FPC overview

Release date:2021-06-22

       FPC is flexible printed circuit (FPC), also known as flexible circuit board, flexible circuit board, it is favored for its light weight, thin thickness, free bending and folding and other excellent characteristics, but the domestic quality inspection of FPC mainly relies on manual visual inspection, high cost and low efficiency. With the rapid development of the electronic industry, circuit board design tends to be more and more high-precision and high-density, the traditional manual detection method has been unable to meet the production demand, FPC defect automatic detection has become an inevitable trend of industrial development.
       Flexible circuit (FPC) is a technology developed by the United States in the 1970s for the development of space rocket technology. It is a kind of printed circuit with high reliability and excellent flexibility, which is made of polyester film or polyimide as the substrate. By embedding circuit design on the flexible thin plastic sheet, a large number of precision components can be embedded in the narrow and limited space, So as to form flexible circuit. This circuit can be bent and folded at will, light weight, small volume, good heat dissipation, easy installation, breaking through the traditional interconnection technology. In the structure of flexible circuit, the materials are insulating film, conductor and adhesive.
