FFC, FPC Connectors and their Applications and Working Principles

FFC (Flat Flexible) Connectors are widely used in the field of electronic information and communication, transmission of digital and analog signals, and electrical interconnection between printed circuit boards (PCBs). They are designed to be durable, reliable connectors for high-end applications, particularly in industrial applications.

Types of FFC Connectors

There are several types of FFC connectors available for different applications from basic surface mount flat flex cable connectors to pin header connectors. The most commonly used types are:

• Surface mount FFC connectors – These include flat flex cable connector groups, such as 0.50mm, 0.635mm, and 0.80 mm, with 1 to 60 terminals. These are designed for use in small spaces, and are suitable for single- or double-sided printed circuit boards.
• Bend-resistant FFC connectors – These connectors have a bend-resistant construction, and are able to tolerate frequent flexing operations. They are suitable for SIMM sockets and computer motherboards.
• High temperature FFC connectors – These high temperature FFC connectors have soldering pins that heat up to withstand temperatures of up to 250°C (600°F). They are suitable for automotive and other harsh environment applications.

Applications of FFC Connectors

FFC connectors are commonly used in a wide range of applications, including:

• Computer and mobile phones
• Electronic toys and game consoles
• Domestic appliances
• Automotive, industrial, and medical equipment
• Hard disk drives

Solution for Flexible Cable Assemblies

FFC connectors are used in FPC (flexible printed circuit) assemblies, which are designed to replace discrete wiring or rigid cable assemblies. FPCs are flexible, and have many advantages, such as higher reliability, lower mating force, and improved signal integrity.

Working Principles of FFC Connectors

FFC connectors use flat flex cable, which is typically a single or double-sided strip of flexible dielectric material with copper conductors embedded within. The cable is connected to the FFC connector using a standard connector locking mechanism. When electrical current is applied to the flat cable, the copper conductors create a continuous circuit between the terminals of the FFC connector and the PCB.

In addition, FFC connectors employ a range of design features to ensure reliable operation in harsh conditions, including contact plating material, contact retention force, contact spacing, contact design, solder joints, and cable strain relief.

Conclusion

FFC connectors are widely used in a wide range of applications, from consumer electronics to automotive and medical equipment. They are designed to be durable, reliable connectors with high performance, and offer advantages such as flexibility and improved signal integrity. With their many design features, they are designed to ensure reliable operation even in harsh conditions.
