Common PCB colors are red, yellow, green, blue and black. At present, manufacturing process is limited; the quality inspection of many lines has to rely on the visual observation and recognition of the workers (of course, most of the current use of flying needle testing technology). In the case of strong light, eyes keep staring at the board, this is a very tired work, relatively speaking, and green is the least harmful to your eyes, so most manufacturers use green PCB.
The principle of blue and black is that it is doped with cobalt and carbon lamp elements respectively, it has certain electric conductivity, it is likely to have a short circuit problem in the case of electrification, and the green PCB is relatively environmentally friendly, when it is used in high temperature environment. Toxic gases are generally not released.
There are also a small number of manufacturers in the market will use black PCB board. The main reason is that it looks a bit high-end, and the black board is not easy to see the wiring, which makes it difficult to copy the board. Embedded boards are black PCB.
Since about the middle and late last century, the industry has begun to pay attention to the color problem of PCB boards, many of large factories have adopted green PCB color. So people are slowly thinking that if the PCB color is green, it must be high-end. In fact, it is better to adopt green PCB.(online pcb printing)
