2, in general, the entire electronic board products must go through the system board and post process, in the boarding process there are several processes is to go through the yellow room, green in the yellow room of the visual effect is better, but This is not the main thing. During SMT soldering, the upper tin and posts and the final AOI calibration are required. These processes all require optical alignment and calibration. The green background has a better recognition effect on the instrument.

3, common red, yellow, green, blue and black. Due to the process problems, the inspection of many lines still depends on the worker's eyes (of course, most of them now use flying probes). There is a galaxy of non-stop galvanizing eyes with bright lights. This is a very tiring job. Green is relatively the most eye-friendly. So most use green.

4. Blue and black are respectively doped with cobalt and carbon, which have certain conductivity, so there is a risk of short circuit. The green PCB is more environmentally friendly and will not release toxic gases when used under high temperature environment.
