Connector manufacturer explains the composition materials of fpc interface

FPC interfaces, also known as flexible flat cable connectors, are currently mostly used for the connection of LCD displays to drive circuits (PCBs), with commonly used specifications of 0.4mm fpc interfaces. However, with the development of technology, more and more industries use FPC interfaces. The connector manufacturer TXGA develops and produces various types of fpc interfaces, which are in stock and directly sold by the original factory.

The FPC interface connects the FPC flexible cable and the device port. Both interfaces and a flexible cable are collectively referred to as FPC connectors. The constituent materials include:



1. Conductor



FPC connector copper foil is suitable for flexible circuits. It can be electrodeposited or plated. Electrodeposited copper foil has a smooth surface on one side and a dull surface on the other. It is a flexible material that can be made in various thicknesses and widths. The matt surface of ED copper foil is often specially treated to improve its bonding ability.



2. Insulating film



There are various 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 overlays. The main difference between the two lies in the application mode of using a coating to bond a coating insulating film to form a laminated circuit, and the application of screen printing technology in adhesive coating.
