Actually, circuit enthusiasts who have always studied circuits may have this question, which is why the vast majority of circuit boards we use are green? Actually, PCBs are all green, depending on what color the planners want to make them into.

Generally, we choose green because it is less irritating to the eyes, and production and maintenance personnel are less likely to experience eye fatigue and less eye damage when working on PCB boards for a long time. Common colors include yellow, black, and red. All kinds of colors are the paint that will be sprayed on the surface after being manufactured.

Another reason is that due to the commonly used color being green, the factory has spare green paint, so the cost of using oil is relatively low. Moreover, when repairing PCB boards, it is easier to distinguish the differences between different wiring and white, while black and white are relatively difficult to see clearly. Each factory uses two colors to distinguish their product grades and series. For example, Asus, a company that makes computer motherboards, has a low-end yellow board and a high-end blackboard. Yingtai's rebounds are high, while the green rebounds are low-end.

At present, only black PCBs have higher costs than PCBs of other colors, but this does not mean that black PCBs have better electrical functions. Instead, in production, black PCBs have higher difficulty in drilling holes, so the yield rate is relatively lower than other color PCBs.
