When entering a pcb factory, the most common ones are red PCB, green PCB or blue PCB. A small amount of black PCB. Among them, the usage rate of the first three colors is the highest. The boards between different colors have What’s the difference?
PCB, as a printed circuit board, mainly provides interconnection between electronic components. There is no direct relationship between color and performance, and the difference in pigments does not affect electrical properties. The performance of the PCB board is determined by factors such as the material used (high Q value), wiring design and several layers of board. However, in the process of washing PCB, black is the most likely to cause chromatic aberration. If the raw materials and manufacturing processes used by the PCB factory are slightly different, the PCB defect rate will increase due to the chromatic aberration. This directly leads to an increase in production costs.
In fact, the raw materials of PCB are seen everywhere in our daily life, that is, glass fiber and resin. The glass fiber and resin are combined and hardened to become a heat-insulating, insulating, and not easy to bend board, which is the PCB substrate. Of course, PCB substrates made of glass fiber and resin alone cannot conduct signals. Therefore, on the PCB substrate, the manufacturer will cover a layer of copper on the surface, so the PCB substrate can also be called a copper-clad substrate.
But black PCB is more difficult to control, because black PCB circuit traces are illegible, it will increase the difficulty of repair and debugging in the R&D and after-sales stages. Generally, if there are no skilled RD (R&D) designers and powerful maintenance teams Brands will not easily use black PCBs. It can be said that the use of black PCB is an expression of a brand’s confidence in the RD design and post-maintenance team. From the side, it is also a manifestation of the manufacturer’s confidence in its own strength. Kangxin Circuit is familiar with driving black pcb.
Everyone should know after reading. In fact, there is no difference between the different colors of the pcb board, but it is related to the frequency of use. Therefore, you can choose any color freely according to customer needs and combined with the strength of your own manufacturers. The PCB is processed.
