Product Assembly Structure
Flat Flexible Cable (FFC) were adopted in 1970 as a standard interface to jumper between printed circuit boards. It is made up of thin rectangular tin-plated copper conductors laminated between two layers of polyester insulator tape. These conductors are left uncovered on each end to make electrical contact with the connector. A stiffener is bonded to the cable end which provides mechanical stability for the exposed conductors during mating and unmating. This type of cable is used when a straight one-to-one connection is required.

Characteristic ImpedanceDifferential tracesUse controlled impedance FFC cable line that match the differential impedance of your transmission medium and termination resistor. Route the differential pair traces as close together as possible and as soon as they leave the IC. This helps to eliminate reflections and ensures that noise is coupled as common-mode. Signals that are 1 mm apart radiate far less noise than traces 3 mm apart, as magnetic field cancellation is much better with the closer traces. In addition, noise induced on the differential lines is much more likely to appear as common-mode which is rejected by the receiver.

Dielectric Constant ControlDielectric constantA material is classified as “dielectric” if it has the ability to store energy when an external electric field is applied, If an AC sinusoidal voltage source V is placed across the same capacitor, the resulting current will be made up of a charging current Ic and a loss current Il that is related to the dielectric constant. The losses in the material can be represented as a conductance (G) in parallel with a capacitor (C).

� Space SavingIt can be stacked in layers allowing even more signals to betransmitted without increase in size.
� Small DimensionsDue to the increased surface area of flat conductors, it has far more current capacity than equivalent round conductors, which maximizes heat dissipation.
� Excellent FlexibilitySuperior bendability similar to flex circuits (FPC), but better flexibility than other like PVC cables.
�Saving Process CostEasy insert to and pull out from connector and/or solder directly onto PCB.
�Saving Material CostApplicable as FPC replacement, with more cost effective compared with FPC.
�Halogen FreeAll Assembly parts can matching Halogen Free Standard
