Connector manufacturers explain the material of fpc interface in detail

The FPC interface is also called a flexible flat cable connector. At present, most of them are used to connect the LCD display to the drive circuit (PCB). The commonly used specification is the 0.4mm fpc interface. But with the development of technology, more and more industries use FPC interface. The connector manufacturer TXGA develops and produces various types of fpc interfaces. They are stocked and sold directly by the original factory.

The FPC interface is connected to the FPC soft flat cable and the device port. The two interfaces and one soft flat cable are collectively called the FPC connector. The constituent materials include:

1. Conductor

FPC connector copper foil is suitable for flexible circuits. It can be electrodeposited or electroplated. One side of the electrodeposited copper foil is smooth, while the surface of the other side is dull. It is a flexible material and can be made in a variety of thicknesses and widths. The matt surface of ed copper foil is often specially treated to improve its bonding ability.

2. Insulating film

There are many types of insulating film materials for FPC connectors, but the most commonly used are polyimide and polyester materials.

3. Adhesive

In addition to bonding insulating films with conductive materials, adhesives can also be used as coatings, protective coatings, and covering layers. The main difference between the two lies in the application mode of using the coated adhesive coating insulating film to form a laminated circuit, and the application of screen printing technology in adhesive coating.
