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.

　　 In which aspects 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.

　　What is PCB

　　PCB (Printed Circuit Board), the Chinese name is printed circuit board, printed circuit board for short, is one of the important parts of the electronics industry.

Almost every kind of electronic equipment, from electronic watches, calculators, to computers, communication electronic equipment, and weapon systems, as long as there are electronic components such as integrated circuits, they must be printed for electrical interconnection.制板。 System board.

　　In the research process of larger electronic products, the basic success factors are the design, documentation and manufacturing of the product's printed board. The design and manufacturing quality of printed boards directly affects the quality and cost of the entire product, and even leads to the success or failure of commercial competition.

　　The role of PCB

After electronic equipment adopts printed boards, due to the consistency of similar printed boards, manual wiring errors can be avoided, and electronic components can be automatically inserted or mounted, automatic soldering, and automatic detection, ensuring the quality of electronic equipment , Improve labor productivity, reduce costs, and facilitate maintenance.

　　PCB development

　　 printed boards have developed from single-layer to double-sided, multilayer and flexible, and still maintain their respective development trends. Due to the continuous development of high precision, high density and high reliability, continuous reduction in size, cost reduction, and performance improvement, the printed circuit board will still maintain a strong vitality in the future development of electronic equipment.

The domestic and foreign discussions on the future development trends of printed board manufacturing technology are basically the same, that is, to high density, high precision, fine aperture, fine wire, fine pitch, high reliability, multilayer, high-speed transmission, light weight, The development of the thin type, in terms of production, simultaneously increases productivity, reduces costs, reduces pollution, and adapts to the development of multi-variety, small-batch production. The technical development level of the printed circuit is generally represented by the line width, aperture, and thickness/aperture ratio of the printed board.

　　In recent years, the consumer electronics market, led by mobile electronic devices such as smart phones and tablet computers, has grown rapidly, and the trend toward miniaturization and thinning of devices has become more obvious.
