Flexible circuit board is also called flexible circuit board (FPC) for short. It is mainly composed of CU (Copper foil) (ED or RA copper foil), A (Adhesive) (acrylic and epoxy resin thermosetting adhesive) ) And PI (Kapton, Polyimide) (polyimide film) composed of circuit boards, has many advantages such as space saving, weight reduction and high flexibility.

The characteristics of flexible circuit boards

The size of the application product is reduced, the space is saved, the weight is greatly reduced, the function is increased, and the cost is reduced.

 

 

It is highly flexible and can be wired three-dimensionally, and the shape can be changed according to space constraints.

Can be folded without affecting signal transmission, anti-static interference.

High and low temperature resistance, flame resistance.

Stable chemical changes, high stability and reliability.

Providing more design solutions for related products can reduce assembly man-hours and errors, and increase the service life of related products.

The role of flexible circuit boards

The function of the soft board can be divided into four types, namely lead wire, printed circuit, connector and multi-function integrated system

Leading circuit: connection between rigid printed circuit boards, three-dimensional circuits, movable circuits, and high-density circuits.

Printed circuit: high-density thin three-dimensional circuit

Connector: low-cost connection between hard boards

Multi-function integration system: integration of hard board lead wires and connectors

 

Application of flexible circuit board

Flexible circuit boards are widely used in commercial electronic equipment, car dashboards, printers, hard disk drives, floppy drives, fax machines, car mobile phones, general phones, notebook computers, cameras, video cameras, CD-ROMs, Hard disks, watches, computers, cameras, medical equipment and other electronic products and equipment.
