Printed circuit board features
3.1.2 characteristics of printed circuit boards
In electronic equipment, the main function of the printed circuit board: 1 provides the necessary mechanical support for the various components of the circuit. The circuit can work more stably and reliably. It realizes the wiring and electrical connection between various components and provides easily recognizable characters and graphics, which is easy to install, check and debug. In addition, the printed circuit board also has the following characteristics.
1) the PCB can ensure the consistency, reliability and stability of the manufactured products, which can greatly reduce the wiring errors and thus improve the assembly quality of the whole machine.
2) it is suitable for realizing automation in the whole machine assembly process, suitable for mass production, reducing the cost of the product and improving the efficiency of the whole machine assembly. It can not only realize the design standardization and machine unit, but also be convenient for maintenance.
The assembly and application of printed circuit boards do not require skilled workers and reduce the cost of training operators. (4) High density, small volume and light weight, which is helpful for the realization of lightweight and miniaturization of electronic equipment.
It also has the ability to continue to expand, to add printed components or directly encapsulate circuits into a fixed function
Component.
Its disadvantage is that the manufacturing process is more complicated and the single or small batch production is not economical.
