The main advantages of using printed boards

1. Due to the repeatability (reproducibility) and consistency of the graphics, errors in wiring and assembly are reduced, and equipment maintenance, debugging and inspection time are saved;

2. 
   

　　 2. The design can be standardized to facilitate interchange;

　　3. High wiring density, small size and light weight, which is conducive to the miniaturization of electronic equipment;

　　4. Facilitate mechanization and automated production, improve labor productivity and reduce the cost of electronic equipment.

　　 The manufacturing methods of printed boards can be divided into two major categories: subtraction (subtraction) and addition (addition). At present, large-scale industrial production is still dominated by the method of corroding copper foil in the subtraction method
