FFC, FPC (Flat Flexible) Connectors

FFC (Flat Flexible Connectors) and FPC (Flat Flexible Printed Circuit) connectors are electrical connector systems that allow for the connection of two printed circuit boards, cables, or flex circuits into a single connection. These connectors offer a range of advantages compared to traditional wire-to-board connections.

SFW21R-5STE1LF Application Field

The SFW21R-5STE1LF is a robust, waterproof, miniaturized flat flexible connector which has a pitch of 1.27mm, and is used for board-to-board and wire-to-board applications in a wide variety of industries and applications. These include industrial control, medical devices, automotive electronics, consumer electronics, robotics, and advanced electronic packaging.

Working Principle

FFC and FPC connectors are made of multiple flexible copper strips that are laminated in plastic material. The flexible copper strips are then connected in series and can be cut in various lengths depending on the application’s needs. The connector also consists of a rigid non-flexible area where two mating connectors can be connected. The connection is made by aligning the copper strip contact points on the two connectors and pressing them together.

FFC and FPC connectors provide excellent electrical performance and vibration resistance, allowing for high-speed data transfer and reliable connections. They are also very low profile, making them ideal for applications with tight space requirements. In addition, they are simple to use and very reliable.

Advantages

FFC and FPC connectors offer a number of advantages compared to traditional wire-to-board connections. These include:

• Simple to use.
• High-speed data transfer.
• Low profile, allowing them to fit in tight spaces.
• Reliable connections even in high-vibration environment.
• Flexible and durable.

Conclusion

FFC and FPC connectors are highly reliable and cost-efficient connections for a wide variety of applications. The SFW21R-5STE1LF is a robust, waterproof, miniaturized flat flexible connector which is used for board-to-board and wire-to-board applications in a wide variety of industries. These connectors offer a number of advantages compared to traditional wire-to-board connections and are simple to use.
