The structure
The flexible circuit could be single-sided with a conductor layer made of conductive polymer, a flexible dielectric film, or a metal. It should have termination features that can be accessed from one side only. It could also be fabricated with a protective coating to enhance its performance.
Areas in which FPC is applied
- In places where 3 axes, electrical connections are required, for instance, in a camera.
- In places where flexibility is required, such as in cell phones that require folding.
- Electrical connection in cars, satellites, and rockets
- In electrical connections where space is a major constraint.
Advantages and Disadvantages of FPC Electronics
Advantages
- They are an ideal replacement for rigid boards and connectors
- Flexibles single-sided circuits or highly flexible applications
- Are capable of various configurations.
Disadvantages
- It can be damaged if handled carelessly.
- They are difficult to assemble
- It is difficult to repair and rework
- They can result in increased cost
Application of FPC electronics
They are used in space-saving areas and those that have serviceability constraints, such as computer keyboards. Also, they are used to interconnect components like integrated circuits, capacitors, and resistors, which are used in electronic assemblies.
The FPC electronics are applied in the instrument panels, circuits used in the cabin headliner, and under-hood controls in the automotive industry. They are also widely involved in moving printers and arms carrying as well as in disk drives. In computers, flexible circuits are found in cameras, exercise monitors, calculators, and personal entertainment devices.
The FPC is lightweight and is easy to deploy. This makes them suitable for various applications such as outerwear and backpacks. They are also used in medical devices that require many interconnections, as well as cellular telephones.
