Why are PCB boards mostly green?
The most common question asked by many newcomers to the PCB industry is: Why is the color of the PCB circuit board overwhelmingly green? Today, we're going to answer that question.
First, green ink is by far the most widely used, the longest use time, but also the cheapest on the market, so green is a large number of manufacturers used as the main color of PCB products.
Second, under normal circumstances, pcb circuit board production in the process of making the board, there are several processes must go through the yellow light room, because the effect of green in the yellow light room is better than other colors. In addition, in SMT welding components, pcb circuit board production through the solder paste and patch, as well as the final AOI calibration process, all need optical positioning calibration, with green background color of the board on the instrument recognition effect is better.
Third, pcb circuit board production is not necessarily green, to see the designer want to make it into what color, then it is what color. Common pcb circuit board production colors are red, yellow, green, blue, black. However, due to the production process and other problems, production workers in the case of bright light to stare at the board for a long time, easy to cause eye fatigue, relatively speaking, green on the eyes of the least damage.
Finally, the production of green pcb circuit board is relatively environmentally friendly compared with other colors. When used in a high temperature environment, it generally does not release toxic gases.
