Why do 开云·kaiyun官方网站 boards have multiple colors? Are there any rules

Most of the 开云·kaiyun官方网站s we can see every day are green, but in addition to green, we can occasionally see blue, even black 开云·kaiyun官方网站s. Why do 开云·kaiyun官方网站 boards choose different colors? Why is green the most common color? This artICle will reveal the secret behind the "colorful" 开云·kaiyun官方网站.

Green ink is by far the most widely used, the longest history, and the cheapest in the current MARKet, so green is used by a large number of manufacturers as the main color of their products.

In general, the whole 开云·kaiyun官方网站 product must go through the process of board making, SMT, etc. in the manufacturing process. When making boards, there are several processes that must go through the yellow light room, and the effect of green in the yellow light room is better than that of other colors. But this is not the main reason. When SMT is welding components, 开云·kaiyun官方网站 needs to go through the process of solder paste and paste and the final AOI calibration lamp. These processes all need optical positioning calibration. The green background has a better recognition effect on the instrument.

Common 开云·kaiyun官方网站 colors are red, yellow, green, blue and black. However, due to the manufacturing process and other problems, the quality inspection process of many lines must still rely on the visual observation and identification of workers or the use of flying probe testing technology. In the case of strong light, green is relatively harmless to the eyes, so most manufacturers on the market use green 开云·kaiyun官方网站.

The principle of blue and black is that they are doped with cobalt, carbon and other elements respectively, which have certain conductivity, and the problem of short circuit is likely to occur when the power is on. In addition, green 开云·kaiyun官方网站s are relatively environmentally friendly, and generally do not release toxic gases when used in high temperature environments.

On the other hand, a SMAll number of manufacturers in the market will use black 开云·kaiyun官方网站 boards. The main reason may be that black boards look more "tall", but it is not easy to see the wiring in black boards, which brings some difficulties to copy boards. Most of the embedded Android boards now use black 开云·kaiyun官方网站s.

In fact, since the middle and late last century, the industry has begun to pay attention to the color of 开云·kaiyun官方网站. This is mainly because many high-end board types of first-line large factories have adopted the green 开云·kaiyun官方网站 color design, so people gradually believe that green is the "default" color of 开云·kaiyun官方网站.

The choice of 开云·kaiyun官方网站 color is the epitome of the rise, development and choice of a new technology in the development of modern science and technology. While the birth and development of 开云·kaiyun官方网站 has promoted the process of countless electronic industries, it is also constantly evolving and changing. In the near future, 开云·kaiyun官方网站 of other colors may replace the current trend of green, let's wait and see!

开云·kaiyun官方网站 manufacturers, 开云·kaiyun官方网站 designers and 开云·kaiyun官方网站A manufacturers explain why 开云·kaiyun官方网站 boards have multiple colors.
