FFC, FPC (Flat Flexible) Connectors

Flat flexible connectors (FFC) and printed flexible connectors (FPC) are two types of electrical connectors used in applications where space and flexibility are major considerations. FFC connectors are printed flat on both sides, while FPC connectors are printed on one side and contact on the other. Each type of connector has unique advantages and considerations when considering its use in your application, making them excellent choices for a variety of product designs.

FFC connectors are often the choice for small product applications where space is at a premium. These types of connectors are typically available with pin counts of 10-60 and are often sold as terminal strips and ribbon cables. FFC connectors are ideal for use in applications where easy connection and disconnection is desired. The connector contacts allow for a rapid connection and disconnection, making them ideal for short-term connections or use in cables that are frequently moved or adjusted. FFC connectors are generally considered to be a cost-effective option and are also resistant against vibration and shock.

FPC connectors are almost exclusively used in applications where space is an extremely limited factor. Typically, these types of connectors have pin counts of 1-40 contacts and are available in a variety of sizes and shapes. FPC connectors are ideal for use in applications where space is extremely limited, as well as those where benefit is gained from the use of integral flex circuits. The contacts are typically arranged in a symmetrical pattern, allowing for easy identification and orientation of the contact points. FPC connectors typically offer a higher degree of durability than FFC connectors, due to their integral flex circuits.

When deciding between an FFC or FPC connector of approximately the same size and pin count, the most important consideration is the application in which the connector will be used. FFC connectors are typically the better choice for applications where easy connection and disconnection is desired and where space is at a premium, while FPC connectors are better for use in applications where space is extremely limited, as well as those where benefit is gained from the use of integral flex circuits.

No matter which type of connector is chosen, both FFC and FPC connectors can be used in a variety of applications to improve efficiency and reliability. In order to assess which type is the best for use in a particular application, it is important to consider the pin count, size requirements, cost, and the design needs of the application. With the right combination, both FFC and FPC connectors can make any product or application more efficient and reliable.
