Flat Flexible Connectors, often referred to as FFC and FPC, are a type of electrical connector designed for flat flexible ribbons. They offer a reliable interconnection between boards and cables by providing a secure and durable physical and electric connection. FFC and FPC connectors come in a variety of sizes and styles to meet the requirements of different application fields and working principles.
FFC and FPC connectors are used in a variety of applications, ranging from consumer electronics to industrial machinery. They can be used for inter-board, miniaturized, and mid-range applications as well as printed circuit board to backplane applications. These connectors make it possible to connect two or more boards with a simple manipulation, providing a secure electric connection.
The working principles of FFC and FPC connectors involve a combination of physical and electrical components. Physically, these connectors feature a flexible substrate that allows them to make contact with the surface of another board or cable at two or more contacting points. In order to ensure that the connection is secure, the contacts between the cable and board are enhanced by a pin retention feature. Electrically, the connector transfers the signals between the cable and board depending on the type of cable used.
In order to achieve maximum performance, it is essential that FFC and FPC connectors are selected according to their application. This will determine the size, number, and type of the contacts required. Smaller connectors are often used for inter-board applications, while mid-range and printed board to backplane applications typically use larger connectors with more contacts. The type of cable used also plays an important role in determining the performance of the connector, as certain types of cables may require special connectors and connection techniques.
FFC and FPC connectors offer a reliable, durable connection between two or more electronic components, making them an ideal choice for a wide variety of applications. Their low cost and compact size make them ideal for small scale electronics. Their flexibility allows for easily making or breaking connections, making them suitable for applications that require frequent reconfiguring. Additionally, these connectors are available in a variety of sizes to meet the needs of different applications and working principles.
