Technical Field

[0001] The utility model relates to the technical field of FPC, in particular to a punching machine for processing FPC. Background Art

[0002] Flexible circuit board is a kind of printed circuit board with high reliability and excellent flexibility made of polyimide or polyester film as the substrate. It has the characteristics of high wiring density, light weight, thin thickness and good bending. Flexible circuit board, also known as soft circuit board, flexible circuit board, is favored for its excellent characteristics such as light weight, thin thickness, free bending and folding..., but the quality inspection of FPC in China still mainly relies on manual visual inspection, which is costly and inefficient. With the rapid development of the electronics industry, circuit board design is becoming more and more high-precision and high-density. Traditional manual inspection methods can no longer meet production needs. FPC defect automation inspection has become an inevitable trend in 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 printed circuit with high reliability and excellent flexibility made of polyester film or polyimide as the substrate. By embedding the circuit design on the bendable thin plastic sheet, a large number of precision components can be stacked in a narrow and limited space, thus forming a bendable flexible circuit. This kind of circuit can be bent and folded at will, is light in weight, small in size, has good heat dissipation, and is easy to install, breaking through the traditional interconnection technology. In the structure of the flexible circuit, the materials are insulating film, conductor and adhesive;
