Why is the color of the PCB irrelevant to the quality of the PCB board?
The raw materials of PCB are everywhere in our daily life, that is, glass fiber and resin. The glass fiber is combined with the resin, hardened, and becomes a heat-insulating, insulating, and not easy to bend board, which is the PCB substrate. Of course, the PCB substrate composed of glass fiber and resin alone cannot conduct signals, so on the PCB substrate, the manufacturer will cover the surface with a layer of copper, so the PCB substrate can also be called a copper-clad substrate.
It is easy to make people mistakenly think that PCB color is related to the quality of PCB board: some PCB designs use black, which is easy to cause color difference in the process of PCB washing; If the raw materials used by PCB factory are slightly different from the production process, the PCB defect rate will increase due to the color difference, which directly leads to the increase of production cost. Because the circuit routing of black PCB is difficult to identify, it will increase the difficulty of maintenance and debugging in the r&d and after-sales stage. Generally, brands without profound RD designers and strong maintenance teams will not easily use black PCB. Based on the above reasons, when major manufacturers choose PCB design for their products, most of them use red PCB, green PCB or blue PCB, while black PCB is rarely seen.
In short, the performance of PCB board is determined by the materials used , wiring design and the number of boards; PCB color has nothing to do with the quality of PCB board.
