What are the advantages of FPC flexible circuit board? Now let me tell you

Flexible printed circuit (FPC), also known as Flexible circuit board and flexible circuit board, is favored for its light weight, thin thICkness, free bending and folding and other excellent characteristics. However, the quality inspection of FPC in China mainly depends on manual visual inspection, with high cost and low efficiency. With the rapid development of the electronic industry, the circuit board design tends to be more and more high-precision and high-density, and the traditional manual detection methods can no longer meet the production needs. Automatic detection of FPC defects has become an inevitable trend of industrial development.

Flexible circuit (FPC) is a technology developed by the United States in the 1970s to develop space rocket technology. It is a highly reliable, highly flexible printed circuit made of polyester film or polyimide as the base material. By embedding circuit design on flexible thin plastic sheets, a large number of precision components are embedded in narrow and limited spaces to form flexible circuits. This kind of circuit can be bent at will, folded, light in weight, SMAll in size, good in heat dissipation and convenient in installation, breaking through the traditional interconnection technology. In the structure of flexible circuit, the materials are insulating film, conductor and adhesive.

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, PDA, digital CAMeras, liquid crystal displays and other products.

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, can be arranged arbitrarily, and move in three-dimensional space and scale according to the spatial layout requirements, so as to realize 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 error. As long as the process diagram is checked and approved, all subsequent circuits are the same. The connecting lines are not connected incorrectly to ensure the consistency of the 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 the capacitance, inductance, characteristic impedance, attenuation and delay parameters, and can be designed to have the characteristics of transmission lines and controllable high electrical parameters.

The technology of SMT chip factory can basically meet the product needs of all walks of life, including new energy field, communication field, security field, automobile field, medical field, welding equipment, etc.
