Flat Flexible Connectors, commonly known as FFC and FPC, are flat cables that are most commonly used to quickly and reliably connect components on a printed circuit board. These cables are used in a wide variety of applications, including consumer electronics, industrial machinery, and medical equipment. FFC and FPC connectors were first used in the 1960s and have since become essential components in a wide variety of products.

FFC and FPC connectors are also known as flexible flat cables, ribbon cables, flat cables, and flat-pack cables. As their name implies, they are flat in shape rather than cylindrical, which makes them highly versatile and flexible. They are convenient for tight-fitting spaces and quick connections, while saving on space, weight, and cost. They can also be stacked and secured to form more complex connections.

The basic components of FFC and FPC connectors include two primary elements: a flexible printed circuit board (FPCB) and a flat connector or jig. The FPCB is the primary portion of the system, which consists of a robust flexible layer and a printed circuit. The flat connector is used to secure the connection and ensure that it fits snugly. This element also provides strain relief to the FPCB.

FFC and FPC connectors come in a variety of sizes, shapes, and pitches. These connectors typically have between two and twelve tabs with various pitch sizes from 0.35 mm to 4.50 mm, depending on the application. The most common use for these connectors is to connect a printed circuit board to another component, or to link various components. For instance, they can be used to join a microcontroller with a digital signal processor, connecting a hard drive to a motherboard, or even connecting an LCD panel to a processor.

The working principle of FFC and FPC connectors revolves around the two primary elements: the FPCB and the flat connector. These two components fit together like a puzzle piece, with the connector complementing the board and vice versa. This connection process usually takes place using a surface mount technology, though other methods such as soldering can also be used. The electrical connection is then completed when the contact elements make contact, allowing power and data transmission between the two components.

FFC and FPC connectors are becoming increasingly popular in a variety of applications due to their flexibility, cost-effectiveness, and reliability. This type of connection technology is often used in consumer electronics, telecommunications, medical equipment, industrial machines, and other applications. They are a cost-effective alternative to more expensive connection technologies and can significantly reduce assembly time and product weight. Additionally, their flat shape allows them to be easily integrated into more complicated connections, making them a great option for applications that require a high level of precision.
