What are the advantages of FPC flexible circuit board

In the electronic product processing industry, the circuit board has three branches: hard and soft. The traditional circuit board is generally a rigid circuit board. The flexible circuit board is a kind of printed circuit board with special functions, mainly used in mobile phones, laptops, PDAs, digital cameras, liquid crystal displays and other products. What are the advantages of FPC flexible circuit board? Here is an introduction for you

FPC flexible circuit board is a printed circuit made of flexible insulating substrate, which has many advantages that hard printed circuit board does not have:

1. Free bending, curling and folding, which can be arranged arbitrarily according to the spatial layout requirements, and moved in three-dimensional space and scale, so as to achieve the integration of assembly and wiring of components, which can be flexible

2. Even in the assembly, the use of steel wire rope, the flat section of FPC soft plate conductor, the reduction of wire diameter, and the formation of the shell make the equipment structure more compact and reasonable, which can not only reduce the volume of electronic products, but also reduce a lot of weight, to meet the needs of high-density and miniaturization development of electronic products, and the development direction of high reliability

3. FPC soft board is used to eliminate wiring errors. As long as the process diagram is checked and approved, all subsequent circuits are the same. There is no wrong connection when connecting wires to ensure the consistency of connection

4. When FPC soft boards are connected, the connection of X, Y and Z planes can reduce switch interconnection, thus improving the reliability of the whole system and providing convenience for fault inspection

5. According to the requirements, the design of FPC soft board can control capacitance, inductance, characteristic impedance, attenuation and delay parameters, and can be designed into controllable high electrical parameters with transmission line characteristics

This paper introduces the advantages of FPC flexible circuit board. FPC flexible circuit board has the advantages of good elasticity, heat resistance and solderability, easy installation, high wiring density and low comprehensive cost. The combination of hard and soft design also makes up for the lack of flexible base layer with a little component bearing capacity to a certain extent, and its application scope is more and more extensive
