They are all circuit boards, what is the difference between FPC and PCB?

FPC (flexible circuit board) is a kind of PCB, also known as "soft board".

FPC is made of flexible substrates such as polyimide or polyester film. It has the advantages of high wiring density, light weight, thin thickness, flexibility, and high flexibility. It can withstand millions of dynamic bending without damaging the wires. , According to the space layout requirements, it can move and expand arbitrarily, realize three-dimensional assembly, and achieve the effect of integration of component assembly and wire connection. It has advantages that other types of circuit boards cannot match.

　　FPC's future development

　　 Based on the vast FPC market in China, large companies from Japan, the United States, and Taiwan countries and regions have all set up factories in China. By 2012, flexible circuit boards, like rigid circuit boards, have achieved great development. However, if a new product follows the "start-development-climax-decline-elimination" rule, FPC is now in the region between climax and decline. Before there is a product that can replace the flexible board, the flexible board must continue to occupy the market share , Only innovation, only innovation can make it jump out of this vicious circle.

　　 Where will FPC continue to innovate in the future?

　　1, thickness. The thickness of FPC is more flexible and thinner;

　　2, folding resistance. The ability to bend is an inherent characteristic of FPC. In the future, FPC will be more resistant to folding, exceeding 10,000 times. Of course, this requires a high-quality substrate;

　　 3. Price. At this stage, the price of FPC is much higher than that of PCB. If the price of FPC comes down, the market will definitely be much broader.

　　4. The level of craftsmanship. In order to meet the requirements of many aspects, the process of FPC is upgraded to meet higher requirements with small aperture and small line width/line spacing.
