The question most asked by many newcomers is: Why is the color of pcb manufacturing circuit boards mostly green? Today, PCB engineers will answer this question for you.

1. Green ink is by far the most widely used, the longest used, and the cheapest on the market, so green is used as the main color of PCB products by a large number of manufacturers.
2. Under normal circumstances, in the process of PCB circuit board production, there are several processes that must go through the yellow light room, because the effect of green in the yellow light room is better than other colors. In addition, when soldering components in SMT, the production of pcb circuit boards has to go through solder paste and post film, and the final AOI calibration lamp process, which requires optical positioning and calibration. The board with a green background color can identify the instrument. The effect is better.
3. The production of pcb circuit boards is not necessarily green, it depends on what color the designer wants to make it, then what color it is. The colors of common pcb circuit boards are red, yellow, green, blue and black. However, due to problems such as the production process, the production workers stare at the board for a long time under strong light, which is easy to cause eye fatigue. Relatively speaking, green is the least harmful to the eyes.
4. Compared with other colors, the production of green pcb circuit boards is very environmentally friendly. When used in a high temperature environment, it generally does not release toxic gases.
The above is the reason why most of the PCB circuit board colors are green. It is recommended that customers and friends choose green as much as possible when making pcb assembly prototype circuit boards, because the price of green is more favorable.
