Flat Flexible Connectors (FFD and FPC) are electrical connectors used in a wide range of industries and applications. They are frequently the most reliable, low-cost and cost effective means of connecting an electrical system. They are used in such diverse applications as computers, automobiles, aerospace, medical devices, and industrial automation.

FFC and FPC connectors offer a certain degree of versatility and flexibility as they come in a variety of sizes and configurations, from ultra-miniature components like IC board socket terminals intended for miniature control equipment and robotic devices, to the high-current capacity of automotive and harsh environment connectors. They can offer resistance to shock, vibration and corrosion, as well as providing high mating cycle life and environmental sealing.

The design and construction of FFC and FPC connectors are based on a flat-flexible circuit (FFC) and a flat-polycarbonate (FPC) circuit. The FFC is constructed from a copper strip that is laminated between two layers of polyamide, such as Kapton. The FPC is constructed from an insulating support material such as polyamide, which is then coated with an adhesive to bond the copper layers together. The copper layers are attached to either side of the support substrate, forming an electrically conductive path.

An FFC or FPC will typically come in either a two or four terminals configuration. In the two terminal configuration, the terminals are connected with either two wires or two flexible flat conductors (FFC). With the four terminal configuration, the terminals are connected with four wires, each wired in parallel. The wires are usually soldered and crimped into place.

In terms of working principles, FFC or FPC connectors are designed to allow for the easy and safe transfer of signals from one device to another. They transfer the signals by providing a low-resistance connection between the two components, allowing for reliable and efficient data exchange. The electrical connection between two components is established when the FFC/FPC connectors’ terminals are engaged.

FFC/FPC connectors offer a number of advantages when compared to traditional connectors. They are generally available in a wide range of sizes and configurations, making them suitable for various applications. They are also cost-effective and offer good resistance to shock and corrosion. Furthermore, they are relatively easy to assemble and disassemble due to their simple, low-cost design.

FFC/FPC connectors have a variety of applications across various industries and fields. In the automotive industry, they are used for numerous electronic components such as airbag systems, ABS brakes, cruise control, and entertainment systems. In aircraft, they are used for a variety of components, including wiring harnesses, displays, and navigation systems. They are also used in the medical industry for a variety of medical devices and equipment, including imaging systems. Finally, they are commonplace in industrial automation systems for signal and power transmission.

In summary, FFC/FPC connectors offer an easy and reliable means for establishing an electrical connection between two components. They come in a variety of sizes and configurations, making them suitable for a number of different applications, and are cost-effective and offer good shock and corrosion resistance. Additionally, they are easy to assemble and disassemble, making them a popular choice for a variety of industries and fields.
