Introduction to FFC, FPC Connectors

FFC (Flat Flexible) Connectors are specialized interconnects designed to overcome the problems of wiring space and wiring arrangement posed by traditional wire-based electrical connections. They are especially suitable for use in applications where reducing the number of wires and space consumption is critical, as well as applications where the circuit board needs to fit into a very tight space.As the name indicates, FFC Connectors consist of two flat flexible metal conductive members. These are connected with a plated metal connection that is specially designed to shield the signal from external interference. The connection is made by means of a serrated contact that allows for flexible contact between the two conductive members even when the power is supplied.FPC Connectors is the same as FFC Connectors, but is devoid of contact less structure. FPC Connectors can be made from different materials such as PVC, copper and others, depending on the application. The contacts in FPC Connectors are formed as part of the flat flexible metal strip. They can also be plated with Gold, Nickel and other metals if higher conductivity is needed.

Applications of FFC, FPC Connectors

FFC, FPC Connectors are used in a wide variety of electronic applications, such as:

• Connecting sensor and LCD displays
• Connecting a variety of mobile devices including cell phones, digital cameras and PDAs
• Connecting computer devices such as modems, hard drives, USB ports, sound cards, etc
• As part of a disk drive assembly
• In communications and industrial equipments
• In medical equipments as well as a variety of electronic products

Advantages of FFC, FPC Connectors

FFC, FPC Connectors offer many advantages over traditional wire-based connections in different applications. Advantages include:

• Smaller size and higher density than traditional connectors
• Lightweight due to the flexible contact materials used
• Highly resistant to vibration, shock and corrosion due to their small size and connection location
• Can be used in multiple layers to form a very compact connection
• Each connection can be individually tested before being embedded in the product assembly
• Removable and replaceable contact technology in some designs
• Lower cost of ownership due to lower maintenance & repair

Working Principle of FFC, FPC Connectors

The working principle of FFC, FPC Connectors is simple yet effective. When connecting different components, the two flat flexible conductive elements (known as contacts) slip onto the circuit board edge connector. On the other end, the two contacts on the PCB connector are connected through a plated contact which is created by the contact fingers emerging from the opposite contact. This creates a foam-like shield to shield the signal from outside interference.The flexible contacts in FFC, FPC Connectors allow a snug fit even when the power supply is applied. This ensures a stable connection with minimal power loss.

Conclusion

FFC, FPC Connectors offer many advantages to designers in terms of size reduction, weight reduction, vibration and shock resistance, and lower cost of ownership. They are the perfect option for applications where space and wiring arrangement needs are critical. With their robust construction and reliable connection, FFC, FPC Connectors are sure to be present in many more electronic devices in the future.
