Flat Flexible Connectors (FFC/FPC) are a type of compact and cost-effectively manufactured printed circuit board connectors. Having low profile and featuring a wide range of size options, these electrical connectors are ideal for use in high-density connection applications. The FFC/FPC technology is especially common in consumer electronics, medical, automotive and industrial applications.

The FFC technology utilizes the connection between conductive flat cables and printed boards or connectors. Such assemblies can be completed using a variety of connection methods, depending on the application. These include reciprical and/or pre-assembled FFC/FPCs. The setup can be designed to either universally fit any individual application or to custom specifications depending on the desired solution.

FFC connectors are integrated with two plates; a lower plate constitutes the contact points and an upper plate provides the mechanical strength to securely attach the conductive elements. The contact plates provide efficient contact between the external conductor pad and the lower plate. These contact plates are either prepared explicitly for FFCs or are manufactured from a reference board. Likewise, the upper plate is available in either standard sizes or custom details.

The contact plates are usually secured together by a continuous attachment process. This process includes the use of plastic rivets or screws. Depending on the application, these rivets and screws are generally either securely fastened or removable. Some FFCs have an additional feature in the form of a cover for environmental protection. The covers may be placed over the flat cables for protection from dust, water, oils, and other contaminants.

The connection between the flat cables and the printed boards is made via insertable terminals which mate with the contact plate. The terminals of the flat cable are then fed through the contact plate and into the printed board. These terminals are then soldered into the board and secured. These various methods are used depending on the nature of the application. Some applications require crimping instead of soldering, while other require different methods.

FFCs are also popular in embedded applications due to the small form factor. This type of connector utilizes a secure connection between the board and the flat cable. This connection is made via a male/female terminal. The terminals can be configured on either the board or the flat cable. This allows for extremely high-density connections in a very small space.

FFC/FPC technology offers a variety of benefits for various applications. It is very cost-effective for mass production of printed circuit boards, as the usability profile is higher than when using traditional connection methods. The low profile nature of FFC/FPC makes it ideal for applications involving smaller components. The wide range of sizes gives the flexibility to meet different space requirements. Finally, it can also be configured with covers for additional environmental protection.

In conclusion, FFC/FPC is an effective, cost-efficient technology for printed circuit board applications. Its versatile nature offers a range of benefits for applications ranging from consumer electronics, medical, automotive to industrial. The flat cables and contact plates can be manufactured and customized to suit individual needs, and the secure connection between the board and the flat cable makes it ideal for embedded solutions. FFC/FPC technology is here to stay, as it continues to evolve and address existing market needs.
