1. What is the difference between FFC and FPC connectors?
The main differences between FFC connectors and FPC connectors are in design, application, and performance.
Design Differences
FPC connectors: usually have a multi-layer structure and complex circuit design, are made of conductive materials, and are connected to circuit boards by welding, crimping, etc. FPC connectors are suitable for circuit boards of various shapes and sizes, have extremely high flexibility, and can adapt to different bending and twisting requirements.
FFC connectors: The structure is relatively simple, mainly composed of insulating materials and conductive materials, and are connected to cables by crimping or plugging. FFC connectors are usually used to connect components such as display screens, touch screens, and keyboards. Their flat design makes the cable more stable and reliable during the connection process. -
2. What is FFC?
FFC (Flexible Flat Cable) is a flexible flat cable, usually composed of flat and soft conductors, such as tinned pure copper wire, made by high-temperature bonding of very thin and flexible adhesive film or paper film 1. FFC has the characteristics of flexibility, lightness, bendability, and anti-twisting. It is widely used in electronic devices as a bridge to connect various components, such as connecting displays and motherboards, touch screens and displays, battery components and control circuit boards. Due to its flexibility and bendability, FFC can achieve more flexible design, optimize the internal space of the device, and has the advantages of small size, light weight, and low cost.

3. What is the rated voltage of FFC?
The rated voltage of FFC is 300V.
FFC cable, also known as Flexible Flat Cable, is a flexible flat cable that is widely used in internal connections of electronic devices. Its main specifications and special features include:
Operating temperature: 80°C
Conductor: 32-16AWG (0.03-1.31mm²) tinned or bare copper strands
Insulation: PVC
Pitch: Common pitches are 0.5mm, 0.8mm, 1.0mm, 1.25mm, 1.27mm, 1.5mm, 2.0mm and 2.54mm
Acid and alkali resistance, oil resistance, heat resistance, moisture resistance, mildew resistance and other characteristics
FFC cables are widely used for data transmission between mobile parts and motherboards, between PCB boards and in miniaturized electrical equipment due to their small size, light weight and high flexibility.

4. What is the difference between flexible PCB and FPC?
There are some differences between flexible PCB (FPC) and flexible circuit board (FPC) in definition and application scenarios.
Definition and materials
Flexible PCB (FPC): Flexible PCB is a type of flexible circuit board, usually made of flexible substrates such as polyimide (PI) or polyester film (PET). This material makes FPC have good flexibility and bendability, can move and stretch freely in three-dimensional space, and is suitable for electronic products that require high density, miniaturization and high reliability.
Flexible circuit board (FPC): Flexible circuit board is a printed circuit board made of polyimide or polyester film as the substrate, with high reliability and excellent flexibility. It has the characteristics of high wiring density, light weight, thin thickness, good bending, and can withstand millions of dynamic bending without damaging the wires.
