FFC, FPC (Flat Flexible) Connectors

Flat Flexible Connectors (FFC, also known as FPC) are electrical connectors used for high-performance, low-profile connections between components and boards in various electronic devices like laptops, smartphones, medical equipment, industrial machinery, and more. FFCs are designed to be easily assembled and require minimal space for components, making them ideal for tight spaces. They come in single-layer and double-layer varieties, depending on the number of conductors and type of device being connected. Single-layer FFCs typically have just one conductor on each side, while double-layer FFCs can accommodate multiple conductors on either side.

FFCs are made from thin, flexible circuits that can be freely bent. They can be connected to boards through a range of methods, including through hole (TH) mounting, surface-mount (SM) lamination, and press-fit mounting. The most common form of FFC is the 12-pin version, which has a standard 0.5mm pitch and easy-to-use latch mechanism. FFCs are also available in alternative shapes and sizes, with different numbers of pins and different pitches.

FFCs offer a number of advantages over traditional wire harnesses, including a significant reduction in time, cost, and space. FFCs also reduce the risk of improper connection, since the mating between two FFCs is always correct, unlike a wire that can be misconnected. Finally, FFCs offer improved signal integrity due to the fact that they are not subject to the same types of impedance and crosstalk issues as a traditional wire harness.

In terms of operation, FFCs work by having the two sides of the FFC press together to make a physical and electrical connection. This connection is held in place by small metal latches, which press together the opposing tabs and contacts on the two sides of the FFC. When the two sides of the FFC are pushed together, a contact is made which allows electrical current to pass through. To disconnect the FFC, the latch is simply released, which allows the two sides to be separated.

Due to their unique design and flexibility, FFCs are a popular choice for use in a wide variety of applications. In the consumer electronics market, they are often used to connect the LCD and digitizer components of modern smartphones and tablets together. Additionally, FFCs are commonly used in the automotive industry for lighting systems, audio systems, and motor control. Beyond these applications, FFCs are increasingly being used for a wide range of industrial applications including robotics, machine vision, PLC control systems, and more.

Overall, FFCs offer a wide range of advantages for a variety of electrical connections. Their thin and flexible design makes them perfect for tight spaces and their simple latch mechanism makes them extremely easy and fast to use. Additionally, FFCs are a cost-effective way to create high-performance connections in a wide range of industries.
