What are the advantages of FPC flexible circuit boards

In the electronic product processing industry, circuit boards have three branches: hard and soft. Traditional circuit boards are generally rigid. Flexible circuit boards are a type of printed circuit board with special functions, mainly used in products such as mobile phones, laptops, PDAs, digital cameras, LCD displays, etc. So what are the advantages of FPC flexible circuit boards? Here is an introduction for you



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



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



2. Even in components, the use of steel wire ropes and the flat cross-section of FPC soft board conductors reduce the wire diameter and form a more compact and reasonable structure with the shell, which not only reduces the volume of electronic products but also reduces a lot of weight, meeting the needs of high-density and miniaturization development of electronic products and the direction of high reliability development



3. Use FPC soft board to eliminate wiring errors. As long as the process diagram is checked and approved, all subsequent circuits are the same. There are no incorrect connections when connecting the wires, ensuring consistency in the connection



When the FPC soft board is connected, the wiring of the X, Y, and Z planes can reduce switch interconnection, thereby improving the reliability of the entire system and providing convenience for fault detection



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 to have the characteristics of transmission line and controllable high electrical parameters



This article introduces the advantages of FPC flexible circuit boards. FPC flexible circuit boards have good elasticity, heat resistance, and solderability, are easy to install, have high wiring density, and low overall cost. The combination of hard and soft design also to some extent makes up for the shortcomings of slightly flexible base layers for component bearing capacity, and their application range is becoming increasingly widespread
