At present, there are still many buyers who have doubts about the color of each PCB. What color PCB is high-quality, what effect does the color of the PCB board have on the performance of the product, and other similar questions, the following article will help you know the color difference and use of pcb circuit boards.
First of all, as a printed circuit board, PCB mainly provides interconnection between electronic components. There is no direct relationship between color and performance, and the difference in pigments does not affect the performance of electrical appliances. The performance of the PCB board is determined by factors such as the material used (high Q value), the wiring design and the number of layers of the board. However, in the process of washing the PCB, black is the most likely to cause color difference. If the raw materials and manufacturing process used by the PCB factory are slightly different, the PCB defect rate will increase due to the color difference. 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, a PCB substrate 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.
As the circuit traces of the black PCB are difficult to identify, it will increase the difficulty of repair and debugging in the R&D and after-sales stages. Generally, if there is no brand with profound RD (R&D) designers and a strong maintenance team, it is not easy to use a black PCB. of. 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.
Most of the market uses red PCB, green PCB, or blue, black PCB board is generally used in high-end or top flagship products, so it is not common.
