What Is A Flexible Circuit Board

Flexible Printed Circuit (FPC for short) is a highly reliable and excellent flexible printed circuit board made of polyimide or polyester film. It has the characteristics of high wiring density, light weight, thin thickness and good bendability.

product description

Flexible printed circuit board (Flexible Printed Circuit, FPC), also known as flexible circuit board, flexible circuit board, is favored for its excellent characteristics such as light weight, thin thickness, free bending and folding... However, the domestic quality inspection of FPC is still It mainly relies on manual visual inspection, which is costly and inefficient. With the rapid development of the electronics industry, the design of circuit boards is becoming more and more high-precision and high-density, and the traditional manual detection methods can no longer meet the production needs. FPC defect automatic detection has become an inevitable trend of industrial development. [1]

Flexible circuit (FPC) is a technology developed by the United States for the development of aerospace rocket technology in the 1970s. It is made of polyester film or polyimide as a base material with high reliability and excellent flexibility. By embedding circuit design on a flexible thin plastic sheet, a large number of precision components can be stacked in a narrow and limited space to form a flexible flexible circuit. This kind of circuit can be bent and folded at will, light weight, small size, good heat dissipation, convenient installation, breaking through the traditional interconnection technology. In the structure of the flexible circuit, the constituent materials are insulating films, conductors and adhesives
