Whether the color determines the performance of the PCB multi-layer circuit board, when a PCB board is obtained, the most vividly seen the color of the board oil, the common colors are green, blue, red and black, etc., some people will question whether it is the color Determine the performance, I will talk about my own understanding of different colors.

       1. Green printing ink is by far the most commonly used, the most historical events, and it is also the most cost-effective in today's sales market. Therefore, green is used by many manufacturers as the key color of their products.

       2. Under normal circumstances, all PCB board products have to go through the entire process of plate making and SMT in the production process. In the case of plate making, there are so many process flows that must go through the white light room. The actual effect of the white light room is better than other colors, but this is not the most critical reason. In the case of SMT welding electronic components, the PCB has to go through the whole process of applying solder paste and post film and the final AOI check lamp. This whole process requires precise positioning and correction of electron optics, with a green background The color is very effective for the identification of equipment.

       3. The common PCB colors are red, yellow, green, blue and black. However, due to the difficulties of processing technology at this stage, many wireframe product quality inspection processes must rely on the observation and identification of employees (naturally most nowadays, laser detection technology is used). Under the condition of strong light, keep your eyes on the board for proofreading. This is a process that requires energy and work. Relatively speaking, green is the least harmful to your eyes. Therefore, most manufacturers in the sales market at this stage use green PCBs. .

       4. The basic principle of dark blue and black is that they are doped with cobalt and carbon lamp elements respectively, and have a certain electrical conductivity. The problem of short-circuit failure is likely to occur in the plug-in state, and the green PCB is relatively still It is environmentally friendly, and it is generally not easy to release harmful gases when used in high-temperature natural environments.

       5. Starting from 2007, everyone began to pay attention to the color of PCB boards, mainly because some first-tier manufacturers adopted black PCB board color design for high-end board types, so everyone slowly thought that the color of PCB board was black is high-end of.

       So since then, manufacturers have slowly begun to use black PCB coatings-an inexplicable reason has caused such an inexplicable phenomenon. No one has thought that the PCB solder mask is black, which means that the motherboard is of good quality. This is completely misleading by the first-line brands using black to identify products and positioning.

       The black board is not easy to see the wiring, which brings a certain degree of difficulty to the copy board. What I learned is that most of the Android embedded boards now use black PCBs. Therefore, manufacturers who dare to use black circuit boards generally have absolute confidence in their team’s technology. In terms of use effects, the performance of both parties is the same. There is no saying that black circuit boards are higher-end in performance than green circuit boards. .

       In summary, the editor believes that buyers can choose the appropriate color according to their own needs.
