PCB Board Color To Judge The Quality Of PCB Board

      First, as a printed circuit board, PCB mainly provides interconnection between electronic components. There is no direct relationship between color and performance, and it will not affect electrical appliances. Whether the performance of the PCB board is good or not is determined by the materials used (high Q value), wiring design and several layers boards. 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 deviated, the PCB defect rate will increase due to color difference, resulting in increased production costs.

      In fact, the raw materials of PCB are everywhere in our daily life, that is, glass fiber and resin. The glass fiber and resin are combined and hardened to become a kind of heat insulation, insulation, and not easy to bend, this 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.
