How to identify the quality of circuit boards by color? B circuit board mainly provides interconnection between electronic components. Color actually has no direct relationship with performance. Different colors also affect the performance of electrical appliances. The performance of B circuit boards is determined by factors such as the materials used, the layout, and the number of layers on the board. However, in the process of making circuit boards, black is the most likely to cause color difference. If the raw materials and production processes used by the circuit board factory are slightly deviated, the defective rate of B circuit boards will increase due to color difference. This will increase production costs.
B The raw materials of circuit boards are very common in our lives. They are composed of glass fiber and resin. The two are combined and hardened to form a heat-insulating, insulating, and not easily bent board. This is the circuit board substrate. Generally, the B substrate made of glass fiber and resin alone cannot transmit signals, so we will cover the surface with a layer of copper, and therefore we also call the B substrate a copper-clad circuit board.
Since the circuit traces of the black B circuit board are difficult to identify, it will increase the difficulty of maintenance and debugging in the R&D and after-sales stages. Generally, if a brand does not have skilled (R&D) designers and a strong maintenance team, it will not be possible. Will easily use black B. It can be said that the use of black B is a brand's confidence in the design and post-maintenance team. From the side, it is also a reflection of the manufacturer's confidence in its own strength.
