FFC, FPC (Flat Flexible) Connectors

FFCs and FPCs are types of connectors, also referred to as flat flexible connectors. They are widely used to connect PCBs, sensors, displays, power cables, and more in automotive, medical, consumer electronics, and industrial applications.

Types of Flat Flexible Connectors

The two basic types of flat flexible connectors are FFC (Flat Flexible Cable) and FPC (Flexible Printed Circuitry). FFCs are typically used for connecting boards or components, while FPCs are more suitable for connecting flexible and rigid components, such as sensors.

Construction of FFC and FPC

The FFC and FPC both consist of a connection tail with e.g. a 0.5mm pitch, a flexible flat cable the same width as the pitch, a conductor insulated with polyester or polyimide and an ultra-fine connector with contacts.

Application Field and Working Principle

Flat flexible connectors are used in a wide range of applications, including automobiles, medical devices, mobile electronics, robotics, home appliances, and industrial control and automation systems. They are mainly used to connect boards, sensors, and other components. The working principle of FFC and FPC is to use a pressure-sensitive mechanism to produce an electrical connection between two components.

Benefits of FFC and FPC Connectors

FFC and FPC connectors offer several benefits, including:

• High durability - The insulation layer of FFC and FPC is made of polyester or polyimide, which is highly durable and resistant to mechanical and environmental conditions. This makes them an ideal solution for a wide range of demanding applications.
• High flexibility - FFC and FPC connectors are very flexible, allowing for freedom of design and positioning of the components within a product.
• High speed - FFC and FPC connectors offer high-speed operation and provide low signal attenuation.
• Small size - Due to their small size, FFC and FPC connectors are ideal for products that require a compact design.
• Low cost - FFC and FPC connectors are relatively low cost.

Conclusion

FFC and FPC connectors are widely used in a variety of applications, from automotive and medical to consumer electronics and industrial automation. They offer excellent performance, high durability, and a cost-effective solution to connecting components. Additionally, their small size and flexible design allow for greater freedom of design and positioning within a product’s layout.
