
