Introduction to Flat Flex, Ribbon Jumper Cables

Flat Flex Cables, also known as ribbon cables, consist of multiple electrical circuits on a flat, flexible, insulating substrate. This technology is often used for surface-mount, pin-through-hole, and single-layer interconnect designs. It allows for many wires in a single cable, requiring fewer connections while conserving valuable space. From the beginning, FJ-20-D-03.15-2 was designed with flexibility in mind. Construction began with a flexible substrate, mainly made from polyimide or polyethylene terephthalate (PET) materials. It also contained an onboard circuit, usually comprised of copper conductors patterned onto the substrate with a double-sided adhesive tape. The resulting cables were lightweight and highly customizable for specific applications.

Applications and Working Principle of FJ-20-D-03.15-2

The primary application of FJ-20-D-03.15-2 ribbon jumper cables is in the automotive industry. These cables are used to bridge module connections between the Body Control Module (BCM) and the ECU (Engine Control Unit). The cables are designed for applications that require high-speed ignition coil control and flex fuel sensor accuracy. FJ-20-D-03.15-2 cables offer superior shielding for a reliable connection between the modules.The circuit of FJ-20-D-03.15-2 cables consist of multiple 0.010” copper wire strands sandwiched between two 0.002” layers of dielectric material. The cable is also shielded with a grounding layer to reduce the chances of interference. The shielding provides protection from EMI/RFI noise, which can impact the performance of the modules. Furthermore, the cable has a maximum operating temperature of 85°C and a minimum bend radius of 0.08”, making it suitable for both surface mount and pin through-hole applications.Overall, FJ-20-D-03.15-2 is an ideal cable for automotive applications that require high-speed signal pass through, precise signal accuracy and shielding protection. The lower impedance of the cable provides improved signal integrity and faster signal transmission, allowing for a higher speed connection between modules.
