FFC Connectors

FFC connectors (or flat flexible connectors) are a type of electrical connector used to connect two strips of flat, flexible conductors. The connectors provide a fast, cost-effective and reliable way to connect same or different substrates on printed circuit boards in a variety of industrial applications. These connectors are designed to provide flexible connectivity solutions for a variety of signal and power supplies in mobile, hand-held and low-profile devices. The use of FFC connectors is growing due to their small physical size and economical cost, which make them suitable for devices where space is a premium.

Working Principle

FFC connectors are made from a flexible, flat cable that features individual copper pins at either end. The pins are crimped onto the cable and the insulation is usually pre-located between the pins. The pins are soldered to their respective substrates. When the cable is mated with its counterpart, the pins fit into slits or holes in the cable, allowing for a secure connection. The connectors are designed for a specific pitch, which is the distance between the two rows of pins.

FFC connectors come in different types such as board-to-board, board-to-cable and cable-to-cable. In addition, they come in different sizes, orientations and pin numbers. The connectors may also feature a snap-lock system that facilitates a quick and easy connection. The connectors are available in different contact-plating options such as gold plating, tin plating and nickel plating.

Application Field

FFC connectors are widely used in computers, consumer electronics, automotive, aerospace, medical and communication applications due to their ability to provide high-speed signal transmissions in very small spaces. They are ideal for low profile and miniaturized devices such as digital cameras, cell phones and PDAs. FFC connectors are also used in flat panel displays, flat panel monitors, digital video recorders and LCD televisions.

FFC connectors are also used to interconnect memory cards, graphics cards and graphics modules to motherboards. They are found in game controllers, medical devices and computers, as well as in military and aerospace applications. Additionally, they are used in imaging equipment, testing instrumentation and measuring instruments.

In short, FFC connectors offer design engineers a dependable solution for creating high-speed connections in a wide range of applications. They provide superior electrical performance, improved system reliability and high-grade protection for signal transmission.
