What is a flexible flat cable? A flexible flat cable is an electrical cable made with flat solid conductors. The flexible flat cable is essential for various applications in the electronics industry. Flexible electronics refer to the technology that enables a device to be more flexible. Its unique properties allow it to fit in different places and can be used to power various electronics. Read on to learn more. Here are some examples of a flexible flat cable.

A flat cable’s pitch refers to the spacing between the wire conductors. This distance indicates the pitch. Different cables have different pitches, but common values are 0.5 mm and 1 inch. The pitch of a cable will indicate its ability to accommodate a variety of applications. In addition, the pitch of a cable will affect its flexibility and strength. For example, high-speed ATA interface cables are made with 0.025-inch pitches and have a 0.1-mm pitch.


If you’re trying to connect two computers or other electronic devices, you may wonder which connector to use. FPCs are ideal for straight-through connections, while FFCs are often layered and impedance controlled.

FPC wiring is a flexible circuit board made from a flexible polymer base coated with a protective polymer coating. Because it’s flexible, you can customize the number and spacing of wires. FFC is especially useful for electronics that require a high degree of flexibility. Flexible solar cells, for example, can be made to fit within the spacecraft’s shell. This circuit board is also lightweight compared to the rigid PCB board.


The similarities between FPCs and FFCs extend to their various applications. For example, both types have copper wires and a thin film of chemically etched copper on one side. They are essential in LCD televisions, printers, cameras, and laptops. In addition, they are ideal in the aerospace industry. However, FPCs are more sophisticated than FFCs. They consist of polyethylene terephthalate (PET), copper wires, and other flexible materials.

Unlike other types of connectors, FPCs have a flat, flexible body with a barrier framework that we can organize after installation. This framework also provides a specific stabilization force. In addition, these connectors are strong and rigid enough to resist shock and vibration. Moreover, they have locking components to lock the connectors. For example, Amphenol makes a vibration-proof FFC and FPC with a 2.49mm pitch.

The Difference Between FPC and FFC?


You may have heard about the terms Flexible flat cable and Flexible circuit. But do you know the difference between these two? How do you know which is better? We’ll explain the differences between these two cables and help you make the right choice for your projects. So, what is the difference between FPC and FFC?

Flexible flat cable

If you’ve ever wondered whether the differences between a flexible flat cable and a traditional round electrical wire are worth the hassle, read on to learn more about the two. Unlike traditional round cables, flexible flat cables are thin and lightweight, making them a popular choice among designers. In addition to helping designers save space, they can add an innovative touch to their designs.

Pitch is the primary difference between a flexible flat and a standard flat cable. Pitch is a measurement of the distance between the centers of two adjacent wire conductors. These cables are often helpful in medical products, industrial automation, pulp and paper, festoon systems, packaging, and semiconductor products. They are also widely used in stereos and scanners, with many other applications. You can find them just about everywhere in modern electronics.

Flexible circuit

In contrast to rigid circuits, flexible circuits can be flexed and maintain their form. They consist of a thin insulating polymer film with a pattern of conductive traces. They have been in use since the Second World War, but their popularity is growing today. There are two main types of flexible circuits: single-sided and double-sided. Single-sided flex circuits have only one metal layer. They add Polyimide or FR4 overlays for added insulation and protection against environmental degradation.

Polymer thick film flex circuits are a subtype of the flexible circuit. We manufacture them by printing the circuit elements onto a thin polymer film. The result is a thin, flexible layer of electrical components. Polymer thick film flex circuits are typically single conductor layer structures, though two or more layers can be printed in a sequence separated by insulating layers. While they are generally less flexible, we can make polymer flex circuits with varying amounts of metal.

There are many advantages of FFC over FPC for electronic enthusiasts. These cables feature a wide range of capabilities and components. As a result, users often feel confused when choosing which type of cable to use. FFC cables are commonly helpful for high-density electronic applications.

The construction material is the main difference between an FPC and an affixed FFC cable. FPCs are thinner and have thinner conductor layers. FFCs are helpful in LCDs and motherboards. FPCs are made of copper, coverlay, and PI and are customizable in shape and pattern. We can bundle these types of cables together to fit a variety of applications.


In general, FFC and FCCL cables are similar to each other, but they differ in their cost and applications. We can make these cables with single or double-sided copper wires. They require a chemical etching process and have various layers of coating. The FCCL process produces thicker FFCs. However, some companies use both types of cables for specific projects. When choosing the type of cable to use, consider each material’s application and cost.

Molex offers a line of FFC/FPC connectors. The line of connectors offers a wide variety of profiles, including those with push-style and flip-style actuators. These connectors also come in higher-density versions. A common application for FFC/FPC connectors is in medical equipment. Its versatility allows it to work with different types of cable styles and different circuit sizes.


Amphenol offers reliable, flexible, and high-performance connectors for connecting FFC/FPC circuits. The company’s micro flex connectors are available in various sizes and pitches, making them ideal for various industrial applications. Other FFC/FPC connectors available from Amphenol include ClincherTM and DuflexTM, which are excellent for industrial and modulation applications and shock and vibration-prone environments.

In general, FPC cables and connectors cost less than FFC connectors. Companies concerned with costs often choose FFC designs, but they are more practical. The differences between the two are not so noticeable, but they are essential to know. If you’re looking for a high-quality connector, look for one with an internal FPC connector with a 0.3mm pitch.


You may have heard of Flexible Printed Circuits (FFC), but you might wonder what the difference between them is. These circuits are made from copper and polyimide material and are flexible enough to handle harsh conditions. These circuits are often helpful in LCD televisions, laptops, printers, and other applications where space concerns. There are two types of FPCs: single-sided and double-sided.

One of the main differences between FFC and FPC is how they construct. FFCs have straight-through conductors, while FPCs have multiple traces that can be bent, angled, or tied to a shield. As a result, FPCs are more flexible and are ideal for data cables. FPCs can also have varying pinouts and impedance levels. Depending on the application, you may need to choose an FFC or FPC that works well for your application.

FFCs are thicker than FFCs. They consist of two layers of wire, one insulating foil, and one flat copper conductor. FPCs are helpful in tight spaces and for high-speed applications and are often essential in vehicles. However, they are also more difficult to bend, making them less flexible. So if you’re trying to figure out which connector to use for a particular application, consider FPCs.

Flat Flexible Cables can be helpful in several applications. For example, LCDs and other electronic devices may connect using FFCs. A standard FFC will have one contact on each end, while FFCs with opposite contacts require a connector.
