　　From the iPhone era, almost all mobile phones have used black PCB circuit boards. What prompted this change? What is the special of the black PCB circuit board?

　　Said 1: In the process of washing the PCB circuit board, the black PCB board is the most likely to cause color difference. If the raw materials and self -work processes used by PCB line board manufacturers are slightly deviated, the adverse rate of PCB boards will be increased due to color differences. high. So what should we do?

　　First of all, I have never told me the problem of color difference. The color difference is not a customer assessment item, and it is difficult to quantify. In addition, other colors are more likely to cause color differences compared to black. Because there is a kind of black, it is enough to be as dark as possible, and there are many other colors. For example, green has:

　　Statement 2: Because the circuit wiring of the black PCB circuit board is difficult to identify, it will increase the difficulty of later maintenance and Debug. Generally, if there is no skill in the brands of the designer and the powerful maintenance team of the powerful maintenance team, it will not easily use the Black PCB to easily use the Black PCB Well, this is why only a few high -end brands (such as ASUS) high -end series use the black PCB board -it can be said that the use of black PCB sample is a brand's confidence in RD design and later maintenance teams. It is also a reflection of the line board manufacturer's confidence in his strength.

　　This statement is simply a serious nonsense, which makes sense.

　　First of all, Debug has drawings. The circuit developed by itself. When debugging, you can see the drawings. Besides, who found a signal, leaned on the PCB board to find it.

　　Said 3: In order to prevent plagiarism

　　Brother, have you done 4 -layer board, 6 -layer board, 8 -layer board, 10 -layer board ... 20 layer boards? Even if it is green, do your eyes look at the line?

　　Do you know a multimeter?
