Flat Flex, Ribbon Jumper Cables

Flat flex interconnects can be used to join two PCBs, while ribbon jumper cables are used to join electronics components together within the same PCB. While both are composed of similar cable materials and employ the same basic techniques during the wiring process, there are some notable differences between the two.

FJ-10-D-03.00-4 Application Field and Working Principle

The FJ-10-D-03.00-4 flat flex jumper cables feature an overall width of 10mm and ribbon length of 3.00 meters. They come in a wide range of lengths, strand sizes, and colors—including blue and yellow—and are suitable for a variety of applications, such as:

• Connecting primary power rails of a microprocessor
• Signal and data communications
• Routing power to computers’ peripherals
• Raising electrical circuit ground connection

This type of cable is designed with a split center conductor, which is made from zinc-coated copper. The conductor is then wrapped in a ferromagnetic material, such as laminated ferrite, to reduce interference. The material also helps reduce the EMI (electromagnetic interference).The dielectric layer is made from a special polyimide film. The dielectric layer provides additional shielding and insulation to prevent the cables from shorting. It also helps reduce the amount of power that must be transmitted through the cable, which helps reduce power consumption.The outer jacket of the cable is made from a flame-retardant PVC material. This jacket helps to protect the cable from external elements and provides additional strain relief.

Installation Procedure

Installing flat flex jumper cables is a straightforward process. The first step is to measure and mark the cable to the appropriate length. Next, you will need to cut the ribbon cable to the required length. For this, it is recommended to use a wirecutter and Diagonal Pliers. This will ensure a clean cut and will help to avoid damaging the wires. Once the cable is cut to the desired length, the ends need to be prepared.To do this, each end must be stripped of its outer PVC jacket and ferrite core. The PVC jacket is relatively easy to remove with the help of a wire stripper. The ferrite core, on the other hand, can be a bit more difficult to remove and requires some experience.Once the outer jackets and ferrite cores of the cable have been removed, the wires of the cable can be bent into the desired shape. This is known as the “terminating” process, and it involves forming the ends of the cable into an appropriate electrical connection. Once this is done, the cable ends can be soldered to the desired PCB.

Conclusion

Flat flex and ribbon jumper cables are often used for their ability to transmit electrical signals from one location to another. This allows for a reliable connection between two separate circuits, and can be used in a variety of applications. The FJ-10-D-03.00-4 cable, in particular, is designed with a special split conductive center and shielded dielectric layer that helps reduce interference. Installation is relatively simple, although it requires some experience to properly terminate the cable ends.
