Flexible Flat Cables (FFC) and Flexible Printed Circuits (FPC) Connectors are two different technologies for making connections between two flat surfaces. They are used in a variety of applications such as consumer electronics, automotive, data processing, and various other computer applications. The differences between the two technologies can be summarized into four main categories.The first category is form factor or size. FFCs use flat cables that are typically between 0.7mm and 1.2mm thick. These cables are usually profile size and are usually available in different lengths. FPCs are typically thinner, around 0.2mm thick. The physical size of the connection is dependent on the application.The second category is the electrical connection. FFCs are usually used for short term or temporary connections and are not meant for long term or permanent connections. The electrical connections used for FFCs are usually crimped contacts or edge connectors. The electrical connections used for FPCs are usually soldered connections.The third category is the shielding. FFCs usually use an insulated cable that is wrapped around the bare electrical connection. This shielding helps protect the electrical connection from electromagnetic interference. FPCs usually use either an integral shield or a metal foil that is laminated to the FPC.The fourth category is the usability. FFCs are usually used in places where the user may need to change the FPC connection because of a physical damage, either through accidental or intentional damage. FPCs are usually used in locations where the FPC connection does not need to be changed often.In conclusion, FFC and FPC connectors have many differences. The main categories include form factor, electrical connection, shielding, and usability. Each one may be better suited for certain applications. When selecting a FFC or FPC connection it is important to understand the physical and electrical requirements of the application, as well as the environment where the connection will be used.
