Why is green used in the production of PCB circuit boards?

　　(1) Introduction of professional PCB circuit board production companies in China: Green ink is currently the most widely used and has the longest history, and it is also cheap in the current market. Therefore, green is widely used by manufacturers as the main color of their products.

　　(2) Usually, during the production of PCB circuit boards by PCB sampling companies, there are several processes that must go through the yellow light chamber because the effect of green in the yellow light chamber is better than other colors, but this is not the main reason. When soldering components in SMT, the production of PCB circuit boards involves the process of applying solder paste and mounting, as well as the final AOI calibration lamp. These processes require optical positioning calibration, and a green background color is more effective for instrument recognition.

　　What are the common colors used in the production of PCB circuit boards?

　　(1) The common colors for PCB circuit board production are red, yellow, green, blue, and black. However, due to manufacturing processes and other issues, many quality inspection processes for lines still rely on workers' visual observation and recognition (currently mostly using flying needle testing technology). Staring at the board continuously under strong light is a very tiring process, and green is relatively the least harmful to the eyes. Therefore, most manufacturers in the market currently use green PCBs.

　　(2) Introduction of well-known domestic PCB circuit board manufacturers: The principle of blue and black is that they are respectively doped with cobalt and carbon lamp elements, which have certain conductivity and are likely to cause short circuits when powered on. Moreover, the production of green PCB circuit boards is relatively environmentally friendly. When used in high temperature environments, toxic gases are generally not released
