Flat Flex cables are complex electromechanical components that provide a variety of functions within the electronics industry, such as, high-density interconnects, flexible wiring, wire board assemblies, wire harnesses and more. For applications where space is limited, flat flex cables provide a pack-density advantage over rigid standard equivalents. The connections are provided by a flat flexible cable – flat flex jumper.

Flat flex cables are typically designed with a thin layer of cross linked polyester material that is conformal to the underlying wiring material. This material provides excellent insulation resistance to prevent short circuits between adjacent conductors as well as providing additional traction support. The individual conductors are usually formed of a solid conductor coated in a thin layer of insulation to ensure that they remain parallel to each other at all times. Depending on the application, the insulation type and thickness can be varied to suit the specific needs. The flat flex conductors are connected in series with each conductor connected to the next one in an alternating manner.

Ribbon jumpers are low profile cables used to terminate points on printed circuit boards. These cables typically run in continuous strands, either in parallel or in series, and can be folded into different configurations depending on the requirements of the device. The cables are typically connected to the board by soldering the wire strands onto the board or by using pressure-sensitive adhesive tape. The cables can also be terminated using standard termination blocks or plugs.

Ribbon jumpers are strong, lightweight, and generally remain flexible and reliable, although their lack of insulation means they are prone to interference and multiple circuit overloads. Ribbon jumper applications range from low current/high speed signal transmission to industrial control systems.

Flat flex and ribbon jumper cables are very similar in construction, both offer a flexible cable with individual conductors that run in series. Both are used in close quarters to terminate multiple points on a printed circuit and provide a reliable connection. The differences between the two come down to their insulation. Ribbon jumpers offer no insulation while the flat flex cable offers insulation and traction support.

The working principle behind both flat flex and ribbon jumpers is similar. The conductors are connected in series, with each conductor connected to the adjacent one in an alternating manner. The conductors are then routed to the connecting points on the printed circuit board and secured using solder, clips, staples, or adhesive. The conductors then provide electrical contact between the board and the device that is being connected.

Flat flex and ribbon jumper cables are versatile and can be used in a variety of applications. From connecting multiple points on a printed circuit to wiring in industrial control systems, these wires provide a reliable and strong connection. They are capable of transmitting electricity safely and are an essential part of any device or system that relies on electrical signals.
